Gas station explosion-proof
Thread Content
I did a safety assessment of gas stations and found that almost all the electrical equipment and plugs in the office buildings of gas stations are not explosion-proof (even mobile phone calls are not allowed in gas stations) Question: Do electrical equipment in gas station office buildings need to be explosion-proof?
As long as you are not in an explosion hazard area, you do not need to use explosion-proof electrical appliances. However, from the perspective of intrinsic safety, it is safer to use fire-proof electrical appliances.
Of course it is better to use explosion-proof ones, and if the safety evaluation is strict, you should consider the probability that the gasoline molecules emitted from the refueling area will reach the explosion limit in the office area. This is my opinion. After all, I have not done any evaluation.
I have never heard of any accidents occurring due to this, so there is no need to consider it in the evaluation.
Electrical equipment in office buildings does not need to be explosion-proof! Generally not in explosion hazard areas! ! ! !
According to the relevant requirements of the "Code for Design of Electrical Equipment in Explosive and Fire Hazardous Environments", the key is to see whether the environment is within the explosion area (Zone 1 or 2). If it is in a fire and explosion environment, then the corresponding electrical appliances should be explosion-proof electrical appliances that meet the requirements. Electrical appliances do not need to be explosion-proof if they are not located in an explosive environment. Please refer to the relevant provisions of the "Code for Design of Electrical Installations in Explosive and Fire Hazardous Environments" for details.
If you are not in an explosion-risk area, you don’t need to use explosion-proof equipment. Generally, the distance is regulated. You can refer to the regulations for gas station construction.
Electrical equipment in gas station office buildings does not need to be explosion-proof, as regulations stipulate it.
I checked the gas station design specifications and found that most gas station buildings are not in explosion hazard areas.
Appendix B of the "Code for Design and Construction of Automobile Gas Stations" GB50156-2002 (2006 edition) clearly stipulates the explosion hazard areas and classifications.
Appendix B of "Code for Design and Construction of Automobile Gas Stations" GB50156-2002 (2006 edition) clearly stipulates the division of explosion hazard areas and levels. Explosion-proof electrical appliances must be used in explosion hazard areas. There are no requirements for those not in explosion hazardous areas.
