Fixed Halon Fire Extinguishing Installation Sign

Fixed Halon Fire Extinguishing Installation Sign – IMO Fire Control Symbol FS0160

The Fixed Halon Fire Extinguishing Installation sign is a mandatory IMO fire control symbol used to mark the location of a vessel’s fixed halon fire-extinguishing system storage bank. Recognised under IMO Resolution A.654(16) and reproduced to ISO 17631, this pictogram allows crew, surveyors, and shore-based emergency responders to identify the installation instantly, regardless of the language they speak.

The symbol depicts a horizontal cylindrical storage vessel with a light brown band across its centre, labelled “H” above, denoting the fixed halon fire-extinguishing installation specifically (as distinct from the equivalent fixed installation symbols used for CO2, nitrogen, or foam systems). This design forms part of the internationally standardised library of fire control symbols found on fire control plans, damage control plans, and general arrangement drawings across commercial vessels, offshore installations, and naval ships.

Why the Fixed Halon Installation Location Matters

A fixed halon fire-extinguishing installation stores halon gas in a dedicated bottle room or storage bank, ready to flood a protected machinery space or cargo hold to interrupt the chemical chain reaction of combustion and rapidly extinguish a fire. Because the installation itself, and not just its remote release point, must be clearly identifiable, this sign is fixed directly at or near the storage bank so crew, surveyors, and emergency responders can immediately locate the halon supply during an inspection, drill, or genuine emergency.

Because rapid, unambiguous identification of fixed fire-extinguishing installations is so important during a fire emergency, SOLAS Chapter II-2 and the Fire Safety Systems Code require clear signage marking their location so crew unfamiliar with a particular vessel, relief officers, and visiting surveyors can find them without delay. This sign is typically mounted directly on or beside the halon room bulkhead or storage bank enclosure, and is also reproduced on the fire control plan posted at the gangway and bridge.

Compliance and Certification

This Fixed Halon Fire Extinguishing Installation sign is manufactured to comply fully with IMO Resolution A.654(16) and ISO 17631 symbol requirements, ensuring the pictogram, colour scheme, and proportions match the standard expected during port state control inspections, classification society surveys, and SOLAS compliance audits. Non-standard or incorrectly proportioned signage is a common source of survey deficiencies, so every FS0160 sign is checked against the current IMO symbol register before it leaves our warehouse.

Manufactured from durable photoluminescent, self-adhesive vinyl, this sign charges under normal ambient lighting and glows for an extended period in the dark, ensuring the halon installation remains identifiable even during a blackout or power failure. This self-luminous performance is especially valuable in machinery spaces and dedicated bottle rooms where visibility can drop sharply during a fire or smoke event.

Installation Recommendations

For best results, mount this sign at eye level directly on or beside the halon storage bank enclosure or bottle room door, in a position that stays visible and unobstructed by cabling, fittings, or nearby equipment. Clean the mounting surface thoroughly to remove any dust, oil, or moisture before applying the self-adhesive backing, ensuring a permanent bond that will hold up to the conditions typical of a machinery space or dedicated bottle room.

Vessels undergoing a fire control plan update, newbuild fit-out, or SOLAS compliance retrofit should ensure this sign is included alongside the complete suite of IMO fire control symbols so that the printed fire control plan matches the physical signage installed throughout the ship. Surveyors routinely cross-check the fire control plan against signage actually fitted onboard, making consistency between the two a key focus area during flag state and classification inspections.

Key features of this Fixed Halon Fire Extinguishing Installation sign include:

• Complies with IMO Resolution A.654(16) and ISO 17631 fire control symbol standards
• Photoluminescent vinyl construction for visibility during power loss or low-light conditions
• Self-adhesive backing for fast, permanent installation on panels and bulkheads
• Waterproof and saltwater resistant for long-term use throughout the vessel
• Matches the standard pictogram used fleet-wide on fire control plans for consistent crew recognition
