Williams has demanded the FIA take action ahead of qualifying for the Japanese Grand Prix to ensure no further track fires occur after two more incidents during third practice.
FP3 featured two red flags as a result of track fires, the first after just six minutes at Turn 12, whilst the other was at 130R, bringing an early conclusion to the session.
It follows on from the two track fires which resulted in delays to second practice on Friday afternoon, frustrating the teams.
The fires in third practice were particularly costly, with most drivers, including Alex Albon and Carlos Sainz, unable to complete a full qualifying simulation.
"I think it's hampered all of us really," Williams team boss James Vowles told Sky Sports F1. "It's just when you get into the flow, you need a couple of laps on the softs to get it right.
"And we just didn't get that nor did anyone else for that matter."
Measures were taken by the FIA after the fires on Friday afternoon to prevent a repeat of Saturday, with the grass watered and cut in places.
Those measures failed, resulting in fears of further fires during qualifying at the Suzuka Circuit. With this in mind, Vowles suspects that the early stages of each qualifying section could be frantic.
"So definitely, we spoke to the FIA at the end of that one [FP3]," added Vowles. "No one wants these, and it's the same for everyone. That's the best way I can put it.
"So it's down to us to make sure that we don't get caught out by it. You just could probably run on the earlier side [in qualifying]. That's the only protection you've got."
The FIA has confirmed that it will take further measures ahead of qualifying to prevent further fires, something Williams has demanded happens.
"They've tried wetting the turf, but I think they have to look at other measures before qualifying," insisted Vowles.
