This article mainly stipulates the requirements for the use of explosion-proof equipment in oil and gas tank farms. The media stored in oil and gas tank farms are generally flammable and explosive. The use of non-explosion-proof tools, electrical facilities, and communication equipment in the oil and gas tank farms poses greater safety hazards and is prone to accidents.

Typical accident case: 

On June 29, 2010, a deflagration accident occurred in a crude oil storage tank of Petro China Liaoyang Petrochemical, causing 5 deaths and 5 injuries. The main cause of the accident was that the hydrocarbon combustibles in the crude oil tank reached the explosive limit during the cleaning operation, which encountered electric sparks from non-explosion-proof general lighting connected to crude oil storage tanks, resulting in deflagration accidents.
