Workplace Hazardous Materials Information Systems

Canadian Legislation Ensures ready access to information on how

to work safely with chemical Workshops, offices, laboratories, clinical

setting Concerned with “controlled products” Criteria of both health and safety risks

Consumer products-Why? Cosmetics Explosives Food & Drugs Hazardous waste Pesticides Radioactive materials

Supplier◦ Provide a label for products that

Classify products Label products with a WHMIS label Prepare and provide customer’s Material Safety Data

Sheet Update the MSDS at least every three years

Train employees who work with chemical in WHMIS

Ensure safe work practices Ensure a workplace label is on all containers Ensure access to MSDS’s

Participate in training Follow prescribed work practices Wear required protective equipment

1. Compressed Gas◦ Stored under pressure◦ Oxygen

2. Flammable & Combustible Materials3. Oxidizing Materials-laboratories4. Poisonous & Infectious Materials

◦ Immediate and serious toxic effects◦ Other toxic effects

Compressed Gas• Gas at normal temperature and pressure• Packaged under pressure• Compressed air, O2, hydrogen, nitrogen

Flammable and Combustible Materials• Ignite and continue to burn in air• Gases, aerosols, liquids and solids• Solvents, cleaning material

Oxidizing Materials• Materials that release O2 or other oxidizing

substances and contribute to the combustion of other flammable materials

• Chlorine, nitrogen dioxide, hydrogen peroxide

Materials causing Immediate and Serious Toxic Effects

• Extremely toxic• Cause severe damage in single overexposure• cyanide

Materials causing other Toxic effects• Poses threat to our health through long term

exposure• Suspected carcinogen, mutagenicity, sensitization,

embryotoxicity, reproductive toxicity

Biohazardous Infectious Material• Presents the risk of biological or viral infection on contact• Biomedical waste containers for syringes, needles and

sharps• Linen and material contaminated with bodily fluids

Corrosive Material• Attacks metals and other substances• Fumes can cause permanent damage to human tissues

& organs• Strong acids, ammonia, fluorine

Dangerously Reactive Material• React violently under certain conditions• React violently with water
