Where combustible or flammable materials are stored or processed there is, in most circumstances, a possibility of their leaking or otherwise having the ability to produce what may be described as an explosive atmosphere in conjunction with the oxygen present in air. This is true for gases, vapours, mists and dusts and, as electricity is widely used in industries and other places where such explosive atmospheres can occur, the propensity of electrical energy to create sparking or hot surfaces presents a possibility that the explosive atmospheres may be ignited with resultant fire or explosion. This hazard has been recognized for many decades - almost since the use of electricity was introduced into mining and other industries - and the precautions taken to overcome this problem date back, in their basic inception, to the turn of the twentieth century and before.
