Lewis Hamilton has branded the yellow kerbs at the Red Bull Ring "dangerous" following a number of suspension failures ahead of this weekend's Austrian Grand Prix.
Daniil Kvyat's Toro Rosso and the Force India of Sergio Perez sustained suspension damage during qualifying after driving over the yellow kerbs lining the track limits.
World championship leader Nico Rosberg crashed out following a similar issue during FP3, with a subsequent gearbox change seeing him incur a five-place grid penalty after qualifying second.
His Mercedes team-mate Hamilton took pole in Austria, however, and while the reigning champion did not encounter any problems with the yellow kerbs, he admitted concern over the impact they were having.
"I can't speak for the other drivers but from me looking at it, those yellow kerbs are quite dangerous," said Hamilton.
"We've seen a couple of incidents already. I don't know how many more it's going to take before a car ends up in the wall and perhaps someone gets hurt.
"I'm sure [race director] Charlie [Whiting] and the FIA are looking at it but it's definitely an area we can improve.
"I think the idea's good because they don't want us running wide and using the outside of the circuit but perhaps another solution is going to be needed."
Hamilton was pleased to have come through difficult wet conditions to ensure he starts Sunday's race from the front of the grid.
"It was a really fun session. It's incredible how fast it dries up here, it's like driving through fog," he added.
"It was very, very slippery, but it was drying up corner by corner. At the end it was just about getting that last lap. I'm very happy."
