Austrian Grand Prix Designated Heat-Hazard Race
Temperatures for Sunday's 71-lap Austrian Grand Prix, scheduled to start at 14:00 BST, are expected to reach 33°C. Due to this, Formula 1's governing body, the FIA, has declared the event a heat-hazard race.
This designation applies to any event where temperatures are forecasted to exceed 31°C while cars are on track. As a result, drivers are permitted to use a mandated cooling kit that circulates cooled liquid, such as glycol, through a system of pipes embedded in a fireproof top worn beneath their racing overalls.
The use of the cooling kit is optional; however, any driver opting not to use it must carry an additional 5kg of ballast in their car to prevent gaining a competitive advantage.
Context and Regulations
Austria is the first race this year to be declared a heat hazard, amid a heatwave affecting Europe and causing record temperatures in several countries, including the UK. The rule was initially introduced last year during the Singapore and United States Grands Prix, which were also designated as heat-hazard races.
Some drivers choose not to use the cooling kit due to discomfort and concerns over the coolant potentially running out before the race concludes. In such cases, the liquid heats to car temperature, which is significantly higher than ambient temperature, reducing the kit's effectiveness.
Temperatures inside the cockpit of a Formula 1 car can exceed 40°C. Drivers wear multiple layers of fireproof clothing, including a balaclava and helmet, making overheating a significant concern during races.
