L 11 Class A: Compressed Gases Risks poses an explosion hazard because contents of cylinder are under pressure container may explode if heated in a fire container may explode if dropped
WHMIS - Your right to know...L 13 Class B: Flammable & Combustible Materials potential fire hazard may ignite spontaneously may be a material which will release flammable products if allowed to degrade or when exposed to water Risks L 21
L 15 Class C: Oxidizing Materials can cause skin or eye burns increased risk of fire and/or explosion risk in the presence of flammable or combustible material can cause other materials to react or break down Risks
L 21 Class D - Division 3: Biohazardous Infectious Risks biological materials which can cause a disease or have the same effects as the disease materials which could contain organisms which are infectious materials which could contain biological toxins or allergenic sensitizers
L 23 Class E: Corrosive Materials eye and skin irritation on exposure severe burns/tissue damage possible lung damage if inhaled may cause blindness if eyes contacted environmental damage from fumes Risks

Hazards Precautions Emergency Response How will you prepare to eliminate or reduce risks of danger? If an accident does occur, how will you respond? What dangers might this chemical impose?
Do your homework!! Look up the hazards on the MSDS.
WHMIS - Your right to know...L 38 Controlling Hazards by taking Precautions….
What Do I Do If......? A chemical contacts my skin? A chemical contacts my eyes? I break glassware? I spill water? I spill acid? Hot liquid overflows while on my hotplate? My test tube contents fizz and bubble over the top? I notice a frayed electrical cord? My lab partner(s) is not following lab rules?
