Water Extinguisher Identification Sign - Safety Signs by Caledonia Signs

A Water Extinguisher Identification sign is used to clearly indicate the presence and appropriate use of a water fire extinguisher, which is designed specifically for Class A fires—those involving solid combustible materials like wood, paper, textiles, and cardboard. The sign helps ensure that individuals can quickly identify the extinguisher and use it correctly in an emergency, reducing the risk of delays or misuse.

Water extinguishers operate by cooling the burning material below its ignition point, effectively stopping the combustion process. However, they are not suitable for electrical fires or flammable liquids, as using them in such situations can be extremely dangerous. The identification sign typically includes symbols or warnings that make these limitations clear, helping to prevent accidental or hazardous use.

These signs should be placed directly above or next to the extinguisher, in highly visible locations. Ideal settings include offices, schools, retail spaces, corridors, and other environments where solid combustibles are the main fire risk. In such areas, a water extinguisher is often the most effective and safest option, and the sign helps ensure it’s readily identifiable.

Installing a Water Extinguisher Identification sign also supports overall fire safety awareness. It helps staff and building occupants become familiar with the types of extinguishers available and reinforces training on how to respond to different fire types. Clear signage contributes to a more organised and confident fire response in case of an emergency.
