LPU-34/P LPFC
WARNING
When using the manual inflation tubes, do not inhale
CO2 that may be present (under pressure) in the flotation
cells. Severe lung damage may occur.
The inflation shell assembly contains two inflatable bladders. The
LPU-34/P LPFC is inflated by pulling the beaded handles on each
side of the exterior cover. Each beaded handle is connected by a
lanyard to the actuating lever of an inflation device. Pulling the
handles initiates zipper separation on the exterior cover and causes
the CO2 cylinder to be punctured, inflating the bladders. The zipper
on the exterior cover continues to separate as the bladders inflate to
provide head-out-of-water buoyancy.
In an emergency situation, the oral inflation tubes may be used to top
off the inflated bladders, maintain inflation in a leaky bladder, or
inflate a bladder if an inflation device malfunctions. The oral inflation
tube may also be used to inflate the bladders during an inspection test
or to evacuate air to perform packing.
