ABSTRACT
This chapter explains the principles, regulatory requirements and procedures for completing the safe isolation of electrical circuits and complete electrical installations. It then focuses on how to complete the reporting and recording of electrical fault diagnosis and correction work. The chapter also explains how to complete the preparatory work prior to fault diagnosis and correction work. It then highlights the procedures and techniques for diagnosing and correcting electrical faults. A prime cause of electrical fires stems from badly formed electrical connections. The source of a possible fault is at the point of human contact with the electrical system. The British Standards concerned with hazardous areas were first published in the 1920s and were concerned with the connection of electrical apparatus in the mining industry. A dangerous situation occurs when the static charge has built up to a potential capable of striking an arc through the air gap separating the two surfaces.
