11. Nausea
12. Dizziness
13. Fatigue
14. Vomiting
15. Collapse
16. Convulsions
NOTICE
The order of the above list is generally the se-
quence of appearance of symptoms. However,
the order of appearance may change for differ-
ent people.
NOTICE
The symptoms of Carbon monoxide poison-
ing may easily be mistaken for seasickness.
F. Treatment (Evacuate, Ventilate, Investigate, Take
Corrective Action)
1. Move the person to fresh air.
2. Administer oxygen if available.
3. Contact Medical help.
4. If the victim is not breathing, perform artificial respi-
ration per approved CPR procedures until medical
help arrives and takes over.
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.
