Respirator Topic page
A respirator is a personal protective device that is worn on the face, covers at least the nose and mouth, and is used to reduce the wearer’s risk of inhaling hazardous airborne particles, gases, or vapors. Respirators should be used as a “last line of defense.” Respirators protect the user in two basic ways. The first type, air-purifying respirators, removes contaminants from the air. This includes particulate respirators, which filter out airborne particles, and “gas masks,” which filter out chemicals and gases. Air-supplying respirators protect by providing clean air from another source and includes airline respirators and self-contained breathing apparatus.

Long Term Field Evaluations (LTFE)
The Long-Term Field Evaluation (LTFE) program for self-contained self-rescuers (SCSRs) for miners was initiated more than 20 years ago by the U.S. Bureau of Mines. The objective for the LTFE program is to obtain data to determine the expected performance characteristics of SCSRs used in the mining industry. LTFE program results based on scientific principles can provide useful information to monitor expected SCSR performance and assess possible degradation due to the physical stresses of in-mine use. Of utmost concern is the successful performance of any SCSR that passes its inspection criteria specified by the manufacturer. It is such apparatus that must be relied upon in an emergency.
