EMPLOYEE KILLED WHEN STRUCK BY MOVING PIPE

Emplo yee #1 was instructed by the rig supervisor to relieve the pressure behind the u nit so the leak could be repaired. While Employee #1 was doing this, he inadvert ently released the pressure that activates the blowout prevention device. This c aused a surge of air to be released through the horizontal flow pipe, and the pi pe swung around and struck Employee #1. The horizontal flow pipe was not secured to prevent it from swinging around.
