At 1:00 p.m. on October 25, 2016, an employee was moving towards a side boom's hook to attach a choker sling. The employee tripped over the skids and dislodged the skid that was chocking the pipe. The employee was killed by a natural gas pipe of 12-inch diameter steel pipe weighing 2,000 lbs.
What Can We Learn?
Use of a Questioning Attitude would have enabled the worker to gauge if the path selected to attach the choker sling was optimal for his safety.
By using a Self-Check (Stop, Think, Act, Review), the worker would have considered the dangers of walking over obstacles while attaching the choker sling.
Overconfidence caused the worker to underestimate the risks in walking over the skids.
The Physical Environment was likely not safe for the employee to complete his work.
