thank heavens for that... had to take one out to get to the wiper linkage and a load of dust came off it which I breathed in. Couldn't be entirely sure whether it was card or asbestos though.
Went through the same feeling when I happened to pull out some of the old hessian type sound proofing behind the dash. Dust everywhere! I was told if it catches fire... it's not asbestos, so if the part is scrap and it'll burn you are ok.
