   Focus Four [Electrocution] Toolbox Talks 1: What increases your risk of electrocution?

   • [Ask the following questions and give time for answers.]
   • 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
   • [Relate this incident or, better, one you know.]
   • 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.
   • [Ask the following question and ensure every item is covered.]
   • 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.
   • [Ask the following questions about this site and ensure every item is covered.]

   Focus Four [Electrocution] Toolbox Talks 2:

   • What protective devices and procedures can you use to prevent electrocution?
   • [Ask the following questions and give time for answers.]
   • What are the hazards? Bodily contact with electricity due to faulty equipment, ungrounded or damaged equipment, wet conditions, etc.
   • What are the results? Shock, fire, burns, falls or death
   • What should we look for? Proper training in using engineering controls (e.g. GFCIs, proper cords), assured equipment grounding conductor written program, electrical testing meters [Relate this incident or, better, one you know.]
   • Actual Incident: A 29-year- old male welder was electrocuted and died when he contacted an energized receptacle end of an extension cord. It was found that the welding unit and cord were incompatible; however, both the welding cord and extension cord were damaged allowing them to be used together. The result was an ungrounded system that killed a worker.

   Focus Four [Electrocution] Toolbox Talks 3: How can we prevent electrocutions while using power tools?

   • [Ask the following questions and give time for answers.]
   • What are the hazards? Bodily contact with electricity
   • What are the results? Shock, fire, burns, falls or death
   • What should we look for? Tools that aren’t double-insulated, damaged tools and cords, incorrect cords, wet conditions, tools used improperly
   • [Relate this incident or, better, one you know.]
   • Actual Incident: A 45-year-old male electrician was electrocuted when he contacted an energized 1/2” electric drill casing. The victim was working in wet conditions and using a single insulated drill attached to damaged extensions cords run through water. [Ask the following question and ensure every item is covered.]
   • How do we prevent these results?
   • Get proper training on manufacturers’ tool use and specs.
   • Inspect tool before each use according to manufacturers’ instructions.
   • Do not use damaged tools, remove them from service.
   • Use only battery-powered tools in wet conditions.
   • Use with GFCI.
   • Use with properly sized and intact cords.
   • [Ask the following questions about this site and ensure every item is covered.]
