boat to maximize the dispersion of CO.

We cannot identify or describe every possible variable or
combination of variables, you must continually observe
passengers for symptoms or Carbon Monoxide intoxica-
tion and be aware of the many possibilities of Carbon
Monoxide accumulation. For instance, poorly maintained
hoses and hose connections on the generator or engine
exhaust system(s) can permit Carbon Monoxide to escape
into the interior of your boat. Therefore, the exhaust sys-
tem must be periodically examined and maintained in
order to ensure its integrity. Moreover, all accommodation
spaces constantly require proper ventilation.

4.2.8 Preventative Maintenance

Frequent inspections and proper maintenance of the
engine, and exhaust system, as well as, other various
areas of your boat are critical in preventing the accumula-
tion of Carbon Monoxide. It is the owner’s responsibility
to make sure the entire boat is inspected and maintained
against CO.

The exhaust systems of your engines and generator are
under constant attack from salt water, gasses, vibra-
tion, and normal wear. Inspect every exhaust system
component often. Start with a visual inspection. Check
each joint for discoloration, carbon buildup, stains, water
leaks, or other signs of damage. Inspect all metal parts
for corrosion, discoloration, or flaking. Check that all
hose clamps are in good condition and properly tight-
ened. Carefully inspect all exhaust and cooling hoses for
signs of wear, dry rot, cracking, discoloration, chafing, or
swelling. If any of these conditions exist, have the entire
system inspected and corrected by a qualified technician
before starting the engines or generator.

Next, start each engine and generator one at a time.

Follow the full run of the exhaust system, listening and
looking for leaks. While doing this, make sure there is
adequate ventilation and that your CO detector is on.

Other items to inspect are as follows: If your boat has
access panels, check that the access panels around
the engine and exhaust are in place and fit snugly to
minimize the opportunity for CO to enter the cabin. There
should be no large openings where CO could enter the
cabin. Ensure that all ventilation systems are in good
working order and are not blocked or punctured. Check
all sink drains to assure that they have a good water trap
to prevent CO from coming in from the outside.

Finally, because poorly running engines produce exces-
sive  CO, make sure engines and generators are tuned
up.  They  should run smoothly and not produce  black
smoke. The spark plugs  (gas engines) and ignition sys-
tems should be maintained regularly, and the fuel system
and air filters should be in good order.

4.2.9 Carbon Monoxide Detectors

If  you carefully avoid potential CO accumulation and
maintain  your systems properly,  you have made great
strides towards protecting  yourself and others from the
dangers of  Carbon Monoxide. We have assisted you in
your endeavor by providing  CO detectors in each living
area aboard your boat. We use only those CO detectors
that are UL approved for marine use. RV and residen-
tial models won’t withstand the elements of the boating
environment. Most CO detectors require specific main-
tenance procedures to remain accurate and functional.
Follow the  manufacturer’s instructions  for the  use  and
maintenance of the CO detectors.

it's strong recommended that you change CO and Smoke
alarm batteries when changing the clocks for Daylight-
Saving Time.

Replace Smoke Alarms every 10 years

and

replace Carbon Monoxide (CO) alarm every 5

years

since the sensors in these devices can degrade

because of environmental contamination and from age.
In addition to replacing batteries in smoke alarms at
least once every year. Always make sure the followings:

Smoke/CO alarms should be tested month-

ly to make sure they are working in your boat.

Batteries should be changed once a year, when-

changing the time on clocks of your boat.

“A working smoke alarm can save lives. It’s that simple
and that important,”

hazards.

4.2.10 Carbon Monoxide Review

Everyone is at risk for Carbon Monoxide poisoning!
Particularly sensitive are children, pregnant women, the
elderly, and people with lung disease, heart disease, or
anemia!
