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 extinguisher is two fold. Primarily it is to suppress a fire enough to allow safe exit from the car be that with the help of marshalls or by the drivers own power. The second purpose of a fire suppression system is to potentially save the car itself. If the right suppressant is used correctly the fire should be contained and ideally halted thus avoiding the car burning out completely.
