Placement and use of life jackets on water

Wearing a life jacket can provide a stable buoyancy for those who fall into the water, and can make the mouth and nose of the unconscious person out of the water. Life jackets on ships cannot be placed under the seats, they should be stored according to the following requirements:
(1) The life jackets of ordinary ships should be stored on the deck where they are clearly visible—easy to access and dry, and clearly marked there.
(2) The life jackets of the crew and passengers should be placed in a place of residence or easily accessible, generally placed near the beds of the crew or passengers, and cannot be locked in the closet.
3) Life jackets shall be affixed with the name plates assigned in the contingency deployment table, indicating the boat number and the location of the boat deck assembly and their duties.
(4) A schematic diagram of how to use life jackets should be posted on the ship at appropriate locations.
(5) If there are separate life jackets for adults and children on the passenger ship, the words "only for children" should be clearly written on both sides of the life jacket. The number should be 1/10 of the number of passengers (not the total number).

(6) Life jackets shall not be stored in damp, greasy or excessively hot places and shall not be locked. 

(7) Educate the crew and passengers not to use life jackets as pillows or cushions at will, so as to avoid the reduction of buoyancy after pressure.

(8) One whistle shall be provided for each lifejacket of an international sailing ship.
