Know Your Fire Extinguishers Colour Code Signs
This fire extinguisher colour code sign gives staff and visitors a quick visual guide to water, dry powder, foam, CO₂ and wet chemical extinguishers. Display it near fire points or safety information areas to explain fire classes, permitted uses and key restrictions before an emergency.
Where this colour-code guide works best
Install the sign close to mixed extinguisher points, staff safety areas or places where people may need to compare extinguisher types. Keep it at a comfortable reading height, unobstructed and well lit so the colour blocks, fire classes and restrictions can be checked without searching.
Choosing a readable size
Choose the size around the normal approach distance, not just the available wall space. Use the 300 mm-wide version for close reading and the 500 mm-wide version where people first see the guide from farther away. These distances are practical selection guidance, not certified legibility ratings.
| Size option | Practical viewing range | Best suited to |
|---|---|---|
| H 250 x W 300 mm | Around 2–3 metres | Close-reading positions beside fire equipment |
| H 300 x W 500 mm | Around 3–5 metres | More open areas and longer approach lines |
What better placement should achieve
Placed where people naturally pause at fire equipment, the sign can reinforce training by helping users compare extinguisher types, recognise prohibited uses and understand that one extinguisher is not suitable for every fire class.

Installation Guidance
❌ Do not fit the sign behind extinguishers, doors or stored items where the lower guidance becomes hidden.
❌ Avoid positioning it so high that users can recognise the colours but cannot comfortably read the fire-class information.
❌ Do not select the smaller size simply because it fits the wall; first check it from the normal approach position.
❌ Do not use this information chart as a substitute for the correct dedicated fire equipment location sign.
❌ Do not rely on it as the only source of extinguisher instruction for people who have not received appropriate fire-safety training.
❌ Avoid treating the printed colour guide as confirmation that every extinguisher shown is actually provided at that particular fire point.
✅ Install it where users can view the complete chart while standing naturally beside or approaching the fire equipment.
✅ Match the fixing method to the selected material and mounting surface, using separate fixing materials where required for Rigid Plastic.
✅ Recheck visibility after installation and whenever nearby equipment, furniture or storage arrangements change.
Frequently asked questions
What is the Know Your Fire Extinguishers Colour Code Sign used for? It gives you a visual comparison of water, dry powder, foam, CO₂ and wet chemical extinguishers, including the fire classes and restrictions shown for each type.
Where is this fire extinguisher colour code chart most useful? Position it where several extinguisher types are grouped together or where staff regularly refer to fire-safety information. It should be easy to read without moving equipment or searching for it.
Which size should I choose? Choose H 250 x W 300 mm where people normally read the information close up. The H 300 x W 500 mm option gives the content more presence where the approach distance is longer. Check readability from the actual mounting position before fitting.
Is this sign photoluminescent? No. The supplied specification states that it is non-photoluminescent and non-reflective, so choose a different product if glow-in-the-dark performance is specifically required.
Does this replace a dedicated fire extinguisher location sign? No. This product is an information guide. EN ISO 7010 F001 identifies the standard fire extinguisher location symbol, so use the appropriate dedicated equipment identification where that function is required.
Does the colour-code guide replace fire-safety training? No. Use it to reinforce awareness and refresher training, not as a substitute for your fire-risk assessment, procedures or staff instruction.
Can I install it outdoors? The supplied specification lists indoor and outdoor display. Select the material and fixing method around the mounting surface and the exposure at the intended position.
