Moving
parts with a crane |
Taking down from a
construction machine, a worker is now putting a control valve on a working
bench with a crane. |
|
|
Various Points of Hazard |
1.
|
Unless the
worker brings the working bench direct under the hoist, the bench may be
pulled down toward the worker due to the weight of the control
valve. |
2.
|
The worker's
left hand may likely be crushed under the descending control
valve. |
