Os cestos suspensos para minas de carvão exigem um certificado de segurança de carvão

Coal mine baskets, destined for subterranean use, mandate a coal safety certificate for compliance.

Explosion-proof products not intended for underground use can be adapted to Zone 2 explosion-proof standards and do not require a coal safety certificate. Apesar disso, for underground applications, a coal safety certificate is compulsory and non-negotiable.
