The Italian Grand Prix has been declared a heat-hazard race as high temperatures continue in the country following the summer heatwave.
A heat hazard is an official designation for an event where it is forecasted that temperatures will be more than 31C at some point during the race on Sunday.
The ambient temperatures around Monza, north-east of Milan, are expected to be in the mid-30C region all weekend.
They peaked at 36C on Wednesday afternoon near Milan’s Linate airport.
The ruling means drivers can use a system that flows cooled liquid, such as glycol, through a system of pipes in a fireproof top worn under their overalls.
The cooling kit is not mandatory, but any driver who chooses not to use it has to carry 5kg of ballast in their car to ensure they do not have a competitive advantage.
