“What Safety Errors Are Being Made?”
Overview for Today WHMIS HHPS
WHMIS stands for: Workplace Hazardous Materials Information System
WHMIS SYMBOLS WHMIS symbols were developed to standardize the labeling of dangerous materials used in all workplaces, including schools
COMPRESSED GAS product held under pressure do NOT puncture or store it near a heat source examples: propane canisters oxygen tanks helium tanks
FLAMMABLE/COMBUSTIBLE MATERIAL products that will burn or catch fire easily keep away from flames examples: acetone magnesium sodium
OXIDIZING MATERIAL products that promote the combustion (burning) of another material examples: hydrogen peroxide potassium permanganate
POISONOUS MATERIALS CAUSING OTHER TOXIC EFFECTS products whose health effects generally appear over time following one or several exposures examples: Asbestos Lead mercury
POISONOUS MATERIALS CAUSING IMMEDIATE SERIOUS TOXIC EFFECTS products that can cause harmful health effects, including death examples: carbon monoxide chlorine gas
BIOHAZARDOUS INFECTIOUS MATERIAL living organisms or their toxins can cause diseases in people or animals examples: medical waste sewage decaying matter
CORROSIVE MATERIALS products that can corrode metal surfaces or cause burns to skin examples: bleach toilet bowl cleaners sulphuric Acid
DANGEROUSLY REACTIVE MATERIALS products that can be health or safety hazards under certain conditions (high temperature, reaction with water or air) examples: hydrogen cyanide TNT
HHP symbols HHPS stands for Hazardous Household Product Symbols found on virtually all potentially dangerous household products indicates both the type of danger and the degree of risk
HHP SYMBOLS
Hazardous Household Product Symbols EXPLOSIVE Explodes or gives off deadly vapours. CORROSIVE Eats or wears away other materials. FLAMMABLE Ignites if exposed to heat or sparks. POISONOUS May cause sickness or death if swallowed.
