Highest consideration factor is given to human life at sea while dealing with any type of emergency and life saving appliances plays an important role in saving lives in all types of emergency situation.
A ship is assigned with different types of life saving appliances for various emergency situations and their operating and maintenance procedures must be well known to the ship’s staff.
One such life saving appliance which is used in almost all kinds of emergencies is the Life jacket or life vest. The details for construction and operating requirements are given in SOLAS chapter II under LSA code which was recently amended in July 2010.
What is life jacket?
Life jacket is a sleeveless jacket made up of buoyant or inflatable material used to keep human body afloat in water.
Two popular types of life jackets used onboard are:
- Inflatable life jacket: This jacket needs inflation for buoyancy and is automatically inflated when immersed in water. It normally consists of two different buoyancy compartments.
- Non inflatable life jacket: These jackets are fitted with buoyant materials and they don’t need to inflate.
How many life jackets should be there on a ship?
On Passenger Ships
- There must be a life jacket for every person onboard ship.
- Life jacket for each child or 10 % of the total number of passenger which ever is higher.
On Cargo ships
- There must be a life jacket for all the crew and their families, if onboard.
- Since officers carry their family with them, infant life jacket must be provided in cargo ships.
The number of life jackets must be carried in excess as in case of damage to any, it can be replaced with spare one.
