Bulldozer rollover events

What happened?

Bulldozer rollovers are a high-risk incident that can result in serious injury and death. They are also preventable.

There have been 10 rollover incidents on Queensland sites since December 2021, including the recent stockpile dozer entrapment incident (Safety Alert 420). Three other incidents occurred at surface mines in July, October and November this year. Six similar incidents occurred between December 2021 and June 2022. These incidents occurred at nine different surface mines.

How did it happen?

Incidents have included dozers working;

  1. on rehabilitation
  2. in bulk push
  3. during floor clean-up
  4. during bench preparation.

Rollovers occurred when the bulldozer was travelling forwards, in reverse and when parked. Some examples are shown in figures 1 to 4.

The New South Wales regulator has also highlighted similar incidents in that state and provided advice to operators.
