THE FIRE HAZARD OF COAL DUST
Two Serious Accidents Result from ignition of Dust Cloud—Miners Burned—Remedies Suggested to Prevent Such Occurrences
THE Bureau of Mines for a number of years has conducted experiments at its experimental mine near Bruceton, Pa., on the explosibility of coal dust, with particular reference to dust explosions in coal mines, and the knowledge so gained may well be applied to the handling of coal dust at industrial plants and elsewhere. Powdered coal is coming into use more and more as a fuel, and the dangets incident to its use should be recognized and guarded against, as a number of accidents have occurred in recent years due to ignorance of this danger or to carelessness. Within the past three years two very serious accidents, under almost identical circumstances, have occurred on the surface at two different coal mines in Southeastern Iowa, due in each case to the sudden ignition of a cloud of fine coal dust.
