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.
LPG liquid withdrawal fuel leaks. Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an
explosion. Check the LPG liquid withdrawal fuel system for leakage by using a soap and water solution with the fuel system test
pressurized to at least 90 psi (621 kPa). 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.
Hazardous Noise
CAUTION
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.
Hazardous Voltage/Moving Parts
DANGER
DANGER
WARNING
Grounding electrical equipment. Hazardous voltage will cause severe injury or death. Electrocution is possible whenever
electricity is present. Ensure you comply with all applicable codes and standards. Electrically ground the generator set, transfer
switch, and related equipment and electrical circuits. Turn off the main circuit breakers of all power sources before servicing the
equipment. Never contact electrical leads or appliances when standing in water or on wet ground because these conditions
increase the risk of electrocution.
High voltage test. Hazardous voltage will cause severe injury or death. Follow the instructions of the test equipment
manufacturer when performing high-voltage tests on the rotor or stator. An improper test procedure can damage equipment or
lead to generator set failure.
10
Hazardous noise.
Can cause hearing loss.
Never operate the generator set without a muffler or with a faulty exhaust system.
Hazardous voltage.
Will cause severe injury or death.
Disconnect all power sources before opening the enclosure.
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when all guards and electrical enclosures are in place.
Hazardous voltage. Backfeed to the utility system.
Can cause property damage, severe injury, or death.
If the generator set is used for standby power, install an automatic transfer switch to
prevent inadvertent interconnection of standby and normal sources of supply.
