WHMIS class C refers to which type of material?

The designation of WHMIS class C pertains specifically to flammable and combustible liquids. In the context of the Workplace Hazardous Materials Information System (WHMIS), class C includes substances that can ignite and burn easily when exposed to an ignition source.

Flammable liquids have flash points below 37.8 degrees Celsius (100 degrees Fahrenheit), while combustible liquids have flash points at or above that temperature but below 93.3 degrees Celsius (200 degrees Fahrenheit). This classification helps workers recognize materials that pose a fire hazard, enabling them to implement the appropriate safety precautions and handling procedures.

Understanding the characteristics of WHMIS classifications is crucial for workplace safety, particularly in environments where hazardous materials are handled. Classifying materials accurately allows for better training and ensures that everyone is aware of the risks associated with these substances.
