Respirators should be used for protection only when engineering controls have been shown to be infeasible for the control of the hazard or during the interim period when engineering controls are being installed. (Refer to Exposure Control Priority).

When would you use a respirator?

Respirator masks protect individuals from hazards like dangerous chemicals or particulates like dust, dirt, soot, smoke and drops of liquid. Respiratory masks should be used for protection in many industries. Workers who may be exposed to gasses or vapors, like in chemical manufacturing, should wear a protective mask.

What type of hazards require you to use a respirator?

Millions of workers are required to wear respirators in various workplaces throughout the United States. Respirators protect workers against insufficient oxygen environments, harmful dusts, fogs, smokes, mists, gases, vapors, and sprays. These hazards may cause cancer, lung impairment, diseases, or death.
