Formula One’s managing director believes tracks could be redesigned following an investigation into the accident that left the Haas driver fortunate to escape with his life, with only minor burns to his hands and legs and suspected broken ribs suffered.
The disturbing scene saw a fire break out at the Armco barrier on the exit of Turn Three, which forced the race to be stopped as medical services rushed to the scene.
Grosjean was soon pictured out of the car and speaking to medics while the flames were put out, to the relief of the millions watching around the world, and Brawn insists there could be major changes following an investigation.
“The other disturbing thing about the accident was that it penetrated the crash barrier,” Brawn told the Today show on BBC Radio Four. “That is another aspect we have to look at.
"The halo for sure prevented other body and head injuries that in the past would have occurred if an accident of this sort would have happened.
“[Redesigning tracks to have more run-offs] can be looked at, I don’t know if that’s feasible. In normal cornering we try to create a run-off area. But that was pretty much straight. Every aspect will be looked at in this investigation.”
Brawn also explained how the fire occurred, with damage to the chassis of Grosjean’s car.
“I think the shock for all of us was seeing a fire, we’ve not seen that problem for many years. For there to be a fire, it’s unusual,” Grosjean added. “Pretty much yes [we thought we’d eradicated that problem], the fuel cells in which contain the fuel are military standard.
"They’re sort of bullet-proof. It was very unusual to see a fire. When the severity of the accident became clear, we started to understand why that may have happened.
“The chassis ruptured and ripped some of the connections to the fuel cell away, so that’s where the fuel escaped.”
The medical car, which starts at the back of the grid in the event of such accidents taking place, was immediately on the scene to allow F1 chief medical officer Dr Ian Roberts to rush to Grosjean’s aid as medical driver Alan van der Merwe helped the effort to put flames out on his overalls.
“(It was a) Big surprise for us as well,” Van der Merwe, who was one of the first on the scene, told Sky Sports. “In 12 years I’ve not seen that much fire at an impact like that. We took a little while to process what was going on, I’m sure that was only a second or so but it felt like ages. And then Romain actually started to get out of the car himself which was pretty amazing after an accident like that.
“Not yet, we had relief when we got back here and saw he was ok.
“It just goes to show, all the systems that we’ve developed, everything worked and the halo, the barriers, the seat belts - everything worked how it should. Without even one of those things, it could have been a very different outcome.”
FIA race director Michael Masi immediately red flagged the race and brought the cars back to the pits, with extensive barrier repairs being required to the section where Grosjean crashed. An initial update confirmed that at least 45 minutes would be required to replace the complete ArmCo section that had been damaged before a full race restart could take place.
An hour and 10 minutes after the accident, the FIA confirmed that the race would restart at 3:35pm GMT.
