Is it necessary to use explosion-proof electrical equipment for the storage and use of hydrogen peroxide?

Thread Content

Hydrogen peroxide is a strong oxidizing agent that can decompose on its own under short-wave light, in the presence of dust, caustic soda, or heat, resulting in a gas-phase explosion. Therefore, the workshops used for storing them are designed to be explosion-proof, but do the motors, control cabinets, and lighting fixtures in these workshops also need to be explosion-proof electrical devices? Refer to GB50058; hydrogen peroxide is not covered by this standard, and it is therefore impossible to determine the explosion-proof area or the explosion-proof rating. After reading posts on forums, some people say that an explosion-proof rating of IIAT6 in Zone 2 should be considered, while others argue that this is an overkill, as this substance can explode on its own without the need for an ignition source. So I would like to ask the experts: is it necessary to use explosion-proof electrical equipment for the storage and use of this hydrogen peroxide?
