Need someone with car knowledge..

[Engine]

So yesterday I was at my local race track helping out as fire and rescue. I had to go out to an incident where under someones engine bay their booster cables caught fire(drift car)and the driver said the mat was asbestos(cancer causing chemical) and it was burning.. the car was a 1995 skyline if that's any help. I didn't breath the shit in and I've since taken the proper precautions required but I want to ask, do some cars actually have asbestos in certain parts or at all?

I've googled it and can't find any info.
