EE was replacing a valve. EE was using a torch to remove flange bolts, once EE was down to the last bolt, water that was trapped in the line started to spray out from around the flange. Not wanting to get wet, EE took a step backwards and tripped over a curb. EE put EE's hands out to catch self and bent EE's right wrist backwards, this resulted in a fracture of EE's wrist.
