Bolt tightening
A worker is retightening a cylinder pin stopper bolt.



Various Points of Hazard
1. The worker let the bucket stand and work on the cylinder at a high position, taking an unsteady posture.
2. The worker does not use a regular scaffold or a stepladder. He may likely lose his balance and fall off on the ground, when the spanner slips off the stopper bolt.
