I was reading a 1970s Kenmore dryer manual and found out they originally shipped with a 6-foot asbestos heat shield cord | Appliance Repairers - Librear
People get really worked up about asbestos, but it's only dangerous if you're breaking it up and breathing the dust for years. A heat shield cord that's been sitting there for fifty years, still in one piece, isn't exactly a ticking time bomb. The risk from a single, intact part like that is pretty much zero in my book. Replacing it is fine, but treating it like a biohazard seems like overkill. It's not the same as tearing out old pipe insulation every day.
