Whitman County, WA
Classification FALLING/SLIDING/ROLLING MATERIALS
Type Struck by falling object
Investigator narrative
Maintenance was being performed on 10 wheel truck. It appears that the chain slipped causing the truck to fall striking the victim. The victim died from possible internal injuries. Still awaiting Coroner's and MSHA's finding to complete the investigation.
Final MSHA investigation
Root causes
  1. Management's policies, procedures, and controls were inadequate and failed to ensure that persons could safely perform maintenance in the shop. The truck was not blocked or mechanically secured to prevent it from falling or rolling accidentally.

    Corrective action: Management implemented policies, procedures, and controls to ensure that when mobile equipment is raised, it is properly blocked while persons perform maintenance in the shop. All persons were trained regarding the new procedures and will be monitored to ensure that these safe procedures are being followed.

Findings from MSHA's final investigation report, which supersedes the preliminary narrative above.
