On October 21, 2025, Schad personnel were performing demolition work on Kiln #4 at Carmeuse Lime. While moving a debris buggy into the kiln, the buggy became lodged on the ramp at the kiln entrance. A Schad employee attempted to free the buggy manually. When the buggy became dislodged, it shifted unexpectedly and struck the employee's right knee, resulting in a contusion.
