Abstract

This Standard sets out requirements for the inspection and maintenance of electrical equipment designed for use in hazardous areas in and around underground coal mines.

Scope

This Standard sets out requirements for the inspection and maintenance of electrical equipment designed for use in hazardous areas in and around underground coal mines.
Section 2 provides general requirements that are fundamental to the safe use of electrical equipment in hazardous areas. Section 3 provides specific requirements for each type of explosion-protection technique.
This Standard is intended to be applied where there is a potential risk due to the presence of explosive gas, dust mixtures and combustible dust layers. It does not apply to -
(a) surface infrastructure, typically Group II or Group III classified areas, other than gas drainage and borehole dewatering areas that could negatively impact on an underground mine workings;
(b) areas where a risk can arise due to the presence of hybrid mixtures;
(c) areas where small quantities of flammable materials are introduced for maintenance purposes; or
(d) shotfiring activities and associated equipment.
This Standard does not include -
(i) electrical installation and inspection requirements not directly associated with an explosion-protection technique;
(ii) the regulatory compliance assessment of electrical equipment; or
(iii) the permanent repair, reclamation and overhaul of explosion protected equipment.
