  • Description:
    Thirteen miners died as a result of 2 explosions in the Jim Walter Resources No. 5 mine near Brookwood AL in September 2001. Both explosions were ignited in intake air entries, and both were probably ignited by electrical equipment. With few exceptions, permissible equipment is not required in intake air entries of US underground coal mines Researchers with the National Institute for Occupational Safety and Health, Pittsburgh Research Laboratory. studied the electrical equipment ignition sources for the Brookwood and other w disasters to develop recommendations for preventing similar disasters Adherence to National Electrical codeĀ® requirements for flexible cords installed in hazardous (classified) locations may have prevented the second massive Brookwood explosion. The 30 CFR Part 7 requirements for battery assemblies should be reevaluated, taking into consideration United Mine Workers of America recommendations and the Zone 1"increased safety" standard requirements for battery assemblies, Class 1 Division 2 or Zone 2 explosion protection techniques are recommended for intake air equipment so that they do not present a methane air ignition source under normal operation before mine power is shut down during emergencies Battery powered circuits intake air that are likely to remain energized during emergencies should be protected by more stringent protection techniques, to protect rescue/recovery personnel. Index Terms -Class 1 hazardous location, mine explosion, flexible cord, battery assembly, permissible equipment
