Fueling Precautions
Improper fueling procedures are the most common
cause of boat fires. Before fueling your boat, check
the entire fuel system for leaks. Check for weaken-
ing, hardening, swelling, or corrosion of fuel system
components. These include the fuel tank, fuel lines
and fittings, fuel filter, and carburetor. Any sign of
leakage or deterioration requires immediate
replacement before further engine operation.
Before and During Fueling Procedures:
• Make sure that a fire extinguisher is readily
available.
• Safely and securely moor your boat to the dock.
• Turn off the engine and all electrical equipment,
including lights, bilge pump, bilge blower, etc.
• At least one knowledgeable person should be
present.
• Unnecessary individuals should get off the boat.
• Close all hatches, windows, doors, and
compartments.
• Extinguish all cigarettes, cigars, pipes, or other
items that may produce a spark or flame.
Inboard tanks should be grounded.
• The filler pipe should be marked DIESEL.
• The fuel nozzle should be in contact with the
filler pipe to prevent static sparks.
• Fill the fuel tank to less than the rated capacity
to allow for fuel expansion.
• Trim the fuel weight to distribute it equally.
