The day I moved into the college dorms he looked at me and said "Don't move the floor tiles, ceilings tiles or the touch the large ventilation pipe outside my door in the hallway." A lot of the buildings at my university were built with asbestos, so much so that the university had a 30 year contract with the lab he worked at to analyze samples.
And it isn't only historical buildings that have asbestos. A very well known mall that was built in the 2000s had incurred some severe hail damage and while the repairs were ongoing samples were taken and found to be hot. Someone had introduced asbestos contaminated materials into the original build and rather than extensive repairs the mall had to do extensive remediation first, before continuing repairs.
Apparently there is still a large stock of "hot" building material that are sitting in warehouses and every once in a while they make it into the supply chain.
