Introduction to whmis

Introduction to Whmis

WHMIS is Canada-wide legislation, dealing with controlled products in the workplace.

*A controlledproduct is ‘any product, material or substance included in any one of the classes listed in the Hazardous Products Act (HPA).’

2003 3


Whmis is designed to solve the problem of

WHMIS is Designed to Solve the Problem of:

  • Unlabelled materials in the workplace

  • Inadequate or contradictory information being given to employers/workers regarding identification, hazardous properties and precautions to be taken with hazardous materials used in the workplace

2003 4


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

Labels

Labels

Two Types:

  • Supplier labels (developed and provided by the supplier)

  • Workplace labels (developed and used in the workplace)

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

  • examples include: compressed air, carbon dioxide, propane, oxygen, ethylene oxide, and welding gases

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

  • Common examples include: propane, butane, acetylene, ethanol, acetone, turpentine, toluene, kerosene, Stoddard solvent, spray paints and varnish.

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

  • Oxidizers can also be in the form of gases (oxygen, ozone), liquids (nitric acid, perchloric acid solutions) and solids (potassium permanganate, sodium chlorite).

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

  • Examples of some D-1 materials include carbon monoxide, sodium cyanide, sulphuric acid, toluene-2,4-diisocyanate (TDI), and acrylonitrile.

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

  • Examples include: asbestos fibres, mercury, acetone, benzene, quartz silica (crystalline), lead and cadmium.

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

  • Examples of biohazardous infectious materials include the AIDS/HIV virus, Hepatitis B and salmonella.

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

  • Common corrosives include acids such as sulphuric and nitric acids, bases such as ammonium hydroxide and caustic soda and other materials such as ammonia gas, chlorine, and nitrogen dioxide.

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

  • Examples of these products are ethyl acrylate, vinyl chloride, ethylene oxide, picric acid and anhydrous aluminum chloride.

2003 32


Supplier responsibilities

Supplier Responsibilities

Supplier responsibilities are found under the Hazardous Products Act

(Federal Bill C-07)
