TABLE OF CONTENTS Electricity is a widely used, efficient and convenient, but potentially hazardous method of transmitting and using energy. It is in use in every factory, workshop, laboratory and office in the country. Any use of electricity has the potential to be very hazardous with possible fatal results. Legislation has been in place for many years to control and regulate the use of electrical energy and the activities associated with its use. Such legislation provides a framework for the standards required in the design, installation, maintenance and use of electrical equipment and systems and the supervision of these activities to minimize the risk of injury. Electrical work from the largest to the smallest installation must be carried out by people known to be competent to undertake such work. New installations always require expert advice at all appropriate levels to cover both design aspects of the system and its associated equipment. Electrical systems and equipment must be properly selected, installed, used and maintained.
Approximately 8% of all fatalities at work are caused by electric shock. Over the last few years, there have been between 12 and 16 employee deaths due to electricity, between 210 and 258 major accidents and about 500 over three-day accidents each year. The majority of the fatalities occur in the agriculture, extractive and utility supply and service industries, while the majority of the major accidents happen in the manufacturing, construction and service industries.
