Abstract: At 2:30 p.m. on November 21, 1991, Employee #1 and two coworkers were conducting exploratory drilling using an Ideco Back-in Ramble 800 drilling rig, serial #AL-980, with an Ideco 260 ton substructure and a mast about 96 ft high. Employee #1 and the coworkers were attempting to remove the drill bit from the bit sub to get to the 6 R float valve. After latching the tong onto the bit sub, Employee #1 was standing between the tong and the tong's 3/4 in. diameter horizontal steel cable and was caught and pinned between the tong and cable. Employee #1 sustained extensive chest and abdominal injuries and was pronounced dead at the hospital. The coworkers were not injured.
