This document is designed to teach learners in secondary and postsecondary electrical trades courses to recognize, evaluate, and control hazards associated with electrical work, The manual's eight sections each include some or all of the following components: instructional text; definitions; case studies illustrating key safety considerations; fact sheets; checklists; and a section summary. Sections 1-3 examine the dangers of electricity, the dangers of electrical shock, and electrical burns. Section 4 presents an overview of a three-stage model for recognizing hazards in workplaces where electrical work is performed, evaluating hazards, and controlling identified hazards. The following are among the specific topics covered in sections 5-8, which address the model's individual stages: (1) recognizing hazards (inadequate wiring, exposed electrical parts, overhead power lines, defective insulation, improper grounding, overloads, wet conditions); (2) evaluating hazards; (3) controlling hazards by developing a safe work environment (locking out and tagging out circuits and equipment; isolating energized components; insulating properly; using ground circuits and equipment); and (4) controlling hazards through safe work practices (work plans, safety plans, ladder safety, precautions in wet conditions, proper wiring, tool maintenance, personal protective equipment). A glossary, endnotes, and an appendix listing pertinent Occupational Health and Safety Administration standards are included. (MN)
