High Expansion Foam Supply Tank Sign

High Expansion Foam Supply Tank Sign – FS0126

This high expansion foam supply tank sign shows the IMO fire control symbol marking the tank that supplies foam concentrate to the vessel’s high expansion foam fire-fighting system. The symbol follows the standard IMO fire control symbol convention used on fire control plans and at the tank itself, so it is recognisable to crew regardless of language.

Where this high expansion foam supply tank sign is used

A high expansion foam supply tank holds the concentrate used to generate large volumes of foam for smothering fires in machinery spaces, cargo holds, and other spaces protected by a high expansion foam system. This high expansion foam supply tank sign marks exactly where the supply tank is located, so crew can confirm concentrate levels and connections quickly during an emergency.

This sign is fixed directly at or above the tank, typically in machinery spaces or dedicated foam rooms required by the vessel’s fire control plan, so the tank’s location is always obvious at a glance. If a fire calls for the high expansion foam system to be activated, crew need to confirm the supply tank is charged and ready without wasting time searching for it.

Every foam supply tank on board should be marked the same way, so crew build a consistent expectation of what to look for regardless of which part of the vessel they are in. A tank that blends into its surroundings or is left unmarked is far slower to find under the pressure of an actual fire than one identified by this sign.

This sign is checked during SOLAS fire safety surveys, where the surveyor confirms that the high expansion foam supply tank is clearly marked, that the sign is visible and unobstructed, and that its position matches the vessel’s fire control plan. Correct labelling of the supply tank is a standard item reviewed during these inspections, since a missing or obscured sign can slow down verification that the high expansion foam system is properly supplied.

New crew should be shown the location of the foam supply tank during safety familiarisation and fire drills, since knowing where the concentrate is stored without hesitation can materially affect how quickly the high expansion foam system is brought into service. Clear, consistent labelling like this sign removes that hesitation.

Consistent signage also matters during a routine walk-through inspection, since an unmarked or poorly identified supply tank can slow down an auditor trying to confirm the vessel’s fire control plan matches what is actually fitted on board. Fitting this high expansion foam supply tank sign at the tank keeps the fire control plan easy to verify against the equipment in place.

The foam supply tank and its concentrate level should be checked regularly as part of the vessel’s routine fire safety equipment checks, since a tank that is low on concentrate or cannot be found quickly defeats the purpose of having a high expansion foam system ready to use. Keeping this sign in good condition also makes it easier for the crew member responsible for testing to confirm the tank is accounted for.
