What kind of accident is about to happen?
A worker in the bucket of an aerial lift is trying to do some wiring on an overhead crane of a factory building with an uneven floor.
Can you predict what's about to happen?

Look what happened!
When the worker tried to turn the bucket to do the wiring, the aerial lift wobbled because it was positioned in an unstable location on an uneven part of the floor. The worker's chest was crushed between the railing of the bucket and the overhead crane rail.


Tips for preventing similar accidents
1. Plan ahead of time where an aerial lift is going to be located, and be sure there are no uneven spots in that location.
2. Before performing work, be sure that aerial lifts are completely stable.
