Hydrospray Fire Extinguisher Sign – FS0075

Hydrospray Fire Extinguisher Sign – FS0075

This hydrospray fire extinguisher sign shows the standard extinguisher pictogram above a red “Hydro-Spray” label and a use-on chart, confirming that the extinguisher below it is suitable for ordinary combustible fires only. The chart on this hydrospray fire extinguisher sign lists wood, paper, and textiles (Class A) as the approved use, while clearly marking that the extinguisher must not be used on live electrical equipment, flammable liquids, or flammable metal fires.

Where this hydrospray fire extinguisher sign is used

A hydrospray extinguisher delivers water with a wetting-agent additive through a fine spray nozzle, which improves how the water penetrates and cools ordinary combustible materials compared with a plain jet. Because it is still a water-based agent, it carries the same Class A only rating as the water fire extinguisher sign, and using it on electrical equipment, flammable liquids, or metal fires carries the same risks as using plain water on those fire classes.

This hydrospray fire extinguisher sign is fixed directly to or beside the extinguisher it identifies, typically in accommodation spaces, corridors, and other areas where ordinary combustible materials are the primary fire risk. Crew should always check the use-on chart before discharging an extinguisher on an unfamiliar fire, since a hydrospray extinguisher is not a substitute for a foam, powder, or CO2 extinguisher in spaces with electrical or flammable liquid hazards.

On vessels where hydrospray extinguishers sit alongside other portable extinguisher types, this hydrospray fire extinguisher sign lets crew confirm at a glance whether the extinguisher in front of them is the right tool for the fire, rather than assuming any water-based extinguisher is always suitable. This matters most in the first seconds of a fire, when using the wrong method wastes time and can make the situation worse.

Unlike the powder fire extinguisher sign, whose broad ABC and electrical rating makes it a general-purpose choice, this hydrospray fire extinguisher sign marks an extinguisher intended specifically for Class A fires, so crew should not assume it can be swapped in for a general-purpose extinguisher outside its rated use.

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

New crew joining a vessel should be shown the different extinguisher types and their use-on charts during familiarisation, since assuming any extinguisher will work on any fire is a genuine and avoidable risk. This sign is commonly found alongside other extinguisher identification signage such as the water fire extinguisher sign and the wet chemical extinguisher ID sign, so a vessel’s full range of firefighting equipment is clearly and consistently distinguished.

Because picking 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 properly serviced and in date.
