• Cutting and welding equipment in good repair

• Within 35 feet; floors swept clean of combustible, no combustible material or flammable liquids, all wall and floor openings covered, and covers suspended beneath work to collect sparks

• When working on enclosed equipment and in confined space, equipment and area is free of flammable vapors

• Fire watch provided during and 30 minutes after operation (60 minutes for torch applied roofing operations)

• Portable fire extinguisher with adequate rating available in the immediate vicinity

• Standpipe system in service where installed

• Protection of any sprinkler heads when hot work is in close proximity

• Smoking prohibited in immediate vicinity

• Non-combustible shields provided when hot work is done near combustible walls, partitions, floors, roofs
