42C System Operations - 31
The
fi
re extinguishers shipped with your
42C
should be mounted in a readily ac-
cessible location away from the engine
compartment, but in a relative position to
potential
fi
re hazards, such as the Galley.
The
fi
re extinguishers should be mounted
within plain view and all passengers on
board should be familiar with their location
and operation before departing your dock.
Maintenance of your portable
fi
re extin-
guishers should consist of periodic clean-
ing of the canisters and making certain
they are easily seen and readily acces-
sible. Periodically examine the gauge on
each
fi
re extinguisher to be sure they are
fully charged. If the gauge indicates the
fi
re extinguisher is not fully charged, con-
tact your Silverton Dealer for replacement.
DO NOT test the charge of your portable
fi
re extinguishers by operation of them; it
will discharge them unnecessarily.
REFER to the operating instructions dis-
played on the
fi
re extinguisher canisters
for a detailed description of their operation
and use.
PORTABLE FIRE
EXTINGUISHER SYSTEM
As a yacht owner or operator, you have
the responsibility of having the required
quantity of United States Coast Guard ap-
proved portable
fi
re extinguishers aboard
at all times, except during storage. The
portable
fi
re extinguishers must be opera-
tional and of the proper classi
fi
cation.
The classi
fi
cation of portable
fi
re extin-
guishers and their appropriate use is as
follows:
CLASS “A”
“Fires in ordinary combustible materials,
such as wood, paper and cloth, where the
quenching-cooling effect of quantities of
water or high water content solution cools
the burning material below the ignition
temperature.”
CLASS “B”
“Fires in
fl
ammable petroleum products
or other
fl
ammable liquids, greases, etc.,
where the blanketing-smothering effect of
oxygen-excluding media is most effective.”
CLASS “C”
“Fires involving electrical equipment where
the electrical conductivity of the extin-
guishing media is the
fi
rst consideration.”
Your
42C
is equipped with two (2) Class
B/C portable, handheld
fi
re extinguish-
ers. Class B/C
fi
re extinguishers will
effectively
fi
ght
fi
res of the Class “B” and
Class “C” type. The Class B/C portable
fi
re extinguisher contains pressurized dry
powder, which when released, will leave
a powder residue that smothers the
fi
re
and removes its source of oxygen. Once
the source of oxygen is removed, the
fi
re
cannot continue to burn and it will be ex-
tinguished.
