I see we have a resident asbestos expert. A few years ago I was responsible for removing some equipment that was mounted to the drop ceiling before they demolished a room to renovate. A few days after my part while they were mid demo the asbestos remediation signs showed up and big tubes were strung through the hallways. I didn’t work in that building so I’m not worried about what was disturbed by demo and spread around but have to wonder how much exposure I got being in the plenum space for about fifteen minutes.
