-was developed for people buying and using product around the home.
MSDS• Material Safety Data Sheets• Must be provided with all
chemicals.• Indicates information about
the possible hazards.
Compressed Glass Flammable and Combustible material
Oxidizing Material
Poisonous and Infectious Material Causing Immediate and Serious Toxic Effects
Poisonous and Infectious Material Causing other toxic effects
Biohazardous Infectious Material
Corrosive Material Dangerously Reactive Material
WHMIS: The Categories Categories Definition Examples
A Compressed Glass Product is under pressure. (Dangerous as it may leak, explode, rocket, or cause frostbite)
Oxygen and propane
B Flammable and Combustible Material
Product is combustible or flammable (Flammable
means that the material will burn or catch on fire easily at normal temperatures (below 37.8 degrees C or 100 deg F). Combustible materials must usually be heated before they will catch on fire at temperatures above normal (between 37.8 and 93.3 deg C or 100 and 200 deg F).
PropaneAcetoneKeroseneMagnesiumSodium
Categories Definition Examples
C Oxidizing Material
May cause or help the combustion of another material by providing more oxygen to the fire.
Hydrogen peroxide
Nitric acid
sodium chloride
D1 Poisonous and Infectious Material Causing Immediate and Serious Toxic Effects
Serious health effects such as burns, loss of consciousness, coma or death within just minutes or hours.
carbon monoxide

D2 Poisonous and Infectious Material Causing other toxic effects
Their effects are not always quick, or if the effects are immediate, they are only temporary. May cause cancer, allergies, harm to baby etc..… sensitization which has resulted from small exposures over a long period of time (chronic effects).
• asbestos fibers• mercury• lead
D3 Biohazardous Infectious Material
*Living organisms.* the toxins can cause disease in people or animals

can cause severe burns to skin and other human tissues and can eat away at clothes and other materials including metal
* Ammonia gas* Hydrochloric acid * Javex* Chlorine
