Does my employer have to pay for my PPE?

It depends on where you work. CCOHS names NWT, Nunavut, Quebec and Saskatchewan as places where employers must provide PPE free. In BC, the employer provides most PPE, but workers supply their own safety footwear, safety headgear, general work gloves and weather clothing.

Does this course qualify me to wear a respirator?

No. It is background knowledge only. Your employer must train you on the PPE used at your site, and respirator users need their employer's respiratory protection program, which includes fit testing.

When should I replace my hard hat?

Replace it after it has been struck, even if it looks fine. Also replace a shell that is cracked, gouged, stiff or chalky, and a suspension that is torn.

Are music earbuds OK as hearing protection?

No. CCOHS says music earphones and headsets are not substitutes for hearing protectors. Wear approved earplugs or earmuffs the whole time you are in noise.

It makes the hazard happen less often
It removes the hazard from the whole workplace
Nothing; it only lowers the wearer's exposure
