Course Description

In this Understanding NFPA 70E Electrical Hazards and Safe Practices course, you'll learn to recognize electric shock, arc flash, and arc blast hazards. We'll also cover how to build a job safety plan and choose the right protective equipment. These practices are critical for preventing the serious injuries that electrical work can cause. With these foundations in place, we'll move into the specific practices that keep electrical work safe.

We'll examine how to assess electric shock and arc flash risks, detailing the approach boundaries that define safe distances around energized equipment. You'll develop the ability to inspect tools and instruments before each use and select protective equipment matched to each hazard. We'll also address equipment labeling, procedural precautions, and how to respond when equipment could fail to give you a complete understanding of NFPA 70E. By the end, you'll be able to apply NFPA 70E safe work practices to protect yourself and your coworkers.
