[pdf] Many accidents on the drill floorwhile pipe tripping involve using tongs. Injuries result from being caught between tongs and being struck by swinging tongs. All tongs should be securely attached and anchored. When pulling the pipe, the hole shall be kept full from the trip tank. The hole shall be checked regularly to ensure that it is taking the correct amount of fluid. The volume required to fill the hole every 3-5 stands shall be recorded in the Trip Sheet until the bit is out of the hole.
