Foam Fire Extinguisher Sign – FS0066

Foam Fire Extinguisher Sign – FS0066

This foam fire extinguisher sign shows the standard extinguisher pictogram above a red “Foam Spray” label and a use-on chart, confirming that the extinguisher below it is charged with foam. The chart on this foam fire extinguisher sign lists the two fire classes the agent is rated for, wood, paper, and textiles (Class A) and flammable liquids (Class B), while clearly marking that foam must not be used on live electrical equipment or flammable metal fires.

Where this foam fire extinguisher sign is used

Because foam conducts electricity and reacts violently with burning metals, using it on the wrong fire class marked “do not use” on this foam fire extinguisher sign can turn a manageable fire into a much more dangerous one. Crew should always check the use-on chart before selecting an extinguisher, particularly in mixed-risk spaces where more than one fire class may be present.

This sign is fixed directly to or beside the extinguisher it identifies, typically in engine rooms, paint lockers, fuel storage areas, and other spaces where flammable liquids are handled alongside ordinary combustibles. Foam’s dual Class A and B rating makes it a common choice for spaces where both fire risks are present together.

On vessels carrying multiple extinguisher agent types across different spaces, this foam fire extinguisher sign lets crew confirm at a glance that they have picked up the correct extinguisher for the fire in front of them, rather than relying on memory or the extinguisher’s colour alone. This matters most in the first seconds of a fire, when using the wrong agent wastes time and can make the situation worse.

This sign is checked during SOLAS fire safety surveys, where the surveyor confirms that extinguishers are correctly identified and that their agent type matches what is recorded on the vessel’s fire control plan and equipment register. Correct identification signage is a standard item reviewed during these inspections, since crew safety in an emergency depends on picking up the right extinguisher without hesitation.

New crew joining a vessel should be shown the difference between extinguisher agent types during familiarisation, since selecting the wrong extinguisher under pressure is a genuine and avoidable risk. This sign is commonly found alongside other extinguisher identification signage such as the water fire extinguisher sign, the BC powder fire extinguisher identification sign, and the BCF fire extinguisher identification sign, so a vessel’s full range of extinguisher types is clearly and consistently distinguished.

Extinguishers and their identification signage are reviewed during routine equipment audits, and this sign should be checked at the same time to confirm it remains legible and correctly matched to the extinguisher it is fixed to. An extinguisher swapped during a refill or service and left with the wrong identification sign is a genuine hazard, since crew trust this sign to tell them what is inside.

Because picking up the wrong extinguisher can make a fire worse rather than better, keeping this sign accurate and legible is as important as keeping the extinguisher itself charged and in date.
