Do we need to consider electrical explosion protection for hydrogen peroxide, concentrated sulfuric acid, nitric acid, etc.?
In addition to considering the fire and explosion hazards of the medium being transported, it is also necessary to consider whether electrical equipment such as your pumps is installed in an explosion-proof area. It is necessary to communicate with the electrical department to determine what the explosion-proof area requirements are for these types of pumps.
It’s not in the explosion-proof area; it’s used in the manufacturing process, and the electrical details are unclear as well
It is necessary to determine this based on the explosion-proof properties of these substances; refer to GB50058 to find out which explosion-proof category these media fall into, or whether they are not subject to any explosion-proof requirements. This will help determine the level of explosion-proof classification for the electrical installation, and thus decide whether an explosion-proof design is required
I guess it’s not necessary. One also has to consider whether there will be any reactions between electricity and gas, and there’s no clear answer to that either
It is related to the concentration of the medium; for example, electrical equipment within the explosion zone of high-concentration hydrogen peroxide requires explosion protection.
