What happened?
A diver in the diving bell was hit and slightly injured by a water bottle containing a gallon of water (4.5kg). Diver #1 left the bell and was handing over to the next bellman. In the bell the remaining divers were organizing their gear before departing the bell. They were moving a partially frozen one gallon water bottles when a handle on a water bottle broke and the bottle fell into the transfer lock striking the diver #1 on left side of his head and then onto his shoulder.
The diver received medical attention; he had an abrasion on his head and a red mark on his shoulder. He was able to continue the Sat run reporting only minor soreness over two days, eventually back to normal.
What went wrong?
The handle of the frozen water bottle broke and fell on the diver standing at the bottom of the transfer lock.
What was the cause?
The bell temperature was elevated due to shallow water diving and the bell being well insulated. Divers were bringing in frozen bottles of water to help lower the internal temperature.
