  • Description:
    "A joint effort by the U.S. Bureau of Mines (USBM) and the U.S. Mine Safety and Health Administration (MSHA) was undertaken to determine how well self-contained self-rescuers (SCRS's), deployed in accordance with Federal regulations (30 CFR 75.1714), help up in the underground environment with regard to both physical damage and aging. The report findings regarding laboratory-tested SCSR's in the fourth phase of testing from 1989 to 1993. The SCSR's were tested on human subjects and on a breathing and metabolic simulator (BMS). These results indicate that most of the apparatus, if they pass their inspection criteria, perform as expected except units with manufacturing defects. However, when the apparatus are carried in and out of the mine daily and stored at the working section, they may suffer abuse." - NIOSHTIC-2
