The Navy standard hose for firefighting topside since
the 1940s has been the 2 ½-inch by 50-foot cotton and
nylon hose line. It is a required outfitting for topside
fire stations. Besides being connected to fire plugs,
the fire hose can be connected to the 2 ½-inch outlet on
P-500 and P-250 pumps. Using a wye-gate, the hose run
can be extended with two 1 ½-inch hose lines, with an
all purpose nozzle (APN) attached at the end. An APN
with a 4- or 10-foot applicator inserted is attached for
specific functions and requirements in firefighting. An
in-line eductor can be attached with an NPU in the hose
line, with a mechanical foam nozzle attached if
required, for an oil or fuel oil fire. While the 2
½-inch hose line could be run for use below decks, the
Navy standard hose for firefighting below decks is the 1
½-inch by 50-foot cotton hose line and is a required
outfitting for all below deck fire stations. Some
locations below decks have a 1 ½-inch fireplug; in those
installations, the 1 ½-inch hose is connected directly
to the fireplug. |
