Austrian Grand Prix declared heat-hazard race by Formula 1's governing body the FIA

The Austrian Grand Prix has been declared a heat-hazard race by the FIA, Formula 1's governing body, ahead of Sunday's 71-lap race starting at 14:00 BST. The designation is triggered when temperatures are forecast to exceed 31C while cars are on track, with Sunday's race expected to reach 33C. The ruling allows drivers to use a mandated cooling kit that circulates cooled liquid, such as glycol, through a system of pipes.
