To meet the required criteria for the explosion proof rating, an enclosure must be able to contain an explosion originating within its housing and prevent sparks from igniting vapours, gases, dust or fibres in the air surrounding it. Therefore, explosion proof, when referring to electrical enclosures, does not mean that it is able to withstand an exterior explosion. Instead, it is the enclosures ability to prevent an internal spark or explosion from causing a much larger blast.
