As mine haulage vehicles become larger, the danger to a driver during a fire emergency is increased by the height of the cab above ground. Also, property damage due to fires on bigger trucks can be quite substantial. Through two research and development contracts with the FMC Corporation the Bureau of Mines set out to solve this problem. In the fall and winter of 1972-73 a dual sensing, automatic with manual override fire protection unit was developed. The system was sucessfully demonstrated during fire tests on a 100-ton- capacity truck at the Pima mine, Tucson, Arizona, in April 1973. An automatic fire sensing and suppression system for large haulage vehicles that protects both the engine compartment and brake grid areas of a truck was completed. It senses either, or both, the flame or heat of a fire, then suppresses the fire with pressurized, B-C class powder. Modification and long-term endurance testing of the system is currently underway.(MW)
