Closed-circuit breathing apparatus testing laboratory.
Abstract Book, U.S. Department of the Interior Conference on the Environment and Safety, April 24-28, 1995. Washington, DC: U.S. Bureau of Mines, 1995 Apr; :31
The Life Support group at the Pittsburgh Research Center has developed a testing laboratory for closed-circuit breathing apparatus used for both escape from and entry into areas with irrespirable atmospheres. These apparatus are used after a mine fire or explosion. Outside of mining, they are used for shipboard and land-based firefighting, and hazardous materials clean-up. The apparatus are tested either on a treadmill using human subjects or on a breathing and metabolic simulator. Apparatus tested are compared with each other and evaluated with respect to human compatibility. We have tested apparatus for the Navy, Air Force, National Fire Protection Association, and apparatus manufacturers. A performance comparison of entry apparatus used in mine rescue, fire service, and hazmat will be presented including information on carbon dioxide levels, breathing resistance and temperature.
