Respiratory Protection is intended to ensure employee protection from hazardous airborne materials. 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. For NASA Center resources in the area of respiratory protection please go to the center resources page.
