• Fueling
a) Personnel involved with fueling shall be qualified and thoroughly familiar with
the manufacturer's instructions and applicable federal, state, and local regula-
tions regarding the safe fueling of heating units.
b) Only the type of fuel specified on the heater's data plate shall be used.

ture.
f) All fuel storage shall be located a minimum of 25 feet from heaters, torches,
welding equipment, and similar sources of ignition (exception: the fuel reservoir
integral with the heater unit).
g) Whenever possible, fuel storage shall be confined to areas where floor penetra-
tions do not permit fuel to drip onto or be ignited by a fire at lower elevation.
h) Fuel storage shall be in accordance with the federal, state, or local authority hav-
ing jurisdiction.
• Never use heater where gasoline, paint thinner, or other highly flammable vapors are
