Toolbox Talk:

Fire Prevention While Welding and Cutting

June 27, 2025

Welding and cutting can easily ignite fires — you must control your surroundings before striking an arc or lighting a torch.

Why It Matters:

Hot slag and sparks can travel over 35 feet, igniting combustibles, fuel vapors, or dust. Many jobsite fires have started because someone failed to prep the work area properly before welding or cutting began.

Key Points:

  • Clear a 35-foot radius of flammable materials before beginning any hot work.
  • Use fire-resistant blankets, shields, or curtains to protect nearby objects.
  • Check above and below the work area — sparks can fall through floor grates or ignite materials stored below.
  • Seal cracks or openings where sparks might travel.
  • Fuel sources (propane tanks, gasoline cans, aerosol containers) must be removed from the area entirely.
  • Keep a fire extinguisher rated for Class C (electrical) or Class B (flammable liquid) nearby.
  • A fire watch is required for at least 30 minutes after work is complete, or longer if hot work was near high-risk areas.

✅ Controlling your environment is just as important as using the right tool.

Ask the Crew:

  • Have we cleared all combustibles within 35 feet?
  • Who is assigned to be our fire watch after cutting or welding?
