BS 6704 describes the concept of ensuring electrical safety in hazardous atmospheres in coal mines by means of the type of protection `i' (intrinsic safety).
BS 6704 provides background information and gives recommendations on the selection, installation, inspection and testing, and maintenance and repair of intrinsically safe electrical apparatus, systems and networks.
BS 6704 on electrical equipment in coal mines is helpful for:
Having access to reliable guidelines is essential to install and maintain intrinsically safe electrical equipment in coal mines. BS 6704 provides manufacturers with the requirements, guidelines for inspection and safety measures which allows them to effectively install and maintain intrinsically safe electrical equipment in coal mines.
