The FSS Code (International Code for Fire Safety Systems) is a set of international treaties organized by the International Maritime Organization (IMO) under the SOLAS Convention. It is designed to reduce the risk of fire and aid in emergency response aboard ships. The code is mandatory under SOLAS Chapter II-2, which concerns construction, fire protection, fire detection, and fire extinction.
Background
The FSS Code was adopted by IMO Resolution MSC.98(73) and made mandatory through Resolution MSC.99(73), which revised Chapter II-2 of the SOLAS Convention. The code provides detailed technical specifications for various fire safety systems installed on ships.
Components
The FSS Code covers the following fire safety systems:
- Fire extinguishers — specifications for portable extinguishers
- Fixed gas fire extinguishing systems
- Fixed foam fire extinguishing systems
- Fixed pressure water and water spraying systems
- Automatic sprinkler, fire detection, and fire alarm systems
- Fixed emergency fire pumps
- Fixed deck foam systems
- Inert gas systems
History
The development of the FSS Code is rooted in a series of maritime disasters that prompted successive revisions to fire safety regulations:
- 1914 and 1929 SOLAS Conventions — adopted after the sinking of the RMS Titanic (1912)
- 1948 and 1960 SOLAS Conventions — adopted after the Morro Castle sinking (1934)
- 1974 SOLAS Convention — introduced Chapter II-2 on fire protection, detection, and extinction
- 1981 revision — a comprehensive rewrite of Chapter II-2
- 1990 — the MS Scandinavian Star disaster (159 fatalities) led to amendments addressing fire safety measures for existing passenger ships, adopted in London on 10 April 1992
- 1996 — the International Code for Application of Fire Test Procedures was adopted in London on 5 December 1996, establishing laboratory testing standards for fire safety systems
- 2012 — IMO Resolution MSC.327(90) (25 May 2012) and Resolution MSC.339(91) (30 November 2012) introduced further amendments to the FSS Code
Current Edition
The FSS Code is regularly updated. The most recent consolidated edition includes amendments adopted by the IMO Maritime Safety Committee, with the latest amendments entering into force on 1 January 2026.
