Respirators protect the user in two basic ways. The first is by the removal of contaminants from the air. Respirators of this type include particulate respirators, which filter out airborne particles; and "gas masks” which filter out chemicals and gases. Other respirators protect by supplying clean respirable air from another source. Respirators that fall into this category include airline respirators, which use compressed air from a remote source; and self-contained breathing apparatus (SCBA), which include their own air supply.
Respirators should only be used as a "last line of defense" when engineering control systems are not feasible. Engineering control systems, such as adequate ventilation or scrubbing of contaminants should be used to negate the need for respirators.
NIOSH issues recommendations for respirator use. Industrial type approvals are in accordance to the NIOSH federal respiratory regulations 42 CFR Part 84. Development of respirator standards are in concert with various partners from government and industry.

Respirator Usage in Private
Sector Firms, 2001
NIOSH and the Bureau of Labor Statistics conducted a voluntary survey
of U.S. employers regarding the use of respirators. The findings are
intended to provide information to develop interventions and to increase
the frequency and effectiveness of respirator use in the workplace.
