Arc Flash Hazard – Working safely in accordance with the requirements of the Electricity at Work Regulations 1989 is about decision making. This includes the decision to work live in the first place through risk assessment. One of the factors that would need to be taken into account in deciding whether live proximity work could proceed is stated in the memorandum of guidance to the EAW Regulations “the level of risk involved in working live and the effectiveness of the precautions available set against economic need to perform that work”.
