WHMIS (Workplace Hazardous Materials Information System) uses classifications to group chemicals with similar properties or hazards. The Controlled Products Regulations specifies the criteria used to place materials within each classification. There are six (6) classes although several classes have divisions or subdivisions. The Workplace Hazardous Materials Information System (WHMIS) is Canada's national hazard communication standard. The key elements of the system are hazard classification, cautionary labelling of containers, the provision of (material) safety data sheets ((M)SDSs) and worker education and training programs. Partially exempt products, which are labelled under federal legislation other than WHMIS, can be sold without WHMIS labels and MSDSs. However, when these products are used in the workplace, provincial OSH regulations require worker education and training, and workplace labels must be applied if they are not in their original containers. WHMIS 2015 applies to two major groups of hazards: physical, and health. Each hazard group includes hazard classes that have specific hazardous properties. Physical hazards group : based on the physical or chemical properties of the product – such as flammability, reactivity, or corrosivity to metals. WHMIS controlled products are divided into a) 12 classes identified by letters b) 6 classes identified by letters c) 12 classes identified by numbers d) 6 classes identified by numbers. b) 6 classes identified by letters. The classification criterion for flammable gas is a) critical temperature b) the "lower flammable limit", LFL This booklet will explain the basics of Workplace Hazardous Materials Information System (WHMIS), including: Overview—background to WHMIS development, key elements, and key participants Classification—hazard classes and symbols; exempt products Labels—supplier labels, workplace labels, and other identifiers What is WHMIS. WHMIS which represents (Workplace Hazardous Materials Information System) is an hazardous product regulation system which helps identify the hazards of products like chemical and infectious agents. WHMIS groups products with similar properties or hazards into classes. WHMIS (Workplace Hazardous Materials Information System) uses classifications to group chemicals with similar properties or hazards. The Controlled Products Regulations specifies the criteria used to place materials within each classification. There are six (6) classes although several classes have divisions or subdivisions. WHMIS 1988 - WHMIS Classes, Divisions and Subdivisions and Corresponding Hazard Symbols Class A - Compressed Gases Class B - Flammable and Combustible Materials WHMIS – Six Classes WHMIS covers six classes of controlled products, which are divided into eight symbols. This classification is the . foundation of WHMIS. Class A: Compressed Gas . Class D2: Poisonous and infectious materials causing other toxic effects . Class D3. Class B
