Electrical equipment for coal mines - Introduction, inspection and maintenance Part 1: For hazardous areas
|Publication Date:||11 February 2014|
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
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
(ii) the regulatory compliance assessment of electrical equipment; or
(iii) the permanent repair, reclamation and overhaul of explosion protected equipment.
