WHMIS Training WHMIS is a Canada-wide hazard communication standard for protecting the health and safety of workers who handle hazardous chemicals. WHMIS training is a legal requirement for employees who may be exposed to hazardous materials. WHMIS (Workplace Hazardous Material Information System) has been updated to include GHS (Globally Harmonized System). It was amended in 2015. You may hear the term WHMIS, WHMIS with GHS, or simply WHMIS 2015 all interchangeably, but they all refer to the new and improved, updated WHMIS program in Canada. New: Visit the Hazardous Substance Assessment page to see classification information for select chemicals. 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. The Workplace Hazardous Materials Information System (WHMIS) has aligned with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). GHS is a worldwide system. Its goal is to have a common set of rules for classifying hazardous products, common rules for labels, and a standard format for safety data sheets (SDSs).

WHMIS Symbols 2020 with meanings [New Updated] Symbols (pictograms) are used in WHMIS to visually represent the type of hazard a hazardous substance presents. This will also help full for WHMIS Test 2020.

WHMIS Pictograms/ Symbols

Workplace Hazardous Materials Information System (WHMIS) was introduced in Canada in 1988 so that workers could receive information about the hazardous products they may use.

The WHMIS Pictograms/ Symbols are graphic images that immediately show you what type of hazard a hazardous product presents. With a quick glance, you can see, for example, that the product is flammable, or if it might be a health hazard.

Most pictograms have a distinctive red, diamond-shaped border. Inside this border is a symbol that represents the potential hazard (fire, health hazard, corrosive, etc.). Together, the symbol and the border are referred to as a pictogram. Pictograms are assigned to specific hazard classes or categories.

WHMIS Symbols are used in WHMIS to visually represent the type of hazard a hazardous substance presents. You will see both pictograms and class symbols in the workplace and it’s important to understand both.
