Fire Extinguisher colour code changes

You may be noticing a new colour on your workplace fire extinguishers and not sure why this is?

Well there has been a new standard come into effect being BS5306‐10:2019 “COLOUR CODING TO INDICATE THE EXTINGUISHING MEDIUM CONTAINED IN PORTABLE FIRE EXTINGUISHERS”

This new standard supersedes BS 7863:2009, which is withdrawn.

The major change is the colour‐code for class D Powder extinguishers (for metal fires) is changing from Blue to Signal Violet.

This change reflects the characteristics class D powders which are often very different to other powders and a clearer differentiation was felt to be necessary for the safety of the operator.

As a result, newly manufactured class D powder extinguishers will exhibit the new colour.

The Blue colour code for BC and ABC Powder remains unchanged and the colours used for all other extinguishers are also unchanged.
