Foam Nozzle Sign

Foam Nozzle Sign – IMO A.654(16) Fire Control Symbol FS0243

This Foam Nozzle sign identifies the location of a fixed foam-branch nozzle connection point, used to direct foam concentrate onto a flammable liquid fire from the vessel’s fixed or semi-fixed foam firefighting system. The pictogram shows the standardised red foam nozzle symbol with the letter “F”, matching exactly what appears on the vessel’s fire control plan for this location. As SKU FS0243 in the Fire Fighting Signs range, it is designed for permanent fixing beside foam nozzle connections in machinery spaces, cargo pump rooms, tank decks and other areas where flammable liquid fire risk is present.

A foam nozzle connection lets crew apply a foam blanket over a flammable liquid spill or fire quickly, cutting off the vapour supply that feeds the flames, which makes fast, confident location of every nozzle connection point critical during a genuine incident. Clear signage also supports routine fire equipment rounds, where crew confirm every foam nozzle connection remains accessible, undamaged and correctly matched to the vessel’s foam system layout. The photoluminescent background of this sign keeps the connection point identifiable during a blackout, exactly when foam application may be the only way to control a developing liquid fire.

Why Foam Nozzle Identification Matters

Crew responding to a flammable liquid fire need to reach the nearest foam nozzle connection without delay, since foam application is most effective when applied early, before the fire develops beyond first-response capability. Correctly signed nozzle points also support fire drills and equipment familiarisation, helping new crew learn the layout of the foam system across machinery spaces, pump rooms and open deck areas. This distinction matters particularly on tankers and vessels carrying flammable cargo, where multiple foam nozzle connections may be spread across a large deck area.

Compliance and Certification

This sign reproduces the fire control symbol set derived from IMO Resolution A.654(16) and continued under the current ISO 17631 standard for fire control plan graphics, matching what flag-state surveyors and classification societies expect to see identifying fixed and semi-fixed foam firefighting equipment. SOLAS Chapter II-2 sets requirements for foam fire-extinguishing systems protecting machinery spaces and cargo areas carrying flammable liquids, and correctly labelled foam nozzle connections are part of demonstrating that this equipment is genuinely in place during Port State Control inspections and class surveys. Fitting SKU FS0243 keeps your foam system signage matched to the fire control plan surveyors will reference.

Installation Recommendations

Fix this sign directly above or beside the foam nozzle connection point, using the pre-drilled fixing holes for a permanent mechanical fixing or the self-adhesive backing on smooth painted surfaces. In machinery spaces and open deck areas exposed to weather, vibration and oily residue, a screw or rivet fixing will outperform adhesive over the vessel’s operating life, and the sign should remain visible even when hoses or other equipment are temporarily stowed nearby. Check the sign periodically during routine fire equipment rounds to confirm it remains legible and the connection beneath it is free of obstruction.

• Standard IMO/ISO 17631 fire control symbol – red foam nozzle pictogram with “F” designator
• Photoluminescent base for visibility during blackout or power failure
• 150x150mm rigid or self-adhesive format to suit steel, aluminium or GRP surfaces
• UV-stable, corrosion-resistant construction for machinery space and open deck use
• Matches fire control plan symbols exactly for fast, confident equipment identification
