I’m repainting my heating register vents and noticed something on the ductwork I didn’t see before. Pics attached. Judging from a google search, it looks like the section of ductwork that connects to the baseboard is wrapped in asbestos.

I can’t find it on any other parts of my ductwork in the basement. Just on the pieces that connect to the baseboard register vents.

Should I be concerned? No plans to do any remodeling anytime soon. Is it worrisome that it’s so accessible to get at? And why would it only be used on this parts of the ducting?

I would say that looks like asbestos that I have done remediation on the white fibrous and board like material usually are I can’t tell the maroon color it could have been painted to encapsulate it.

The only way to know for sure is to test but this looks like it.

    Thanks. The photo with the maroon is a bit hard to understand. The maroon is actually the boards for the first floor. There’s a small bit of the white wrapper that can be seen in that photo. Wondering if there’s a reason only a small section of the vent was wrapped in it. It looks like just the piece that went to the baseboard vent has the white wrap on it. – Skc45x Oct 7 '20 at 21:45
  • Ok I see it now yes they used to insulate metal to wood with asbestos sheet material round pipes were dense but very fibrous if not painted usually from a white to a grayish color, people started paint it to encapsulate it of if in the open to keep it from looking so dirty, if you have a gas water heater or boiler it may still be wrapped up in the attic but people started removing it in the late 60’s and 70’s that I know of just using dust masks , today respirators. Tyvek suits rubber gloves and boots and wet it down prior to moving it if it is legal in your area some states it is not. – Ed Beal Oct 7 '20 at 23:19
  • Looks like more down votes with no reason 2 on this question. Possibly because it was still open ? – Ed Beal Mar 7 at 17:03
