A Canada-wide system designed to give employers and workers information about hazardous materials used in the workplace.
WHMIS standards are coordinated between both Federal and Provincial governments.
Manitoba Workplace Safety and Health Act and Regulations sets the WHMIS requirements.
WHMIS is…WHMIS is…

WHMIS has 3 Main PartsWHMIS has 3 Main Parts
Labels – provide information about the hazards of the product
Material Safety Data Sheets (MSDS) – provide further detailed information about the hazards associated with the product
Education – how to use the information provided in the MSDS and on the Label
Identify 6 Classes of Controlled Products
Understand the Main Hazards associated with each class
Recognize and understand the two types of WHMIS labels
Understand how to use Material Safety Data Sheets
The GOAL is…The GOAL is…

A Controlled Product is…A Controlled Product is…
Any substance or material which meets any of the criteria for inclusion in one or more of the six WHMIS Hazard Classes as defined in the Federal Controlled Product Regulation.
Under WHMIS , there is no comprehensive list of controlled products but only a list of hazard criteria.
When WHMIS does not apply there may be another Act or regulation that does.
WHMIS does not apply to controlled products that are: Wood or a product made of wood Tobacco or a product made of tobacco A manufactured item that will not release chemicals Products transported under the Transportation of
Dangerous Goods Act
WHMIS Does Not ApplyWHMIS Does Not Apply
WHMIS does not apply to products covered by:
Explosives Act Food and Drugs Act Pest Control Products Act
Certain products in the Hazardous Products Act Nuclear Safety and Control Act

Provide detailed information on the hazards of a controlled product An important element for developing safe work procedures and
control measures Must be provided by the supplier, or If you have created a product,
you must prepare a MSDS Risk Group 2 and higher biological agents also require a MSDS or a
Pathogen Safety Data Sheet (PSDS)
Material Safety Data Sheets (MSDS)Material Safety Data Sheets (MSDS)
MSDS’s must be replaced every 3 yearsAll MSDS must be kept for a minimum of 30 years

Information regarding the LD50 and LC50 (the amount of a chemical that is expected to kill 50% of a test animal population within a specified time) will also be given. The lower the value the greater the poisoning potential.
MSDSMSDS

Reactivity DataProvides information regarding stability, self-reactivity, hazardous decomposition products, and conditions to avoid when using the product.
Toxicological PropertiesIdentifies how the substance can enter the body and the possible health effects from short term (acute) exposures such as irritation, sensitization; and long-term (chronic) such as liver or kidney damage, sensitization, cancer, or reproductive effects. Known exposure limits will also be given.
MSDSMSDS
Information ProvidedInformation Provided
Preventative MeasuresProvides preventive measures you can take to protect yourself from exposure including: extra ventilation, personal protective equipment (PPE), safe use, handling, storage, disposal, transport, and spill control.
Preparation informationIndicated who was responsible for preparation and date of preparation of MSDS. It is 3 years from this date when the MSDS needs to be renewed.
Information may be labeled as Trade Secret if a claim has been filed. The information is released to medical professionals in case of emergency.

Every year the School Division coordinates a hazardous waste pick up with Miller Environmental.
Hazardous waste pick up occurs every June. Hazardous waste labels and Miller Environmental Hazardous
Waste Inventory sheets are available on the PTSD website. Science teachers should incorporate waste disposal into lab
procedures or experiments Reminder: NO disposal of Hazardous Waste is permitted
down the drain (unless it has been neutralized and pH verified) or regular trash can.
Remember that your end point is someone’s starting pointRefer to the PTSD Workplace S&H webpage for details
Hazardous Waste Disposal ProceduresHazardous Waste Disposal Procedures
If a spill occurs that poses an immediate risk to people, or if someone is injured – it is an EMERGENCY
Minor spills should be cleaned up by trained staff Spills must never be cleaned up by untrained staff Under no circumstance shall caretakers be instructed to clean up any
lab spills The best time to learn about and practice cleaning up a spill is before it
happens – read the MSDS S&H Officer is also available to assist with the cleanup of spills beyond
the capabilities of available staff
Information on spills cleanup can be found on the PTSD Workplace S&H website

As part of the Manitoba Workplace Safety and Health Act and Regulations, an inventory of chemicals is required at the Division every year.
The Division provides WellNet as a general database for all chemicals used in the Division. It can be accessed from the PTSD Workplace Safety & Health website.
