An employee was conducting grinding operations on a flange weighing 265 pounds. The flange was supported by two metal saw horses. After the employee finished grinding on the top side of the flange, the flange had to be flipped over to grind the bottom side. A crane was used to lift and flip the flange. As the flange was being flipped over, it started to fall off one of the saw horses. The employee attempted to grab the flange. The employee's middle finger on his left hand was caught in between the flange and the saw horse. The employee was hospitalized for a compound fracture of the left middle finger that required surgery.
