Abstract
A gas/oil well drilling helper was fatally injured on June 5, 1984 when struck by a suspended conductor pipe. A crew was drilling a gas/oil extraction well; the drill bit had been removed from the hole, and a 40 foot conductor pipe had been lowered into the hole. The conductor pipe was removed from a well after it was determined that the hole was not the proper depth; the pipe slipped from its chain sling and fell, hitting one of the workers in the upper torso. Approximately 45 minutes elapsed before emergency medical assistance arrived on the scene, and the victim died before its arrival. It was concluded that the major contributing factor for this incident was that the chain sling was not wrapped tightly enough around the pipe. Other contributing factors were found to be the miscalculation of the depth of the hole necessitating removal of the pipe, the nonuse of tag lines for guiding suspended loads, the small size of the work deck, and the lack of critical situation response training for workers. It was recommended that the company establish a formal written safety and health program to address the hazards of the work.
