How to use itBefore hot work starts, the permit authorizer checks precautions and signs. A fire watch stays during and after the work for the time your program sets.

When you need the hot work permit
Sparks travel far and smolder. Many fires start well after the welder has left, which is why fire watch after work matters.
OSHA, fire codes and insurers have hot work requirements. Use your insurer’s form if they require it.

The hot work permit on an ordinary week
A contractor welds a bracket in a storage room. Cardboard is moved out, a fire blanket covers a wall opening, and a fire watch remains after the welding stops. The final check finds no smoldering.
Why a hot work permit matters
OSHA’s welding and cutting rules require combustibles to be moved or protected and a fire watch posted where a fire could develop, and many insurers require a signed permit. The permit puts one person’s name behind the area check, which is the step most often skipped when a repair seems small.

Sample for Lakeview Furniture Outlet in Madison, Wisconsin. Moving combustibles 35 feet follows the usual clearance rule, and the fire watch stays a full hour after welding stops with a separate final check after that.
Where the hot work permit trips people up
Checking only the floor around the work. Look behind walls, above ceilings and below floor openings where sparks can drop.
Assigning the welder as their own fire watch. The fire watch should have no other task while the work is going on.
Signing off without returning after the watch period. Do a final walk to check for smoke, heat or smells before the area is left alone.
Edits most teams make to the hot work permit
Restaurants with hood workShut down cooking and clean grease from the hood area before any welding or grinding near the ductwork.
Roofing crewsAdd torch-down roofing rules and check under the deck, where insulation can smolder unseen.
From the fieldFeel walls on the other side of the work with the back of your hand during the fire watch. Heat that travels through metal can ignite material you cannot see.
Common questions
When is a permit needed?
For hot work outside designated hot work areas.
How long is fire watch?
Per your program, fire code and insurer.
Who authorizes?
A trained supervisor or safety person.
Do contractors need permits?
Yes, on your site.
Can one hot work permit cover a whole week of welding?
Most programs limit a permit to one shift or one day, because stored materials, sprinkler status and nearby work change. For a longer job, reinspect the area and renew the permit each day.
Is grinding hot work if there is no flame?
Yes, abrasive grinding throws sparks that can travel well past the work area and land in combustibles. Use the permit whenever grinding happens outside a designated welding area.
