The mines should confirm that those risk assessments take into consideration important information including using technical experts when assessing the risks associated with WBV and setting mine site standards; setting vehicle tyres, suspension, visibility and seat standards before use; and setting road standards and road maintenance practices at the mine, according to a New South Wales government safety alert.

The analysis identified 318 separately reported incidents of drivers or passengers who had received injuries ranging from minor sprains or strains through to spinal fractures. These injuries were a result of WBV transmitted to the driver or passenger of the vehicle in which they were travelling.

WBV may sometimes simply cause discomfort. However, longer exposures to moderate or intense WBV or large single impacts are often linked to long term issues such as early degeneration of the neck and lower spine, among other problems.

Back disorders are believed to arise from damage to the spine and surrounding structures brought about by an accumulation of strains placed on the back over time.

Key risk controls to prevent and mitigate injury from WBV caused by road transport systems include fit-for-purpose roads. Roads need to be of a suitable standard for both the intended use of the road and the type for vehicles used on that road.

“Reasons for road deterioration should be understood and managed, such as water drainage, tyres which are too hard, excessive vehicle speeds, and machinery movements,” the report states.

“Road conditions should be regularly monitored with timely repairs.”
