1 Overview Chemicals and materials for which occupational exposure poses a health or safety risk are considered hazardous materials at SLAC. Hazardous materials are routinely used and stored at SLAC, and their acquisition, use, handling, storage, and disposal are strictly controlled to provide a safe work environment and protect the health of SLAC personnel and guests.

The hazards associated with chemicals and materials are communicated to personnel and mitigated through the hazard communication (HazCom) program and the chemical hygiene program (CHP). The hazardous materials inventory at SLAC is managed through the use of a comprehensive chemical management services (CMS) system, developed for the specific chemical lifecycle at SLAC and based on the existing supply chain model used to acquire hazardous materials and chemicals. These three components make up the hazardous materials program.

Operations at SLAC include elements covered by the following Occupational Safety and Health Administration (OSHA) standards:

1. Title 29, Code of Federal Regulations, “Labor”, Part 1910, “Occupational Safety and Health Standards”, Section 1450, “Occupational Exposure to Hazardous Chemicals in Laboratories” (29 CFR 1910.1450)

2. Title 29, Code of Federal Regulations, “Labor”, Part 1910, “Occupational Safety and Health Standards”, Section 1200, “Hazard Communication” (29 CFR 1910.1200)

Descriptions of the specifics for these standards are included in sections 4.1.1and 4.1.3. This chapter satisfies the requirements for a written hazard communication program.

This chapter describes the requirements for informing personnel of chemical and material hazards in their work areas and the controls used to mitigate these hazards. The CMS and associated procedures used for inventory control and the requirements for the management of hazardous materials are also described in this chapter. While the role of hazardous materials management in pollution prevention and hazardous waste reduction is described in this chapter, the management of hazardous waste and pollution prevention are covered in detail in Chapter 17, “Hazardous Waste” and Chapter 22, “Waste Minimization and Pollution Prevention”.

1.1 Hazards / Impacts

SLAC operations involving the handling, storage, use, or disposal of hazardous materials may pose a risk to the health and safety of personnel. These hazards must be communicated to all potentially exposed persons. Operations involving potential chemical exposure to personnel must include appropriate hazard controls to ensure exposures are kept below occupational exposure limits. Operations involving the use of hazardous

Chapter 40: Hazardous Materials SLAC Environment, Safety, and Health Manual

materials that may adversely impact the environment or generate hazardous waste must be managed to mitigate impacts through waste reduction and pollution prevention.

2 Scope The requirements of this chapter apply to the purchasing, use, handling, storage, transportation and disposal of all hazardous materials, and apply to all employees, subcontractors, and users.

Radioactive materials are not covered by this chapter. Radioactive material procurement, handling, use, and storage are covered in Chapter 9, “Radiological Safety”.

2.1 Exemptions

2.1.1 Chemical Exemptions

Materials containing hazardous chemicals that are inextricably bound in a product and cannot be released, and consumer products used for the purpose intended by the manufacturer in quantities not greater than those purchased by the average consumer, are exempt from the requirements of this chapter.

3 Implementation The requirements of this chapter take effect January 27, 2010.

4 Requirements

4.1 General

4.1.1 Chemical Management Services

SLAC utilizes the chemical management services (CMS) supply chain model for hazardous materials management. Haas TCM is the SLAC CMS vendor. All chemical purchase must be initiated and fulfilled using the Haas Total Chemical Management Information System (tcmIS), which greatly enhances the ability of SLAC to comply accurately with hazard communication, inventory, and chemical usage reporting obligations.

The industrial hygiene and hazardous materials program managers are notified of all new chemical material requests that are processed using tcmIS. In the event of special hazards associated with the material (for example, highly toxic, carcinogenic, highly flammable, reactive, radioactive), the program managers may contact the requester to require a further review of the material and/or operation associated with the use of the proposed material. This review will verify the intended use of the material includes the necessary


http://www-group.slac.stanford.edu/esh/general/radiological_safety/policies.htm



considerations and controls to ensure it can be stored, used, and disposed of safely and in accordance with any applicable regulations. If the safety and/or environmental issues cannot be resolved, the program managers reserve the right to deny the acquisition of this material. (See Hazardous Materials: Purchasing Procedure and Hazardous Materials: Chemical Screening Criteria.)

No other means of acquiring chemicals for on-site use is permitted without prior management approval and program review. Possible ramifications for purchases made outside of this policy include the following sanctions:

Petty cash purchases: no reimbursement will be issued

P-card purchases: first violation, verbal warning and written warning; second violation, p-card revoked

All purchases: note of infraction(s) placed in annual performance review

4.1.2 Hazard Communication Program

With the exception of areas covered under the chemical hygiene program (see Section 4.1.3, “Chemical Hygiene Program”), all personnel who may be exposed to hazardous materials in their work area are subject to the requirements of the HazCom program. This program requires area managers and supervisors whose personnel may be exposed to hazardous materials to implement the HazCom program in their work area. Hazard communication will include the following elements:

1. Maintaining a material safety data sheet (MSDS) on each hazardous material used or stored at SLAC

2. Providing accurate and complete hazardous material inventory in each work area where hazardous materials are store or used. This can be accomplished through local inventories and/or SLAC inventory.

3. Proper labeling of all hazardous materials

4. Providing appropriate training for all affected personnel

Employees of subcontractors are subject to the HazCom programs of their employers. For hazards located in SLAC areas where subcontractors will be working, the project manager or university technical representative (UTR) must provide HazCom information.

4.1.2.1 Material Safety Data Sheet Access

A current MSDS for each hazardous material used or stored will be maintained in the HazCom module of the tcmIS system, and made available for viewing online through the DOE MSDS viewer. The MSDS viewer allows personnel to view and copy each MSDS in the system and is available to all SLAC employees, users, guests, and subcontractors, 24 hours a day. Managers and supervisors will ensure all personnel working in areas where hazardous materials are used or stored have ready access to the MSDS viewer or make available a hard copy of the MSDS for each hazardous material in their work area.

4.1.2.2 Container Labeling

Hazardous material containers will be labeled meeting the following requirements:

Every hazardous material container will be clearly labeled with the material name and appropriate hazard information. Required label elements (per the OSHA hazard communication standard [29 CFR 1910.1200]) include the following:

– Name and address of the chemical manufacturer, importer, or other responsible party


http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatProcedPurchase.pdf


http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatCriteriaChemScreen.pdf

http://www-group.slac.stanford.edu/esh/groups/cgs/hmaq/hazmat/hazcom.htm

http://www.tcmis.com/tcmis/doe/msds




– Identity of the hazardous chemical(s) contained therein

– Appropriate hazard warnings, or alternatively, words, pictures, symbols (or a combination thereof) that provides information regarding the hazards of the chemicals, and which presents personnel with the specific information regarding the physical and health hazards of the hazardous chemical

Manufacturer-affixed labels will not be removed or defaced on the primary chemical container if it still contains the hazardous material. If a container label is missing or illegible, or if the material is transferred into a secondary container, a secondary hazardous material label must be affixed. These are available through the hazardous materials program manager and Haas on-site customer service representative.

Supervisors and managers will be immediately notified when unlabeled hazardous material containers are discovered. Unlabeled containers that may contain hazardous materials should be assumed to be hazardous. An attempt should be made to determine the contents of the container and a correct label should be affixed to the container. If a determination cannot be made about the contents, the hazardous materials program manager should be contacted.

All new installations of hazardous material pipes and tubes will be labeled in accordance with ASME/ANSI A13.1 requirements.

Custodians responsible for tanks will ensure the tanks are appropriately labeled with the following elements:

1. Name and concentration of the materials contained within the tank

2. NFPA 704 hazard diamond indicating the health, flammability, reactivity, and any special hazards of the material

4.1.2.3 Work Area Hazardous Materials Inventory

A current, accurate, work area hazardous material inventory will be maintained. This can be accomplished through local inventories and/or SLAC inventory. Chemicals purchased before 2006 may not be captured on the SLAC inventory and require manual inventory by work area personnel. All chemicals purchased through Haas can be captured for inventory purposes through the building inventory query tool or procurement records through Haas tcmIS.

4.1.2.4 Training

See Section 4.3.1, “Chemical Worker”, for HazCom program training requirements.

4.1.3 Chemical Hygiene Program

Under the SLAC chemical hygiene program, a written chemical hygiene plan (CHP), is required for all chemical laboratories in which the following conditions are met:

1. Chemical manipulations are carried out on a laboratory scale.

2. Multiple chemical procedures or chemicals are used.

3. Chemical procedures are not part of a production process and do not simulate a production process.

4. Safety equipment and personal protective equipment (PPE) are available and in use.

For a list of affected laboratories, see Hazardous Materials: Chemical Hygiene Program Laboratories List.


http://www.slac.stanford.edu/spires/find/libresource/wwwesh?s=ASME/ANSI_A13.1

http://www.slac.stanford.edu/spires/find/libresource/wwwesh?s=NFPA_704

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatListCHPLabs.pdf


Laboratory safe operating procedures will be written and maintained by the laboratory supervisor. All laboratory personnel will follow these procedures to ensure the safe storage, handling, use, and disposal of hazardous chemicals. The Chemical Hygiene Plan provides guidelines and specific requirements for the development of laboratory specific chemical hygiene plans. Recommended chemical handling practices are provided in Section 4.2.2, “Hazardous Materials Management”, and in chemical-specific safe handling guidelines (see Section 6.1, “Program Documents”).

Prior to working in any laboratory with a CHP, personnel must acknowledge in writing that they have read and are familiar with the laboratory chemical hygiene plan and will comply with the requirements of the plan.

4.1.4 Nanomaterial Management

Prior to the purchase, use, synthesis, or storage of nanomaterials, the Nanomaterial Safety Plan must be reviewed and incorporated into work area procedures. The following materials and activities are covered under this plan:

Engineered nanomaterials, that is, intentionally created – in contrast with natural or incidentally formed – engineered nanomaterials with dimensions of less than 100 nanometers. This definition excludes biomolecules (proteins, nucleic acids, and carbohydrates), and materials for which the occupational exposure limit (OEL) documentation of national consensus or regulatory standards has specifically addressed nanoscale particles for that material.

Nanoparticles, that is, dispersible particles having two or three dimensions greater than 0.001 micrometer (1 nanometer) and smaller than about 0.1 micrometer (100 nanometers) and which may or may not exhibit a size-related intensive property. (See ASTM E2456-2006 for terminology.)

Precursors, intermediates, and wastes used during, or resulting from synthesizing such nanomaterials

Laboratory-scale activities involving chemical containers, reaction vessels, material transfers, and other handling of substances that are designed to be easily and safely manipulated by one person. Laboratory-scale excludes those workplaces the function of which is to produce commercial quantities of materials per 29 CFR 1910.1450(b).

4.1.5 Hazardous Materials Management

4.1.5.1 General Precautions

Prior to the use of any hazardous material or chemical, the MSDS provided by the manufacturer must be reviewed. Hazardous materials and chemicals will be handled carefully at all times, stored in appropriate containers, and transported in carrying devices, and all chemical containers will be labeled in accordance with the requirements of this chapter. Open containers should be closed after use, and unneeded hazardous materials must be returned to storage.

The ESH Division may issue a safe chemical use and handling guideline for a chemical in use at SLAC with particularly hazardous properties. (See Section 6.1, “Program Documents”.)

4.1.5.2 Hazard Controls

To control exposure to material and chemical hazards, personnel who use chemicals and hazardous materials must first evaluate the hazards associated with these chemicals, then identify and implement


http://www-group.slac.stanford.edu/esh/documents/techbas/chp.pdf

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatPlanNano.pdf

http://www.slac.stanford.edu/spires/find/libresource/wwwesh?s=ASTM_E2456_2006



appropriate hazard controls and procedures prior to using these hazardous materials. Personnel selecting hazardous materials for use at SLAC will consider the following hazard controls, in order of preference:

Material/Process Design Selection

– Select the safest chemical for a given job

– Use and store the smallest useful quantities to minimize the amount of material on hand

– Generate the smallest amount of hazardous waste

Engineering Controls

– Provide engineering controls and suitable facilities to minimize hazards

– Use the smallest vessels, apparatus, or equipment practical and safe for a given job

– Complete design review to identify and qualify hazards, evaluate risks, and design appropriate control measures prior to installing equipment or using a chemical

– Use warning devices (horns and flashing lights)

– Comply with manufacturer operating instructions for equipment

Administrative Controls

– Chemical acquisition control and inventory

– Training

– MSDSs

– Labels and signs

– Medical surveillance and certification

Personal Protective Equipment

– Using PPE appropriate for the chemicals involved, such as gloves, coveralls, aprons, indirectly vented goggles, and respirators

4.1.5.3 Chemical Storage Assets

In any single room or laboratory, the maximum quantity of any one hazardous material or chemical should be kept at a minimum. Personnel should rely on just-in-time delivery provided by CMS vendors. Any exceptions to the storage occupancy amounts or permissible exterior storage amounts in the California Fire Code (24 CCR Part 9) must be approved in writing by the fire marshal and the relevant manager of the SLAC directorate. Managers may choose to further limit the amount of hazardous materials and chemicals stored or used at their building, facility or facility area when required to provide a safe work environment for personnel.

In general, there are eight types of chemical storage assets in use at SLAC for storing chemical containers:

1. Bulk storage tanks

2. Tube trailers

3. Flammable material storage cabinets

4. Corrosive material storage cabinets

5. Chemical refrigerators


http://www.slac.stanford.edu/spires/find/libresource/wwwesh?s=CCR_24.9


6. Laboratory hoods and equipment with built-in hazardous materials storage

7. Other “cabinets” used to store lesser hazardous materials

8. Gas racks used to store compressed gas cylinders (See Chapter 38, “Compressed Gas Cylinders”)

For all eight classes, the locations of the assets will be shown on the CMS chemical use maps and area managers and supervisors will designate a custodian for each chemical storage asset. It is the responsibility of the chemical asset custodian to ensure the following requirements are met:

1. The local hazardous materials inventory is correct and up-to-date and made available to the hazardous materials program manager.

2. Chemical assets have been assigned a property control (PC) identification number (other cabinets and gas racks are exempted from this requirement).

3. Required inspections and testing of the assets are performed.

4. Documentation of inspections and testing is maintained.

5. Contact information for the asset custodian (name and extension) must be posted on the asset.

All chemical storage cabinets must be approved storage cabinets (that is, compliant with the California Fire Code (24 CCR Part 9), see Hazardous Materials: Chemical Storage Asset Requirements.)

All chemical storage assets are required to be inspected monthly. (See Hazardous Materials: Storage Inspection Procedure and Form, pdf or Word.)

4.1.5.4 Chemical and Oil Containing Equipment

Chemical- and oil- containing equipment, though not considered a chemical asset, have requirements associated with their use. Oil-filled and chemical process equipment must be evaluated for inclusion in the Hazardous Materials Inventory Statement (HMIS) and appropriate warning labels and signs by the hazardous materials program manager. Equipment containing oil or chemicals must include spill prevention measures effective against any release of material that could impact human health or the environment.

4.1.5.5 Process Safety Analyses

In addition to the safety analysis documentation required by Department of Energy (see Chapter 1, “General Policy and Responsibilities” and Chapter 2, “Work Planning and Control”), SLAC is subject to two regulatory programs covering chemical process safety:

1. OSHA Process Safety Management (29 CFR 1910.119)

2. California Accidental Release Prevention Program (CalARP), administered locally by San Mateo County

These two programs list certain highly hazardous or toxic chemicals and threshold quantities for each. If a facility uses one of these materials in any single process in an amount above the threshold quantity, the facility must prepare process safety management and accidental release prevention documentation for that process, and implement the resulting safety and hazard control recommendations. The industrial hygiene program manager is responsible for the process safety management (PSM) program, and the air quality program manager is responsible for the CalARP program. Any proposed new process at SLAC involving the use of chemicals listed on either the PSM or CalARP lists, or any modification of an existing process using these chemicals, must be reviewed by the appropriate program manager who will perform a threshold

determination analysis. The Hazardous and Experimental Energy Committee (HEEC) will also be consulted. In the event a threshold is exceeded, the line organization must change the process so exposure remains under threshold quantities, or perform the required safety studies and implement controls to satisfy the requirements of the PSM and CalARP programs.

4.1.6 Hazardous Materials Transportation

4.1.6.1 Hazardous Materials Transportation to and from SLAC

Transport of chemicals from an off-site location to SLAC will be accomplished only through the CMS acquisition process. Transportation of hazardous materials from SLAC to off-site locations will be managed and arranged by properly trained shipping and receiving department personnel, using the appropriate shipping containers, labels, and other necessary equipment.

Transportation of hazardous waste from SLAC to off-site locations will be managed and arranged by properly trained Waste Management (WM) Group personnel, using the appropriate shipping containers, labels, and other necessary equipment (see Chapter 17, “Hazardous Waste”).

4.1.6.2 Hazardous Materials Transportation within SLAC

Specific information regarding hazardous materials packaging, labeling, and security is specified in the US Department of Transportation hazardous materials transportation specifications (49 CFR 171 and following). Hazardous Materials: On-site Transportation Requirements describes packaging, labeling, and securing hazardous materials and waste for on-site transportation from one room to another, from one floor in a building to another, or from one building to any other location at SLAC.

4.1.7 Hazardous Materials Contingency Planning

4.1.7.1 Consolidated Contingency Plan

SLAC will prepare and maintain a consolidated hazardous materials contingency plan in the format specified in Section 25503.4 of the California Health and Safety Code (HSC 25503.4) SLAC has developed a consolidated chemical contingency plan (CCCP) to integrate various regulatory requirements for hazardous materials (including hazardous wastes) emergency planning into a single functional document. This single plan approach helps to reduce duplication of effort and needless program development, implementation, and maintenance burdens. This CCCP helps to ensure adequate preparedness with rapid and appropriate response to emergency situations involving hazardous materials. The purpose of this plan is to protect public health; employees, contractors and visitors; and the environment.

4.1.7.2 Spills and Releases

A chemical spill is the release of any hazardous chemical from its primary container that results in an increased risk or potential risk to human health, the environment, and property. Refer to Chapter 16, “Spills”, for detailed information about spills and releases.

Note Preparation is essential to minimizing the hazards caused by a chemical spill. Assemble a chemical spill kit, and understand the hazards associated with the chemicals used and stored in the work area. Consult the MSDS or chemical inventory for more information. Post an emergency telephone call list near the entrance to each work area as appropriate.

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatGuideUsePlan.pdf


4.2.2.2 Chemical Acquisition

All chemical purchases at SLAC are processed through a centralized chemical management and information system called Haas tcmIS. Only employees authorized by their supervisors may place orders for chemicals through tcmIS. Access to the system for ordering privileges must be coordinated through the hazardous materials program manager. SLAC personnel with current ordering privileges are listed on the CMS web site. It should be noted that approval of an order through the approval hierarchy is acknowledgement of financial responsibility and is in effect an approval of the invoice. In addition, contact information for ESH and Haas tcmIS on-site representatives who can assist with this procedure are also included at this web site. Once access is granted and an approval hierarchy is set up for that user, he/she will be trained by the hazardous materials program manager and/or Haas tcmIS on-site customer service representative on how to order and track chemical purchases.

The process description and flow diagram for chemical purchasing Hazardous Materials: Purchasing Flow Chart.

No other means of acquiring chemicals for on-site use is permitted without prior management approval and program review. Possible ramifications for purchases made outside of this policy include the following sanctions:

Petty cash purchases: no reimbursement will be issued

P-card purchases: first violation, verbal warning and written warning; second violation, p-card revoked

All purchases: note of infraction(s) placed in annual performance review

4.2.2.3 Lead Acquisition

Raw metals are not covered by the current implementation of the CMS system. The specific requirements on elemental lead and lead shielding are covered in detail in Chapter 20, “Lead Safety”, and any subsequent clarifications issued by either the hazardous materials or the industrial hygiene program manager (see “Chemical Management Services (CMS): Frequently Asked Questions”).

4.2.2.4 Ethanol Acquisition

The purchase and use of ethanol is regulated by the United States Department of the Treasury, Bureau of Alcohol, Tobacco, and Firearms. There is a federal excise tax on the use of ethanol; however, tax-free alcohol may be used for scientific, medicinal, and mechanical purposes. SLAC receives its research-use ethanol through an agreement with Stanford University as the university has a permit under the tax-free exemption. Users of ethanol can initiate purchase through Haas tcmIS but will be invoiced directly.

4.2.2.5 Hazardous Waste Minimization and Pollution Prevention

Waste minimization is defined as measures that reduce the volume and toxicity of hazardous waste disposed in landfills. Pollution prevention is a broader term that includes waste minimization. Pollution prevention is defined as measures that reduce the generation of non-hazardous and hazardous waste, and prevents deterioration of the earth’s atmosphere, water, land, and biota caused by pollution. Pollution prevention includes resource conservation and spill prevention. Waste minimization and pollution prevention program requirements are provided in Chapter 22, “Waste Minimization and Pollution Prevention”. The waste minimization and pollution prevention program is inextricably bound to the hazardous materials program, as the objectives are the same: to reduce waste and toxicity whenever possible.

http://www-group.slac.stanford.edu/esh/groups/cgs/hmaq/cms/cmsfaq.htm



4.2.2.6 Inspection and Delivery

All chemicals are required to be transported to SLAC by one of two means: by Haas CMS vendor subcontractors or by ethanol delivery personnel. No exceptions are allowed without prior management approval and program review.

Chemical containers shipped to SLAC through the Haas hub will be inspected and bar-coded at the hub prior to their arrival on site. Chemicals directly shipped to SLAC from the manufacturing location and ethanol deliveries will be inspected upon delivery.

Chemical receivers are responsible for inspecting the delivery for accuracy and container integrity before signing the shipping manifest. Shipments containing the wrong material or quantities need to be flagged for return or refund. Damaged containers should not be accepted

4.2.2.7 Chemical Storage

The amount of chemicals stored on site should be kept to a minimum. When storage is necessary the following requirements apply.

Storage Assets

As described in Section 4.1.5.3, “Chemical Storage Assets”, there are eight classes of storage assets in use at SLAC, subject to the stated requirements. Requirements for using storage assets safely are in Hazardous Materials: Chemical Storage Asset Requirements.

Incompatibility

Many chemicals are incompatible with one another and must be kept separate. This can be accomplished by distance or by secondary containment, depending on the type of incompatibility, the severity of any possible reactions, and the quantities of the respective chemicals.

Incompatible materials must be separated when the stored materials are in containers having a capacity of more than five pounds (2.3 kilograms) or 0.5 gallon (1.9 liters). Separation can be accomplished by one of the following techniques:

Segregating incompatible materials storage by a distance of not less than 20 feet (6.1 meters)

Isolating incompatible materials storage by a noncombustible partition extending not less than 18 inches (0.46 meter) above and to the sides of the stored material

Storing liquid and solid materials in hazardous materials storage cabinets

Storing compressed gases in approved gas cabinets or exhausted enclosures

Materials that are incompatible may not be stored within the same cabinet or exhausted enclosure.

Do not store chemicals alphabetically as a general group. Chemicals may be separated into compatible groups and stored alphabetically within those compatible groups. Observe all precautions regarding the storage of incompatible chemicals and refer to the MSDS and any applicable SLAC chemical handling and safe use guidelines. (See Section 6.1, “Program Documents”.) A wall chart listing common chemical incompatibilities is available through SLAC Stores.





The National Oceanic and Atmospheric Administration (NOAA) has made available a reference tool that allows one to identify the reactivity of substances or mixtures of substances. The chemical reactivity worksheet (CRW) is a database of reactivity information for more than 6,000 common hazardous chemicals where one can determine what dangers could arise from accidentally mixing incompatible chemicals.1

Spill Prevention

Spill prevention methods are used because equipment or containers could break, leak, or spill their contents. The type of spill prevention used can vary depending on the material, process and/or quantity. It can include engineered and administrative controls.

Spill containment is one method that can be used to prevent spills and release to the environment. Spill containment can include drip pans, gas cabinets, storm drain mats, absorbent material and double walled piping and tanks, as well as response plans and equipment. Spill containment must be chemically compatible with the hazardous material being stored. It is required if the following conditions are met:

1. Hazardous material could come in contact with an incompatible material (that is, it could produce an incompatible chemical reaction, for example, emitting toxic gas, igniting, or exploding).

2. If it escapes from its primary container it may threaten personnel or the environment (for example, contaminates soil or water, or can enter a floor drain or sink).

Secondary containment is sized spill containment and is required when any hazardous material is stored in single containers in excess of 55 gallons of liquid, 550 pounds for solids, or when the aggregate capacity of multiple vessels exceeds 1,000 gallons (10,000 pounds for solids).

Secondary containment must be designed so that it contains 110 percent of the volume of the primary container. If any storage or use area will hold multiple containers, the secondary containment must hold either 10 percent of the aggregate volume or 150 percent of the largest container, whichever is greater. If the hazardous material is stored in an interior hazardous materials storage room, the secondary containment must also be able to contain 20 minutes of sprinkler flow, at the design flow rate for that area, plus the volume of the chemical container. If the hazardous material is stored in an exterior storage area and open to rainfall, it must be designed to contain the volume of the chemical container plus the volume of a 24-hour rainfall as determined by a 25-year storm and provisions shall be made to drain accumulations of the rainwater.

Incompatible materials will not be stored within the same spill containment. See Hazardous Materials: Secondary Containment Requirements and Chapter 16, “Spills”, for more information.

Time- or Shock-sensitive Chemicals

Because many chemicals cannot be stored indefinitely, the user should establish shelf-life guidelines. Materials whose hazardous properties may change upon storage should be dated when first opened. Chemicals that form peroxides or shock-sensitive characteristics should be marked in accordance with the criteria set forth for unstable, time-sensitive, and pyrophoric materials.

Other Chemical Storage Considerations

Best management practices for the storage of chemicals include the following:

Provide a designated storage place for each chemical and return the chemical to that location after each use.

Store chemicals at or below eye level; keep lids and caps on securely when returning to storage.

Avoid storing chemicals on bench tops, except for chemicals currently being used.

Do not store chemicals in laboratory hoods except for those currently in use.

Do not expose stored chemicals to direct heat or sunlight unless in approved cabinets.

Chemical Storage Inspections

Each chemical storage asset and area will be assigned a custodian, and each custodian is responsible for ensuring that periodic inspections of the asset and area are performed. Informal inspections are expected to occur daily. This simply involves observation of the asset and the chemicals contained therein to ensure that there are no leaks or spills.

A formal documented inspection of hazardous materials storage assets and areas will occur monthly. (See Hazardous Materials: Storage Inspection Procedure and Form, pdf or Word) The custodian is responsible for maintaining these inspection reports for at least one year.

Refer to Chapter 17, “Hazardous Waste”, for information about hazardous waste inspections and the hazardous waste inspection checklist.

In the event there is mixed storage (that is, hazardous materials and waste) in the same storage asset, use the most restrictive checklist and documentation requirements.

4.2.2.8 Labeling and Signs

Labels are used to provide critical health and safety information to personnel handling and using hazardous chemicals and products containing hazardous chemicals. Labels or other forms of warning such as signs must be legible, in English, and prominently displayed on the container. Other languages may be added to convey information as long as the information is presented in English as well. When the marking or labeling is impractical due to the size of the container, other solutions, such as a tray in which the container is located, or a tag attached by a wire loop, may be used. Refer to Chapter 17, “Hazardous Waste”, for an example of approved hazardous materials labels.

4.2.2.9 Hazardous Materials Inventory

The Haas tcmIS is used to track chemicals on site and to maintain inventories. Individuals can request information from the hazardous materials program manager on how to access the system. This inventory will be reconciled annually by ESH staff, with assistance as necessary from the chemical asset custodians, and will be submitted by the hazardous materials program manager to the SLAC CUPA (San Mateo County) to satisfy hazardous material business plan reporting obligations.







4.2.2.10 Chemical Use Reporting

SLAC has reporting requirements for numerous external environment, safety, and health (ESH) programs associated with chemical use, as well as internal reporting programs required by the DOE. Some of the more important programs that require such information include the SLAC annual emissions report under Title V of the Clean Air Act, its hazardous materials business plan, and its toxic release inventory (TRI) submittals. The hazardous materials program manager has the responsibility to establish the necessary Haas tcmIS reporting templates in support of ESH program managers who prepare and submit chemical usage reports using Haas tcmIS reporting capabilities. (Further information is provided in Hazardous Materials: Purchasing Flow Chart.)

4.2.2.11 Sharps Disposal

Sharp objects such as needles, syringes, and razors require storage and handling to prevent accidents to workers. For proper disposal of sharp objects, please see Chapter 46, “Blood-borne Pathogens”. Sharp items that are not contaminated with bodily fluids, but may have been contaminated by a hazardous substance should be treated as hazardous waste, and special consideration should be given to minimize the risk of cuts. Some sharp objects may need additional labeling and handling based on their hazardous and radioactive constituents. Consult the Waste Management Group or the Radiation Protection Department for further guidance and requirements (Chapter 17, “Hazardous Waste”, and Chapter 9, “Radiological Safety”).

4.2.3 Industrial Hygiene

Industrial hygiene (IH) monitoring is the measurement of chemical, physical, and biological hazards in the workplace. Chemical hazards exist when there is a risk of direct skin contact, inhalation, ingestion, or absorption of hazardous chemicals in the form of liquids, solids, vapors, gases, dusts, fumes, or mists. The degree of risk associated with handling a specific chemical depends on the toxicity of the chemical and the magnitude and duration of exposure. Chapter 5, “Industrial Hygiene”, provides all of the applicable information regarding this program and its implementation at SLAC.

4.2.4 Accidental Exposures

4.2.4.1 Inhalation Exposures

Many chemicals can become airborne as gases, mists, vapors, or dusts. Exposure through the respiratory system can be very dangerous because absorption into the blood stream through the lungs occurs quickly. In addition, many materials can damage the nose, throat, and lungs directly. Persons over-exposed to chemicals should immediately be relocated to fresh air and be provided with medical attention. This may include the administration of oxygen as well as other medical treatment. Emergency response should be notified as soon as possible by dialing 911.

4.2.4.2 Eye Contact

Many chemicals will damage the eyes if contact occurs. If a chemical contacts the eyes, immediately flush the eyes with copious amounts of water, preferably at the nearest eyewash station. A minimum of 15 minutes rinse time is required. Emergency response should be notified as soon as possible by dialing 911. Do not stop flushing the eyes until emergency personnel arrive on the scene and inform you to stop flushing.




http://www-group.slac.stanford.edu/esh/hazardous_substances/bloodborne/policies.htm



http://www-group.slac.stanford.edu/esh/hazardous_substances/industrial_hygiene/policies.htm


4.2.4.3 Skin Contact

If a chemical comes into contact with the skin, immediately rinse the affected area with large amounts of running water. This may be done in a sink if the hands are the only portion of the body contacted or under a safety shower if the exposure area is more extensive. Emergency response should be notified as soon as possible by dialing 911 if the chemical is a corrosive or could have been absorbed through the skin. Remove contaminated clothing while under the shower. Remain under the shower until emergency personnel inform you to stop, or for a minimum of 15 minutes.

4.2.4.4 Eyewash and Safety Showers

Eyewash stations and safety showers help protect SLAC personnel after an accidental eye or skin exposure to corrosive or flammable materials. Eyewash stations are required in areas where personnel can come into contact with corrosive liquids or gases. SLAC relies on the departments responsible for areas with eye or skin hazards to inspect and ensure the reliability of eyewash stations and safety showers.

Installation, removal, or change of location for any chemical emergency equipment (such as eye washes and safety showers) must have prior approval by the directorate ESH coordinator or hazardous materials or industrial hygiene program manager.

Where there is a potential for personnel to be exposed to injurious corrosive materials, the line manager will ensure appropriate eyewash and shower equipment is available within the work area. Emergency eyewashes, showers, and drench hoses, however, are not substitutes for proper primary eye and face protection such as safety glasses, chemical splash goggles, face shields, and protective clothing.

Supervisors (or designees) that are responsible for areas where eyewash stations or safety showers exist must know the equipment location, inspect the equipment, provide for equipment maintenance, and notify appropriate personnel to repair or replace the equipment if it is missing, defective, or inoperative.

Below are some of the recommendations and requirements from the ANSI standard (ANSI Z358.1-2004) for eyewash station and safety shower equipment. For more details about inspections and maintenance that are not covered in this summary, please refer to the ANSI standards directly (a copy is available in ESH). The standards summary is provided here as basic reference for supervisors or their designees responsible for equipment maintenance.

Plumbed eyewashes will be flushed weekly to minimize the accumulation of sediment and other obstructions. Safety showers will be flushed monthly. Flush until the fluid runs clear.

Each eyewash station and safety shower will be inspected weekly. Log inspections by marking the inspector’s name and inspection date on a tag attached to the equipment. Inspection tags are available from SLAC Stores. (See Hazardous Materials: Eyewash/Shower Inspection Form, pdf or Word.)

The eyewash station or safety shower must comply with the following requirements:

1. Located as close as possible to the chemical use location, preferably within a travel time of ten seconds from areas where eye or skin hazards are present (consult the ESH Hazardous Materials Group if there are questions about locations and hazards)

2. Clearly marked

3. Protected from freezing conditions

4. Provided with a path of travel free of obstructions, including closed doors

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatFormShowerInspect.pdf

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatFormShowerInspect.doc


5. Installed and maintained with no sharp projections in the operating area

6. On the same floor or level as the hazard

7. Equipped with a valve that can be activated in one second or less, (equipped with a crash bar, lever, or pedal, as opposed to a screw-type valve)

8. Equipped with a hands-free feature that allows for water flow while one’s hands are opening eyelids or removing clothing

9. Capable of flushing both eyes simultaneously (eyewashes only)

10. Protected with nozzle caps or bowl covers (eyewashes only)

11. Capable of delivering no less than 0.4 gallons (1.5 liters) of water per minute for fifteen minutes for eyewashes 20 gallons (75.7 liters) of water per minute for 15 minutes for safety showers

Note Hand-held drench hoses may be installed to supplement an eyewashes or showers, but may not replace them.

Self-contained eyewash units may be used in areas where it is not feasible to install plumbed units. Where the possibility of freezing conditions exists, units will be protected from freezing, or freeze-protected equipment will be installed.

Tepid water will be provided at all newly installed eyewashes and safety showers, and should be provided at existing installations whenever possible. The term tepid is defined by ANSI as moderately warm or lukewarm, but ANSI does not specifically define a temperature range for tepid water. The SLAC ESH Division agrees with the general industry consensus that tepid water should range from 60 to 92°F (15 to 33°C). (See Hazardous Materials: Eyewash/Shower Inspection Procedure and Hazardous Materials: Eyewash/Shower Inspection Form, pdf or Word.)

4.2.4.5 Personal Protective Equipment

The use of personal protective equipment (PPE) is required in some areas at SLAC for protection of workers from various chemical hazards. PPE is not a substitute for adequate engineering or administrative controls and should be used only if no other measures are adequate or feasible. A description of PPE for chemical hazards is provided in Hazardous Materials: Personal Protective Equipment Requirements. Refer to Chapter 19, “Personal Protective Equipment”, for complete requirements related to PPE, including

PPE: Prescription Safety Glasses Purchase and Reimbursement Procedure

PPE: Prescription Safety Glasses Approval Form, pdf or Word

4.2.5 Fire Prevention

The following requirements are specific to fire hazards of hazardous materials. See Chapter 12, “Fire and Life Safety”, for complete information about fire prevention, protection, and suppression.

Take measures to prevent ignition of flammables. Smoking, welding, cutting, grinding, and using open flames or ordinary electric equipment in the vicinity of flammable materials is prohibited. Consult the fire marshal for specific distance requirements. NO SMOKING signs must be posted on or near storage cabinets for flammables and in areas where flammables are stored, handled, or used. NO SMOKING signs and FLAMMABLE signs and labels are available from SLAC Stores.

http://www-group.slac.stanford.edu/esh/general/fire_safety/policies.htm



Anticipate the type of fire extinguisher required should an experiment or other use of chemicals result in a fire. The fire marshal may be contacted for information regarding type, spacing, and location of fire extinguishers.

Equipment and containers dispensing flammable or combustible liquids must be properly bonded and grounded to prevent the accumulation of static and a potential ignition source.

Electrical wiring and equipment in close proximity to flammable and combustible liquids, flammable gases, and flammable solids, must be installed and maintained in accordance with the NFPA National Electrical Code (NFPA 70) and the California Fire Code (24 CCR Part 9). Such operations must be classified appropriately and the appropriate class of electrical equipment must be used (the fire marshal should be consulted to assist in this classification).

An open flame should only be used when necessary and extinguished when it is no longer needed. For additional information see Fire and Life Safety: Fire Prevention Hot Work Procedures.

Personnel working in a chemical area should become familiar with the following information:

– Location and use of the nearest fire extinguishers

– Location and use of the nearest eyewash station and safety shower

– Location and use of any chemical-specific antidotes

– Location and route to the nearest emergency exit

– Location and use of the nearest fire pull box and telephone for emergency notification

– Location and proper method for de-energizing and/or isolation of hazardous equipment or processes

Refer to Fire and Life Safety: Limiting Fire Hazards Guidelines for further information.

4.3 Training

Specific training is required for everyone at SLAC who works with hazardous materials. The training of chemical workers (see Section 5, “Definitions”) is described in this section. The overall training curriculum for hazardous materials is presented in Hazardous Materials: Training Flow Chart.

4.3.1 Chemical Worker

All SLAC employees receive their initial orientation through the following course:

ESH Course 219, Employee Orientation to Environment, Safety and Health (ESH Course 219)

If the worker is a chemical worker or supervises chemical workers, he or she is required to take the following course:

ESH Course 105, Hazardous Materials Management (ESH Course 105)

This course is taken when an employee is first assigned to a chemical worker job.

Non-chemical workers can take the following resource course if they are interested or if they are required to do so by their supervisor.

ESH Course 103, Hazard Communication Awareness (ESH Course 103)



http://www-group.slac.stanford.edu/library/CommunityPages.asphttp:/www.slac.stanford.edu/spires/find/libresource/wwwesh?s=CCR_24.9

http://www-group.slac.stanford.edu/esh/eshmanual/references/fireProcedHotwork.pdf

http://www-group.slac.stanford.edu/esh/eshmanual/references/fireGuideHazard.pdf

http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatFlowTraining.pdf

https://www-internal.slac.stanford.edu/esh-db/training/slaconly/bin/catalog_item.asp?course=219




In addition to ESH Course 105, chemical workers must receive on-the-job training, provided by their supervisor. This training is to familiarize chemical workers with the hazards, controls, and procedures specific to their work area. Personnel will complete both types of training prior to working in areas containing hazardous chemicals. Supervisors are responsible for performing on-the-job training when either the hazards change (for example, new chemicals are introduced), the person’s job tasks change, or if the supervisor becomes aware of new hazards (for example, new information about the chemicals, results of an accident investigation).

Supervisors must ensure that the OJT includes, at a minimum, the following topics:

1. How to access the MSDS for materials in that particular work area

2. Physical and health hazards of the specific chemicals in the work area

3. Measures staff can take to protect themselves from relevant chemical hazards, including the use and limitations of PPE

4. Methods used to detect the presence or release of hazardous chemicals in the work area

User and subcontractor personnel covered under the hazard communication standard are expected to receive hazard communication training provided by their employer prior to starting work at SLAC.

4.3.2 Chemical Hygiene Worker

All personnel who work in laboratories covered by the chemical hygiene program (CHP) must receive specific training in accordance with the CHP. In addition to material covered under ESH Course 105, this includes

Methods and observations used to determine the presence or release of a hazardous chemical, such as monitoring conducted by the ESH Department, continuous monitoring devices, and the visual appearance or odor of hazardous chemicals being used

Measures that lab workers can take to protect themselves from hazards, including appropriate engineering and administrative controls and PPE

Physical and health hazards and environmental aspects in the work area, including flammable and reactive materials, irritants and corrosives, acute poisons, chronic organic toxins, allergens, and genetic toxins

Applicable details of the CHP (that is, the individual elements and its availability), including laboratory-specific operating procedures and protocols

The course will be available as a template and should be modified by the lab manager to make it specific to the applicable lab. The lab worker and lab manager should sign the course certification that documents that lab-specific topics were covered. The frequency for refresher training is not stipulated in OSHA regulations; therefore, departments and divisions are encouraged to evaluate the need for such training on a case-by-case basis and in accordance with other ESH training in the individual’s training plan. User and subcontractor personnel who work in the laboratories covered under the CHP must review and sign those laboratories’ specific procedures.

If working in a CHP laboratory, he or she is required to take the following course:

ESH Course 199, Laboratory User CHP Training (ESH Course 199)



4.3.3 Personal Protective Equipment Training

Following completion of ESH Course 105 and the chemical hygiene program training, all chemical workers are required to take the PPE course:

ESH Course 255, Personal Protective Equipment (ESH Course 255)

No retraining is required, unless there is a new job assignment involving new exposure situations, if the hazards change, or if the supervisor becomes aware of new hazards.

4.3.4 Job- and Chemical-specific Safety Training

Depending upon the results of the SLAC Training Assessment (STA), workers may be required to complete other chemical-related training programs. Refer to Hazardous Materials: Training Flow Chart for when these courses are required and the applicable chapter of this manual for further details.

Hazardous Materials: Purchasing Procedure URL: http://www-group.slac.stanford.edu/esh/eshmanual/references/hazmatProcedPurchase.pdf Revision Record: https://www-internal.slac.stanford.edu/esh/docreview/reports/revisions.asp?ProductID=67 Department: Industrial Hygiene and Information Management Program: Hazardous Materials Authority: ESH Manual, Chapter 40, "Hazardous Material" Date Effective: 19 August 2009

1 Purpose

The purpose of this procedure is to ensure that 1) all chemical purchases are placed and tracked centrally, using the chemical management services (CMS) and Haas tcmIS and 2) new chemicals are screened against an established criteria to support their safe management and use. (See Hazardous Materials: Chemical Screening Criteria.)

2 Scope

This procedure covers adding chemicals to the Haas tcmIS catalog and the associated ESH screening process, as well as ordering chemicals. In the event there are disagreements in the characterization of hazards or appropriate controls as the result of the screening process, it also includes appeal and justification processes.

3 Applicability

This procedure applies to any one who purchases chemicals or needs to add new products to the Haas catalog.

4 Prerequisites

To access the Haas tcmIS system, employees or approved users must be registered with Haas. To initiate registration, contact the hazardous materials program manager.

Ordering is accomplished by a process that involves two levels of system registrants for most purchases:

1. Requester: places orders

2. Financial approver: authorizes purchases

A material safety data sheet (MSDS) must be submitted with all requests to add a new item to the catalog. Additional requirements may be triggered by ESH screening as listed in Section 5.2, “Adding Chemicals to the Catalog”.

Hazardous Materials: Purchasing Procedure

5 Procedures

5.1 Ordering from the Catalog

Step Person Action

1. Chemical user Identifies the responsible requester by doing one of the following

Checks the list of authorized CMS requesters

Contacts the on-site Haas representative

Contacts the hazardous materials program manager to place the order if there isn’t a requester assigned to the workgroup.

2. Chemical user / Authorized CMS Requester

Checks catalog listing for chemical

If the chemical is not listed, submits a catalog add request as described in Section 5.2, “Adding Chemicals to the Catalog”

3. Authorized CMS Requester

Places chemical order through Haas tcmIS

The requesting process results in an e-mail notification to the financial approver

4. Financial approver Approves the order if it is reasonable, within the approved financial limits, and is using the correct account number. Shipment does not occur until the order is approved. Financial approval is approval of the invoice.

5.2 Adding Chemicals to the Catalog

For an illustration of this procedure, see Figure 1.

Step Person Action

1. Authorized CMS requester

If the required chemical is not listed in the catalog, submits a catalog add request. The tcmIS help menu describes each step, including the submission of product specifications and an MSDS.

2. tcmIS Notifies ESH reviewers that a new chemical addition is pending.

Confirms that submitted chemical information (such as the MSDS, supplier, and package size) is current.

3. ESH reviewers Review new chemical request within three business days against approved screening criteria to determine the status of the chemical or product: approved, conditional approval, or rejected (Hazardous Materials: Chemical Screening Criteria)

Fast track approval: chemicals similar to previously approved products may be expedited automatically. To initiate fast track approval for time-sensitive projects, contact the hazardous materials program manager.

If the chemical or product is approved, go to step 10.

4. ESH reviewer(s) Contact the chemical user (and ESH safety coordinator if appropriate) to discuss

Less toxic substitute(s)

Conditional approval contingent on restrictions or controls

Rejection of the request based on established screening criteria

The need for upper management approval for toxic or hazardous mission critical products that otherwise may have been rejected. May result in the hazardous

Step Person Action

material program manager requesting the completion of the justification form (as described in steps 7 through 9).

5. Chemical user Accepts ESH reviewers’ assessment of the chemical and works with directorate or local ESH coordinator to identify and implement controls. ESH will review implementation prior to approval.

6. Chemical user Appeal process: If the chemical user disagrees with the ESH SME assessment on the categorization, restrictions, or mitigations attached to the use of the materials:

Works directly with the SME with whose assessment he/she disagrees. Communicates the issue; includes directorate ESH coordinator and provides supporting documentation and alternative mitigations if necessary.

If the issue is still not resolved, communicates with direct supervisor and site safety officer. The decision at this level is final and binding.

Note: ESH’s primary goal is to support scientific work through the ISEMS process.

Justifying purchase of toxic and hazardous products

7. Chemical user Completes the Hazardous Materials: Toxic and Hazardous Chemical Justification Form (pdf or Word), which requires review by the directorate or local ESH coordinator to verify adequate controls are in place and approval by the associate laboratory director (ALD or designee) for the responsible directorate.

If justification is approved, submits justification form to the hazardous material program manager

If justification is declined, an alternative chemical or product will need to be found

8. Directorate or local ESH coordinator and ALD or designee

Review submitted Hazardous Materials: Toxic and Hazardous Chemical Justification Form and approve or decline.

ESH coordinator review verifies adequate controls are in place.

Management approval is acknowledgement that the use is justified.

9. Hazardous material program manager

Compiles approved justification form and informs tcmIS representative of approved request(s)

Once chemical or product is approved

10. On-site tcmIS representative

Approves catalog addition

11. tcm buyer Obtains pricing for approved request within one business day

12. tcmIS Adds specifications, safety data, conditions of use, and controls, if any, to catalog and notifies requester of approval status

13. Requester Places chemical order through Haas tcmIS as described in Section 5.1, “Ordering from the Catalog”

1 Purpose

All hazardous material requisitions and Haas tcmIS catalog add requests must be reviewed by Environment, Safety, and Health (ESH) prior to purchase. ESH review must be done in a timely manner, and based on clear and transparent criteria that are communicated to, and therefore can be anticipated by, management and staff and made part of the chemical and product selection process

The purpose of chemical screening is to reduce risk by 1) identifying hazards and implementing appropriate controls before a toxic or hazardous material is delivered to the site, or 2) substituting an acceptable alternative that is less hazardous and/or environmentally harmful.

2 Scope

These criteria apply to the screening of requests to add chemicals to the Haas catalog.

For information on how to initiate a new chemical request, see Hazardous Material: Purchasing Procedure and Hazardous Material: Purchasing Flow Chart.

3 Applicability

These criteria are to be used by ESH reviewers to screen all requests to add chemicals to the Haas Total Chemical Management Information System (tcmIS) catalog.

Management and staff can refer to the criteria to make informed chemical and product selections, thereby shortening the review process.

4 Requirements

4.1 Reviewers

Requests for new additions to the Haas catalog are screened by subject matter experts (SMEs) representing various ESH disciplines, which are organized as distinct approval groups as shown in Table 1.

ESH reviewers must have

Comprehensive knowledge of applicable regulatory lists and requirements

Ability to interpret material safety data sheets (MSDSs)

Hazardous Materials: Chemical Screening Criteria

Haas tcmIS ESH approver status

Backup within each group is highly recommended to ensure continuity. Directorate and local ESH coordinators are vital in this review due to their process knowledge and understanding of the organizational needs of the users and existing controls. They can choose to be in the initial review or only participate when line management approval and controls are required. The hazardous materials program manager is the point of contact regarding ESH reviewer assignments.

Table 1 ESH Review Groups and Areas of Responsibility

ESH Discipline / Group Subject or Area of Review Responsibility

Industrial Hygiene (IH) Exposure, nanomaterial safety

Risk Management and Response (RMR) Fire safety, emergency management

Hazardous Waste (HW) Disposal restrictions

Waste Minimization / Pollution Prevention (WM/P2) Preferred purchases (Greener Choice)

Water Industrial wastewater discharge, stormwater discharge, groundwater discharge

Air Quality (AQ) Permitted air emissions, greenhouse gases(GHGs), ozone depleting substances (ODSs), hazardous air pollutants (HAPs)

Radiation Protection (RP) Radioactive and nuclear materials

Chemical Management System (CMS) / Hazardous Materials (HM)

4.2 Chemical Status Determination

Each group will review products against the predefined screening criteria as described below. SMEs will apply their expertise to determine the status of the product. The most restrictive status will apply and will fall into one of the following review results:

Approved. There are no additional controls required. The product has ESH approval for use in the requesting work area.

Conditionally Approved. The product is approved for use with specified conditions. Conditions can include limiting the quantity, restricting use to a project or process, and in the case of a highly hazardous material, documentation that the material is required for mission-critical work with no alternatives available. In this case, the form Hazardous Materials: Toxic and Hazardous Chemical Justification Form (pdf or Word) must be completed and submitted prior to making the product available for purchase. Materials in this category may be initially rejected as a catalog addition until the conditions have been satisfied, at which time they can be resubmitted.

Rejected. The product is rejected and will not be made available for purchase. Justification for rejection can include any of the following:

– The material is highly hazardous and is not mission critical.

– A less hazardous substitute is available.

– The material is highly hazardous and there are no available mitigations.





– The quantities will exceed applicable thresholds that will impact the site due to additional regulatory restrictions and oversight or high cost of implementing new requirements.

– The material is one of the listed banned materials (See Section 4.3.1.2 below).

– The material will be used in a manner that results in unacceptable exposure risks.

4.3 Chemical Categorization

4.3.1.1 Categorization Considerations

For chemical screening purposes, chemicals are divided into the following four categories:

1. Banned

2. Of concern

3. Material-restricted

4. Use-restricted

A description of each category follows. In arriving at a categorization the SME may review various information sources and consider many factors, including the following:

Analysis of the product MSDS

Identification of human toxicity and analysis of potential for exposure

Identification of environmental toxicity and potential exposure, including impacts to air and water quality, soils/land, and climate, including an analysis of environmental persistence and bioaccumulation

Availability of substitutes that deliver required performance

Availability of controls to manage identifiable risks (for example, process design, engineering, administrative, or personal protective equipment)

Consideration of the quantity in use and/or storage

Impacts on mission capability and business costs, including decontamination and disposal costs

Comparison of chemicals or constituents against applicable regulatory and environmental hazard lists such as priority chemicals identified by the United States Environmental Protection Agency (EPA), any agency-specific toxic or hazardous chemical lists, and emerging contaminants identified by the United States Geological Survey (USGS)

4.3.1.2 Categories

Categories provide a review process framework and assist in identifying risk types, such as exposure or environmental release. Understanding the category helps in determining controls so that the material can be used safely.

Note If a hazardous material belongs to more than one category, use the more restrictive .



Table 2 Toxic and Hazardous Materials Categories

Category Description

Banned The following are banned for use at SLAC due to policy and Department of Energy (DOE) or regulatory directives:

Polychlorinated biphenyls (PCBs)

Department of Transportation (DOT) Class 1.1: Explosives (49 CFR 173.50) Explosive substances release pressure, gas, and heat suddenly when they are subjected to shock, heat, or high pressure. Division 1.1: Explosives with a mass explosion hazard: A mass explosion is one which affects almost the entire load instantaneously. Examples: dynamite, TNT, black powder.

Class I ozone-depleting substances (ODSs)

Banned asbestos products (EPA Asbestos Materials Bans: Clarification)

Controlled and listed substances listed in the Stanford University Controlled Substances and Precursor Chemicals Program

Lead paint, lead shot, or lead wool

Of Concern Materials that are judged to pose a higher exposure or environmental risk fall into one of several types as listed below. This category of materials may require justification for use. Safer alternatives should be evaluated.

Highly hazardous materials

These materials present an exposure risk to workers, emergency responders and the surrounding community due to physical and chemical hazards. Chemicals with the following properties are of particular concern:

Highly reactive, water reactive, or pyrophoric (butyllithium solutions in solvents)

Explosive (such as heavy metal azides, perchlorates with heavy metals, picric acid [[f dry], and peroxide-forming substances)

Highly corrosive (concentrated, glacial, fuming acids, concentrated bases)

Highly toxic (cyanide compounds, due to potential generation of HCN gas), isocyanates (especially MDI), chromium (especially Cr+6), cadmium, lead, nickel, beryllium, including Cu-Be alloys

Chemicals with permissible exposure levels (PELs) that are below levels that can be monitored

Occupational Safety and Health Administration (OSHA)-listed hazardous and toxic substances (29 CFR 1910.1000-1052)

OSHA-listed carcinogens, mutagens, teratogens, reproductive toxins per 29 CFR 1910.1003

Proposition 65 (see hazardous materials program manager for current list)

Persistent, bio-accumulative, and toxic pollutants (PBTs)

The EPA’s Persistent Bio-accumulative and Toxic (PBT) Chemical Program addresses chemicals that are a risk due to their persistence, bioaccumulation within the food web, and toxicity to living organisms. PBTs transfer relatively easily among air, water, and land, and span boundaries of regulatory programs, geographic entities, and generations, and so require stringent controls to prevent release into the environment.

Category Description

chemicals (PCs) found in our nation's products and wastes by finding ways to eliminate or substantially reduce their use by recovering or recycling them.

Material-restricted Release of these materials are subject to regulatory thresholds that must not be exceeded and apply to the SLAC site as a whole. Every instance of product use must be tracked by work groups and areas.

Total toxic organics (TTO) must never exceed levels specified in the Solvent Management Plan (SMP). For information, see ESH Manual, Chapter 43, “Industrial Wastewater”.

Hazardous air pollutants listed in ESH Manual, Chapter 30, “Air Quality”

Greenhouse gases such as carbon dioxide, methane, nitrous oxide, and fluorinated gases, many of which have high global warming potential and include SF6, HFCs and PFCs

Ozone-depleting substances, Class I (such as R-11, R-12) will be banned completely by 2010

Non-exempt uses of high volatile organic content (VOC) material, which generally includes products that contain more than 300 grams/liter (g/l) VOCs. Note: Bay Area Air Quality Management District (BAAQMD) regulations include specific limits in the 50-800 g/l range (for example, the limit for lacquer thinner is 50 g/l).

Use-restricted The following materials can only be used in a specified area or processes and/or are kept under specified quantity thresholds. This category includes justified mission-critical materials of concern. Use-restricted products must be highly controlled and may require additional work planning and control procedures.

Radioactive materials and standards require prior approval by the Radiation Protection Department and specified training. See ESH Manual, Chapter 9, “Radiological Safety”.

Nuclear materials listed in Department of Energy Manual 470.4-6, “Nuclear Material Control and Accountability” (DOE M 470.4-6), including nonradioactive deuterium (in any form), tritium, and lithium-6, must be approved by the Radiation Protection Department prior to ordering.

Cyanide salts can be used only within the constraints of the SLAC Risk Management Plan.

Mercury-containing apparatus and equipment cannot be purchased unless the exceptions specified by the California Department of Toxic Substances Control (DTSC) are met (see DTSC Fact Sheet). (See also DTSC’s “Mercury in Thermostats” and California Health and Safety Code, Division 20, Chapter 6.5, Article 10.2.1 [HSC 25214.8.1-25214.8.6].)

Asbestos-containing products can be purchased and used only if approved by the SLAC industrial hygiene group and the air quality program manager.

Materials with a National Fire Protection Association (NFPA) health rating of 3 or 4 must remain at or below quantities that can be “easily and safely manipulated by one person” (29 CFR 1910.1450[b]) unless approved by the fire marshal. Additional assessment may be required if these materials are stored or used in an area above 5 gallons and all must be tracked (inventoried) in one-gallon quantities.

New lead purchases must be justified in part by determining that on-site stock will not meet user/requesters requirements.

Small volumes of material with high VOC content can be approved for specified uses with the approval of the air quality program manager.

Toxic gases can be purchased only if all required controls are in place prior to delivery.

Hazardous Materials: Chemical Storage Asset Requirements Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Bulk Storage Tanks Bulk storage tanks are used at SLAC to store such materials as liquid nitrogen, helium, water treatment chemicals (acids, bases, and proprietary treatment chemicals), propane, isobutene, and others. The installation of hazardous materials bulk storage tanks requires a design review by the fire marshal and the hazardous materials program manager prior to purchase or installation. This review evaluates issues such as sighting, material compatibility, safety controls, pressure relief, seismic design, security, and fire protection.

Tube Trailers Tube trailers contain 20 to 40 long, horizontal, compressed gas cylinders bundled together and connected by manifolds for ease of use, transport, and safety. SLAC currently uses tube trailers for managing hydrogen and helium. Tube trailers are subject to the same seismic safety considerations as bulk tanks and are part of the work scope mentioned above.

It is a Department of Transportation requirement that tube trailers that are in commerce (that is, will be transported over public roads) must be pressure tested every five years. It is the responsibility of the custodian to arrange for this testing. Any exception to the five-year pressure testing requirement must be agreed to in writing by the chairman of the Hazardous Experimental Equipment Committee and the hazardous materials program manager.2

Flammable Container Storage Cabinets Flammable liquid in quantities greater than 10 gallons per use area3 must be stored in approved chemical storage cabinets that meet the design requirements of the California Fire Code4 and NFPA 30-2003, Flammable and Combustible Liquids Code.5 Approved


2 “Hazardous Experimental Equipment Committee”, https://www-internal.slac.stanford.edu/esh/committees/heec/charter.htm

Hazardous Materials: Chemical Storage Asset Requirements

and rated hazardous materials storage cabinets will not be used for ordinary (non-hazardous) storage. Cabinets used to store flammable liquids must meet the following specifications:

The combined total of all liquids will not exceed 120 gallons (454 L). Cabinets used to store flammable liquids must be provided with a conspicuous label

in red letters on contrasting background which reads FLAMMABLE–KEEP FIRE AWAY.

Doors must be well fitted and equipped with a latch and new cabinets must be self-closing.

Cabinets must be seismically braced to a sound structure to prevent dislodgement during an earthquake. The seismic bracing must not penetrate the cabinet in such a way that it would facilitate release of the chemical from the cabinet. The SLAC fire marshal approves seismic bracing of chemical cabinets.

The bottom of the cabinet will be liquid tight to a height of at least two inches (50.8 mm).

Cabinets must be constructed of metal and must be listed (by an accredited listing agency).

The cabinet, including the door, must be double walled with 1.5 inch (38.1 mm) airspace between the walls.

Joints must be riveted or welded and tight-fitting. Unlisted cabinets can be used if approved by the SLAC fire marshal and they

Are constructed from steel with a thickness of at least 0.044 inch (1.12 mm) (18 gauge)

Meet all the requirements of a listed cabinet Combustible material (wood shelves added after the fact, cardboard boxes and paper)

should be minimized or eliminated. The number of flammable liquid storage cabinets and quantity of flammable materials

allowed in a building is regulated and determined by occupancy codes, space between cabinets, and if the building is sprinklered. Contact the SLAC fire marshal for details.

Corrosive Material Storage Cabinets Incompatible corrosives must not be stored in the same cabinet. All corrosive storage cabinets must be conspicuously labeled (letters on contrasting background) with CORROSIVE – ACID or CORROSIVE – BASE, and seismically braced without penetrating the cabinet in such a way that would facilitate release of the contents during an earthquake. All seismic bracing must be approved by the SLAC fire marshal. Cabinets must be listed by an accredited listing agency for the intended storage of corrosives, or meet the following requirements:

various components. See the “SLAC Research Library Community Pages”, http://www-group.slac.stanford.edu/library/CommunityPages.asp, for available standards. A hard copy of the 2007 California Fire Code is available; see http://www.slac.stanford.edu/spires/find/books/www?key=352675.

http://www.slac.stanford.edu/spires/find/books/www?key=352675




The bottom of the cabinet must be liquid tight to a height of at least two inches. Cabinets will be constructed from steel with a thickness of at least 0.044 inch (1.12

mm) (18 gauge). Cabinets, including the door, must be double walled with 1.5-inch air space between

the walls. Joints must be riveted or welded and tight-fitting. Doors must be well fitted, self-closing, and equipped with a self-latching device. Cabinets must be treated or coated on the interior with a material that is non-reactive

with the hazardous material stored, and this treatment or coating must cover the entire interior of the cabinet.

The quantity of corrosive materials allowed in a building is regulated and determined by occupancy codes, space between cabinets, and if the building is sprinklered. Contact the SLAC fire marshal for details.

Laboratory Hoods with Built-in Storage Cabinets Built-in flammable liquid and corrosive material storage cabinets in laboratory hoods are subject to the requirements listed above.

Note For requirements regarding electrical equipment and devices within cabinets used for the storage of hazardous materials, see the National Electrical Code.6

Chemical Refrigerators Ordinary domestic refrigerators and freezers must not be used for storing flammable liquids due to exposure to electrical components (light bulbs, switches, contacts and motors) that can become potential ignition sources. These ignition sources may initiate a fire or an explosion if flammable vapors are present. Refrigerators and freezers for storing flammable liquids and/or temperature sensitive chemicals such as peroxides or epoxies must be designed, constructed and approved for that purpose. Domestic refrigerator/freezers as well as units that have been modified to remove spark sources are not acceptable.

Refrigerators must be labeled on the exterior: CAUTION – FOR CHEMICAL STORAGE ONLY; DO NOT STORE FOOD OR BEVERAGES IN THIS REFRIGERATOR. Labels may be fabricated by users provided the labels are legible and securely affixed to the refrigerator.

The custodian must have a means (manual or automated) to document the storage temperature of the temperature-sensitive materials.

Refrigerators used for food storage in or near work areas (shops and labs) must be labeled with words to the effect of: NOTICE – FOOD MAY BE STORED IN THIS REFRIGERATOR. DO NOT STORE CHEMICALS. Refrigerators used for food and beverage storage that are located in lunch rooms and office buildings, where there is no shop or laboratory type chemical use, do not require any postings.

6 National Fire Protection Association (NFPA), National Electrical Code (NFPA 70-2005) See the “SLAC Research Library Community Pages”, http://www-group.slac.stanford.edu/library/CommunityPages.asp, for available standards. A hard copy of NFPA 70-2005 is available; see http://www.slac.stanford.edu/spires/find/books/www?key=327328.







Other Storage Cabinets It is SLAC policy to allow storage of small quantities of non-flammable, non-highly hazardous materials in other storage cabinets if present in quantities below the exempt limits for that chemical class as provided by the California Fire Code, provided the following conditions are met:7

The cabinet is clearly identified through exterior labeling as containing chemicals. The total quantity of chemicals stored in this fashion per cabinet is less than five

gallons. The cabinet is shown on the CMS map.8 The cabinet is included in the custodian monthly inspections.

Gas Racks and Compressed Gas Cylinder Storage At SLAC, gas cylinders are managed in one of two ways: as individual cylinders or as

groups of gas cylinders known as six-packs (six individual cylinders managed as a unit and connected by manifold). See Chapter 38, “Compressed Gas Cylinders”,9 for more information.

Hazardous Materials: Storage Inspection Procedure and Form Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Monthly documented inspections must be carried out by the chemical asset custodian or designated person for all chemical storage areas and all chemical container types. Inspection results must be kept on record for a minimum of one year, and must be made available to ES&H when requested. The following forms can be adapted to meet the specifications of your storage area, but all basic inspection elements must be included.

Note For inspection requirements for hazardous waste storage areas and waste containers, see Chapter 17, “Hazardous Waste”. 2

Documenting Inspection Results

1. Enter the inspection location on the inspection form and verify that this location is accurately mapped on the CMS chemical use map.3 If the location is new, or information is missing or out of date, contact the hazardous materials program manager or the ESH coordinator to relay any updates.

2. Each month, enter the date, your initials, and place a “check” in every square that applies to this location if the condition meets all safety requirements. The form accommodates 12 inspections, or one full year.

Note If the item does not apply, cross the section out. For example, if there are no compressed gas cylinders (CGCs), mark one large line or “X” through the section. Alternatively, modify the form to more closely meet the conditions of the storage area.

3. If an inspection item requires corrective action, record your observations and comments on the “Observations and Corrective Actions Log” below. Also record the date that the corrective action was completed.

Hazardous Materials: Secondary Containment Requirements Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Secondary containment is required for the storage of all regulated hazardous materials.2 To determine if secondary containment is needed in your case, see Hazardous Materials: Secondary Containment Decision Flow Chart.3

Containment Volume Secondary containment for a single container (tank) will be 110 percent of the primary container. Secondary containment for multiple containers will be 150 percent of the largest container’s volume or 10 percent of the aggregate volumes of all containers, whichever is greater. All secondary containment systems open to rainfall must be able to hold 4.5 inches of rainfall in addition to the required secondary containment volume. All secondary containment systems open to fire sprinkler discharge must be able to hold the discharge from all sprinkler heads over the secondary containment system for 20 minutes in addition to the required secondary containment volume.

Containment Construction Secondary containment must be constructed using materials capable of containing a spill or leak for at least as long as the period between monitoring inspections.

Overfill Protection A means of providing overfill protection for any primary container may be required. This may be an overfill prevention device and/or an attention getting high level alarm.

Separation of Materials Materials that in combination may cause a fire or explosion, or the production of a flammable, toxic, or poisonous gas, or the deterioration of a primary or secondary container will be separated in both the primary and secondary containment so as to avoid intermixing.

Hazardous Materials: Secondary Containment Requirements


Containment Drainage Uncontrolled drainage from a secondary containment system is not allowed. Accumulated rainwater or sprinkler flow water may only be released from a secondary containment system after it has been determined to be uncontaminated. The drainage system must be kept closed or pumps turned off unless the drainage process is monitored.

Other Requirements and Suggestions All storage areas must be secured to prevent access by unauthorized personnel. Secondary containment systems may be covered to prevent rainfall from entering. Constructed secondary containment systems, that is, poured pads with berms, must be tested to ensure that they are leak tight.

Approved coatings must be applied to secondary containment surfaces when spills or leaks would damage or penetrate the uncoated secondary containment system. Secondary containment systems can be provided through the use of trays or drums placed in over-pack drums as long as all provisions of the secondary containment requirements are met.

Hazardous Materials: On-site Transportation Requirements Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

The following provides guidance on packaging, labeling, and securing hazardous materials and waste for on-site transportation from one room to another, from one floor in a building to another, or from one building to any other location at SLAC.

Package hazardous materials and waste in containers that are compatible. Ensure that any cushioning or absorbent material used for packaging is also

compatible with the hazardous material or waste. Use drums that are in good condition and free of rust and major dents. Ensure that drums are not leaking or overfilled before transporting them. Ensure that drum bungs are tight. Carefully inspect pallets before they are loaded. Do not use pallets with cracked or broken slats. Use a drum dolly to place drums on pallets. Secure all drums to the pallet with appropriate strapping material. When packaging small containers of hazardous materials or waste for transportation,

use carrying cases, racks, or trays to keep the containers upright and to minimize shifting during transport.

Do not place incompatible materials in the same tray or carrying case. Protect and cushion glass containers to minimize the risk of breakage. Only containers of chemicals in consumer packaging/quantities may be transported in

personal vehicles. On-site transportation of any other type/quantity of hazardous material must be in a SLAC- or GSA-owned government vehicle. Off-site transportation (that is, on public roads) may only be through a licensed hazardous materials transporter.

Prior to transport, verify that all containers for hazardous materials and waste have proper identification labels.

If a hazardous material or waste has been repackaged, label the new container with the required information.

Containers for hazardous waste must be labeled with the following additional information: Date that the hazardous waste was placed in the container The words HAZARDOUS WASTE Name of the hazardous waste Hazard class




Hazardous Materials: On-site Transportation Requirements


Name and extension of the person responsible for the contents of the container Only hazardous waste containers provided by the Waste Management Group in the

ES&H Division may be used. Verify that hazardous waste containers are labeled with the above information for

their contents before transporting. Secure containers to prevent sliding or shifting during transport using cinch straps to

keep the containers upright. If the containers shift during transport, stop immediately and re-secure the containers. When transporting hazardous materials or waste on site, only SLAC-owned or GSA

government vehicles may be used, not personal vehicles. Ensure that no incompatible materials are present when using passenger vehicles for

transport. Never use mopeds or bicycles to transport hazardous materials or waste. When transporting chemicals by foot:

All flammable and hazardous liquids (at normal temperature and pressure) and all powdered or granular hazardous solids in glass containers should be transferred through corridors and between buildings, using chemical carriers or secondary containers.

Bottle carriers should be used for flammable liquids and corrosive chemicals in glass bottles of two liters or more capacity, or plastic bags for smaller quantities.

Great care should be exercised even when transporting containers within workspaces.

Hazardous Materials: Chemical Use Planning Guidelines Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Before using a new chemical, personnel and supervisors should consider the following:

1. The chemicals or types of chemicals to be used, their hazards and exposure limits, and their proposed storage and use locations. The material safety data sheet (MSDS) is one tool to be used during this evaluation, as are the chemical-specific safe use guidelines.2

2. The building or area occupancy classification and the maximum chemical quantities allowed to ensure exempt or maximum amounts are not exceeded. The following occupancies are present at SLAC:

1. A: assembly areas such as cafeteria and auditorium

2. B: business areas, laboratories under exempt amounts, vocational shops

3. F: factories and industrial areas

4. S-1: moderate hazard storage and service garage

5. S-2: low hazard storage

6. H: laboratories and scientific areas not classified as B, and industrial areas not classified as F due to quantity and hazard of material used or stored

Refer to the California Building Code and California Fire Code, or contact the fire marshal for details on occupancy and storage.3

3. Potential incompatibilities with other processes in the proposed work location

4. The possibility of substituting a less-hazardous substance

Hazardous Materials: Personal Protective Equipment Requirements Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

The following are requirements for personal protective equipment (PPE) specific to working with hazardous materials. For general PPE requirements, including procedures for purchasing, see Chapter 19, “Personal Protective Equipment”.2

Protective Apparel Protective apparel includes coats, aprons, jump suits, special types of boots, shoe covers and gauntlets. Appropriate protective apparel is recommended for most laboratory work, while some tasks require its use. Laboratory apparel should protect against physical hazards yet enable easy execution of physical tasks. In addition to the use of protective apparel, follow the general precautions below regarding regular apparel in the work area:

Do not use or wear excessively loose or torn clothing. Wear shoes at all times. Do not wear perforated shoes, sandals, or cloth sneakers.

Eye and Face Protection Eye and face protection is required in areas where chemicals used could cause injury to the eyes or face upon contact from splashing or pouring. PPE for eye and face protection must be selected in accordance with Title 29, Code of Federal Regulations, Section 1910.133, “Eye and Face Protection” (29 CFR 1910.133),3 and must meet the requirements specified in American National Standards Institute (ANSI) Z87.1-2003, “Practice for Occupational and Educational Eye and Face Protection”.4

Lab supervisors should contact the equipment manufacturers or the industrial hygiene program manager for proper equipment selection. Follow the guidelines below to determine when eye and face protection is required:

See the “SLAC Research Library Community Pages”, http://www-group.slac.stanford.edu/library/CommunityPages.asp, for available standards. A hard copy is available; see http://www.slac.stanford.edu/spires/find/books/www?key=327859.






Hazardous Materials: Personal Protective Equipment Requirements

Safety glasses with permanently attached side shields are required whenever there is a potential for projectile objects in the work area. Safety goggles are required when handling any chemical or process that can create fine dust, fumes, mists, and sprays.

Face shields are required to protect against the hazards identified above. Do not use face shields as a substitute for eye protection. When both face and eye

protection is needed, both types of protective equipment must be used. Eye and face protection is required when radiant energy sources are present in the

work area.

SLAC Stores can provide safety glasses, goggles, and face shields. Employees can purchase prescription safety glasses through the SLAC contract vendor with the approval of their supervisor. SLAC will cover the expense of the actual prescription eyeglasses, but examinations and associated costs are the responsibility of the employee.

Hand Protection Skin contact is a potential source of exposure to toxic materials. For substances that can create a significant exposure to individuals through skin contact, see 29 CFR 1910.1000, Table Z-1, “Limits for Air Contaminants” (see those marked with “skin designation”).5 Appropriate gloves can be selected from safety supply catalogs. Personnel must follow the guidelines below regarding glove use:

Gloves are required whenever there is potential for contact with corrosive or toxic materials, or materials of unknown toxicity.

Select glove material based on chemical resistance, as not all gloves are equally effective in preventing skin exposure to certain chemicals.

Know the time exposure limitations of glove use. Gloves eventually become permeated by chemicals. However, gloves can be used safely for limited time periods if you know specific use and glove characteristics (for example, glove thickness and permeation rate).

Wash gloves after you completed a procedure but before removing them from your hands.

Replace gloves periodically, depending on frequency of use and permeability of the substances.

Ensure gloves are air tight, fill the gloves with air, roll the cuff, and check for leaks. A good summary reference is Stanford University’s “Glove Selection for Laboratory Workers”.6

Hazardous Materials: Personal Protective Equipment Requirements


Respiratory Protection Respiratory protection prevents the inhalation of hazardous vapors or fumes into the lungs. Chemical fume hoods will prevent most exposures. However, when procedures cannot be performed in a fume hood or ventilation is not adequate to provide protection against inhalation hazards, respiratory protection equipment is required. Consult Chapter 29, “Respiratory Protection”,7 for SLAC policy regarding the creation and maintenance of a respirator program.

Respirators may be used at SLAC only after medical evaluation, training, fit-testing, and specific approval of the operation by an ES&H industrial hygienist. Respirators are the last resort for control of exposures and are only to be used when engineering controls, process modification, and other measures are not practical or have proved inadequate.

Hazardous Materials: Eyewash/Shower Inspection Procedure Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Emergency eyewash and safety showers are required in areas where personnel can come into contact with hazardous materials that could harm eyes or skin. All eyewash and shower stations must be inspected weekly and the results logged (see Hazardous Materials: Eyewash/Shower Inspection Form).2

Plumbed Eyewash Stations/Showers Fed from the domestic water supply

1. Ensure eye wash/shower is clear of obstructions and easily visible from all directions (adequate signage).

2. Flush weekly, and record the flushing on the tag attached to the station.

3. What to check when flushing: Eyewash protection caps must be in place and in good condition. The ON/OFF valves must be operational, activated by a single motion. Water flow remains ON when the operator removes his/her hand. Water flows freely and is directed at the proper angles to flush the eyes or body as

appropriate.

4. Run the eyewash/shower for five seconds. The running (or collected) water must be clear: If the water is clear, turn off water and sign the inspection tag. If the water is cloudy, discolored, or contains sediment, start another five-second

flush; stop; and then continue flushing at five-second intervals until the water flushes clear. Then initial the inspection tag.

5. Ensure the water used for flushing was captured in a suitable container (such as a plumbed drain, bucket, or large rolling waste can). If any water was spilled on the floor, dry the area before leaving to prevent a slipping hazard.

Note If a plumbed eyewash station does not run clear after repeated flushings, contact your ES&H coordinator or building manager immediately.

Hazardous Materials: Cryogenic Gas Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Cryogenic gas

Synonyms

Cryogens, liquefied gas, cryogenic liquids

Reactivity and Physical Concerns

Cryogenic liquids are liquefied gases that are kept in their liquid state at very low temperatures. Different cryogens become liquids under different conditions of temperature and pressure, but all have two properties in common: they are extremely cold, and small amounts of liquid can expand into very large volumes of gas. The vapors and gases released from cryogenic liquids also remain very cold. They often condense the moisture in air, creating a highly visible fog. Each cryogenic liquid has its own specific properties but the most commonly used cryogenic liquids can be placed into one of three groups: inert gases (e.g., helium, nitrogen), flammable gases (e.g., hydrogen) and oxidizer (e.g., oxygen). Because of the temperature at which these liquefied gases exist, they can cause other gases to fractionally condense from the atmosphere. For example, liquid helium has a boiling point below that of oxygen (-183ºC), which could result in oxygen being condensed out of air, which in some circumstances can pose a fire risk.

Without adequate venting or pressure-relief devices on the containers, enormous pressures can build up. The pressure can cause an explosion called a boiling liquid expanding vapor explosion.

Exposure Hazards

Routes of Exposure

Inhalation, ingestion, skin and/or eye contact

The primary health hazards associated with cryogenic liquids are extreme cold and asphyxiation. Prolonged exposure of the skin or contact with cold surfaces can cause frostbite, which may cause the skin to appear waxy and yellow. Eyes can be damaged by short exposures that may not damage surrounding skin. Intense pain will occur when frozen tissue thaws. Prolonged breathing of extremely cold air may damage the lungs. Cold, heavy gas does not disperse readily and can accumulate near the floor, displacing air, asphyxiation and death can occur. Due to the significant expansion ratio of these materials (e.g., LN2 has a liquid-to-gas expansion ratio of 710 times), a small amount of spilled cryogenic liquid can displace a large amount of air, especially in relatively small rooms.

Chronic Exposure

NA





Hazardous Materials: Cryogenic Gas Safe Handling Guideline


First Aid

First aid measures will vary based on the individual chemicals hazard properties. In general, the following steps should be completed. Move victim to fresh air. Call 911. Apply artificial respiration if victim is not breathing. Remove and isolate contaminated clothing and shoes. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and quiet. Consult a physician immediately if exposures have occurred.

Exposure Limits

Exposure limits will vary based on individual chemical hazards, consult the manufacturers MSDS for established exposure limits. The primary risk is from oxygen deficiency.

Exposure Controls


Local exhaust ventilation is required. In some cases, gas detection may be required. Consult the individual chemical hazard properties to determine the proper engineering controls. Bulk tanks shall be sited in appropriate locations outside of the building. Smaller tanks and dewars should not be stored inside unless adequate ventilation and detection are present to prevent the development of an undetected asphyxiation hazard.


Personnel working with the materials must receive detailed training on the hazards, safe use, and emergency procedures.


Avoid contact with body parts. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids. Follow individual chemical’s MSDS recommendations for the appropriate PPE. In general, prevent skin/eye contact through the use of impervious gloves, clothing, boots, apron, and eye goggles or full face shield. In the event of a possible asphyxiation hazard, only self-contained breathing apparatus may be used for entry.

Disposal

Contact the Haas representative or the hazardous materials program manager for the return of empty, or damaged, cylinders or dewars to the supplier.

Medical Monitoring (if applicable)

NA

Emergency Response

In the event of a significant release that poses a threat to employees and/or the environment, immediately evacuate the area and notify the emergency operator (911). The Palo Alto Fire Department will respond. Then call Incident Notification (ext. 5555) and notify your supervisor.

Hazardous Materials: Crystalline Silica Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Crystalline silica

Synonyms

Silica, silicon dioxide


Silica, or silicon dioxide, is a naturally occurring mineral and its physical structure may exist in either crystal or amorphous forms. It is the crystal form of silica that poses the greatest health hazard to workers. The crystal form of silica is also called crystalline silica, and exists in several forms: quartz, cristobalite, tripoli, and tridymite. Quartz is the most common form of crystalline silica found in nature and in industrial use. Because crystalline silica is a major component of sand, granite, and other rock materials, it is common in the work environment. Occupational exposure to silica occurs in abrasive sand blasting, foundry work, stonecutting, rock drilling, quarry work, tunneling, and other construction related jobs.

Inhalation of silica can lead to silicosis, a debilitating lung disease. Silicosis creates inflammation and scar tissue formation in the lungs, reducing the body’s ability to extract oxygen from the lungs. As the disease progresses, pulmonary and cardiac impairment may occur to the point where oxygen must be supplied continuously to sustain life. Once silicosis has developed there is no cure for the disease; however, silicosis is preventable if one can reduce silica dust exposure.

Exposure Hazards

Likely Exposures at SLAC

Gravel and sand used in cement mixing often contains large amounts of crystalline silica. During construction activities, fine crystalline silica dust could be generated and become air borne, posing a hazard to workers and people in the vicinity.

At SLAC, silica dust exposure to employees mainly comes from construction-related activities such as Concrete structure drilling Abrasive polishing using silica sand Cement mixing Silica sand blasting Dry sweeping and other activities that generate a visible cloud of dust

Routes of Exposure

The primary route of exposure that is of concern is through inhalation.





Hazardous Materials: Crystalline Silica Safe Handling Guideline

Chronic Exposure

Chronic overexposure to silica dust results in the formation of fibrotic nodules and scarring around the trapped silica particles. This condition of the lung is called silicosis. If the nodules grow too large, breathing becomes difficult and death may result.

First Aid

As exposure to silica is a chronic exposure concern, there are no first aid requirements. Exposure of dust to the eyes can cause irritation, and the eyes can be flushed with water to clear them.

Exposure Limits Refer to the OSHA Table Z-3, “Mineral Dusts”, 29 CFR 1910.1000, Table Z-3

Exposure Controls


Industrial hygiene assessments should be conducted to include silica dust monitoring, hazard analysis and providing the results to exposed workers and their supervisors. Results of these assessments should include Recommendation of engineering and administrative controls to reduce silica dust

exposure Recommendation of appropriate and suitable respirators and other PPE for the job Offering hands-on practical training and quantitative fit tests for respirator use. If feasible, recommending non-silica material for abrasive blasting operations.

Engineering controls may include: attaching a dust control system to power tools; using a wet spray method if feasible to suppress dust during sand blasting, jack hammering or other construction activities; and when feasible, using a local exhaust ventilation system to remove dust from the work area.


Silica hazards and controls should be identified in pre-work hazard analysis forms prior to performing construction related activities. This applies to any work project that involves the job activities listed in the sections above. If the work includes airborne silica particles, contact the ES&H industrial hygienist at Ext. 4105 for assistance in minimizing exposure.

Silica exposure may also be minimized by reducing exposure time.

Warning signs will be posted if an area is designated by ES&H as a high silica dust area.


Eye: safety glasses or safety goggles

Chemical Name/Class

Ethane

Synonyms

Bimethyl, dimethyl, ethyl hydride, methylmethane


Incompatible with chlorine, dioxygenyl tetrafluoroborate, and oxidizing materials. Extremely flammable. Will be easily ignited by heat, sparks or flames. Will form explosive mixtures with air. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Containers may explode when heated. DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.

Exposure Hazards

Routes of Exposure

Inhalation, skin contact

Ethane is considered to be physiologically and toxicologically inert. At high concentrations, ethane acts primarily as a simple asphyxiant by displacing oxygen from the blood and air. Oxygen deprivation and asphyxiation symptoms include headache, dizziness, numbness of the extremities, sleepiness, mental confusion, poor judgment and coordination, memory loss and may eventually lead to unconsciousness and death. Skin contact with liquid ethane causes severe frostbite.

Chronic Exposure

NA

First Aid

If inhaled, move victim to fresh air. Call 911. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and quiet.

Exposure Limits ACGIH TLV: 1000 ppm (TWA)

Excursions in worker exposure levels may exceed three times the TLV-TWA for no more than a total of 30 minutes during a work day, and under no circumstances should they exceed 5 times the TLV-TWA, provided that the TLV-TWA is not exceeded.





Hazardous Materials: Ethane Safe Handling Guideline

Hazardous Materials: Flammable and Combustible Liquids Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Flammable and combustible liquids

Synonyms

Will vary depending upon specific chemicals


Liquids that pose a fire hazard are grouped as flammable and combustible according to their flashpoints. Generally speaking, flammable liquids will ignite and burn easily at normal working temperatures (i.e., flash points at or below 100ºF (38ºC). Combustible liquids usually burn at temperatures that are above normal working temperatures (i.e., must be preheated in order to ignite). At normal room temperatures, flammable liquids can give off enough vapor to form mixtures with air that present fire hazards. Spray mists of flammable and combustible liquids in air may burn at any temperature if an ignition source is present. The vapors from most flammable and combustible liquids are heavier than air, these vapors can settle and collect in low areas and present a hazard of flash back. Some flammable and combustible liquids are corrosive. Many undergo dangerous chemical reactions if they contact incompatible chemicals such as oxidizing materials, or if they are stored improperly.

Exposure Hazards

Routes of Exposure

The health hazards associated with flammable and combustible liquids will vary depending upon the individual chemical’s hazards, the manufacturers MSDS should be consulted for each chemical in use. Generally the hazards presented may include the following: Inhalation of flammable liquids can cause irritation to the respiratory passages,

nausea, headaches, muscle weakness, drowsiness, loss of coordination, disorientation, confusion, unconsciousness, and death.

Skin contact with flammable liquids can cause the skin’s oils to be removed, resulting in irritated, cracked, dry skin, rashes, and dermatitis.

Eye contact with flammable liquids can cause burning, irritation, and eye damage.

Chronic Exposure

Chronic exposure hazards associated with flammable and combustible will vary greatly and can range from damage to the lungs, liver, kidneys, heart and/or central nervous system may occur, cancer and reproductive effects are also possible. Consult the individual chemical’s MSDS for specific chronic hazards.

Hazardous Materials: Organic Peroxides Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Organic peroxides

Synonyms

None, will vary based on individual chemicals


Organic peroxides can be explosive, corrosive, and toxic and present extreme fire hazards. They are also strong oxidizing agents and combustible materials contaminated with most organic peroxides can catch fire very easily and burn very intensely. Many organic peroxides give off flammable vapors when decomposing. Because they combine both fuel (carbon) and oxygen in the same compound, some organic peroxides are dangerously reactive. They can decompose very rapidly or explosively if they are exposed to only slight heat, friction, mechanical shock, or contamination with incompatible materials.

Storage of some chemicals can form explosive organic peroxides spontaneously. Generally the types of chemicals that may form peroxides include aldehydes, ethers and unsaturated hydrocarbon compounds (allyl compounds, haloalkenes, dienes, monomeric vinyl compounds, vinylacetylenes, and unsaturated cyclic hydrocarbons like tetrahydronapthalene and dicyclopentadiene). If crystals are seen in containers, do not handle - these peroxides can be extremely shock sensitive and explosion is possible.

Exposure Hazards

Routes of Exposure


Many organic peroxides are toxic and can produce allergic response and eye damage. Individual chemical health hazards may vary greatly and it is very important that users consult the manufacturer’s MSDS to familiarize themselves with potential health hazards.

Chronic Exposure

Chronic exposures to organic peroxides will vary greatly and can range from liver and kidney damage to respiratory illnesses such as pneumonia. Consult the individual chemical’s MSDS for specific chronic hazards.

First Aid

First aid measures will vary based on the individual chemicals hazard properties. In all cases, always remove any contaminated clothing due to the fire hazard present. Consult a physician immediately if exposures have occurred.





Hazardous Materials: Organic Peroxides Safe Handling Guideline

Exposure Limits

Exposure limits will vary based on individual chemical hazards, consult the manufacturer’s MSDS for established exposure limits.

Exposure Controls


Local exhaust ventilation or breathing protection is required. Explosion proof electrical equipment and construction materials compatible with organic peroxides are required. Ensure all incompatible exhaust streams are segregated. Store all materials in appropriate containers. Secondary containment of all storage and use is required.

Organic peroxides should be stored in sealed, air-impermeable containers. In most cases, dark amber glass with a tight fitting cap is acceptable. Do not store organic peroxides in containers with loose fitting caps or ground-glass stoppers. Plastic containers are not recommended. Diethyl ether should be stored in steel containers, because the iron tends to neutralize peroxides.


Job hazard analysis and mitigation (JHAM) and procedures should be developed for the safe use and handling of organic peroxides in all applications. ESH can provide information and guidance. Ensure JHAMs and procedures comply with all manufacturers recommendations regarding storage conditions and time limits/chemical expiration dates. Personnel working with the materials must receive detailed training on the hazards, safe use, and emergency procedures.

Establish a regular inventory check to remove older chemicals from inventory, label new chemicals, and ensure each chemical is properly stored. Information on each label should include: date received, date opened, responsible person, and expiration date. If no expiration date is provided by the manufacturer, it should be recorded as six (6) months from the date received.


Avoid all contact with substances. Follow individual chemical’s MSDS recommendations for the appropriate PPE. In general, prevent skin/eye contact through the use of impervious gloves, clothing, boots, apron, and eye goggles or full face shield.

Avoid breathing dusts, mists or vapors. If the airborne concentration limits are exceeded and engineering controls are not feasible wear a NIOSH-approved self-contained breathing apparatus with full face-piece operated in the pressure demand or other positive pressure mode.

Disposal

Organic peroxides are generally regulated as hazardous waste. Containers and other materials that are contaminated with organic peroxides must also be treated as hazardous waste and handled in a safe manner due to the unusual stability issues related to organic peroxides. Contact the Waste Management Group for specific disposal requirements and procedures.


Medical monitoring will vary depending on the individual chemical hazards. Consult the MSDS or an Industrial Hygienist for the appropriate medical monitoring for the chemical of concern.

Emergency Response

In the event of a release that poses a threat to employees and/or the environment, immediately evacuate the area and notify the emergency operator (911). The Palo Alto


Hazardous Materials: Organic Peroxides Safe Handling Guideline


Fire Department will respond. Then call Incident Notification (ext. 5555) and notify your supervisor.

Hazardous Materials: Nitric Acid Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Nitric acid

Synonyms

Aqua fortis, engraver’s acid, hydrogen nitrate, red fuming nitric acid (RFNA), white fuming nitric acid (WFNA)


Incompatible with many organic materials, combustible materials, metallic powders, hydrogen sulfide, carbides, alcohols, reacts with water to produce heat, corrosive to metals. May generate hydrogen gas on contact with certain metals (e.g., aluminum). Not combustible but enhances combustion of other substances. May give off poisonous oxides of nitrogen & acid fumes when heated in fires. The substance decomposes on warming producing nitrogen oxides. The substance is a strong oxidant and reacts violently with combustible and reducing materials, e.g., turpentine, charcoal, alcohol. The substance is a strong acid, it reacts violently with bases. Reacts very violently with organic chemicals (e.g., acetone, acetic acid, acetic anhydride), causing fire and explosion hazard. Attacks some plastics. Reacts explosively with metallic powders, carbides, cyanides, sulfides, alkalies, and turpentine.

Exposure Hazards

Routes of Exposure

Inhalation may result in a burning sensation, cough, labored breathing, chemical pneumonia, unconsciousness, and death. Symptoms may be delayed. Skin contact may result in serious skin burns, pain, and yellow discoloration. Eye contact may result in redness, pain, and severe deep burns. Ingestion may result in abdominal pain, burning sensation and shock.

Chronic Exposure

Long-term exposure to concentrated vapors may cause erosion of teeth and lung damage. Long-term exposures seldom occur due to the corrosive properties of the acid.

First Aid

If exposed through inhalation, bring victim out into fresh air, keep in a half-upright position, do not allow to lay flat (fluid may accumulate in lungs), provide oxygen if needed. Artificial respiration may be needed. Provide immediate medical attention. If skin contact occurs, remove contaminated clothes. Flush skin with (cool or tepid) water or shower for 15 minutes. Provide medical attention. If eye contact occurs, flush with cool or tepid water for at least 15 minutes (remove contact lenses if easily possible).

Hazardous Materials: Mercury and Mercury Compounds Safe Handling Guideline Department: Industrial Hygiene and Information Management Program: Hazardous Materials Owner: Program Manager Authority: ES&H Manual, Chapter 40, Hazardous Materials1

Chemical Name/Class

Mercury and mercury compounds

Synonyms

Mercury metal, colloidal mercury, metallic mercury, quicksilver


Mercury is a silver liquid metal that vaporizes at temperatures as low as 10º F. Mercury vapor is colorless and odorless. If a mercury spill is not cleaned up promptly it may be ground into the floor, dispersing into extremely small particles with a large total surface area (6.4 ft2 for 1 ml as 10 micron spheres). From such large areas mercury may vaporize at a rate faster than the room’s ventilation can safely dilute it. The rate of mercury volatilization is directly related to temperature. A common occurrence is the breaking of thermometers in ovens due to bumping or raising the oven above the thermometer’s capacity. Additionally, the impact of mercury at high velocities or its release into high air velocity systems will also atomize mercury into extremely small particle sizes and large surface area.

Elemental mercury is incompatible with acetylene, aluminum, ammonia, azides, calcium, chlorates, chlorine dioxide, copper, copper alloys, ethylene oxide, halogens, iron, metal oxides, nitrates, oxygen, lithium, lead, nitromethane, rubidium, sodium carbide, sulfur, sulfuric acid, and others.

Exposure Hazards

Routes of Exposure


A pool of mercury exposed to the air can produce airborne concentrations greater than the permissible exposure limit of 0.05 mg/m3. Organo-alkyl mercury compounds are highly toxic and can be fatal on contact with skin (e.g., a Dartmouth chemistry professor died in 1997 from an exposure to dimethylmercury that penetrated through a latex glove). Elemental mercury can remain on the skin for many hours creating the potential for ingestion.

Chronic Exposure

Chronic poisoning can be caused by long-term exposure to low levels of mercury. Steady exposure can cause a slow buildup of mercury in the body that produces illness, personality changes, and eventual disability. Symptoms of chronic poisoning include tremors, mental disturbances such as insomnia, irritability and indecision, headache,





Hazardous Materials: Mercury and Mercury Compounds Safe Handling Guideline

fatigue, muscular weakness, stomach ache, excessive salivation, digestive disturbances, anorexia, weight loss, inability to absorb protein, and eye and skin irritation.

First Aid

Immediately seek emergency medical attention. Eye contact: irrigate immediately Skin contact: wash promptly with soap Breathing: oxygen administration and respiratory support Ingestion: medical attention immediately

Exposure Limits

Metallic Mercury Vapor NIOSH REL: TWA 0.05 mg/m3 (skin) Other: C 0.1 mg/m3 (skin) OSHA PEL: C 0.1 mg/m3 IDLH: 10 mg/m3 (as Hg)

Organo-alkyl Mercury Compounds NIOSH REL: TWA 0.01 mg/m3, ST 0.03 mg/m3 (skin) OSHA PEL: TWA 0.01 mg/m3 C 0.04 mg/m3 IDLH: 2 mg/m3 (as Hg)

Exposure Controls


The use of mercury is restricted. Use an alternative if one is available. For example: use alcohol thermometers instead of mercury ones; oil bubblers instead of mercury bubblers when possible; reducing agents other than mercury amalgams; etc. Avoid using mercury thermometers in ovens – if it breaks, this will be a significant hazmat clean up situation. When handling mercury use a glass, plastic, or steel tray to contain any spills that might occur. Glass or plastic vessels should have a secondary steel or plastic container around them in case the vessel fails.


Managers and supervisors must notify ES&H before beginning new processes involving mercury or mercury compounds. Plastic containers should be used to store mercury whenever possible. Label all equipment and vessels containing mercury. Close all containers of mercury when not in use. Store mercury in a secured area. Maintain a written inventory of mercury usage, location, and amounts.


Skin. Elemental mercury require nitrile, PVC, or latex gloves. Organo-alkyl mercury compounds require the use of silver shield, 4H, or other brand laminate-style gloves and outer gloves (heavy-duty nitrile or neoprene, with long cuffs).

Eye. Safety glasses or safety goggles.

Respiratory. Elemental mercury vapor: concentrations up to 0.5 mg/m3, a half-face air purifying respirator with a cartridge that provides protection for mercury vapor can be used. For concentrations between 0.5 and 2.5 mg/m3 a full face cartridge respirator may be used. Above that a self-contained breathing apparatus is required. Organo-alkyl mercury vapor: due to the high toxicity of organo-alkyl mercury compounds, a self-contained breathing apparatus is required if concentrations are in excess of the PEL.

Disposal

Dispose of mercury as hazardous waste. Do not combine it with “regular” organic or inorganic wastes. Never dispose of it down the sink.


Hazardous Materials: Mercury and Mercury Compounds Safe Handling Guideline


Contact the Waste Management Group for specific disposal requirements and procedures.


Medical Services will determine the need for biological monitoring or medical surveillance examinations of workers with potential mercury exposure based on an evaluation of the operation and workplace controls, as well as input received from ES&H.

Emergency Response

In the event of a release, immediately evacuate the area: Do not attempt to clean up spilled mercury. Immediately notify ES&H and Waste Management (extension 2399). Evacuate the area and prevent reentry.

If after business hours or if there has been an exposure call (911). The Palo Alto Fire Department will respond. Then call Incident Notification (ext. 5555) and notify your supervisor.
