Specifies requirements for the introduction, examination, maintenance, in situ repair and allowable modifications to electrical equipment designed for use in hazardous areas in and around underground coal mines.

This Standard sets out requirements for the introduction, examination, maintenance, in situ repair and allowable modifications to electrical equipment designed for use in hazardous areas in and around underground coal mines. It details methods for introduction, examination, maintenance, commissioning and testing required to ensure safety, compliance with relevant Standards and supporting documentation for the different types of explosion-protection apparatus and reliable operation while the equipment is in service.Where other explosion-protection techniques, other than those mentioned in the Standard, are utilized the risks need to be assessed and appropriate management plans developed, within the same context of this Standard.This Standard provides guidelines covering the life cycle of the equipment including initial commissioning, maintenance, modification and the removal from service for overhaul. Attention is also drawn to the various Acts, the regulations under these Acts and also any other appropriate statutory requirements or by-laws. These place the prime responsibility for complying with specific safety requirements on the manufacturer and user of the equipment.
