Is it classified as Category A due to fire hazard, but does it not require explosion protection? Could you give an example, please?

There shouldn’t be any. All require explosion protection.
Non-flammable liquids – aren’t they explosion-proof?
For substances such as hydrogen peroxide, and those in Category B like fuming sulfuric acid, is it necessary to determine an explosion-proof area?
The fire hazard of yellow phosphorus is classified as Class A; therefore, explosion protection is not required in facilities where yellow phosphorus is burned to produce phosphoric acid.
Hydrogen peroxide is a strong oxidizing agent that can easily cause combustion or explosion, while sulfuric acid is a highly corrosive substance; when these two substances are used together, the regulations applicable to the more hazardous one shall be followed
They’re not placed together; what it means is whether an explosion-proof design is needed for things like fuming sulfuric acid
Concentrated sulfuric acid is not flammable on its own, but it reacts violently when in contact with flammable materials, which can even lead to combustion; therefore, explosion protection is necessary
