Lightning Safety During Outdoor Work

June 27, 2025

When thunderstorms roll in, lightning becomes a serious threat — especially on open construction sites with cranes, rebar, scaffolding, and other conductive materials.

Why It Matters:

Lightning strikes kill and injure construction workers every year. Being outdoors with metal tools or equipment significantly increases the risk.

Key Points:

  • Stop work immediately when thunder is heard or lightning is seen.
  • Seek shelter in a fully enclosed building or metal-topped vehicle — open structures like tents or partially built buildings are not safe.
  • Avoid working near tall isolated objects, scaffolds, cranes, and metal materials during storms.
  • Stay away from puddles, wet concrete, and water-filled trenches, which can conduct electricity.
  • Resume work only 30 minutes after the last thunderclap.

✅ If you can hear thunder, you’re close enough to be struck.

Ask the Crew:

  • What’s our plan if lightning is detected during a shift?
  • Do we have access to safe shelter within reach of this work area?
