Fire Extinguishers in Underground Coal Mines

The Mine Safety and Health Administration (MSHA) is revising the existing standard for the quantity and location of firefighting equipment in underground coal mines to assure that it is readily available to quickly extinguish a fire. In lieu of the existing requirements for rock dust and other firefighting equipment, this final rule allows the use of portable fire extinguishers in working sections of underground anthracite coal mines that have no electrical equipment at the working section and produce less than 300 tons of coal per shift. The rule also requires an additional fire extinguisher in lieu of rock dust at temporary electrical installations in all underground coal mines.
