Technical Assistance Report No. TA-80-119, Self-Contained Self- Rescuer.
The physiologic effects of using a NIOSH approved one hour self rescuer (SCSR) respiratory protective device on mine workers was evaluated. Forty two subjects either crawled or walked out of a mine shaft while wearing the SCSR. Of these subjects, 10 later performed exercises on a treadmill while wearing the SCSR and their physiological responses were monitored. During the field tests, 16 subjects reported some discomfort from the self rescuer itself, including dry mouth, uncomfortable shoulder straps, discomfort from the mouthpiece, and lens fogging. The laboratory treadmill study showed no evidence of reduction in physiological performance associated with the use of the SCSR. A suggested health screening program for subsequent trials that emphasizes the health screening of test subjects is presented.
