ABSTRACT
The routine use of electricity and electrical equipment and appliances has resulted in a failure by most people to appreciate the hazards involved. These hazards can be divided into five principal categories are shock to personnel, ignition of combustible materials, overheating and damage to equipment, electrical explosions, and inadvertent activation of equipment. Although most workers fear electricity and its power, or at least have a healthy respect for electricity, on-the-job electrocutions do occur, and the number one cause of fire in the workplace is electricity. For safety and health professionals, electrical safety in water and wastewater treatment plants is an important priority that requires constant vigilance on their part and on the part of all supervisors and workers to ensure that safe work practices are followed when working with or around electrical circuits, and components. In hazard control, facility safety officials must have fundamental knowledge of the electrical materials used, design of components, and placement of electrical equipment.
