Alert 06 – 13 Dropped Object From Derrick
WHAT HAPPENED:
The incident occurred when a stand of drill pipe missed the elevators, fell across the derrick towards the driller’s side and struck the derrick structure. This impact dislodged a 2 foot x ¾ inch steel bar weighing approximately 3 pounds from the stabbing board ladder platform causing it to fall approximately 30 feet to the dog house below. The steel bar struck and passed through the upper dog house window, narrowly missing the driller. The window was constructed of shatter proof material but was not able to withstand the impact of the bar.
