Boathouses, Sea Walls and Confined Spaces
NOTICE
Prompt action can make the difference between
life and death.
Aboatoperatorshouldbeawarethatdangerousconcen-
trations of CO can accumulate when a boat, generator or
other engine operated device is operated while the boat
is moored in a confined area such as:

Investigate source of CO and take corrective action.

Boathouses,
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.).
Proximity to sea walls, or
Proximity to other boats.
Keep engine room hatches and doors closed when op-
erating engines, including the generator.

3.
Make sure all exhaust clamps are in place and se-
cured.
Pay attention to prevailing conditions and provide for
ventilation to induce fresh air and minimize exhaust re-
entry. Orient the boat for maximum dissipation of the
exhaust. DO NOT run the boat or boat equipment for
extended periods under these conditions. See Figure
B6.
Make sure ventilation systems work and are not ob-
structed or restricted.
Make sure gaps around the engine room plumbing
and cableways and exhaust system doors, hatches,
and access panels are minimized to reduce the op-
portunityforCOtoentertheaccommodationspace(s).

Pay attention to ventilating the boat.
Orient the boat so it will allow the maximum dissipa-
tion of CO.
Figure B6: The effect of sea walls and other confined spaces.
Be aware that cockpit and deck drains can be a source
of CO ingress into boats, especially boats with cockpit
or decks enclosed with canvas or permanent boat struc-
tures.

Minimize the time spent on getting underway.
In order to minimize CO buildup, do not warm up or
run propulsion engine(s) for extended periods while
the vessel is stationary.

The Effect of Boats Moored Along Side
Aboatoperatorshouldbeawarethatcarbonmonoxideis
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 their boat on other boats in the area. Of prime
concern is the operation of an auxiliary generator where
boats are mooredalongsideeachother. Beawareof the
effectyourexhaustmayhaveonotherboatsandbeaware
that the operation of other boats’ equipment may affect
the carbon monoxide concentration on your boat. See
Figure B7.
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.
