An employee was removing one of two roll plates from a motor stator. The roll plates were hot due to a baking process to cure their varnish coating. The employee attached an overhead bridge crane to the plate for support while the plate was unbolted from the motor stator. The crane was attached to the wrong roll plate, causing the unsupported plate that the employee was working on to fall onto his leg after the bolts were removed. The employee suffered a fracture to his lower right leg and a second-degree burn.
