ABSTRACT
This chapter outlines the principles, hazards and risks associated with the use of electricity in the workplace. It highlights the control measures that should be taken when working with electrical systems or using electrical equipment in all workplace conditions. The chapter considers voltages up to and including mains voltage and the three principal electrical hazards – electric shock, electric burns and electrical fires and explosions. Detailed safety standards for designers and installers of electrical systems and equipment are given a code of practice, published by the former Institution of Electrical Engineers. All managers should be responsible for the provision of adequate resources of people, material and advice to ensure that the safety of electrical systems under their control is satisfactory and that safe systems of work are in place for all electrical equipment. A static electric shock, perhaps caused by closing a door with a metallic handle, can produce a voltage greater than 10,000V.
