Respiratory protection
Employers are required to provide workers with appropriate respirators wherever workers are exposed to hazardous substances in the air. This includes gases and vapours, dusts, fibres, mists, fumes, and bioaerosols. Different hazards require different types of respirators, so it is important to choose the right respirator for the breathing hazards in your workplace. Some respirators must also be fitted with the correct filter or cartridge in order to be effective.
