I. Purpose

This Chemical Hygiene Plan (CHP) sets forth policies, procedures, equipment, personal protective equipment and work practices that are capable of protecting employees and students from the health hazards presented by hazardous chemicals used in laboratories. This Plan is intended to meet the requirements of 8 CCR 5191 and 29 CFR 1910.1450, Occupational Exposure to Hazardous Chemicals in Laboratories, a copy of which is found by clicking on the links.

II. Scope

This CHP applies to our Physical and Life Science Laboratories where employees work with substances in containers that are easily and safely manipulated by one person. The objective of this program is to provide guidance to all laboratory personnel who use chemicals, so that they can perform their work safely. Laboratory Employees -- Each individual working in a laboratory should be informed about hazards associated with that laboratory and the specific work going on there. This includes all faculty, laboratory staff and student workers. Support Personnel -- Storeroom, janitorial, maintenance, and delivery personnel may be exposed to potential physical and chemical hazards from work carried out in the laboratory. They must be informed about the risks involved and trained how to avoid potential hazards.

III. Responsibilities

A. Chemical Hygiene Officer

The Vice President of Business Administration has been appointed as the Chemical Hygiene Officer until a Risk Manager or equivalent is hired by the College. The Chemical Hygiene Officer is responsible for the Chemical Hygiene Program throughout the college and provides continued direction for the Chemical Hygiene Program. The Chemical Hygiene Officer shall:

● Work with administrators, faculty and laboratory staff to develop and implement appropriate chemical hygiene policies and practices;

● Monitor procurement and use of chemicals in the lab, determining that laboratory facilities and training levels are adequate for chemicals in use;

● Perform regular, formal chemical hygiene and housekeeping inspections that include inspections of emergency equipment;

● Maintain a current chemical inventory of chemicals present within the College property;

● Review and improve the Chemical Hygiene Plan on, at a minimum, an annual basis;

● Maintain overall responsibility for the safe operation of the Physical Science and Life Science Laboratories;

● Ensure that employees know and follow chemical hygiene rules;

● Determine the proper level of personal protective equipment; ensure that such protective equipment is available and in working order;

4

● Ensure that the appropriate training has been provided to employees;

C. Faculty Faculty teaching laboratory courses in chemistry and in the life sciences will review student laboratory safety policies with each class. Students will sign documentation certifying that they have received a copy of the relevant safety rules and agree to abide by them. Copies of the rules for SMC laboratory courses are available in Appendix A of this document. In addition, faculty must provide information to students regarding lab procedures, appropriate PPE, and other safety information specific to each experiment.

IV. Standard Operating Procedures for Laboratory Chemicals

A. Chemical Procurement

The decision to procure a new chemical shall be made by the appropriate Department Chair who will ensure a commitment to safe handling and use of the chemical from initial receipt to ultimate disposal. Santa Monica College policy is to continually and aggressively evaluate current inventory and properly dispose of unnecessary materials. Requests for procurement of new chemicals (i.e. those not currently included in a department’s chemical inventory – this does not apply to re-orders of substances already in use) shall be submitted to the appropriate Department Chair for approval. An SMC Requisition Form shall be used for this purpose (refer to Purchasing Department’s website for further information). The appropriate Chair, prior to procurement of a new chemical, shall identify information on proper handling, storage and disposal. If, upon investigation, the chemical is extremely hazardous (e.g., mutagenic, carcinogenic, teratogenic), extremely flammable and/or explosive, or difficult to dispose of, the relevant Department Chair shall ensure that an

5

appropriate standard operating procedure be developed and implemented for the safe use of that substance. Chemicals used in the laboratory shall be those that are appropriate for the ventilation system. All chemicals must be received in either the Chemistry Stockroom or the Microbiology/Physiology Preparation Room. Personnel who receive chemical shipments shall be knowledgeable of the proper procedures for receipt. Chemical containers shall not be accepted without accompanying labels, safety data sheets (SDS), and packaging in accordance with District policy and/or state and Federal guidelines. If a chemical is shipped without the SDS, the document must be downloaded upon receipt. SDS sheets are available at the websites given below. All chemical shipments should be dated when received and opened.

Fisher Scientific website http://www.fishersci.com/us/en/catalog/search/sdshome.html Sigma Aldrich website (search for product and click SDS in search results) http://sigmaaldrich.com/

All science department computers should have a shortcut to this Chemical Hygiene Plan on the desktop.

B. Chemical Storage Received chemicals shall be moved within one working day of receipt to the designated chemical storage area by lab technicians. Large glass containers shall either remain in their original shipping container or be placed in carrying containers (e.g., rubber "boots") during transportation. The storage area shall be well illuminated, with storage maintained at or below eye level. Flammables will be stowed in the designated flammable storage cabinets in lab prep areas. Chemicals must be segregated by hazard classification and compatibility in a well-identified area, with good general exhaust ventilation. Mineral acids should be segregated from flammable and combustible materials. Separation is defined by NFPA 49 as storage within the same fire area but separated by as much space as practicable or by intervening storage from incompatible materials. Acid resistant trays shall be placed under bottles of mineral acids.

Nitric acid will be stored in an acid cabinet. Acid sensitive materials, such as cyanides and sulfides, shall be separated from acids and protected from contact with acids and water. Highly toxic chemicals or other chemicals whose containers have been compromised shall be stored in unbreakable secondary containers.

6

The storage area shall NOT be used as a preparation or repackaging area. The storage area shall be accessible during normal working hours. The storage area is under the control of the Life and Physical Science Departments. Stored chemicals shall be examined at least annually by the appropriate Laboratory Technician for container integrity and/or deterioration. The inspection should determine whether any corrosion, deterioration, or damage has occurred to the storage facility as a result of leaking chemicals, and be annually documented. The appropriate Laboratory Technician shall conduct periodic inventories of chemicals outside the storage area. Unneeded items shall be properly discarded or returned to the storage area. SUGGESTED CHEMICAL STORAGE PATTERN Storage of laboratory chemicals presents an ongoing safety hazard for college science departments. Many chemicals are incompatible with each other. The common method of storing these products in alphabetical order sometimes results in incompatible shelved materials. For example, storing strong oxidizing materials next to organic chemicals can present a hazard. A possible solution is to separate chemicals into their organic and inorganic families and then to further divide the materials into related and compatible families. Below is a list of compatible families. INORGANIC

1. Metals, Hydrides

2. Acetates, Halides, Iodides, Sulfates, Sulfites, Halogens, Thiosulfates, Phosphates

3. Amides, Nitrates (except Ammonium Nitrate), Nitrites, Azides

4. Hydroxides, Oxides, Silicates, Carbonates

5. Sulfides, Selenides, Phosphides, Carbides, Nitrides

6. Bromates, Perchlorates, Perchloric Acid, Chlorites, Hypochlorites, Peroxides, Hydrogen Peroxide

7. Arsenates, Cyanides, Cyanates

8. Borates, Chromates, Manganates, Permanganates

9. Acids (except Nitric). Store acids in a designated cabinet. *Nitric Acid is isolated and stored by itself.

10. Sulfur, Phosphorus, Arsenic, Phosphorus Pentoxide

ORGANIC

1. Acids, Anhydrides, Peracids

2. Alcohols, Glycols, Amines, Amides, Imines, Imides

3. Hydrocarbons, Esters, Aldehydes

4. Esters, Ketones, Ketenes, Halogenated Hydrocarbons, Ethylene Oxide

5. Epoxy Compounds, Isocyanates

7

6. Peroxides, Hydroperoxides, Azides

7. Sulfides, Polysulfides, Sulfoxides, Nitriles

8. Phenols, Cresols

ADDITIONAL STORAGE SUGGESTIONS

1. No floor chemical storage.

2. No top shelf chemical storage.

3. No reactive liquid chemicals stored above eye level.

4. Shelf assemblies are firmly secured to walls. Avoid island shelf assemblies.

5. Provide anti-roll-off lips on all shelves.

6. Ideally shelving assemblies would be of wood construction.

7. Avoid metal, adjustable shelf supports and clips. Better to use fixed, wooden supports.

8. Store acids in dedicated acid cabinet(s). Store nitric acid in that same cabinet ONLY if isolated from other acids. Store both inorganic and some organic acids in the acid cabinet.

9. Store flammables in a dedicated and ventilated flammables cabinet.

10. Store severe poisons in a dedicated poisons cabinet.

11. Segregate known or suspect carcinogens from other chemicals.

12. If you store volatile materials (ether, hydrocarbons, etc. in a refrigerator, the refrigerator must be explosion-proof. The thermostat switch or light switch in a standard refrigerator may spark and ignite volatile vapors in the refrigerator.)

13. 2,4-dinitrophenylhydrazine solid will be kept wet for storage purposes to avoid explosion hazard.

14. Except for bases and other chemicals that react with glass, storage in glass is recommended.

15. Lower shelving is recommended for storage, when feasible.

C. Chemical Handling

Each laboratory employee (with training, education, and resources provided by supervision) shall develop work habits consistent with requirements of the Santa Monica College CHP to minimize personal and coworker potential exposure to chemicals. Based on the realization that all chemicals inherently present hazards in certain conditions, exposure to all chemicals shall be minimized. General precautions that shall be followed for the handling and use of all chemicals are:

1. The amount of chemicals at the lab bench shall be as small as practical.

2. Skin contact with hazardous chemicals shall be avoided at all times.

3. Employees shall wash all areas of exposed skin prior to leaving the laboratory. Soap is provided at each sink.

4. Mouth suction is prohibited for pipetting or starting a siphon.

5. Eating, drinking, smoking, chewing gum, or application of cosmetics in the laboratory is prohibited.

8

6. Storage of food or beverages is not allowed in storage areas or refrigerators used for laboratory operations.

7. All chemicals and equipment shall be properly labeled, in accordance with Santa Monica College CHP guidelines.

14. Specific precautions based on the toxicological characteristics of individual chemicals shall be implemented as deemed necessary by the CHP.

15. There will be no use of highly pyrophoric chemicals, or compounds that react violently with air or water vapor, such as organolithium compounds or lithium aluminum hydride. Other less reactive but similar chemicals, such as Grignard reagents, sodium, or other hydride compounds should be used only after consultation with SOPs and in accordance with the CHP. Procurement of such chemicals should only happen with direct approval of the department chair(s) and the Chemical Hygiene Officer.

D. Laboratory Equipment and Glassware

Each employee shall keep the work area clean and uncluttered. At the completion of each workday or operation, the work area shall be thoroughly cleaned and all equipment cleaned and stowed. In addition, the following procedures shall apply to the use of laboratory equipment:

1. All laboratory equipment shall be used only for its intended purpose.

2. All glassware will be handled and stored with care to minimize breakage; all broken glassware will be immediately disposed of in the broken glass container.

3. All evacuated glass apparatus shall be shielded to contain chemicals and glass fragments should implosion occur. Heavy-walled filtration flasks connected to aspirators or house vacuum lines are excepted.

4. Labels shall be attached to all chemical containers, identifying the contents and related hazards.

5. Waste receptacles shall be clearly labeled.

6. All laboratory equipment shall be inspected on a periodic basis and replaced or repaired as necessary.

7. Engineering controls and safety equipment in the laboratory shall be utilized and inspected in accordance with guidelines established in the CHP.

9. The appropriate Laboratory Technician shall visually inspect fire extinguishers monthly. A log of the date of the last visual inspection shall be posted by each extinguisher. Regular maintenance of fire extinguishers is the responsibility of SMC’s Facilities Department.

E. Personal Protective Equipment

Safety goggles meeting ANSI Z87.1 are required for employees and visitors to the Chemistry laboratories or Laboratory Preparation areas and will be worn at all times when chemicals are being used or manipulated in the laboratory. The wearing of contact lenses in the laboratory is strongly discouraged. Chemical goggles and/or a full-face shield shall be worn during chemical transfer and handling operations as procedures dictate. Chemical and flame resistant lab coats should be worn in the laboratory. Lab coats shall be removed immediately upon discovery of significant contamination. Appropriate chemical-resistant gloves shall be worn at all times when there exists the potential for skin contact with hazardous chemicals. Used or contaminated gloves are to be disposed of in the special glove disposal containers in each lab. Contaminated gloves must not be worn outside of the laboratory. Thermal resistant gloves shall be worn for operations involving the handling of heated materials and exothermic reaction vessels. Thermal resistant gloves shall be non-asbestos and shall be replaced when damaged or deteriorated. Respirator usage shall comply with OSHA Respiratory Protection Standard, 29 CFR 1910.134, and the Santa Monica College's Respiratory Protection Program.

F. Personal Work Practices

Department Chairs and supervisors must ensure that each employee knows and follows laboratory-specific rules and procedures established by this plan. Faculty must ensure that enrolled students receive appropriate instruction in laboratory safety polices. Appendix A of this document provides copies of the basic lab safety rules for Physical and Life Science laboratory courses. For information on more specific hazards, the appropriate Department Chair should be contacted. All employees shall remain vigilant to unsafe practices and conditions in the laboratory and shall immediately report such practices and/or conditions to the Department Chair. The Chair must PROMPTLY correct unsafe practices or conditions. Long hair or loose-fitting clothing shall be confined close to the body to avoid contact with chemicals or being caught in moving machine/equipment parts. Avoid unnecessary exposure to hazardous chemicals by any route.

10

Do not smell or taste any laboratory chemicals. Encourage safe work practices in coworkers by setting the proper example. Horseplay is strictly forbidden. Seek information and advice from knowledgeable persons regarding Standards and Codes about hazards present in the laboratory and plan operations, equipment, and protective measures accordingly. Use engineering controls (fume hoods, safety shields and general ventilation) in accordance with CHP procedures. Follow fume hood sash markings for proper ventilation. Inspect personal protective equipment prior to use, and wear appropriate protective equipment as procedures dictate and when necessary to avoid exposure.

G. Labeling

All containers in the laboratory shall be labeled. This includes both secondary chemical containers and waste containers. The labels shall be informative and durable, and at a minimum, will identify contents, source, start date of acquisition or accumulation, and indication of hazard that is in accordance with the Globally Harmonized System of labeling (GHS) and the OSHA Hazard Communication System (HCS), which are provided by the manufacturer. Portable containers shall be labeled by the individual using the container. Exemptions for labeling requirements shall be made for chemical transfers from a labeled container into a container that is intended only for the immediate use of the employee who performed the transfer.

V. Criteria for Implementation of Control Measures

A. When to use fume hoods:

Hoods must be used for experiments that produce toxic, offensive, or flammable materials. Some student experiments will require the use of hoods. Processes that have potential for generating hazardous airborne chemical concentrations must be carried out within a fume hood.

B. When to use personal protective equipment:

Eye Protection - Safety goggles meeting ANSI Z87.1 must be worn by all personnel in the laboratory whenever hazardous chemicals are in use. NO EXCEPTIONS. Gloves - Gloves should be worn to protect the skin from chemical and physical (e.g. heat, cold) exposures. Used or contaminated gloves are to be disposed of in the special glove disposal containers in each lab. Contaminated gloves must not be worn outside of the laboratory. Thermal resistant gloves shall be worn for operations involving the handling of heated materials and exothermic reaction vessels. Thermal resistant gloves shall be non-asbestos and shall be replaced when damaged or deteriorated. Laboratory Coats – Flame-resistant, knee-length laboratory coats are to be worn by all employees while working with laboratory chemicals.

11

Respirators - Respiratory protection may be necessary to maintain chemical exposure below OSHA's PEL. Respirators will be provided, if necessary.

C. When to institute special work practices:

The Department Chairs must approve special work practices. If particularly hazardous chemicals are to be used (e.g. carcinogens, reproductive toxins, teratogens, or acutely toxic chemicals), standard operating procedures for the use of these substances must be developed and followed.

VI. Fume Hood Management

A. Frequency and type of monitoring - all local exhaust hoods used for primary containment control will be monitored for adequate airflow annually. The survey will be completed with a calibrated velometer and results must include marking of the safe sash opening level. An approved environmental firm will provide monitoring and results will be documented and kept in SMC’s Risk Management office.

B. Acceptable operating range - Minimum face velocities of at least 100 linear fpm, with a minimum of 70 fpm at any point, must be maintained for each hood. If the face velocity does not meet a MEI recommended minimum of 100 linear fpm, maintenance personnel must be contacted to repair or upgrade the hood.

C. Maintenance schedule - Maintenance of local exhausts or fume hoods will be completed on an "as needed" basis, or annually, whichever comes first.

VII. Employee Information and Training

A. Information

1. A copy of the California Code of Regulations, Title 8, Section 5191: Occupational Exposure to Hazardous Chemicals in Laboratories is available at http://www.dir.ca.gov/title8/5191.html.

2. The THRESHOLD LIMIT VALUES published by the American Conference of

Governmental Industrial Hygienists can be found in the material safety data sheets. Recommended exposure limits for other hazardous chemicals, information on signs and symptoms associated with exposures to hazardous chemicals, can be located in material safety data sheets. These sheets are available from the Laboratory Technicians or can be found online by searching for the name of the substance and SDS. Below are two recommended resources where SDS sheets may be found:

12

3. A list of OSHA health hazard definitions and lists of select carcinogens, reproductive toxins, and high acute toxicity materials can be found on safety data sheets.

B. Training

1. Employees will be provided with training to ensure that they are apprised of the hazards of chemicals present in their work area. Such training will be provided at the time of an employee's initial assignment to a work area where hazardous chemicals are present and prior to assignments involving new exposure situations. Refresher training will be provided annually.

2. Employee training will include:

● Methods and observations that may be used to detect the presence or release of a hazardous chemical.

● The physical and health hazards of chemicals in the work area.

● The measures employees can take to protect themselves from these hazards.

● The applicable details of the Chemical Hygiene Plan.

3. Students will receive safety training in conjunction with the course curriculum, as provided by the instructor. Laboratory safety rules for each laboratory course are provided in Appendix A of this document.

4. Training documentation will be managed by the District. Copies of training documentation should be forwarded to Risk Management.

VIII. Required Approvals

Certain laboratory procedures, which present serious health hazards upon exposure, require prior approval by either the Physical or Life Science Department Chair before work may commence. For Santa Monica College, prior approval is required for handling carcinogens, teratogens and mutagens.

IX. Medical Consultation and Examination

A. An employee who works with hazardous chemicals and subsequently:

● Develops symptoms associated with a hazardous chemical to which the employee may have been exposed in the laboratory

● Works where exposure monitoring reveals an exposure level routinely above the OSHA action level or, in the absence of a designated action level, exposure above the Cal OSHA Permissible Exposure Limit (PEL), (as published at https://www.dir.ca.gov/title8/5155table_ac1.html) for

16

OSHA regulated substances for which there are medical monitoring and medical surveillance requirements. Chemicals used at the college that fall within this category are:

○ Asbestos

○ Inorganic Arsenic

○ Lead or Lead Compounds

○ Benzene

○ Cotton Dust

○ Formaldehyde

● Or is exposed to a hazardous chemical during a spill, leak, or explosion or other occurrence resulting in exposure

is entitled to medical attention including an examination and follow-up exams as deemed necessary by the physician chosen by the employee.

An examination is provided without cost to the employee, without loss of pay, and conducted at a reasonable time and place.

B. Procedures to secure medical consultation and examination are as follows:

1. Seek immediate medical care at Student Health Services

2. Report exposure to CHO, Risk Manager, and Campus Police

3. The following information will be provided to the physician.

a) Identity of hazardous chemical.

b) Description of conditions under which exposure occurred.

c) Description of signs and symptoms employee is experiencing

d) Copy of SDS.

4. A written opinion from the physician shall be provided to the employer including:

a. Recommendation for further medical follow-up.

b. Results of medical exam and tests.

c. Any medical condition revealed during the exam that places the employee at increased risk.

d. A statement that the employee has been informed by the physician of the results of the exam and any medical condition that may require further treatment or examination.

X. Additional Protection with Handling Particularly Hazardous Substances

A. Work with selected carcinogens, reproductive toxins and substances that have a high degree of

acute toxicity may require additional employee protection. Specific consideration will be given to:

● Establishment of a designated area

● Use of containment devices such as fume hoods or glove boxes

● Procedures for safe removal of contaminated waste

17

● Procedures for handling spills of these reagents

● And decontamination procedures.

At present, no particularly hazardous chemicals are used, however some carcinogens are stored in Chemistry and Biology. (i.e. methylene chloride for some organic reactions, biological specimens preserved in formaldehyde, etc.).

XI. Emergency Response/Chemical Spills

All employees should be familiar with the College Emergency Preparedness/Hazardous Materials http://www.smc.edu/StudentServices/EmergencyPreparedness/Pages/Emergency-Preparedness.aspx A. When spills of hazardous chemicals occur within the Laboratory, the following procedures

are followed to prevent injury or property loss:

1. Provide any first aid (if necessary) to affected individuals. Liberally use eyewash station and/or safety shower to flush affected areas for AT LEAST 15 minutes. A large exposure to the body merits ambulatory service.

2. Notify Supervisor of spill. If spill is large enough to affect health or safety of people outside the immediate workspace, or if it is extremely hazardous, the Campus Police must be notified, who will in turn notify other agencies, as needed.

3. Evacuate the area.

4. Always refer to SDS for special precautions or spill cleanup requirements.

5. If spilled materials exhibit flammability, eliminate ignition sources such as hot plates, Bunsen burners, etc., if this can be done safely.

6. Avoid all contact with spilled material. If necessary, use protective gloves, gown, goggles, and/or respirator.

7. Obtain supplies from Chemical Spill Clean-Up Kit (located in Chemistry Stockroom and/or Biology Prep. Rooms). NOTE –only clean up a spill if you have received the proper level of training in order to clean up a routine, small quantity spill. However, if you are uncomfortable, do not proceed with cleaning up the spill.

8. Neutralize acids and bases.

9. Contain collected materials and label container with name of contents and also as Hazardous Waste.

B. Liquid Spills

1. Confine spill to as small an area as practical.

2. For small quantities of acids or bases, use the neutralizing agent from the chemical spill clean-up kit. An absorbent material specially prepared for acid/base spills may also be used.

3. For small quantities of other materials, such as organic solvents, utilize an absorbent material to clean-up spill. Examples of absorbent materials are vermiculite, dry sand, paper towels, etc.

18

4. For large quantities of inorganic acids and bases, flush with large amounts of water, preferably toward a containment area. *CAUTION must be taken not to add too much water to create a flood that may react with water-reactive materials and cause spattering and additional personnel exposure.

5. If possible, with small manageable spills, utilize spilled containment material (kitty litter, sand, or booms) found in the emergency spill kits located throughout the Science Departments. Large quantity spills will be handled by professional hazardous waste personnel or the fire department.

6. Carefully pick up and decontaminate any bottles, broken glass, and/or other containers. Decontaminate over the bucket or pail to collect contaminated wash.

7. Avoid using any shop vacuum that is not rated for chemical clean up. A potential exists for atomizing hazardous wastes and creating a potential human inhalation exposure.

8. If the spill is extremely volatile (high vapor pressure), allow the spill to evaporate and exhaust out the laboratory exhaust (e.g., fume hood).

9. Properly contain, label, store and/or dispose of collected hazardous waste. (See waste disposal section for methods).

C. Solid Spills

Sweep solid spill of low toxicity into a designated, easily decontaminated, dust pan and place in a labeled container for disposal.

D. Additional Spills Mercury - Clean up with a mercury spill clean-up kit. Collect elemental mercury in a sealed container to prevent exposure to mercury vapors. In the event of large spills or spills that render some mercury unavailable for clean up (e.g. mercury in floor cracks or beneath lab benches), an airborne evaluation of mercury vapor content may be required.

E. Compressed Gas Cylinders Any compressed gas cylinders used in science laboratories must have caps and be secured with two chains, top third and bottom third, at all times when in use and stored. In addition, all cylinders must be properly labeled. Regulators must not be left attached to unused cylinders for extended periods of time. Oxygen cylinders must be at least 20 feet away from combustibles, or be behind a fire wall.

F. Incident Report An incident investigation should take place after each spill and/or accident. The Incident Report should be completed by campus police and forwarded to the Chemical Hygiene Officer and Risk Management.

XII. Review And Update

This Chemical Hygiene Plan will be reviewed and updated annually.

Chemistry Laboratory Safety Rules

Personal Protective Equipment (PPE) and Safe Attire

1. Wear chemical safety goggles (ANSI Z87.1) and a knee length (41-42 inch) laboratory coat at all times while in the laboratory when anyone is conducting experiments. Regular, white lab coats are sufficient for Chem 9, 10, 11, 12, and 31; but blue, flame resistant Arc Rating ATPV 7.7cal/cm2 coats are required for Chem 21 and 24.

2. Wear closed shoes at all times while in the laboratory.

3. Wear nitrile gloves when directed to do so by your instructor and/or lab manual.

4. Confine long hair when in the laboratory so that it will not catch on fire or come into contact with chemicals.

Behavioral Rules for Safety

5. Do not enter the laboratory until your lab instructor is present.

6. Do not eat, drink, chew gum or smoke in the laboratory at any time. Keep all food and drinks sealed and in your backpack or purse.

7. Consider all chemicals to be hazardous unless instructed otherwise.

8. Do not taste anything in the chemistry laboratory.

9. Smell chemicals carefully and only when instructed to do so. Waft odors towards your nose rather than sniffing directly.

10. Do not use flammable liquids near open flames. Most organic liquids are flammable. Diethyl ether is especially dangerous.

11. When heating substances in a test tube, never point the mouth of the test tube at yourself or at anyone else. It may erupt like a geyser.

12. Do not force glass tubing or thermometers into rubber stoppers. The tubing or thermometer may break and cut you badly. Consult with your laboratory instructor for assistance.

13. Use caution when handling Bunsen burners, hot plates, and glassware or other equipment that has been heated. Burns are the most common laboratory injury so treat all equipment as if it were hot during experiments that involve heating.

14. Work with dangerous or volatile chemicals in a fume hood as directed by your instructor and/or lab manual.

15. Do not perform unauthorized experiments. If you see someone else doing something you think may be dangerous, tell him or her to stop and/or report the incident to your lab instructor. If another student tells you to stop doing something because it is unsafe, stop as directed. Consult your lab instructor if there is a problem or difference of opinion.

Handling Accidents

16. Notify your lab instructor immediately if you have an accident, spill, or are injured in any way.

17. If chemicals come in contact with your skin or eyes, wash with water for at least 15 minutes.

18. Know where to find and how to use the eyewash stations in the lab. It is not recommended to wear contact lenses in the laboratory since chemicals splashed in the eye may get under the lens therefore be difficult to

21

rinse. If a splash occurs while you are wearing contact lenses, they must be safely removed as quickly as possible.

19. Know where to find and how to use the safety shower in the front of the room.

20. Clean up spilled chemicals immediately. Consult your laboratory instructor if you are not sure what to do.

21. Solid sodium bicarbonate (baking soda) is available in the laboratories in containers located by the sinks. Use this to neutralize acid spills before wiping them up. Similarly, solid citric acid solution is available in containers by the sinks and should be used to neutralize base spills before wiping them up. A saturated solution of sodium bicarbonate is also available by the sinks and can be used to wipe dried acid or base residue off of lab benches as needed. However, if acid or base spills on your skin, don't waste time looking for these neutralizing substances. Rinse with water immediately for at least 15 minutes.

Proper Waste Disposal

22. Separate waste as follows:

• Waste chemicals should be disposed of as directed by your lab instructor. Most chemicals are NOT to be thrown down the sink. Special waste receptacles will be provided for these chemicals. Waste chemicals must be sorted by kind, not just mixed with other, different waste chemicals. Read waste container labels carefully. Notify your instructor when a waste bottle is nearly full. Do not overfill waste bottles.

• Broken glass is to be disposed of in the cardboard boxes labeled "Broken Glass Only" located near the doors to the lab. A dustpan and broom are located in each lab to assist you in cleaning up broken glass. Do not put broken glass in the regular trash, and do not put anything except broken glass in the broken glass containers!

• Gloves used in lab are to be disposed of in the containers labeled “Used Gloves Only” located next to the sinks in each lab.

• Other trash that is not glass and is not contaminated by hazardous chemicals should be placed in the large waste baskets near the front of the lab room.

Other Information You Should Know

23. The effects of chemical agents used in this course on human pregnancy are unknown. Pregnant women are advised to consult their physician before taking this course.

24. The Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65) requires that the Governor revise and publish annually the list of chemicals known to the state to cause cancer or reproductive toxicity. You may be exposed to one or more of these chemicals during this course. See your lab instructor for a list of these chemicals. You may also obtain a list from http://www.oehha.ca.gov/prop65.html.

25. Material Safety Data Sheets (MSDS) are available for all the chemicals used in this course. These sheets give information about the chemical, physical, and physiological properties of chemical substances. See your instructor for information about accessing these sheets. A shortcut to MSDS websites is available on each laboratory computer. They can also be found by entering the name of the chemical and MSDS into Google or any other search engine.

26. Each laboratory experiment involves its own specific hazards. Be sure to read your laboratory procedure carefully before arriving for lab, and take note of all safety precautions. You are responsible for the information provided in the laboratory procedure. You must also arrive on time for all laboratory sessions so you will be present to hear the safety information provided by your lab instructor. For the safety of all students in the class, students who arrive late to lab will not be allowed to perform the lab experiment that day.

Earthquake – duck or drop down to the floor; take cover under a sturdy desk or other piece of furniture; stay under cover until shaking stops and then evacuate (move away from the building); avoid glass windows and doors and objects that could fall. Explosion in Building – Take cover, contact Campus police, and evacuate if requested. Active Shooter - Try to remain calm and call the College Police at 310-434-4300 (or Ext. 4300 on campus phones) or dial 911 as soon as possible. In addition:

• Quickly move students and staff to a secure location. Stay away from windows.

• Close and lock all doors to offices and classrooms, turn off the lights, close blinds and hide.

• If your door cannot be locked from the inside, stack desk, tables, and chairs to form a barricade.

• Have everyone get down on the floor, or up against a solid interior wall, and shelter in place.

• Turn off cell phones or lower ring tone. Place cell phone to vibrate if possible.

• If there is no possibility of escape or hiding and only as a last resort should you make an attempt to negotiate with or overpower the assailant(s).

• Remain in place until told by an officer that is safe to leave. Power Blackout – Call Maintenance if working hours; if not call or deliver a message to Campus Police; secure experiments and equipment that may present a danger if electrical power is off or if a danger may be created by the return of power at a later time; turn off all electrical equipment, but leave room lights on; evacuate if needed. Evacuation – do if alarm sounds and/or upon notification by Campus Police or other authority; lock doors if possible; evacuate by route on “Evacuation Plan and Emergency Procedures”; do not use elevators; proceed to designated meeting spot away from building and stay there at least until it is determined that everyone is present; do not return to building until told to do so by a College Official. Illness or Injury – Call Campus Police (310) 434-4300 (or Ext. 4300 on campus phones). They are trained in first aid and will call Health Services if needed. For minor cuts, scrapes, students may be sent to Health Services with another person during business hours. If person refuses treatment this must be documented by Campus Police. Faculty and staff teaching classes and working in labs are not required to provide first aid. First aid kits are available in each laboratory for the use of first responders. People with Disabilities – identify people in advance; determine if your multi-story building has an Area of Evacuation Assistance; in the event of an emergency ask the person before you attempt to help them and ask how they want to be helped.

It can also result in the removal from class on the day of the incident and one subsequent class session. In addition, violation of the rules may result in a referral to the Office of Student Judicial Affairs for disciplinary action.

Although we use organisms that are not usually pathogenic, the instructors want students to develop appropriate techniques and safeguards against the day when they will be dealing with infectious materials. Therefore we perform as if we are in a clinical laboratory.

1. The Safe Drinking Water and Toxic Enforcement Act of 1986 requires that the Governor revise and publish at least once per year the list of chemicals known to the state to cause cancer or reproductive toxicity. You may be exposed to one or more of these chemicals during this course. Please see your instructor for a list of these chemicals.

2. The effects on human pregnancy of chemical agents used in this course are unknown, and a pregnant woman is advised to consult her physician before taking this course. Safety data sheets are available upon request. As contact with dyes used in staining may have potential teratogenic effects, a pregnant woman should avoid staining procedures as directed by her physician.

3. DO NOT EAT, DRINK, OR SMOKE IN THE LABORATORY. Keep fingers, pencils, gum, and other objects out of your mouth. Open

cuts, lesions, and the like should be covered with a band-aid, tape (gauze as appropriate), or gloves, when handling viable organisms.

4. Please be respectful of one another and the materials used in the microbiology lab. This includes not crowding one another for resources, careful use and care of microscopes, replacing prepared slides in their original boxes and other materials in the appropriate containers, and ensuring everyone’s safety by using proper aseptic and disposal practices.

5. Wear a flame resistant lab coat or other protective clothing and wear closed-toe shoes while working in the lab (Gram stains have an affinity for your best clothing). Avoid wearing garments with loose, hanging sleeves. They are a fire hazard. Similarly, confine long hair. Lab coats must cover the knees and should be long sleeved. A flame resistant lab coat is required.

6. Scrub down your desktop with the lab disinfectant on a paper towel at the beginning and end of each lab period.

7. Wash your hands with warm water and soap at the beginning and end of each lab period.

9. Label properly all inoculated media to be placed in incubators: name, date, section, name of organism, as directed by your instructor.

10. Always handle test tubes by the tube, not the top. Place test tubes in supportive containers at all times; use a test tube rack, beaker, or can. Circular test supports are to be used only in a double boiler, not for transport of test tubes. Never lay a test tube directly on a desk or cart. Test tubes roll off and spill.

11. Pipette fillers will be supplied for pipetting liquids. Do not pipette anything by mouth at any time. Discard all pipettes into proper receptacles.

12. Discard all used materials into proper containers. a. Test tubes to be used again will be sterilized before use. Place test tubes in designated racks as directed by your

instructor. b. Place commercially prepared slides back in their original boxes; clean them first by removing immersion oil with alcohol-

moistened lens tissue. c. Place used slides you have prepared in containers of disinfectant. Be sure the disinfectant covers the slides. Place swabs

in beakers of disinfectant. Do not overfill the containers. d. Place Petri dishes in the appropriate red Biohazard container. e. Discard stained gloves in the regular trash; discard contaminated gloves in the red Biohazard bucket as directed by your

instructor. 13. Discard broken glass into the appropriate Broken Glass container: Use the broken GLASS container for large items such as beakers,

and the SHARPS container for small items such as broken stained slides. Place only broken glass in the broken glass containers—do NOT place used paper towels, used but unbroken slides, or other materials in the broken glass container.

a. If a test tube containing bacteria breaks, notify the instructor. Use the dustpan and brush to pick up broken glass; do not pick up broken glass with a gloved or naked hand.

b. If a thermometer breaks, notify the instructor so any mercury can be collected safely. 14. Check to see that gas jets are off, except when flame is needed. Conserve fuel. The handle is OFF when perpendicular to the line.

15. All materials, cultures, and equipment must remain in the lab at all times. Do not take cultures, test tubes, or other materials from the lab.

16. Notify the instructor immediately of any injury, accident, or spill of bacteria. If you get an irritating chemical in your eye or on your skin you may be escorted to the eyewash station or the safety shower in the lab.

17. If a culture is spattered or spilled, first notify the instructor, then disinfect by covering with paper towels saturated with disinfectant. Leave in place for 10 minutes before cleanup. Place disinfected paper towels in the trash.

18. Photography, videos, and recordings can only be taken with instructor consent. They may not be given, sold, or published in print or online without the written consent of the instructor, and can only be used for the purposes of the class.
