Halogenated Hydrocarbons
Halogenated hydrocarbons are a family of chemical compounds characterized by the presence of halogen elements
(fluorine, chlorine, bromine, etc.). These compounds are used in refrigerants, cleaning agents, and solvents and are
heavier than air, a fact that should be kept in mind when determining the installation location of heaters and building
exhaust systems.
⚠ CAUTION ⚠
CORROSION HAZARD: Halogenated hydrocarbons, when exposed to flame, precipitate with any
condensation present in the heater to form hydrochloric acid, which readily attacks all metals,
including 300 grade stainless steel. Care should be taken to separate these vapors from the
combustion process. An outside air supply MUST BE provided to the burner whenever the presence
of these compounds is suspected.
Mounting Height Requirements
⚠ DANGER ⚠
In aircraft storage and servicing areas, heaters shall be installed at least 10 feet (3 meters) above
the upper surface of wings or of engine enclosures of the highest aircraft housed in the hangar.
The measurement shall be made from the wing or engine enclosure (whichever is higher from the
floor) to the bottom of the heater.
⚠ WARNING ⚠
The vent pipe and internal heater surfaces that are accessible from outside the heater may cause
burns if touched. Suspend the heater a minimum of 8 feet (2.4 meters) above the floor.
NOTE: Suspended heaters are most effective when located as close to the working zone as
possible, and this fact should be kept in mind when determining the mounting heights to be used.
