Course 809: Focus Four - Electrocution Hazards

Best blog and community forum for safety professionals worldwide

Focus Four [Electrocution] Toolbox Talks 1:

What increases your risk of electrocution?

What are the hazards? Bodily contact with electricity

What are the results? Shock, fire, burns, falls or death

What should we look for? Damaged equipment, faulty wiring, improper cord use, no GFCIs, wet conditions, reverse polarity, potential arc flash areas, lack of assured equipment grounding conductor program

Actual Incident: A 40-year-old male plumber died after lying on his work light while installing plumbing under a house being remodeled. The victim was crawling under the house carrying the work light with him. The wire inside the work light's conduit became bare and energized the light's housing. Investigation of the incident showed a damaged work light was used with no GFCI. Also, the home's electrical system was not properly grounded.

How do we prevent these results?

  • Inspect all electrical equipment before use.
  • Use GFCI with all power tools.
  • Use intact and properly rated cords (i.e. correct AWG).
  • Do not use damaged equipment - take it out of service.
  • Institute an assured equipment grounding conductor program.
  • Do not work in wet conditions with electricity.

Let's talk about our work site now.

  • What factors increase your chance of being electrocuted?
  • Can someone demonstrate how to inspect this tool for electrical safety? (If possible, provide a tool)
  • What are some areas on the site that could use attention pertaining to electrical hazards?
