Key learnings from a High Potential incident.
HPI OSH Alert #478
Date of incident: 18 May 2016
Safety Flash issued: 20 May 2016
Whilst transporting a load of biosolids,
the driver lost control when
turning a corner causing the prime
mover and trailer to rollover.
The vehicle slid along the road for approximately 50
metres before coming to rest on the right hand side
shoulder. The load was contained and no product
was lost except for a minor diesel spill. The driver
exited through the left hand passenger’s door and
was treated for minor injuries.
Why did this happen?
The driver failed to identify the hazards and drive to the road conditions, approaching the bend in the road at
the wrong angle and at the wrong speed.
What will the business area involved in the incident do to stop this from happening
Work closely with the current transport contractor to:
- Develop and deliver a training package specific to the risks and operational requirements of transporting
- Develop and implement waypoint mapping along all transport routes from Water Corporation facilities to
drop off sites. Waypoint mapping is a software program that monitors driver performance to certain
criteria including elevations, speed limitations and cornering speed restrictions.
- Contractor to update their Work Instructions for each route with details of the preferred route and the
relevant waypoint details. Present the revised work instructions and waypoint plan to all operators
What will our organisation do to stop this from happening again?
Work collaboratively with the contractor involved to ensure driver performance and continuous improvement
programs are developed and implemented to prevent a recurrence.
Lessons learned and corrective actions will be shared and implemented across the Water Corporation,
including a review to understand the possible risks involved with product movement during transportation.
What key learnings can you discuss with your team to stop this from
1. Road transport services are a high risk activity
- Are our contractors aware of the risks associated with the service they provide?
- What measures does the business and /or contractors need to have in place to ensure all risks are
- Can we identify any driving risks that are not being adequately managed both internally and
2. Driver performance is a key factor to managing the risks associated with driving
- Are we aware of what programs our contractors have in place to ensure driver performance is
- What measures do we have in place to ensure contractors are aware and accountable for their driving
- Do we need to improve our own driver performance and awareness?
