AI-generated summary

David Bruce Scale, a 52-year-old experienced road broom operator, died from blunt force trauma when he entered a machinery crush zone while investigating a broom stow mechanism malfunction. The vehicle was running with the engine and hydraulic systems active. Key clinical lessons: (1) Mr Scale had documented a broom malfunction on 12 November 2007 ('broom no side shift or up and down') with no apparent follow-up; (2) inadequate hazard-specific training—his son could not recall receiving written or verbal operating instructions; (3) administrative controls (warnings, signage, general SOWIs) proved ineffective, especially for a worker operating alone in a remote area; (4) absence of risk assessment specific to the installed broom mechanism, despite the equipment being installed in 2006; (5) no emergency stop mechanism at point of exposure. The coroner found the death was foreseeable and preventable, highlighting the inadequacy of relying solely on worker compliance with safety instructions when machinery failures occur.

Contributing factors

  • failure to adequately assess risks specific to installed broom mechanism
  • inadequate training on procedure to follow if broom stow mechanism failed
  • working alone in remote location
  • broom malfunction on 12 November 2007 with no documented follow-up
  • reliance on administrative controls rather than engineering controls
  • absence of emergency stop mechanism at rear of vehicle
  • broom designed to operate with ignition on, limiting detection of faults with engine off
  • ambiguous or ineffective safety documentation and instructions

Coroner's recommendations

  1. In the event that Matthews Brothers Engineering Pty Ltd installs a broom mechanism to another vehicle in the future, due consideration should be given to the circumstances of Mr Scale's incident, and the identified risks should be addressed so far as is reasonably practicable to avoid a similar incident from occurring.
