Australian Energy Council - ARC Flash Guidance Publication


In November 2015 two workers at AGL Energy’s Liddell Power Station were injured following a serious arc flash incident.

As with all serious workplace safety accidents, SafeWork NSW conducted an investigation to understand how the incident occurred, and how to prevent similar incidents happening again.

A SafeWork NSW investigation is also conducted to determine whether a business, organisation or individuals should face prosecution, following a workplace safety incident. An alternative to prosecution is for an organisation to negotiate an Enforceable Undertaking (EU) with SafeWork NSW. An EU is a legally binding agreement that an organisation will carry out specific safety improvement activities and demonstrate on-going commitment to improved safety and compliance.

The AGL EU contains several initiatives designed to improve electrical critical risk identification, arc flash education, safety culture and leadership at AGL Energy and within the broader energy industry, and also increase electrical safety awareness in the broader community.

Our role

One of the AGL EU initiatives was to produce an Arc Flash guidance publication on electrical arc flash hazards and best practice control measures to eliminate or minimise the risk of arc flash.

Thomson Bridge was retained to lead the drafting of this important guideline.

This paper was published by the Australian Energy Council (AEC) and can be downloaded here.

Thomson Bridge is proud to have worked on this assignment with the AEC, together with a cross section of the electricity generation industry practitioners and professionals from Alinta Energy, CS Energy, Origin Energy, AGL Energy, Hydro Tasmania, Delta Electricity, Snowy Hydro, ENGIE, Stanwell Corporation, along with Palisade Asset Management.

This AEC Electrical Arc Flash Hazard Management Guideline contains information that should be considered for application when electrical workers are required to perform any activity on or near electrical equipment where arc flash hazards exist.
