Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
Do I need a Coal Mine Safety Certificate if the product already has an explosion-proof certification?
Explosion-proof certificates and coal safety certificates are applicable to different venues.
Inherently safe certificate generally refers to facilities used in places where explosive gases and dusts, excluding those in coal mine shafts, are present.
Coal Mine Safety Certificate refers to the safety certification mark 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 used only in non-coal mining explosive gas and dust environments, a防爆certificate is sufficient.
If mining operations are to be conducted underground, a Coal Safety Certificate is mandatory; the two certificates are mutually non-transferable.
