A/P22P-6(V)2 and A/P22P-6A(V)2 Antiexposure Assemblies

The A/P22P-6(V)2 and the A/P22P-6A(V)2 antiexposure assemblies (fig. 4-5) are continuous wear assemblies designed to keep the wearer dry. The complete assemblies provide protection from the thermal effects of cold water immersion in the event of emergency overwater bailout. The assemblies differ only in the type of liner that is worn. The A/P22P-6(V)2 assembly uses the CWU-23/P liner, and the A/P22P-6A(V)2 assembly uses the CWU-72P liner. Table 4-2 lists the components that make up the A/P22P-6(V)2 and the A/P22P-6A(V)2 antiexposure assemblies.

The A/P22P-6(V)2 or the A/P22P-6A(V)2 antiexposure assembly should be worn by aircrew members for flight operations in accordance with the climatic and operational requirements established by the NATOPS General Flight and Operational Instructions Manual, OPNAVINST 3710.7 series.

The A/P22P-6(V)2 and the A/P22P-6A(V)2 antiexposure assemblies are intended to provide the aircrew member with a lightweight coverall assembly that allows for the performance of all required flight operations without restricting any body movements. The coveralls are moisture/ vapor permeable to prevent excessive buildup of body heat. In the event of immersion in water, the suit fabrics will not allow water to enter, keeping the wearer dry. All components of the assembly must be worn to achieve the greatest level of exposure protection.

The A/P22P-6(V)2 and the A/P22P-6A(V)2 antiexposure assemblies should be properly sized to the aircrew member based on his height, weight, and chest measurements. You would determine the chest circumference by taking a tape measurement at nipple height with the aircrew member wearing one cold weather undershirt. Refer to the Aircrew Personal Protective Equipment Manual, NAVAIR 13-1-6.7, for proper sizes.

CWU-23/P LINER. The CWU-23/P liner (fig. 4-6) is a one-piece garment that is supplied in 12 sizes. The liner is worn directly under the CWU-62/P antiexposure coverall, and over the recommended underclothing. The liner provides

an inner layer of 100% cotton and an outer layer of polypropylene netting.

Each sleeve ending has a coated stretch fabric insert to permit easy insertion of the hands and to reduce bulk. The leg endings are short enough to clear the tops of the flight boots, thereby eliminating bulk. They are notched at the front to allow standard wool or cotton socks to be pulled up over the liner legs, and to hold the liner legs in place when the CWU-62/P coverall is donned.

CWU-72/P LINER. The CWU-72/P liner (fig. 4-7) is a one-piece garment and is supplied in nine sizes. The liner is worn directly under the CWU-62/P coverall and over the recommended underclothing. The liner provides a layer of thermal protection, and is made of 100% olefin microfiber thermal insulation sandwiched between two layers of high-temperature resistant Aramid fabric.

CWU-62/P ANTIEXPOSURE COVER-ALL.- The CWU-62/P antiexposure coverall (fig. 4-8) is a one-piece garment and is supplied in 12 sizes. The coverall should not be worn in direct contact with the skin. It is a lightweight coverall that prevents water from entering, but permits bodily produced moisture vapor to pass out, thus minimizing heat and moisture buildup. Proper maintenance is essential to the life and safety of this coverall, as well as proper sizing and fitting. The neck seal and wrist seals are manufactured from natural rubber and are flocked on both sides. The entrance opening and the relief portal are sealed with a water and pressure-sealing slide fastener.

To fit the CWU-62/P coverall, the neck and wrist seals may be trimmed at the initial fitting, but the seals tend to adjust to the aircrew member after a short period of time. If no excessive seal restriction exists, and the seal fit is acceptable to the aircrew member, the seals should be left as they are. Neck seals need to fit snugly and remain in direct contact with the neck through all normal head movements. Wrist seals must fit tightly enough to prevent water entry, but not tight enough to restrict blood flow. If seal sizing is required, proceed as follows:

CAUTION

DO NOT USE A BALL-POINT PEN OR LEAD PENCIL TO MARK THE COVERALL MATERIAL. USE ONLY TAILOR'S CHALK OR A CHINA MARKING PENCIL.

1. If neck seal trimming is necessary, mark a line around the circumference of the neck opening. Trimming increments should not be more than one-eighth inch at a time.

2. Carefully cut along this line with a sharp pair of scissors.

3. Trim the wrist seals in the same way as the neck seal, except the trimming increments must not exceed one-third inch at a time.

4. After trimming the seals, have the aircrew member put on the coveralls to determine the seal restriction and the water-sealing characteristics. If any adjustments are necessary, you must repeat steps 1 through 3.
