Respirators had been used by employees in about 10 percent of the private industry workplaces surveyed in late 2001.
The term respirator refers to any device designed to provide the wearer with respiratory protection against inhalation of a potentially hazardous atmosphere. Dust masks, full-facepiece respirators, and self-contained breathing apparatuses (where air or oxygen is carried in a tank on the worker's back) are examples of respirators.
In nearly half of the 619,400 establishments where respirators were used, they were used by employees on a voluntary basis only, and, in about 12 percent, they were used only when required because of emergencies.
These data are from a special survey conducted by the BLS Injuries, Illnesses and Fatalities Program for the National Institute for Occupational Safety and Health, Centers for Disease Control and Prevention.
