Hazardous Materials

• compressed gases (pressurized flammable or nonflammable gas)
• flammable liquids (those with a flash point of less than 100 degrees Fahrenheit)
• combustible liquids (those with a flash point greater than 100 degrees Fahrenheit)

White placards indicate the material is an inhalation hazard and/or poison; Black and white placards indicate the material is corrosive; Red and white placards indicate the material is a flammable solid or spontaneously combustible (it depends on the color pattern);

Materials that are health hazards include carcinogens, toxic or highly toxic agents, reproductive toxins, irritants, corrosives, sensitizers, hepatotoxins, nephrotoxins, neurotoxins, those which act on the hematopoietic system, and agents that damage the lungs, skin, eyes, or mucous membranes.

A hazard is something that can cause harm, e.g. electricity, chemicals, working up a ladder, noise, a keyboard, a bully at work, stress, etc. A risk is the chance, high or low, that any hazard will actually cause somebody harm. For example, working alone away from your office can be a hazard.

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.
