Life-saving appliances
Life-saving appliances are those appliances that protect human life at sea. The devices are documented as part of the International Convention for the Safety of Life at Sea, or SOLAS Convention.

Types  
In the SOLAS Convention and other maritime related standards, the safety of human life is paramount. Ships and other watercraft carry life saving appliances including lifeboats, lifebuoys, life-jackets, life raft and many others. Passengers and crew are informed of their availability in case of emergency. Life-saving appliances are mandatory as per chapter 3 of the SOLAS Convention. The International Life-Saving Appliance (LSA) Code gives specific technical requirements for the manufacture, maintenance and record keeping of life-saving appliances. The number and type of life-saving appliances differ from vessel to vessel, and the code gives a minimum requirement to comply in order to make a ship seaworthy.
