Water rescue equipment is specialized gear used for water rescue, primarily including life jackets, life rafts, rescue radios, marine self-defense weapons, and shark repellents. It is widely used in aviation, maritime, and water emergency rescue. This equipment must be equipped according to the passenger capacity of the location. Airports near waterways must be equipped with basic rescue equipment based on the maximum passenger capacity of their largest aircraft and sign support agreements with relevant units.
Life jackets are made of polyethylene foam or inflatable materials, with a buoyancy loss of less than 5%. They are equipped with reflective markings for easy identification during search and rescue. Inflatable life jackets use carbon dioxide cylinders to create an inverted U-shaped buoyancy support, keeping the victim's head above water. Life rafts are divided into slide-type and inflatable types. Slide-type life rafts are equipped with emergency positioning transmitters that automatically send distress signals upon contact with water and can inflate and deploy. Life rings have an orange-red exterior, a minimum buoyancy of 8 kg, and are equipped with a floating lifeline; some models also have self-illuminating float lights. The communication equipment includes navigation and positioning systems such as GPS and VHF radios, which together with the rescue radios form an emergency communication network.
