To identify and manage fire and explosion hazards in areas where hot work is being performed, to prevent fires or explosions that could result in personal injuries, property damage, communi-ty impacts, environmental impacts, or business impacts.
Examples activities that would require use of a Hot Work SWP:
“Naked Flame” Activities
- Gas cutting and welding
- Electric arc welding
- Open flame boilers / space heaters
- Brazing
- Soldering
- Stress relief and heat treatment
- Use of explosives
- Exposure of pyrophoric scale
“Spark Potential” Activities
- Cutting and grinding
- Needle guns
- Sand blasting / abrasive blasting
- Internal combustion engines (e.g., trucks, forklifts, etc.)
- Use of non-intrinsically safe electrical equipment
- Stress relief and heat treatment
- Opening sealed and/or pressurized electrical equipment (e.g., junction boxes, switches, light fixtures, etc.)
- Electrostatic discharge / static electricity
- Jackhammers / chippers
- Hammering / impact tools
- Opening/operating equipment that could create a flammable source in the presence of existing ignition sources (e.g., process heater fireboxes)
