three components of whmis
Three Components of WHMIS
  • Labels on hazardous materials or their containers
  • MSDS or material safety data sheets which are technical bulletins providing more detailed information than the label
  • Worker education, providing instruction on hazards and safe work procedures

what do we know
What Do We Know?

2 of 2

Compressed Gas

(Class A):

  • Poses an explosion danger because the gas is under pressure
  • Container may explode if heated in a fire, or dropped

2003 16

what do we know1
What Do We Know?

2 of 2

Combustible and Flammable Material

(Class B):

  • Will burn and is therefore a potential fire hazard
  • May burn at relatively low temperatures; flammable materials catch fire at lower temperatures than combustible materials
  • May burst into flame spontaneously in air, or release a flammable gas on contact with water
  • May cause a fire when exposed to heat, sparks, or flames, or as a result of friction

Oxidizing Material

(Class C):

  • Poses a fire and/or explosion risk in the presence of flammable or combustible material
  • May react violently when it comes into contact with combustible materials such as fuels or wood
  • May burn skin and eyes upon contact

Poisonous and Infectious Material

(Class D, Division 1):

  • Is a potentially fatal poisonous substance
  • May be fatal or cause permanent damage if it is inhaled or swallowed or if it enters the body through skin contact
  • May burn eyes or skin upon contact

Poisonous and Infectious Material: Other Toxic Effects (Class D, Division 2):

  • Not immediately dangerous to health
  • May cause death or permanent damage as a result of repeated exposure over time
  • May be a sensitizer, which produces an allergy
  • May cause cancer, birth defects, or sterility

Poisonous and Infectious Material: Biohazardous, infectious material

(Class D, Division 3):

  • May cause a serious disease resulting in illness (AIDS, Hepatitis) or death
  • Can also include tetanus protection

Corrosive Material

(Class E):

  • Causes severe eye and skin irritation upon contact
  • Causes severe tissue damage with prolonged contact
  • Often produces vapor or fumes that may be harmful if inhaled

What Do We Know?

2 of 2

Dangerously Reactive Material

(Class F):

  • Is very unstable
  • May react with water to release a toxic or flammable gas
  • May explode as a result of shock, friction or an increase in temperature
  • May explode if heated when in a closed container
  • Undergoes vigorous polymerization

worker education
Worker Education

1 of 2

Anyone working with or nearby controlled products must be trained in hazard information and procedures regarding:

  • Safe use
  • Storage
  • Handling
  • Disposal
  • Emergency procedures

WHMIS Responsibilities

Suppliers, employers and employees each have a role to play in making WHMIS work.

summary
Summary

1 of 2

  • Labels
  • MSDS
  • Worker Education

WHMIS has three components:

  • Compressed Gas
  • Flammable
  • Oxidizers
  • Poisons
  • Corrosives
  • Reactive

WHMIS is a hazard class driven system
