An employee was operating an extruded polystyrene foam (XPS) block downcutting apparatus to cut 4x4x8 foot XPS blocks into smaller sections. The 240-volt electrical wire disconnected from one side of the downcutting apparatus. As the employee went to reconnect the wire, he was shocked, causing him to fall approximately 30 inches to the production area floor. The employee sustained an electric shock to the left hand/arm and a possible left shoulder injury from the fall.
