Fire Extinguisher Colour Coding or Colour Bands

Current fire extinguishers in the UK are subject to strict standards and that includes their colour coding or colour bands.

Fire extinguishers that meet the BS EN3 standard are manufactured with a red body and have a zone band of a second colour, covering up to 10% of the surface, that indicate the extinguisher’s contents. Each type of fire  extinguisher has a particular zone of colour making it easier for the user to identify the contents of the fire extinguisher.

Older fire extinguishers that pre-dated the current standard are still found. These extinguishers were in colours other than the now predominantly red colour required to conform to BS EN3 and may still be legal. However, if they need to be replaced because they are unserviceable or damaged, the new extinguisher needs to comply with the new requirements if it is to meet the BS EN3 standard.

Typical colour zones of current fire extinguishers in the UK and the key features of each are:
