Equipment with high fire potential includes any of the following:

  • Pumps with a rated capacity over 150 gpm (34 m3/h) handling light ends.
  • Pumps with a rated capacity over 200 gpm (45 m3/h) handling flammable liquids or combustible liquids when handled at temperatures above or within 15°F (8°C) of their closed cup flash point.
  • Gas compressors over 200 hp (150 kW) handling flammable materials.
  • Fired heaters handling flammable or combustible liquids in the tubes.
  • Vessels, heat exchangers (including air-cooled) and other equipment containing flammable liquids at or above 600°F (315°C), or above their auto-ignition temperature, whichever is less.
  • Reactors that operate at or above 500 psig (3450 kPa) pressure or are capable of producing exothermic or runaway reactions.
