A team were attempting to remove the choke line hose (CLH) from the BOP with the help of a forklift truck. When they found the CLH was stuck, the Night Tool Pusher instructed the floor man to collect a pry bar. While the team were waiting for the pry bar, the derrick man tried to release the CLH, using a sledge hammer. Whilst hitting the flange with the hammer, the CLH became free dropping on his left foot.
