In this final paper, the methods of detection and extinguishing fires on passenger ships will be described. Damages and losses on ships after the fire caused the need for a systematic arrangement of safety on board. Fire safety requirements on board are defined by the International Convention on Safety of Life at Sea (SOLAS), and their rules and content are continuously updated and improved. Fire extinguishing agents on board do not differ too much from those on land, and the most well-known are water, foam, carbon dioxide and other gases, and how and in which cases a particular agent is used depends on the type of fire. Each ship, depending on its purpose, has built-in specific ship systems for extinguishing fires and detection and alarm systems. In order to increase the safety and reliability of the fire protection system, new techniques and technologies have been developed that are increasingly used today. Today, fire alarm systems are integrated into the ship's system to establish centralization. The paper specifically analyzes passenger evacuation methods in case of fire, including a case study.
