Cars with an annual inspection involved in an incident, must be re-teched before being allowed back on the track, and have the annual inspection revalidated before use at subsequent events . On board fire extinguishers are mandatory and must be securely fastened inside the cockpit area. The extinguisher must be Halon 1301 or 1211, minimum 2 pound, with a charge indicator. A 2 or 3 point Halon or AFFF system is highly recommended.
Fuel cells are mandatory in all race groups except pre-war.
The cell must be fully enclosed in a metal container with a positive locking cap. The cell shall also incorporate foam inside a bladder. The cell shall be vented to the atmosphere, though a check valve, to provide leakage protection in the event of a rollover. The vent shall exit the vehicle outside the driver's compartment and outside the fuel compartment. Fuel cells installed in a factory original tank position must be verifiable upon inspection.
