Two Power Lines Down (KV5v2)

 

What Happened?

1st Incident: A supervisor told a general worker to move a pole truck out of the way. The worker complied, but failed to check the height of the poles on the truck. While driving, the extended pole made contact with an overhead ground wire causing it to break and fall to the ground.

2nd Incident: After a lengthy (2.5 hour) safety stand down, a loaded truck was leaving the location and was rounding a right hand curve on the site road. The truck driver pulled over on the shoulder to avoid another company truck parked on the side. Driving on the steep shoulder caused the load to lean and made contact with a power pole. This caused the pole to break and fall across the road. The incident occurred 75 yards past the first incident.
