Hello
I had asbestos tunnels connected to 100 mm metal pipes for natural ventilation. The company that installed the new ventilation system agreed that all materials would be new, so they ordered new pipes and dampers. But in the bedroom, they reused the old metal pipes that were previously connected to the asbestos tunnels as exhaust pipes, and now they use them for supply air. This change was made without my knowledge. According to WHO, all materials that have been connected to asbestos are considered contaminated. I realized they had used the old pipes when I noticed that nothing had been scrapped, even though the old pipes were missing. The contractor has now admitted that they reused the old pipes.
The contractor has since fixed the pipes and insulated them. Should I demand that they replace the pipes with new ones? What should I do?
Regards

What might remain in the metal pipes are likely residues from the asbestos pipes and possibly what has come loose during work on the pipes. So the options are:
* Leave it be.
* Clean with something that has been documented to bind asbestos particles.
* Replace all pipes again.
Then the question is how much asbestos is present in the rooms from all the years the asbestos pipes were installed. One approach that might work is, of course, either cleaning with something that has been documented to bind asbestos particles or replacing all surfaces, which might be as simple as painting the walls, ceiling, and replacing the flooring or sanding planks.
One way to resolve this is to actually measure the presence in ventilation ducts and in the ceilings, walls, and floors of the rooms. Assuming that furniture was changed during ownership transfer anyway.
In the end, it's a question of how far one is willing to go to defend their health.
(which company did this without consulting is obviously interesting as well)

These metal pipes were connected to exhaust ports in a room we don't use; in fact, these ports will be sealed since there's some asbestos we don't touch. New ports have been made for the new system, but unfortunately, the contractor may be trying to save money by using the old pipes. My opinion is that we should use new pipes and new exhaust or intake points.spikplanka said:
