Hot Work and Welding Safety
US & Canada Welding Steel Mechanical
Why it matters
Sparks travel 35 ft (10 m) and smolder for hours - many building fires start with hot work.
Key points
- Hot work permit before any welding, cutting, or grinding outside designated areas.
- Clear or cover combustibles within 35 ft (10 m); wet down where needed.
- Fire watch during work and for 30-60 minutes after it stops.
- Welding screens protect others from arc flash.
- Check both sides of walls and floors before cutting or welding on them.
