Purpose:
The twin-chamber life jacket s designed for constant.
Wear by personnel working under emergency conditions or in danger of falling overboard. When fully inflated the life jacket is positively self-righting, and it will keep the head of the wearer, conscious or unconscious, above water.
Describtion
*The life jacket manufactured from two-ply yellow nylon cloth rubberized with neoprene.
It held in a compact nylon pouch supported by a strong waist belt.
In an emergency, the life jacket’s upper section easily
removed from the pouch,
Pulled over the wearer’s head, and inflated.
*Identical, independent buoyancy chambers assure
floating. If one chamber damaged, the other can be
inflated to full life jacket capacity. This feature prompted
the Israeli Navy’s decision to make the life jacket
standard equipment.
*The buoyancy chamber inflated by a carbon-dioxide
cylinder, which is Screwed into a manually operated,
streamlined head.
*oral inflation maximizes life jacket
buoyancy during mechanism failure.
 Two oral-inflation tubes attached to the buoyancy chambers, with inflation valves near the wearer’s mouth. Each valve is opened and closed by depressing and releasing the mouthpiece, which locked by a safety nut.
 * A water-actuated battery with light assembly operates immediately upon immersion in water.
The light lasts for six hours, aiding survival and visibility in the dark.
* A non-corrosive plastic whistle provided to attract rescuers. A nylon cord attaches
the whistle to an accessible elastic loop on the front of the buoyancy chamber.
 *The pouch constructed from navy blue nylon.
The pouch flap is closed by two press fasteners and Velcro straps.
The waist belt, made of 1.75 inch wide nylon webbing, passes through two reinforced openings to support the pouch.
A slide adjuster fits the waist belt to the wearer. A One-inch wide, navy blue lifting loop on the waist belt allows the wearer to be lifted out of the water.
