A life jacket is a tool designed to support a person on the water. Has a bright orange color, filled with either air or foam. The life jacket must meet the following requirements of GOST-22336-77: Positive buoyancy (9 or 20 kg, depending on the size); The strength of the belt is 240-320 kg per break; Ability to maintain respiratory system at a level of 12 cm from water; Have reflective bands, search lights, whistle, etc. Each vessel must have one lifejacket for each crew member. MK SOLAS-74 makes the following requirements for lifejackets: The lifejacket should not sustain burning and melt after it has been completely swept by the flame for 2 seconds. The design of the lifejacket should be such that: a person could properly wear it without assistance for no more than 1 minute; it was comfortable to wear; in it it was possible to jump into the water from a height of at least 4.5 m without bodily injury and without any displacement or damage to the lifejacket. The lifejacket should have sufficient buoyancy and stability in fresh water in the absence of excitement in order to: maintain the mouth of a weak or unconscious person at a distance of at least 120 mm from the water so that the human body is tilted back at an angle of at least 20 ° and not more than 50 ° from its vertical position; turn the body of a person who has lost consciousness in water from any position to such that his mouth is above the water for no more than 5 seconds. the buoyancy of the lifejacket should not decrease by more than 5% after submerging it in fresh water for 24 hours. Each lifejacket should be equipped with a whistle, securely attached to it with a cord.
