when victims are unaware of any side effects.
Low levels of carbon monoxide over an extended period of time can be just as lethal as high doses
over a short period. Therefore, low levels of carbon monoxide can cause the alarm to sound before
the occupants of the boat notice any symptoms of carbon monoxide poisoning. CO detectors are
very reliable and rarely sound false alarms. If the alarm sounds, always assume the hazard is real
and move persons who have been exposed to carbon monoxide into fresh air immediately. Never
disable the CO detector because you think the alarm may be false. Always contact the detector
manufacturer, the Pursuit Customer Relations Department or your local fire department for
assistance in finding and correcting the situation.
CO POISONING PRODUCES FLU-LIKE SYMPTOMS: WATERY AND ITCHY
EYES, HEADACHES AND FATIGUE. YOU CAN’T SEE IT AND YOU CAN’T
SMELL IT. IT’S AN INVISIBLE KILLER.
The following are symptoms which may signal exposure to CO: dizziness, flushed face, ears
ringing, headaches, tightness of chest or hyperventilation, drowsiness, fatigue or weakness,
inattention or confusion, lack of normal coordination, nausea and unconsciousness. The victim’s
skin also may turn red. A slight build-up of carbon monoxide in the human body over several hours
causes headache, nausea and other symptoms similar to food poisoning, motion sickness or the flu.
Anyone with these symptoms should immediately be moved to an area of fresh air. Have the victim
breath deeply and seek immediate medical attention. To learn more about CO poisoning, contact
your local health authorities.
In certain situations, boats can have a problem
due to the “station wagon effect” where en-
gine exhaust fumes are captured in the vessel
by the vacuum or low pressure area, usually
the cockpit, bridge deck and cabin, that can be
created by the forward speed of the boat.
Boats that are underway should close all aft
facing portholes, hatches and doors. The
forward facing deck hatches should be open
whenever possible to help pressurize the liv-
ing spaces of the boat. Sleeping, particularly
in aft cabins, should not be permitted while
underway. Proper ventilation should be main-
tained on the bridge deck by opening a forward window or windshield to drive fumes away from
the occupants. The canvas drop or aft curtain must be removed and the side curtains should be
opened or removed to increase air flow and maintain proper ventilation whenever the engines are
running.
