Sudden bucket movement shakes off mechanic inside.
A mechanic stepped in the bucket of a hydraulic excavator and was checking the pin securing the bucket. Not knowing that, another mechanic operated the bucket control lever. The bucket started moving and threw him off on the ground. He then tried to protect himself with his hands and sprained the wrist. .



Corrective Action
1. Before starting the machine, pay attention to the workers around as well as the neighborhood, and take safety precautions such as evacuating the workers and others.
2. Stop the engine while servicing the machine.
3. If it becomes definitely necessary to start the machine during inspection or maintenance work, appoint a work conductor and follow his/her instructions.
