The objective of this Handbook is to provide service facilities, equipment owner and/or operators and relevant regulatory authorities involved in the repair and overhaul of electrical equipment in hazardous areas with guidance to ensure safety and compliance with the relevant existing Standards. The Handbook also offers additional guidance on techniques and special processes necessary to ensure consistent and reliable delivery of repaired and overhauled equipment and cables.

This Handbook provides guidance for the repair and overhaul of explosion-protected electrical equipment used in hazardous areas (defined in AS/NZS 60079.0).The Handbook covers equipment with a Group I designation for coal mining; Group II where flammable gases and vapours may be present; and Group III which includes equipment used in the presence of combustible dusts. This Handbook details the methods of overhaul, repair, examination and the testing required to ensure safety and compliance with the relevant Standards for the different equipment explosion-protection techniques. It covers the several types of explosion-protection techniques currently in use and provides guidance for repair and overhaul service facilities.The soon to be published revision of AS/NZS 3800 (and IEC 60079-19 Edition 3) offer a performance-based approach to the overhaul of electrical equipment for use in hazardous areas. In many applications it was felt it was necessary to establish guidance to standardise the approach for inspection, repair and overhaul techniques and methods, and to provide a repository where expert knowledge can be accumulated from experience and disseminated for the benefit of stakeholders.The objective of this Handbook is to provide service facilities, equipment owner and/or operators and relevant regulatory authorities involved in the repair and overhaul of electrical equipment in hazardous areas with guidance to ensure safety and compliance with the relevant existing Standards.The Handbook also offers additional guidance on techniques and special processes necessary to ensure consistent and reliable delivery of repaired and overhauled equipment and cables.This document is to be read initially in conjunction with AS/NZS 3800 and IEC 60079-19 Edition 3, the recognized international Standard for repair and overhaul of explosion-protected electrical equipment. In anticipation of the soon-to-be published revised AS/NZS 3800 (and IEC 60079 Edition 3), where possible, reference to these documents has been quoted throughout the text.
