Mechanic sprains ankle, jumping off machine
A mechanic was trying to drain hydraulic oil as a prior step for replacing a hydraulic pump and found a necessary tool was not ready at hand. He jumped off the machine to fetch the tool, but unfortunately landed on a pebble and had his right ankle sprained. No appropriate ladder was available to him, as the pump replacement took place on a jobsite.



Corrective Action
1. Do not take such a hazardous action as jumping off a machine. For getting on and off a machine, make use of the climbing steps, ladder or handrail provided on the machine.
2. Park a service vehicle or prepare for tools at the side of a machine where climbing steps, ladder or handrail are provided.
