Earlier this month, Tennessee Tech University was informed of a complaint regarding asbestos concerns with contractor drilling in Henderson Hall. In response to the complaint, which was filed with the Tennessee Department of Labor and Workforce Development, Division of Occupational Safety and Health, TTU’s office of safety and environmental services ran several tests and found no detectable levels of asbestos in the building.

During the renovations to Henderson Hall, several holes had to be drilled through the second floor and into the first floor ceiling. There were concerns that the dust that came from the holes contained asbestos. Previous test results on similar projects had shown no detectable levels of asbestos, but as a result of the complaint, tests specific to Henderson Hall were done.

There is asbestos in Henderson, which was built in the 1930s, but it is in materials like insulation and floor tiles, which are maintained in such a way as to prevent the release of asbestos fibers. TTU’s campus safety and environmental services office has records of where asbestos containing materials are located. 

The tests looked at the floor tiles where the drilling took place, as well as dust from plastic sheeting in Associate Dean of Arts and Sciences Kurt Eisen’s office and air samples throughout the building. All of the test results came back with no detectable levels of asbestos, according to methods developed by the U.S. Environmental Protection Agency.
