While operating a vibrating compactor, a worker was killed when the compactor tipped over, crushing him between the roll-over-protective (ROPS) canopy and the ground. When he backed up the machine, the left rear wheel went up a short incline and the machine became unstable and tipped over. The worker was not wearing a seat belt. He fell, or jumped off the operating seat to the ground, where he was crushed by the ROPS canopy. A seat belt was available, but it was not used.

Safe work practices:

• Ensure that workers receive adequate direction and instruction in the safe performance of their duties.
• Use seat belts while operating mobile equipment.
• Review the operator's manual with new equipment operators before they operate equipment.
