approved red containers clearly
marked GASOLINE.
Propane (LP)—Adequate ventilation
is mandatory. Because propane is
heavier than air, install propane gas
detectors low in a room. Inspect the
detectors per the manufacturer’s
instructions.
Natural Gas—Adequate ventilation is
mandatory. Because natural gas rises,
install natural gas detectors high in a
room. Inspect the detectors per the
manufacturer’s instructions.
Fuel tanks. Explosive fuel vapors
can cause severe injury or death.
Gasoline and other volatile fuels stored
in day tanks or subbase fuel tanks can
cause an explosion. Store only diesel
fuel in tanks.
Draining the fuel system. Explosive
fuel vapors can cause severe injury
or death. Spilled fuel can cause an
explosion. Use a container to catch

explosion. Check the LP vapor gas or
natural gas fuel system for leakage by
using a soap and water solution with
the fuel system test pressurized to
6--8 ounces per square inch
(10--14 inches water column). Do not
use a soap solution containing either
ammonia or chlorine because both
prevent bubble formation. A
successful test depends on the ability
of the solution to bubble.
LP liquid withdrawal fuel leaks.
Explosive fuel vapors can cause
severe injury or death. Fuel leakage
can cause an explosion. Check the LP
liquid withdrawal gas fuel system for
leakage by using a soap and water
solution with the fuel system test
pressurized to at least 90 psi
