While replacing equipment at Sunny Hill Elementary School in Carpentersville, IL (outside of Chicago), workers identified asbestos in the glue that was used to mount whiteboards.

Officials say the asbestos at Sunny Hill Elementary in Carpentersville was “most likely” not airborne and students were not exposed to it.

“The good news is that the asbestos was not airborne at any time and can be completely and safely contained by putting up new drywall and repainting the four classrooms,” Superintendent Tom Leonard said in a letter to parents.

Thanks to the alert and well trained crew who identified the asbestos in time, to contain the dangerous substance before endangering the health of the students and staff at that school.
