Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling, storing, and using fuels.
The fuel system. Explosive fuel vapors can cause severe injury or death. Vaporized fuels are highly explosive. Use extreme
care when handling and storing fuels. Store fuels in a well-ventilated area away from spark-producing equipment and out of the
reach of children. Never add fuel to the tank while the engine is running because spilled fuel may ignite on contact with hot parts
or from sparks. Do not smoke or permit flames or sparks to occur near sources of spilled fuel or fuel vapors. Keep the fuel lines
and connections tight and in good condition. Do not replace flexible fuel lines with rigid lines. Use flexible sections to avoid fuel
line breakage caused by vibration. Do not operate the generator set in the presence of fuel leaks, fuel accumulation, or sparks.
Repair fuel systems before resuming generator set operation.
Gas fuel leaks. Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an explosion. Check the
LPG vapor 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.
Explosive fuel vapors can cause severe injury or death. Take additional precautions when using the following fuels:
Propane (LPG)—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.
Hazardous Noise
Engine noise. Hazardous noise can cause hearing loss. Generator sets not equipped with sound enclosures can produce
noise levels greater than 105 dBA. Prolonged exposure to noise levels greater than 85 dBA can cause permanent hearing loss.
Wear hearing protection when near an operating generator set.
