NOTICE
Prompt action can make the difference between
life and death.
5. Ventilate area.
6. Investigate source of CO and take corrective ac-
tion.
G. Inspection
Look and listen for leaks in the exhaust systems of both
the generator and propulsion engine(s). Look for discol-
oration around joints in the system (water leaks, carbon,
stains, etc.).
1. Make sure all exhaust clamps are in place and se-
cured.
2. Make sure ventilation systems work and are not ob-
structed or restricted.
3. Make sure gaps around the engine room plumbing
and cableways and exhaust system doors, hatches,
and access panels are minimized to reduce the op-
portunity for CO to enter the accommodation
space(s).
H. Operation
Cold Start vs. Warm Start: CO production is greater while
the combustion chamber surfaces and gas passages
are cold versus when they are warm. A boat operator
should:
1. Pay attention to ventilating the boat.
2. Orient the boat so it will allow the maximum dissipa-
tion of CO.
3. Minimize the time spent on getting underway.
The following are examples of possible situa-
tions where carbon monoxide can accumulate
within your boat while docked, anchored, or un-
derway. Become familiar with these examples
and their precautions to prevent dangerous
accidents or death.

I. Boathouses, Sea Walls and Other Boats
A boat operator should be aware that dangerous con-
centrations of CO can accumulate when a boat, genera-
tor or other engine operated device is operated while the
boat is moored in a confined area such as:
1. Boathouses,
2. Proximity to sea walls, or
3. Proximity to other boats.
Orient the boat for maximum dissipation of the exhaust
or DO NOT run the boat or boat equipment for extended
periods under these conditions. See Figure B7.
Figure B7: The effect of sea walls and other confined spaces.
A boat operator should be aware that carbon monoxide
is emitted from any boat’s exhaust. The operation, moor-
ing, and anchoring in an area containing other boats may
be in an atmosphere containing CO not of the operator’s
making. An operator likewise needs to be aware of the
effect of his actions on other boats. Of prime concern is
the operation of an auxiliary generator with boats moored
along side each other. Be aware of the effect your ex-
haust may have on other vessels and be aware that the
operation of other vessel’s equipment may affect the car-
bon monoxide concentration on your vessel. See Fig-
ure B8.
