Old ductwork that turned out to be asbestos

Removing an old system, we found ductwork that looks like cardboard. It's asbestos, a Class 1 carcinogen found in many older homes. We brought in a licensed third-party asbestos removal company to take it out. If an ordinary crew tore it out, the fibers would settle through the attic, the walls and the new ducts, and the damage to the lungs is permanent.
