More about EN-3
EN 3 replaces the older BS 5423:1987, which was withdrawn in 1997. Until then the UK had a unique colour coding system to identify the various Fire Extinguishers. BS EN3 requires that at least 95% of the body of the extinguisher MUST be coloured red, allowing only 5% colour coded zones on the extinguisher.
