Not the most technical explanation of how our on-board fire suppression systems work in Formula 1, but the concept is there.
We hope our technical explanation gives you a bit more insight in to the fire suppression technology we use in Formula 1 -
1.) The main part of the system is the carbon fibre fire bottle, this contains 1.7kg of a gas type extinguishing medium that is non-corrosive, non-conductive and leaves zero residue.
2.) The extinguishing medium is contained inside the carbon fibre fire bottle in a rubber bag, upon electrical activation the fire bottle is pressurised via a Co2 cartridge and the pressure is transferred inside fire bottle and applied to the outside of the rubber bag, squeezing the bag and discharging the gas out of the outlet. This results in a constant pressure discharge in any orientation, even if the vehicle was rolling.
3.) The gas type extinguishing medium is distributed throughout the vehicle to the cockpit and engine compartments via pipework that is routed to each location.
4.) Finally the gas will reach a nozzle at each defined location, the nozzles are designed to atomise and distribute the gas at a required angle and flow rate to ensure the highest performance from the extinguishing medium.
5.) The components we use when manufacturing the Formula 1 systems go through constant design evaluation to ensure the components are made as lightweight and packaged as small possible to meet the stringent requirements of the Formula 1 world.
5.) As per FIA regulations, the on-board fire suppression system on any FIA regulated vehicle is designed to suppress a fire and give the driver/co-driver the time required to exit the vehicle in a safe manner. It is not designed for extinguishing a large vehicle fire.
