unless tanks are outside engine compartment.
DO NOT SMOKE OR USE AN OPEN FLAME in
the vicinity of the generator set or fuel tank.
Internal combustion engine fuels are highly flam-
mable.

AND FIRE!
General
• Keep your generating set and the surrounding
area clean and free from obstructions. Remove all
oil deposits; keep the floor clean and dry.
• Provide appropriate fire extinguishers and install
them in convenient locations. Consult your local
fire department for the correct type of ex-
tinguisher to use. Do not use foam or carbon
tetrachloride on electrical fires. Use extinguisher
rated ABC by NFPA.
• Make sure that all fasteners on the generating set
are secure. Tighten supports and clamps, keep
guards in position over fans, driving belts, etc.
• Do not wear loose clothing in the vicinity of
moving parts, or jewelry while working on elec-
trical equipment.
Make sure that oily rags are not left on or nearthe
engine.
Fuel lines must be of steel piping, adequately
secured, and free from leaks. Piping attheengine
should be approved flexible line. Do not use
copper piping on flexible lines as copper will work
harden and become brittle. Use black pipe on
natural gas or gaseous fuels, but not on gasoline
or diesel fuel.
Your engine installation should be equipped with
a means of positive fuel shutoff in applications
when fuel is conducted from a remote source.
Fuels under pressure (e.g. natural gas or liquified
petroleum gas) should be controlled by a positive
shutoff valve, preferably automatic, in addition to
any valve integral with the carburetor or gas
regulator equipment.
