Determine hazardous chemicals in work areas
• Consult the list of hazardous chemicals
• Chemical manufacturers supply hazard information
1a
Determine hazardous chemicals in work areas
• Chemicals at this facility
• Chemicals in your work area
1b
Health hazards
• Acutely toxic• Chronically toxic• Carcinogenic• Mutagenic
• Teratogenic• Sensitizing agent• Corrosive• Irritant
2a
Health hazards cause Health hazards cause health effects upon exposurehealth effects upon exposure
Physical hazards include any chemical that is:
• Combustible liquid• Compressed gas• Explosive• Flammable• Organic peroxide
• Oxidizer• Pyrophoric• Unstable (reactive)• Water-reactive
2b
Dispensing and storage techniques
• Know how to properly handle hazardous chemicals
• Check for MSDS information
4a
Dispensing and storage techniques
• Take the following precautions:• wear recommended safety
equipment• work in well-ventilated areas• store and dispense of
chemicals properly• avoid creating sparks near
hazardous chemicals
4b
Detecting hazardous chemicals in work areas
• Know how to detect whether a chemical has been spilled, or is otherwise present in the environment in an uncontrolled manner
5a
First aid procedures
• Read MSDSs for first aid information
• Have emergency eyewash stations and showers available
6a
Emergency eyewash stations
• If a chemical splashes into eyes:• get to a flushing station immediately• hold eyes open with your
fingers - lift your eyelids• look directly into stream of
water• flush eyes for 15 minutes• get medical attention
7b
Material safety data sheets
• Primary tool for getting detailed chemical information
• Must be readily available
9a
Material safety data sheets include:
• Chemical identity
• Physical and chemical characteristics
• Physical and health hazards
• Primary routes of entry
9b
Material safety data sheets include:
• PEL, TLV, other exposure limits
• Whether it is a carcinogen
• Precautions for safe handling/use
• Recommended engineering controls
9c
Material safety data sheets include:
• Emergency first aid procedures
• Date of preparation
• Name, address, phone number of manufacturer, importer, responsible party
9d
Material safety data sheets
• MSDSs may contain recommendations from ANSI
• MSDSs also provide information regarding:• signs and symptoms of
exposure• personal protective
equipment• spill and leak clean-up• labeling information
9e
Report the need for MSDSs
• Check with supervisor if MSDS appears to be missing
• Chemical suppliers provide MSDSs
10a
Report the need for MSDSs
• MSDSs must be part of the facility’s HazCom program
• Your employer makes sure they are kept up to date
10b
Labeling requirements
• Labels warn of potential dangers
• Labels are not intended to be the sole source of information
• Labels serve as an immediate warning
11a
Labeling requirements
• Labels must be keyed to MSDSs
• Labels must contain:• the identity of the hazardous chemical• appropriate hazard warnings• the name, address of the
chemical manufacturer, importer, other responsible party
11b
Labeling requirements
• Ensure that labels do not come off, become smudged or unreadable
• For hard-to-label containers, use:• signs or placards• process sheets, or batch tickets
11c
Labeling requirements
• Be able to quickly identify the general hazard of any material:• NFPA system identifies:
• health hazards• flammability
hazards• reactivity hazards• special hazards
11d
Labeling requirements
• Be able to quickly identify the general hazard of any material:• HMIS system identifies
• health hazards• flammability hazards• physical hazards
