what is Marine Life Saving Appliances

The use of on-board equipment by the crew of a ship to rescue a person overboard or, in the event of a shipwreck, the abandonment of the ship in accordance with a life-saving deployment for self-rescue. Broadly speaking, it also includes rescuing other ships or accepting external assistance. The purpose is to protect the safety of life on board (SOLAS).
Ship life-saving equipment is divided into: individual life-saving appliances and collective life-saving equipment.

Marine Life Saving Devices: Life Smoke

Smoke Signal refers to all kinds of pyrotechnics that can emit smoke, sound and light for use as a call for help signal when the ship is in distress.

According to the signal classification, it is divided into flame type and smoke type.

Classified according to the release method:

  1. RPF type-Rocket Parachute Flame Signal
  2. HF type – handheld flame signal
  3. BSS type – floating smoke signal
