Formula One's governing body declared a heat hazard for the Austrian Grand Prix at Spielberg's Red Bull Ring this weekend, the first time this season that the designation has been used.
Race Director Rui Marques said temperatures in excess of 31 degrees Celsius (88 degrees Fahrenheit) had been forecast.
Declaring a heat hazard requires teams to fit a driver cooling system, such as a liquid-cooled vest, though drivers are not obliged to use them and can take a ballast penalty instead.
The car's minimum weight is increased to accommodate the hardware.
