Recommended Guidelines for Oxygen Self-Rescuers. Volume 4. Underground Non-Coal Mining

摘要

The Bureau of Mines initiated a contract for the development of guidelines for the storage and use of self-contained self-rescuers (SCSR) in underground noncoal mines. An SCSR is a device capable of supplying, in an emergency, 1 hour of self-contained oxygen (no breathing of mine air). The information and recommendations in this report were developed primarily from three sources: discussions with mine representatives (including management, labor, and government), site visits in underground mines, and a detailed analysis of every reported noncoal accident that produced hazardous atmosphere during the 5-year period 1976-80, plus 10 other major incidents from prior years.
