Formula 1’s governing body, the FIA, has declared a heat hazard ahead of the Italian Grand Prix at Monza after forecasting air temperatures in the mid-30s Celsius. The declaration follows new regulations introduced after the 2023 Qatar Grand Prix, where similar conditions prompted a review of driver safety protocols.
Under the rules, a heat hazard is triggered when the Heat Index exceeds 31°C during a race or sprint. Teams must install a Driver Cooling System, which includes a pump, plumbing, and a thermal store to circulate cold fluid through a fireproof vest via tubes. While every car must carry the system, drivers can opt out of wearing the vest, though they must compensate for any weight difference with 0.5kg of ballast.
Drivers like Oscar Piastri have tested the system, noting it offers modest cooling benefits but carries risks if it malfunctions. The first practice session on Friday will give all 22 drivers another chance to evaluate the setup before the race weekend begins.
