Every place I've worked required a hot work permit before any welding could take place. Most businesses prefer that they not burn to the ground.
You may not think you need this level of protection, but you don't want the garage and house burning either.
Hot work permit required for: Welding, grinding, plasma cutting, anything that makes a spark.
35 feet of clear space required. No flammables. Non movable flammables covered with a fire resistant cover.
Sufficient Fire extinguishers at the location. Fire extinguishers from the department cannot be used. Separate person on fire watch not involved with the work. Stays for 30 minutes after work is done.
Work permits are not issued for areas that have explosives, stored flammable liquids, wood dust, propane, lint, oily rags, etc.
Personal protective equipment: Proper helmet and lens, ventilation, screens to protect other workers from viewing the arc.
And that's the tip of the iceberg. Look up hot work permits it you want to see the whole dance and show.
