Marine Fire-Fighting Systems: SOLAS Requirements and Equipment Guide

A fire at sea is far more dangerous than one ashore: there is no fire brigade, escape is limited, and the ship must fight it with its own means. That is why marine fire-fighting systems are among the most critical elements of maritime safety and are strictly regulated by the international SOLAS convention. This guide explains shipboard fire-fighting systems, mandatory equipment and maintenance requirements.

SOLAS and Fire Safety

Chapter II-2 of SOLAS — "Fire Protection, Fire Detection and Fire Extinction" — sets the fire-safety standards for ships, covering structural fire protection, detection/alarm systems and extinguishing equipment. Commercial vessels must meet these requirements and document them during Port State Control (PSC) inspections.

Types of Shipboard Fire-Fighting Systems

• Fixed CO2 systems: for enclosed spaces such as engine rooms and cargo holds; smother the fire by displacing oxygen.
• Foam systems: effective for liquid-fuel fires, especially on tankers.
• Water mist / sprinkler systems: in accommodation and machinery spaces, cooling and smothering with fine water droplets.
• Fire main and hoses: fed by seawater pumps, with deck nozzles and hoses.
• Portable extinguishers: for manual response — powder, CO2 and foam types.

Mandatory Fire Equipment

Key SOLAS items include portable extinguishers, fireman's outfits (fire suit, SCBA breathing apparatus), fire blankets, the international shore connection, fire detectors and safety signs. Many of these are identified by IMPA codes (notably section 05, Safety Equipment).

Maintenance and Servicing

Fire equipment must be regularly tested and serviced. Portable extinguishers are periodically weighed and pressure-checked; SCBA cylinders undergo refill and hydrostatic testing; fixed systems require annual certified service. Missing or overdue equipment can lead to detention of the vessel.

Sourcing Fire Equipment

Search extinguishers, SCBA, detectors and spares by IMPA code on e-ShipSupply and source them through supplier listings. Since certification and service dates are critical for safety equipment, confirm these details with the supplier.

Frequently Asked Questions

Which fire-fighting systems are mandatory on ships?

Depending on ship type and tonnage: a fixed extinguishing system (usually CO2 for the engine room), fire main and hoses, portable extinguishers, fireman's outfits and a fire detection system are required under SOLAS.

Can fire equipment be found by IMPA code?

Yes. Safety equipment is mostly coded under IMPA section 05; find products via the IMPA search page.
