Asbestos in old furniture adhesive?
As I've posted before, the risks of asbestos exposure on a very infrequent basis in a residential setting are highly over-blown. The real risks were for construction workers (pipe insulators, HVAC insulators, etc. ), back 50-60 years ago who where exposed to asbestos dust on a daily basis. I know the lawyers will hate me for saying this, but frankly asbestosis only occurred in an industrial setting not one off residential exposure to tiny amounts of asbestos.   It's not a poison, just an irritant that can lead to lung damage over a long period of time.  It's serious, but a one time exposure, probably very little, isn't anything to worry about.
