CO2 Fire Extinguisher Sign – FS0070

CO2 Fire Extinguisher Sign – FS0070

This CO2 fire extinguisher sign shows the standard extinguisher pictogram above a black “CO2” label and a use-on chart, confirming that the extinguisher below it is charged with carbon dioxide gas. The chart on this CO2 fire extinguisher sign lists flammable liquids (Class B) and live electrical equipment as approved uses, while clearly marking that it must not be used on wood, paper, or textiles, and that the horn must never be held while operating the extinguisher.

Where this CO2 fire extinguisher sign is used

Because CO2 leaves no residue and does not conduct electricity, it is the preferred agent for switchboards, server rooms, and other spaces with sensitive electrical equipment where a powder or foam residue would cause further damage. The warning against holding the horn on this CO2 fire extinguisher sign exists because the discharge horn becomes extremely cold during use and can cause frostbite or cold burns to bare skin.

This sign is fixed directly to or beside the extinguisher it identifies, typically in engine control rooms, electrical switchrooms, and computer or communications spaces where flammable liquids or live electrical equipment are the primary fire risk. CO2 extinguishers are not suitable for open or well-ventilated areas, since the gas can disperse before smothering the fire.

On vessels carrying multiple extinguisher agent types across different spaces, this CO2 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, including the horn-handling warning specific to CO2 extinguishers, since selecting the wrong extinguisher or operating one incorrectly under pressure is a genuine and avoidable risk. This sign is commonly found alongside other extinguisher identification signage such as the powder fire extinguisher sign and the BC powder 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.
