OPERATION OF AUXILIARY EQUIPMENT.
2-5.1 Fire Extinguishers. There are four fire extinguishers (three CO2, one dry chemical type) aboard the vessel.
There is one in the lazarette, and two in the engine room. The dry chemical type is stored in the pilothouse. The
operating procedure follows:
a.
Carry the extinguisher (1) in an upright position and approach the fire as closely as the heat permits.
b.
Remove the locking pin (2) from the valve (3).
c.
Grasp the hose (4).
d.
Squeeze the release lever (5) and at the same time direct the carbon dioxide/dry chemical flow toward the
base of the fire with a sweeping motion.
e.
Fight the fire from the windward side so the wind will blow the heat away from the operator.
f.
In fighting fire in electrical equipment, or on a bulkhead, direct the discharge at the bottom of the flaming
area. Move the horn slowly from side-to-side and follow the receding flames upward.
NOTE
The valve can be opened and closed repeatedly without loss from leakage.
g.
Release the lever (5) to close the valve (3) as soon as conditions permit. Continue to open and close the
valve as necessary.
h.
When continuous operation is desired, the D-yoke ring on the carrying handle may be slipped over the
operating handle when the handle is depressed.
