Hazard Alert - Methane Explosion

Hazard Alert Message

Miner conducting Gas Test

Coal miners need to be aware that, according to some studies, mine explosions are more likely to happen when the barometer is falling, either in advance of a cold front or at the time a cold front passes; that the greatest number of explosions have occurred on days that cold fronts pass; and that methane drawn out as a result of drops in barometric pressure can be ignited several days later. While an explosion does not occur each time the barometer falls or a cold front passes, the danger of an explosion is increased, so - BE ALERT. Effective explosion prevention demands that employees pay special attention to mines or sections of mines where explosion hazards could develop. All miners must control conditions that could contribute to ignitions, explosions or fire hazards. Everybody has a stake in this because the vigilance of many can be offset by the unsafe acts of one.
