WHMIS TRAINING Workplace Hazard Material Information System

LEARNING TARGET Be able to identify WHMIS symbols Be able to determine the hazards associated with various products

WHAT IS WHMIS?  Overview  Classification

WHMIS CLASSIFICATIONS There are 8 Hazard Symbols. Hazard symbols are used to identify the specific hazard associated with the controlled product. Will it blow up? Is it poisonous? Will it burn my skin? Etc.

THE WHMIS SYMBOLS

We are now going to take a closer look at the 8 hazard symbols.

Compressed Gas It is important to know that these containers cannot be stored or placed near heat or dropped as this may cause the container to explode. Examples of Compressed Gases would be: Propane, Oxygen and Acetylene.

Flammable and Combustible Material Class B is made up of solids, liquids and gases that are capable of catching on fire by means of spark or open flame in normal working conditions. Examples include: Butane, Gasoline or Acetone (paint thinner).

Oxidizing Material The main hazard with these products is the risk of fire when they come into contact with flammable or combustible materials. Examples include hydrogen peroxide or compressed oxygen.

Poisonous & Infectious materials causing immediate and serious toxic effects. These materials in small amounts can cause immediate injuries or death to a person. Examples include: Hydrogen Sulphide or Sodium Cyanide.

Materials causing other toxic effects. These materials can cause serious long-term health problems and severe immediate reactions to the material over long periods of time when being exposed to small amounts repeatedly.

Biohazardous Infectious Material Biohazardous Infectious materials contain dangerous micro-organisms that can be extremely harmful to humans. Examples include bodily fluids, bacteria, THE ZOMBIE VIRUS!!!

Corrosive Material Corrosive materials are acids and caustics that can burn and destroy skin or eat through metals. Examples Include: Hydrochloric acid sodium hydroxide

Dangerously Reactive Material When exposed to temperature, pressure or shock these material may explode. They also carry a risk of self- reacting or releasing poisonous gases when exposed to water. Examples Include: Group 1 elements are dangerously reactive with water; combining bleach, drain cleaner, and ammonia would produce chlorine gas (mustard gas)
