3 3 The Workplace Hazardous Materials Information System is 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…

4 4 WHMIS has 3 Main Parts Labels – provide information about the hazards of the product Material Safety Data Sheets (MSDS) – provide further detailed information Education – how to use the information provided

5 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…

6 6 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.

7 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 – for more information regarding TDG: WHMIS Does Not Apply

8 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 WHMIS Does Not Apply

9 WHMIS labels and MSDS are still required for: Mixtures of radioactive nuclide(s) and a non-radioactive carrier material where: The carrier material is greater than 1.0 ml / 1 g The carrier material poses a carcinogenic, toxic, reactive, or infectious hazard WHMIS Applies for For more information regarding Radiation Safety:

10 Hazard Classes & Symbols There are 6 Hazard Classes
