Does the electrical system of an oxygen station need to be explosion-proof?
Thread Content
I am in charge of a company that is engaged in oxygen repackaging; it has a tank of liquid oxygen, which is then vaporized and filled into gas cylinders. The question is: does the electrical system in the repackaging area need to be explosion-proof? According to the design specifications for oxygen stations, the repackaging area is classified as a Zone 21 fire zone – does this mean that the electrical system there also needs to be explosion-proof?
No, oxygen itself does not explode, and the site conditions do not indicate the presence of any explosive gases.
It’s not necessary, but if you have enough money, you can opt for explosion-proof electrical appliances; it can’t hurt in any case.
It’s necessary; it’s specified in the standards. I forgot which standard it is
Let me make it clear: pure oxygen does not have any explosion-proof requirements
If the design institute states that it is an explosion-proof area, then it is necessary; if it says it is not an explosion-proof area, then it is not necessary
Appropriate-rated explosion-proof electrical equipment must be used in explosion-proof areas; it is not prohibited to use such equipment there, but this does lead to increased costs. If you really have the money and your boss doesn’t mind, then it’s fine, but it will be a matter of conscience. Oxygen is an oxidizing gas and does not require explosion-proof equipment.
Although oxygen is not flammable in itself, its role in facilitating combustion makes it particularly dangerous. It is classified as a Class B flammable gas under both petrochemical regulations and building codes; therefore, explosion-proof measures are necessary
