Explosion proof certificate and coal safety certificate are applicable to different places,
Explosion proof certificate generally refers to places used for removing various explosive gases and dust from coal mines underground
Coal safety certificate refers to the safety mark certificate for equipment and products used underground in coal mines
So, whether to apply for an explosion-proof certificate or a coal safety certificate depends on where the product is used. If only used in non coal mine explosive gas and dust areas, having an explosion-proof certificate is sufficient. If coal mines are to be used underground, a coal safety certificate is required, and the two are not interchangeable.
