Workplace Hazardous MaterialsInformation System
The provincial WHMIS legislation does not apply to federal workplaces such as banks, post offices and airports. Canada Labour Code and Canada Occupational Safety and Health Regulations implement WHMIS in federal workplaces.
Products under the Federal Acts:
Flammable & Combustible Material
Class D Poisonous & Infectious Material
Serious Toxic Effects
E.g. styrene, hydrogen cyanide
Effects (carcinogen, irritant,
sensitizer) E.g. ammonia, asbestos
cause disease in humans
E.g. Hepatits B
Dangerously Reactive Material
Eight (8) pieces of information in English & French:
a. Product Identifier (common/chemical name)
b. Hazard Symbol(s)
c. Risk Phrase(s)
d. First Aid Measures
e. Supplier Identifier (name, address, etc.)
f. Reference to MSDS
g. Precautionary Measures
h. Border – must be distinctive & different from background of container

Nine or more categories of information: (MSDS handout)
Product Identification and Use
The product identifier, use, manufacturer’s name, address, and the PIN number (product identification number).
CAS or chemical abstract services, LD50 is lethal dosage which is commonly used for solids and liquids and is the weight of a substance which, if given all at once, is expected to cause the death of 50% of a test animal population, LC50 is lethal concentration, refers to the quantity of gases or vapours and is the concentration of a substance in air which administered over a specified period, is expected to cause the death of 50% of a test animal population.
State of the product - gas, solid, liquid, the appearance, colour, odour threshold, vapour pressure, vapour density, evaporation rate, boiling point, freezing point pH, specific gravity, coefficient of water/oil distribution.
Fire and Explosion Data
Conditions under which material may be flammable (ignite and burn readily), means of extinction, explosion data (explode as a result of being dropped or subjected to impact), sensitivity to static discharge, safe handling methods, flash point, auto ignition temperature, Upper Explosive Limit/Lower Explosive Limit.
Conditions under which the product is chemically unstable such as heating, burning, exposure to sunlight, will list the substance or class of substance with which the product is incompatible, or decomposition products.
Explains the health effects which may result from over exposure, route of entry into the body, inhalation, absorption, ingestion, puncture/injection, acute or chronic, occupational exposure limits like TWA Time Weighted Average Values, Short Term Exposure Limits, Ceiling, evidence of carcinogen, sensitizing capabilities.
How to avoid potential hazards associated with exposure to the material, - controls, equipment and procedures (i.e. type of eye protection/hand/face), waste disposal, handling and storage procedures, shipping information.
First Aid Measures
Provides information on safe evacuation procedures and the immediate treatment of persons overexposed to the material.
Preparation Data of MSDS
Who prepared the MSDS, telephone number and date of MSDS. MSDS remain valid for 3 years from the date shown, unless new information becomes available before then, at which point the supplier must update the MSDS within 90 days.
Health & Safety Program, Working Alone Program, Lab Safety Program, Ergonomic Program, Hazardous Waste Management Program, Biological Safety Program, Laser Safety Program, Field Trips & Electives Planning and Approval Program, Fire Safety Program, etc.
In what section of an MSDS could I find how the WHMIS controlled product enters the body?
A) Physical data
B) Fire and explosion hazard
C) Hazardous Ingredients
D) Toxicological Properties
On a workplace label the safe handling procedures provide information on reducing your potential risk of harm from working with this hazardous material.
True or False?
WHMIS supplier labels must include a product identifier, supplier identifier, MSDS reference, hazard symbols, risk phrases, precautionary measures and first aid measures in both English and French.
True or False?
The Material Safety Data Sheet (MSDS) for the corresponding WHMIS controlled product needs to be read and understood before using the product?
True or False?
