Do I need to consider explosion protection for 27.5% hydrogen peroxide? Why?
Hydrogen peroxide itself does not explode, but care must be taken of other flammable materials in the environment of use, as hydrogen peroxide acts as a fuel accelerator.
Explosion protection is required; check whether it falls into Category B. There have been many accidents involving hydrogen peroxide, so careful consideration and design are necessary
Explosion prevention mainly concerns the risk of explosions caused by the mixing with other flammable substances, right?
On the one hand, it is due to its oxidizing property; as it is a strong oxidizer, it can cause combustion or explosion when it comes into contact with certain reducing agents. On the other hand, high-purity hydrogen peroxide can decompose rapidly and cause an explosion when exposed to high temperatures or in the presence of catalysts.
Explosion protection is required; hydrogen peroxide decomposes easily to produce oxygen, and oxygen acts as an oxidizing agent.
I would like to ask the experts here: if hydrogen peroxide is diluted to 7.8% and 100 liters of this solution is stored in a workshop, what fire classification should that workshop be assigned to? It is currently a Class C workshop ； How many can be placed at most?
GB50058/1.0.2/4 specifies that explosion protection regulations do not apply to strong oxidizers. Setting an explosion-proof rating is not a requirement of hydrogen peroxide itself, and there is no basis for determining such a rating.
