On October, 16 at around 23:51 Hrs after completing 7” liner job, 2 singles and 7 stands of 5” drill pipe were laid down on to the catwalk pipe racks. While forklift was trying to remove the two 5” singles of drill pipe they fell from the tilted-out riggers of the catwalk pipe rack. The NTP came to stop the forklift and assess the next operation During this intervention the loader reversed unit away from piperacks. One Drill pipe rolled across second dill pipe hitting the IP on his left leg. Why it happened/Finding : Poor planning on removing Singles of Drill Pipe Pipe racks were in laydown mode contributed to make the task difficult. Could have stopped the job and elevated the racks to horizontal and removed the two singles SWA was partially enacted - Line of fire was not identified and poorly recognized No JSA /TBT were not held prior removing the two singles.
