G. Inspection
Look.and.listen.for.leaks.in.the.exhaust.systems.of.
both.the.generator.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.plumbing.
and.cableways.and.exhaust.system.doors,.
hatches,.and.access.panels.are.minimized.to.
reduce.the.opportunity.for.CO.to.enter.the.accom-

Boating Safety - Section B
The following are examples of possible
situations where carbon monoxide can
accumulate within your boat while docked,
anchored, or underway. 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.
concentrations.of.CO.can.accumulate.when.a.boat,.
generator.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..
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.equipment.
for.extended.periods.under.these.conditions...

and other confined spaces.
Be.aware.that.cockpit.and.deck.drains.can.be.a.
source.of.CO.ingress.into.boats,.especially.boats.with.
