Asbestos in vintage dryers?

Just curious if any of the internal components on older drying ovens -- like insulation material, boards, gaskets -- ever contained asbestos. Anybody know if that was ever used?

Asbestos was widely used in many different products.... but is only hazardous in it's friable form (dust). Wiping dust up with a damp rag is the most practical way to dispose of questionable dust.
Most states require training and testing to be a qualified asbestos remediator.
The abated material goes to a special landfill.
