Final MSHA investigation
On August 21, 2020, Dennis A. Dose, a 69 year-old tractor-trailer driver with ten years of professional over-the-road driving experience, sustained fatal head injuries while he was deploying the tarp system on his fifth-wheel side-dump trailer. After activating the automatic tarp deployment system, Dose was walking beside the trailer when the tarp system drive chain came off the sprockets. This caused the tarp roll tube to deploy uncontrolled and strike him in the head.
