An estimated 5 million workers are required to wear respirators in 1.3 million 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, other diseases, or death.
Compliance with the OSHA Respiratory Protection Standard could avert hundreds of deaths and thousands of illnesses annually.
