What are the WHMIS 2015 Pictograms?

Hazard pictograms form part of the international Globally Harmonized System of Classification and Labelling of Chemicals (GHS). These pictograms are graphic images that immediately show the user of a hazardous product what type of hazard is present. 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 "square set on one of its points" border. More information can be found on the Government of Canada website.
