Oil leakage causes fork to drop, injuring worker.
Oil leakage was found on the lift side of a lift cylinder piping. A mechanic tried to fix the trouble by retightening the bolts on the piping, after lifting up the fork to the height of 1.5 meters. Now that the oil leakage could not be stemmed somehow, he once loosened the bolts, but he did so excessively.
As a result the hydraulic oil began to flow out, which in turn let fall the fork. A worker, who stood under the fork to shine a light on the work with a flashlight, was crushed by the falling fork and injured.



Corrective Action
1. Do not allow anyone to go under the fork. If it becomes definitely necessary to do so, take every precaution to ward off fall of the fork.
2. Evacuate the worker from under the fork to a safer place before loosening the piping connection.
