Servicing the fuel system. A flash fire can cause severe injury or death. Do not smoke or permit flames or sparks near the
fuel injection system, fuel line, fuel filter, fuel pump, or other potential sources of spilled fuels or fuel vapors. Catch fuels in an
approved container when removing the fuel line or fuel system.
Servicing the air cleaner. A sudden backfire can cause severe injury or death. Do not operate the generator set with the
air cleaner/silencer removed.
Combustible materials. A sudden flash fire can cause severe injury or death. Do not smoke or permit flames or sparks
near the generator set. Keep the compartment and the generator set clean and free of debris to minimize the risk of fire. Catch
fuels in an approved container. Wipe up spilled fuels and engine oil.
Combustible materials. A fire can cause severe injury or death. Generator set engine fuels and fuel vapors are flammable
and explosive. Handle these materials carefully to minimize the risk of fire or explosion. Equip the compartment or nearby area
with a fully charged fire extinguisher. Select a fire extinguisher rated ABC or BC for electrical fires or as recommended by the
local fire code or an authorized agency. Train all personnel on fire extinguisher operation and fire prevention procedures.
Exhaust System
Carbon monoxide symptoms. Carbon monoxide can cause severe nausea, fainting, or death. Carbon monoxide is a
poisonous gas present in exhaust gases. Carbon monoxide is an odorless, colorless, tasteless, nonirritating gas that can cause
death if inhaled for even a short time. Carbon monoxide poisoning symptoms include but are not limited to the following:
• Light-headedness, dizziness
• Physical fatigue, weakness in joints and muscles
• Sleepiness, mental fatigue, inability to concentrate or speak clearly, blurred vision
• Stomachache, vomiting, nausea
If experiencing any of these symptoms and carbon monoxide poisoning is possible, seek fresh air immediately and remain active.
Do not sit, lie down, or fall asleep. Alert others to the possibility of carbon monoxide poisoning. Seek medical attention if the
condition of affected persons does not improve within minutes of breathing fresh air.
Inspecting the exhaust system. Carbon monoxide can cause severe nausea, fainting, or death. For the safety of the craft’s
occupants, install a carbon monoxide detector. Never operate the generator set without a functioning carbon monoxide detector.
Inspect the detector before each generator set use.
Operating the generator set. Carbon monoxide can cause severe nausea, fainting, or death. Be especially careful if
operating the generator set when moored or anchored under calm conditions because gases may accumulate. If operating the
generator set dockside, moor the craft so that the exhaust discharges on the lee side (the side sheltered from the wind). Always
be aware of others, making sure your exhaust is directed away from other boats and buildings.
