The major cause of fire in an F1 car is fuel spillage in case of an accident.
Fuel tanks are moved to the rear of the car to give the driver time to move out in case of a fire outbreak. Moreover, fuel tanks used in F1 cars are made from Kevlar and polyurethane. These tanks are structurally sound and robust. Being rubbery and elastic, they are likely to deform but very unlikely to puncture. This fuel tank construction has greatly reduced the incidence of fire outbreaks in Formula 1.
In case of fire, F1 cars do have a fire suppression system. This system is mounted in the survival cell. The fire suppressant in the system will prevent fire spread within the vehicle. The system can be conveniently operated by the driver or remotely by the team crew from the pits. This system significantly reduces the risks to a Formula 1 driver in case a fire breaks out.
In addition, marshals are equipped with fireproof overalls and extinguishers at all track access points.
