Person Wearable Self-contained Self-rescuer (Pw-scsr).
Issa-aiss-ivss Bull 7 1990 :49-55
The U.S. Bureau of Mines, in a joint effort with the Mine Safety and Health Administration, through contract and in-house research, has refined scsr technology to the point where it is now possible to provide miners with apparatus small enough to be bodily worn with sufficient oxygen for the escaping miners to reach fresh air. Pw- scsr technology based on the sr-100 design is intended as a strict substitute for current scsr's, without any changes in federal regulations. Because the sr-100 is belt-wearable, it is also a replacement for the fsr, enabling simplification of a mine operator's scsr deployment plans.
