Worker crushed when truck rolled during mechanical troubleshooting

Date of incident: October 2015
Notice of incident number: 2015157620104
Employer: Logging company

Incident summary

A worker was troubleshooting a mechanical issue while underneath a service truck in the driveway of his residence. He disconnected one end of the driveshaft, causing the truck to roll. The truck dragged and pinned the worker, resulting in fatal crushing injuries.

Investigation conclusions


  • Unsecured truck rolled during mechanical troubleshooting: The worker had backed and parked the service truck in the sloping driveway of his residence. He disconnected the driveshaft but had not chocked, blocked, or effectively secured the truck. Further to this, the emergency brake was not fully depressed. All of these measures would have limited movement of the truck. As a result, the truck rolled from its parked position, dragging the worker and causing fatal injuries.

Underlying factors

  • Mechanical work conducted on a slope: The service truck was parked on a steep grade, of approximately 6% slope, in the worker’s driveway. This was not a suitable or safe area to conduct mechanical work.
  • Employer not informed of vibration or the need for repair: The worker did not inform his employer that the truck had developed a vibration or that he intended to remove the driveshaft to troubleshoot the problem. The firm requires workers to report maintenance issues and to have them addressed by a thirdparty provider.
