Course ID


This course is designed to teach trainees about electrical hazards and about the protective devices and safety practices that can help prevent injuries and equipment damage on the job. The course discusses safety hazards and protective devices. It also presents a step-by-step explanation of safety practices associated with switching, tagging, testing, and protective grounding.


Explain the importance of following safety practices on the job.

  • Describe some of the electrical hazards faced on the job.
  • Identify some protective devices designed to prevent injuries to personnel and damage to electrical equipment.
  • Describe how to safely switch, tag, test, and ground a circuit.


Introduction to Electrical Safety

  • Explain why arcs, faults, and the invisibility of electricity can be dangerous.
  • Describe general safety practices that apply to most electrical jobs.

Protective Devices

  • Explain what a protective device is.
  • Describe how fuses, circuit breakers, and reclosers can operate in an electrical system to reduce the dangers created by faults.

Switching and Tagging

  • Describe the procedures of switching and tagging.
  • Explain how switching and tagging help protect workers from the dangers associated with electrical hazards.


  • Explain why testing is important.
  • Describe how noisy testers, statiscopes, and phasing test sets are used to test circuits.

Protective Grounding

  • Explain what protective grounding is.
  • Describe how a de-energized line can become accidentally energized.
  • Explain the difference between a ground switch and a temporary ground.
  • Describe how a temporary ground can be installed.
