A garage attendant was killed while removing tires from a vehicle. He had positioned a bottle jack under the axle frame at each end near the spring. He needed to raise the bottle jacks to align the bolts and reinstall the tires and he crawled under the car to raise the jack. The jack slipped out, allowing the weight of the truck to shift and come down on him.
Blocking and stand jacks are important tools used in garages or while repairing powered mobile equipment in the field. Blocking and stand jacks are used when working under a raised load to keep it from falling. Workers can be seriously injured or even killed if proper equipment isn’t used or if it isn’t used correctly.
