life and death.
G. Inspection
Look and listen for leaks in the exhaust systems
of both the generator (if applicable) and propulsion
engine(s). Look for discoloration around joints in the
system (water leaks, carbon, stains, etc.).
1. Make sure all exhaust clamps are in place and
secured.
2. Make sure ventilation systems work and are not
obstructed or restricted.
3. Make sure gaps around the engine room plumb-
ing and cableways and exhaust system doors,
hatches, and access panels are mini mized to
reduce the opportunity for CO to enter the
accommodation space(s).
H. Operation
while the combustion chamber surfaces and gas
passages are cold versus when they are warm.
1. Pay attention to ventilating the boat.
2. Orient the boat so it will allow the maximum
dissipation of CO.
3. Minimize the time spent on getting underway.
4. In order to minimize CO buildup, do not warm up
or run propulsion engine(s) for extended periods
while the vessel is stationary.
The following are examples of possible situa-
tions where carbon monoxide can accumulate
underway. Become familiar with these exam-
ples and their precautions to prevent dangerous
accidents or death.
Boating Safety & Information - Section A
A boat operator should be aware that dangerous con-
centrations of CO can accumulate when a boat, gener-
ator or other engine operated device is operated while
1. Boathouses,
2. Proximity to sea walls, or
3. Proximity to other boats.
Keep engine room hatches and doors closed
when operating engines, including the generator
(if applicable).
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 equip ment
for extended periods under these conditions.
See Figure A6.
Figure A6: Minimize Exhaust Re-enty
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 structures.
J. The Effect of Boats Moored Along Side
A boat operator should be aware that carbon monox-
ide is emitted from any boat's exhaust. The operation,
mooring, 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 moored along
side each other. Be aware of the effect your exhaust
may have on other boats and be aware that the
operation of other boats' equipment may affect the
carbon monoxide con centration on your boat.
