On board ships, Life-Saving Appliances (LSA) and Fire-Fighting Appliances (FFA) are critical for ensuring the safety of the crew and passengers in emergencies. These items are regulated by international conventions, such as the International Maritime Organization (IMO), specifically under the SOLAS (Safety of Life at Sea) convention.

The LSA items ensure that people can survive in emergency situations, such as ship abandonment or drowning, while the FFA items ensure that fires are promptly detected and extinguished to protect lives and property. The selection, installation, and regular maintenance of these systems are required by SOLAS and other maritime regulations to comply with international safety standards and ensure the well-being of everyone aboard.
