During the move of the circulation tank from Thuleilat-47 to Rahab-133 on a graded road, the circulation tank came off the flatbed trailer because the driver had not secured the load. The sudden shifting of the load caused an impact onto the flatbed. This impact was transferred to the Prime Mover causing the steering wheel of the Prime Mover to turn suddenly. The spoke of the steering wheel hit the driver’s left hand. The driver was diagnosed with a fracture on the left hand ring finger.
