ABSTRACT:
An explosion proof vault for housing electrical equipment is isolated from ambient air by the provision of an auxiliary expansion chamber. The auxiliary expansion chamber is coupled to the explosion proof casing and an inelastic bladder is located in the auxiliary expansion chamber in fluid communication with the explosion proof casing. An airtight seal around the mouth of the bladder prevents the passage of air between the explosion proof casing and the auxiliary expansion chamber except within the bladder.
