Following recent incidents, the Resources Regulator has identified a lack of preparedness and appropriate responses to tyre fires on heavy earth moving machinery at some mining operations.
When heavy earth moving machinery tyres are exposed to heat and fire conditions, additional risks are introduced that need to be considered and controlled appropriately. (Other pressure vessels located on mobile equipment should also be considered in this regard when preparing for and responding to equipment fires as well). When heated, heavy earth moving machinery tyres are susceptible to unplanned explosions. Debris from these explosions can be projected several hundred metres causing severe injury or death. Tyres can become unstable without warning and can remain an explosion risk for up to 24 hours.
