Safety Symbols at Home and Work HHPS and WHMIS Safety Symbols at Home and Work

HHPS – Household Hazardous Product Symbols Hazardous Household Product Symbols are found: On products that the public can buy in the store Only in the USA and Canada (Other countries have their own set of symbols)

HHPS: Household Hazardous Product Symbols These symbols are made up of a picture and a frame: The picture tells you the type of danger. The frame tells you if it is the chemical inside the container that is hazardous if it is the container that is hazardous. Dangerous contents in container Dangerous container                                                                                                                      Poison       Flammable     Explosive        Corrosive  

HHPS: Household Hazardous Product Symbols Before October 1, 2001 the old regulations required three different frames (Yield sign, diamond and stop sigh) to indicate the degree of hazard. Now, only two frames are used to distinguish between the contents of the product and the container itself.

WHMIS – Workplace Hazardous Materials Information System WHMIS has 8 symbols: See your handouts!

CLASS A: COMPRESSED GAS This class includes compressed gases, dissolved gases, and gases liquefied by compression or refrigeration. CLASS B: FLAMMABLE AND COMBUSTIBLE MATERIAL This class includes solids, liquids, and gases capable of catching fire in the presence of a spark or open flame under normal working conditions. CLASS C: OXIDIZING MATERIAL These materials increase the risk of fire if they come in contact with flammable or combustible materials.

CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 1: Materials Causing Immediate and Serious Toxic Effects These materials can cause death or immediate injury when a person is exposed to small amounts. CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 2: Materials Causing Other Toxic EFFECTS These materials can cause life-threatening and serious long-term health problems as well as less severe but immediate reactions in a person who is repeatedly exposed to small amounts. CLASS D: POISONOUS AND INFECTIOUS MATERIAL Division 3: Biohazardous Infectious MATERIAL These materials contain an organism that has been shown to cause disease or to be a probable cause of disease in persons or animals.
