The Navy standard hose for dewatering and firefighting
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.
The 2 ½-inch by 50-foot cotton and nylon hose line also
is standard for supplying educators and the discharge
hose for electrical submersible pumps. The 4 inch hose
is the standard dischage hose for the educator. |
