This manual will present many topics. There are four main types of electrical injuries: electrocution (death due to electric shock), electric shock, burns, and falls. The dangers of electricity, electrical shock, and the resulting injuries will be discussed. The various electrical hazards will be described. You will learn about the safety model, an important tool for recognizing, evaluating, and controlling hazards. Important definitions and notes are shown in the margins. To give you an idea of the hazards caused by electricity, case studies about real-life deaths will be described.
