Portable Foam Applicator Unit Sign

Portable Foam Applicator Unit Sign – IMO Fire Control Symbol FS0191

The Portable Foam Applicator Unit sign is a mandatory IMO fire control symbol used to mark the location of a portable foam applicator unit, on board a vessel. Recognised under IMO Resolution A.654(16) and reproduced to ISO 17631, this pictogram allows crew, surveyors, and shore-based emergency responders to identify a portable foam applicator unit position instantly, regardless of the language they speak.

The symbol depicts a red and yellow banded canister with an integral hose and applicator nozzle curving up and over the top of the unit, denoting a self-contained foam-generating appliance that is carried and operated by hand rather than a fixed installation. 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 Portable Foam Applicator Unit Location Matters

A portable foam applicator unit is a self-contained appliance that premixes foam concentrate with water and air to produce a foam blanket, ideal for smothering small spill fires and flammable liquid fires in galleys, paint lockers, and machinery spaces where a fixed foam system is not installed. Because these units are typically stored in a bracket near the risk area they protect, crew need a clear, instantly recognisable sign to locate the nearest portable foam applicator unit quickly during a fire emergency or drill.

Because rapid, unambiguous identification of fixed fire-fighting equipment is so important during a fire emergency, SOLAS Chapter II-2 and the Fire Safety Systems Code require clear signage marking the position of every portable extinguishing appliance, including foam applicator units, so crew unfamiliar with a particular vessel, relief officers, and visiting surveyors can find them without delay. This sign is typically mounted directly above or beside the storage bracket for the unit, and is also reproduced on the fire control plan posted at the gangway and bridge.

Compliance and Certification

This Portable Foam Applicator Unit 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 FS0191 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 portable foam applicator unit location remains identifiable even during a blackout or power failure. This self-luminous performance is especially valuable in galleys and machinery spaces where visibility can drop sharply during a fire event.

Installation Recommendations

For best results, mount this sign at eye level directly above or beside the storage bracket or securing point for the unit, 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 galley or machinery space location.

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 Portable Foam Applicator Unit 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

This sign is a small but essential part of a compliant fire control plan. Every sign we supply is checked for compliance before dispatch.
