Formula 1 Race Director Michael Masi has confirmed that the FIA will analyse the consequences of Carlos Sainz's accident during the third free practice session at last weekend's Italian Grand Prix.
Sainz spun into the wall at Monza's Ascari Chicane, hitting it head-on which resulted in him being thrown forwards. There were suggestions that Sainz's HANS device had come loose, but the Ferrari driver has denied that this was the case.
"I think the belts are made to stretch," Masi told RacingNews365.com and other select members of the press. "You've got a human body in there, so there's got to be some give.
"You can't just keep everyone completely tied in, because there has to be a bit of give in things. We will look at the belt stretch, as we do with any major incident, or significant incident like that, and see what we can learn from it.
"Can it be improved? Let's have a look, let's try and learn from it."
Following Lewis Hamilton and Max Verstappen's collision in the race, where the seven-time World Champion was saved by the Halo, according to his Mercedes team, Masi says he has been "encouraged" by all of the safety features on the current F1 cars.
"I'm always encouraged by all of the safety features and the ever improvement with safety that we have," said Masi. "You look at Carlos's incident in FP2. Although it didn't look like much, it was quite a severe impact.
"Be it the Halo, be it equipment, be it car design, everything... there's always that constant evolution of improving safety as a whole."
