What Is Heat Hazard In F1, The Caution FIA Issued For Italian GP?
"In accordance with Article B1.5.10 of the FIA F1 Regulations, having received a forecast from the Official Weather Service predicting that the Heat Index will be greater than 31.0 °C at some time during the Race at this Competition, a Heat Hazard is declared," FIA said in a statement on Thursday.
The ruling means drivers can use the cooling, whic has a "sole purpose" of providing additional cooling for drivers under a ‘heat hazard’ scenario. Several components are involved, including a pump, plumbing and thermal store, with cold fluid generated by the system delivered to the drivers through a special fireproof vest featuring various tubes. All of the core system components must be fitted to cars, though drivers are currently permitted to choose whether or not they wear the vest itself as work continues on fine-tuning the design.
