Boating Safety - Section B
W. Maintenance - Ventilation Systems
Boats are equipped with ventilation systems to
eliminate gasoline vapors. Blowers and fans may also
be provided for ventilation and to mitigate the migra-
tion of CO into occupied compartments. Attention
should be paid to the following:
1. Keeping ventilation intakes clear of debris
2. Replacing damaged hardware
3. Maintaining the integrity of the ducting material
and its connections
4. Ensuring that position of ducting intake is not
obstructed or restricted, collapsed, kinked,
or crushed.
5. Eliminating sags in ducting that can form
a water trap
6. Checking hangers and other supports
7. Ensuring blower/fan is operational
8. Ensuring that airflow is present at discharge
9. Inspecting wiring to equipment
X. Maintenance - Bulkhead and Deck Integrity
1. Seal all visible openings (e.g., cracks, crevices,
holes, including openings around wiring and
piping runs) in bulkheads and decks that separate
machinery compartments from occupied compart-
ments. These openings can permit migration of
CO vapors.
2. Check gaskets and sealing surfaces on hatches,
doors, and access panels.
Y. Maintenance - Air Conditioning Systems
These systems can be a source of CO ingress
and migration of CO vapors.
1. Keep grilles and filters clean.
2. Seal bulkhead voids and openings at wiring and
piping runs in return air ducting, plenums, and air
handling equipment enclosures, especially those
adjacent to machinery compartment bulkheads.
3. Check that water traps and condensate drains
are present. These may be in the form of a double
loop in the drain line or prefabricated p-traps. Any
drain that discharges below the waterline when the
boat is underway is sealed, by virtue of its design,
against CO intrusion.
Z. Maintenance - Liquid Drains
Sink, shower and condensate drains can be a source
of CO ingress. Ensure that water traps are present
and contain fluid. These traps may be in the form of
a double loop in the drain line or prefabricated p-traps.
Any drain that terminates below the waterline is, by
virtue of its design, sealed against CO intrusion.
Some drains that are below the waterline when boat
is underway will be above the waterline when the
boat is at rest. The location of drains, relative to the
waterline, can be affected by the dynamics of boat
motion (i.e., underway or at rest).
AA. Carbon Monoxide Detection Systems
Four Winns has included three CO detectors as a
standard feature. The CO detectors are located in the
forward master stateroom, the main cabin/salon and
the mid cabin stateroom. Read the manufacturer’s
manual included in your owner’ packet regarding CO
monitor operation, testing and maintenance proce-
dures.
Unit should be cleaned weekly without the use
of solvents. Cleaning solvents and oils can
cause the alarm to stop functioning. Test the
alarm if it has come in contact with any
cleaning solvents or any condition that may
cause the alarm to stop working.
Never disarm a CO detector. If a CO detector
alarms, immediately ventilate the area and
check passengers for symptoms of CO
intoxication. See your Four Winns dealer for
assistance in diagnosing the cause for the
alarm.
