Continued

 

gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels.

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.

 

 

c)

All flame, including the pilot light, if any, shall be extinguished and the heater

 

 

 

allowed to cool, prior to fueling.

 

 

 

 

d)

During fueling, all fuel lines and fuel-line connections shall be inspected for leaks.

 

 

 

Any leaks shall be repaired prior to returning the heater to service.

 

 

e)

At no time shall more than one day's supply of heater fuel be stored inside a

 

 

 

building in the vicinity of the heater. Bulk fuel storage shall be outside the struc-

 

 

 

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-
