Alert 07 – 19 Improper Use of Retractable Life Line Results in an LTI
WHAT HAPPENED:
After latching a stand of drill collars into the elevators, the derrickman turned to prepare for another drill collar stand to be picked up. The cable from his working retractable life line snagged the inspection door of the traveling blocks. As the blocks were traveling down, the snagged cable pulled on the derrickman’s harness forcing him to squat on the monkey board. The derrickman’s left leg went between the fingers in the monkey board, and the pressure of the blocks going down broke his ankle.
