Why it matters
Electrocution is one of construction's "Fatal Four." Most incidents involve damaged cords, missing GFCIs, or working too close to live parts.
Talk points
- GFCI protection on every temporary power circuit — no exceptions, even for "just a minute".
- Inspect cords daily: exposed conductors, missing ground pins, cracked insulation. Damaged cords leave the site.
- Lockout/tagout before servicing any equipment — verify zero energy, don't trust the switch.
- Stay at least 10 feet from overhead power lines — more for higher voltages. Spotters when equipment works near them.
- Only qualified electricians open panels or work on energized parts.
Ask the crew
- Where's the nearest GFCI on this site — and has anyone tested it?
- Are there overhead lines in today's crane or lift path?
- What equipment gets locked out today, and who holds the lock?
