Powdered Soap Forms Another Hazard
Tests conducted by the Experiment Station of the United States Bureau of Mines at Pittsburgh, Pa., have proven that the smooth, flaky soap powder, when suspended in the air, is a highly explosive substance. Tests conducted with soap dust in suspension produced even more violent explosions than were attained with dry coat dust, the cause of many serious accidents in coal mines.
The explosive hazard of soap dust is a serious factor only in the case of suspension of considerable amounts in air, such as might occur in the process of manufacture. Presence of this widely used cleaner medium in the family washing machine carries no hazard whatever.
