Slipped jack lets fall chassis, seriously injuring mechanic.
When a mechanic tried to creep under the chassis that was raised and rested on supporting blocks, he found the height was a bit too low to do so. He further raised the chassis with a jack and went under it for inspection. Then the jack slipped up all of sudden, letting fall the machine. He was crushed under the fallen machine and seriously injured.



Corrective Action
1. Do not use a jack for supporting equipment, because it may possibly collapse due to a failure. Be sure to use appropriate supporting devices after jacking.
2. Use chocks to secure a machine firmly, while servicing it.
3. Keep inexperienced workers under the control of a work conductor during work.
