Alert 12 – 31 High Potential – Dropped Pony Collar
While laying down an approximately 16 foot x 10 inch (4.8m x 25cm) pony collar, weighing approximately 3400 pounds (1.5mt), the 500 ton (454mt) center-latch elevators opened inadvertently. The pony collar fell 6 feet (2m) and came to rest on the pipe skate. In the process of falling, the lift cap struck the stump, but there was no visible damage to the remaining BHA. No personnel were in the area.
