Do I need a Coal Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
Explosion-proof certificates generally refer to facilities used for explosive gases and dusts, excluding those in coal mine shafts.
Coal Safety Certificate refers to the safety certification mark for equipment and products used in underground coal mines.
So, whether to apply for an explosion-proof certificate or a coal safety certificate depends on where the product is used.
If used only in non-coal mine explosive gas and dust environments, a防爆certificate is sufficient.
If used in underground coal mines, a coal safety certificate is absolutely necessary; the two are mutually non-compliant.
