The Colour Code for Fire Extinguishers

It is critical to have the right fire extinguisher for the right job in all situations but none more so than in motor racing. The aim of a racing car fire suppression system is to suppress the fire long enough to allow for the safe exit from the vehicle of the occupants either by themselves or with the help from trackside marshals. The FIA standard states that the fire suppression system is mainly designed to delay the development of the fire and consequently give the driver more time to exit the car. The system is not designed to put out the fire and prevent the car from burning.

Fire extinguishers in the United Kingdom are generally colour coded to identify the extinguishing medium that has been used, by use of a coloured patch:

  • A Cream patch on a red extinguisher denotes a FOAM fire extinguisher.
  • A Blue patch on a red extinguisher denotes a POWDER fire extinguisher.
  • A BLACK patch on a red extinguisher denotes a CO2 fire extinguisher.
  • A RED patch on a red extinguisher denotes a WATER fire extinguisher.
