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

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
