11、ll be capable of righting, within 5 s, an unconscious person who has been forced into the water in a face down attitude. The life preserver shall provide lateral and occipital support to the wearers head such that the mouth of an unconscious adult is held well clear of the water line with the trunk
12、of the body inclined backward from the vertical at a minimum of 30. 3.2.2 After being forced into a face-down attitude, and upon immediate return to the face-up attitude, the life preserver or flotation device shall not permit the unconscious wearer to return to the face-down attitude. 3.2.3 Life pr
13、eservers for infants must demonstrate a capability to support the body in a stable attitude with the mouth and nose supported well clear of the surface of the water. Bassinets or flotation cots should demonstrate stability and seaworthiness and be capable of protecting the infants respiratory system
14、 from inspiration of water and drowning due to swell or wave action. 3.2.4 A tether line, not less than 72 in long, shall be attached to infant life preservers at a point that tension will not adversely change the buoyancy attitude when the line is attached to an adult in the water. 3.3 Donning of t
15、he Life Preserver: 3.3.1 The means of donning the life preserver shall be self-evident to the extent that the device may be readily donned or placed upon another user by an average adult assisted by pictorial instructions only. (See 3.11.1) 3.3.2 It shall be possible for an unassisted adult to don h

19、 designed so as to allow free, unobstructed SAE ARPx1354A 91 = 7943725 O500299 O SA ARP1354 Revision A 3.4.3 The life preserver shall be designed so as not to restrict blood circulation, especially in the areas of the neck, armpits, and groin. 3.4.4 The life preserver shall not restrict breathing. 3
20、.4.5 The preserver shall be designed so as to allow for adjustment for fit and comfort while the user is in the water. 3.4.6 The life preserver shall be constructed to allow a maximum degree of head and neck movement consistent with the requirements of 3.2.1 regarding flotation attitude. 3.5 Freedom
21、 of Movement: 3.5.1 The adult and the adult/child life preserver shall be designed so that the user can swim, render assistance to others, and board a life raft or slide/raft. 3.5.2 The adult and the adult/child life preserver shall provide the user with sufficient freedom or arm movement to carry o
22、r support an infant in the water. 3.6 General Configuration: 3.6.1 The life preserver shall have at least two independent flotation chambers each of whlch Is provided with a mechanical and an oral inflation means. When elther of these chambers is inflated and the remainlng chamber deflated, the infl
23、ated chamber shall be capable of supporting the wearer with mouth and nose clear of the water line. 3.6.2 All hardware and equipment attached to the life preserver shall be located and padded so as to preclude the possibility of chafing the material of the preserver either in the packaged or in-use
24、condition. 3.6.3 It shall be possible for the adult or child user to jump feet first from a height of 5 ft (1.52 m) into the water wearing a fully inflated or deflated life preserver without injury to user caused by the preserver, and without damage to or loss of the life preserver. 3.6.4 Once orall
25、y inflated, a life preserver chamber will not burst upon subsequent discharge of the gas inflation system. 3.6.5 The infant flotation device tether (see 3.2.4) shall be of sufficient strength to permit lowering of the infant into the water to the proper buoyancy attitude. 3.7 Mechanical Inflation Sy

Positioning of the inflation means shall be such that it can be 3.7.3 The mating of the inflation system to the material of the preserver shall be constructed so as to withstand static force of 250 lbf (11.12 N). 3.8 Oral Inflation System: 3.8.1 3.8.2 3.8.3 3.8.4 Each chamber shall be equipped w
28、ith an oral-inflation device fitted with a nonreturn valve that will permit the user to fully inflate each chamber. Once the life jacket is orally inflated, the oral inflation device should return to such a position that it does not produce eye or other facial injuries during a jump into water as sp
29、ecified in 3.6.3. The inflation device shall be located so as to be easily found and readily accessible to the user in and out of the water. The inflation device shall incorporate some means of quickly deflating each chamber. This deflation operation shall be such that it requires a positive act by
30、the user; i.e., it cannot happen inadvertently. The joint between the oral inflation valve and the flotation chamber may not fail when a 100-lb tensile load is applied for at least 3 s outwardly from and perpendicular to the surface of the flotation chamber at the point of valve attachment. 3.9 Colo
31、r: 3.9.1 The color of the life preserver shall be an approved international rescue color, except as modified in consideration of the area in which a particular air carrier operates. 3.9.2 Crew life preservers shall be readily distinguishable from passenger life preservers. 3.10 Equipment: 3.10.1 All
32、 life preservers shall incorporate a survivor locator light which meets the requirement of TSO-C85 and is located in such a manner as to provide maximum practical conspicuity in the water. If the survivor locator light is not automatically activated, the means for activation shall be readily accessi
33、ble and self-evident. For increased conspicuity and enhancement of the effect4veness of searchlights or other directed light sources, retroreflective materials or devices may be affixed to the life preserver in accordance with 3.10.3. 3.10.2 Crew life preservers shall incorporate a whistle or other
