¿Las cestas para minas de carbón requieren un certificado de seguridad del carbón?

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. Nonetheless, for underground applications, a coal safety certificate is compulsory and non-negotiable.
