F. Treatment (Evaluate, Ventilate, Evacuate,
Investigate, Take Corrective Action)
1. Evaluate the situation and ventilate the area if
possible.
2. Evacuate the area and move affected person(s)
to a fresh air environment.
3. Observe the victim(s).
4. Administer oxygen if available.
5. Contact medical help. If the victim is not breathing,
perform rescue breathing or approved cardiopul-
monary resuscitation (CPR), as appropriate, until
medical help arrives and takes over.
6. Investigate source of CO and take corrective
action.
NOTICE
Prompt action can make the difference be tween
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
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
dissipation of CO.
Boating Safety - Section B
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
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 Confined Spaces
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
the boat is moored in a confined area such as:
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 B6.
Figure B6: 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.
