WHMIS – THE RIGHT TO KNOW
Many hazardous materials are found in industry today. Exposures to these materials can result in harm or death.
Workers using these materials have the "right to know" what these materials are, how they can be harmed by them and what they can do to protect their health and safety
The WHMIS program was introduced to provide workers with this information
Introduction
WHMIS – BASIC AWARNENESS
An optional "test" is available for those wishing to demonstrate their knowledge of these basic concepts. A certificate identifying the participant, score and date is also available to document knowledge of the basic WHMIS fundamentals
This presentation has been designed to provide the participant with a BASIC OVERVIEW of the WHMIS program. It provides an "awareness" of the types of information that is legally required in the workplace.
This presentation is NOT designed to replace the employer's responsibility for providing proper instruction on ALL hazardous materials found in the workplace.

WHMIS -HISTORY
An NZ sheep farmer accidentally drank a selenium solution that damaged his internal organs
Sean Kells
Mark Smith
Later while spraying pesticides, Mark used a respirator with the wrong cartridges and damaged his lungs
As a 19-year old student, Sean was working at a factory pouring flammable materials from one container to another. A spark set off an explosion and Sean was burned to 90% of his body. He died the following day.
Over the years many people have been killed or seriously injured as a result of exposure to hazardous materials. A couple of examples are:
WHMIS -EFFECTS
Acute effects are those that are felt immediately after a large exposure to a hazardous material
Latency Period
Acute
Hazardous materials are those that can they can have harmful effects on the human body. These effects can be:
The latency period is the time between exposure and when the harmful effects are felt. The latency period could be months or years
ChronicChronic effects are those that are felt after a long-term exposure to low levels of a hazardous material
WHMIS -ROUTES OF ENTRY
Through the nose or mouthExamples are fumes or vapours breathed in
Absorption
Inhalation
Hazardous materials can enter the body in a number of ways. These "routes of entry" are:
Ingestion
Direct penetration of the skinExamples are needles and slivers
Through the mouthExamples are materials accidentally eaten or drunk
Through the skinExamples are solvents used to wash hands
Injection
WHMIS -3 GROUPS
LabourGovernment
Employees handling hazardous materials have the "right to know" what they are handling and how it can harm them. 3 groups got together and implemented the WHMIS program so that employees could receive this information. These 3 groups were:
Industry
WHMIS -3 COMPONENTS
2. MSDS
1. Labels
There are 3 main components of the WHMIS program. 3 ways in which information is provided to users of hazardous materials
3. Training
WHMIS -LABELS
WorkplaceLabel
SupplierLabel
Under the WHMIS program containers of hazardous materials are to have a proper label. There are two types of labels:
WHMIS -SUPPLIERSupplierLabel
Supplier labels are to be on containers of WHMIS-controlled products brought into the workplace. They are to have:
1. The name of the product
2. Risk phrases
3. Precautionary measures
4. First aid measures
5. Appropriate hazard symbols
6. Reference to MSDS
7. The name of the supplier
8. A dashed border
WHMIS -WORKPLACE
WorkplaceLabel
Workplace labels are required on containers into which WHMIS-controlled products have been poured. They are to have:
1. The name of the product
2. Handling instructions
3. Reference to MSDS
WHMIS – MSDSMaterial
A valid Material Safety Data Sheet is required for each WHMIS-controlled product in the workplace. The MSDS provides additional information on hazardous materials and is normally provided by the supplier of the product. An MSDS is required to have the following categories (not necessarily the exact words or order shown):
1. Product Identification2. Hazardous Ingredients
4. First aid measures5. Preventive Measures
6. Fire or Explosion Hazards7. Toxicological Properties8. Reactivity Data
SafetyData

9. Preparation Information

WHMIS – TERMS
The measure of the acidity or alkalinity of a materialRange is 0 to 14Less than 7 are acidsGreater than 7 are basesThe closer to 0 or 14 the more corrosive the material
LD50
:
LC50
:
pH:
The Lethal Dose of a material that when fed to test animals causes 50% of them to die (the lower the number, the more toxic the material)
The Lethal Concentration of a material in the air when breathed by test animals causes 50% of them to die (the lower the number, the more toxic the material)
The following are terms that may be found on an MSDS
WHMIS – TERMS
SpecificGravity:
If less than 1, indicates that a liquid will float on waterIf greater than 1, indicates that a liquid sinks in water
The following are terms that may be found on an MSDS
VapourDensity:
If less than 1, indicates that a vapour will rise in airIf greater than 1, indicates that a vapour sinks in air
TLV: The Threshold Limit ValueSets maximum concentrations of contaminants in airFor 8-hour day or40-hour work week
WHMIS – TERMS
FlashPoint:
The lowest temperature at which flammable vapours will burst into flame with a source of ignition
The following are terms that may be found on an MSDS
AutoIgnitionTemperature:
BoilingPoint:
The lowest temperature at which flammable vapours will spontaneously burst into flame
The highest temperature at which a liquid will turn into a solid
The lowest temperature at which a liquid will turn into a vapour
FreezingPoint:
WHMIS – TRAINING
The information contained on WHMIS labels
Workers who use hazardous materials or who may be exposed to them are to receive training so that they understand:
Proper procedures for storing, handling and using hazardous materials
Emergency procedures in the event of spills or escapes of hazardous materials
The information contained on an MSDS
Generic concepts as well as specific information on the particular hazardous materials used in the workplace
WHMIS – EMPLOYER RESPONSIBILITIES
Prepare an Inventory of all hazardous materials in the workplace(in conjunction with the Joint Health & Safety Committee)
Under the Occupational Health & Safety Act, the employer has certain responsibilities. Some of these are:
Not allow hazardous materials to be used unless:-they are properly labeled-there is a valid MSDS-worker training has taken place
Ensure that all hazardous materials are properly labeled
Ensure that there is a valid MSDS for all hazardous materials
WHMIS – CONTROLS
At theSource:
Elimination of the material if it is not requiredSubstitution with a less hazardous material (if available)Most effective form of control
Controls are required to reduce the amount of exposure of hazardous materials to employees. There are 3 main types of controls:
Along thePath:
At theWorker:
Often involves the use of ventilation to reduce exposureMay result in others being exposedLess effective than at the source
Involves the use of Personal Protective Equipment(gloves, goggles, respirators, etc.)May interfere with worker comfortLeast effective form of control
