MSHA Winter Alert Campaign

MSHA has launched its annual Winter Alert campaign that  brings attention to the numerous hazards miners face when colder weather strikes. According to MSHA, statistics show that coal mine explosions occur more in colder months, mostly due to low humidity and low barometric pressures, combined with seasonal drying of many areas in underground coal mines. Colder weather also brings hazards such as limited visibility, icy roads and walkways, and the freezing and thawing of highwalls at surface mines, which can make them unstable. The campaign encourages mine operators to remove snow and ice in pathways, apply salt and sand where needed, and frequently examine highwalls for stability. In addition, underground coal mine operators should check for adequate ventilation, apply liberal amounts of rock dust, conduct frequent and thorough examinations, and be familiar with emergency procedures that prevent ignitions and explosions.
