A report has been released by the Wildland Fire Lessons Learned Center about a dozer rollover that occurred July 2, 2016 at the Trailhead Fire on the Eldorado National Forest in California. You can read the entire report, but here’s a brief summary.
After getting unstuck from being high centered on a large stump, a dozer operator found himself off the ridge where he was building an indirect fireline, and was on a steep slope. Again he got stuck and was not able to backup, this time due to the slope which in places exceeded an 80 percent incline. At various times he was advised by two Resource Advisors, the Structure Group Supervisor, and the owner of the dozer to stay put. In the meantime another dozer with a winch was en route to assist.
Ignoring the advice, the operator continued down the slope and got into a heated argument with the owner, who then left the area. Determined to get the dozer back up to the ridge top, the operator began building a road and creating pads where he could work to push over trees that were in his way, including a 30-DBH cedar which missed by 50 feet the two Resources Advisors who had to run to get out of the way.
The incident-within-an-incident finally came to an end, at least temporarily, when the dozer rolled over onto its side. The operator escaped with only a scratch, after which the dozer continued to roll over onto its top in the creek bottom.
The report did not include information about how the dozer was eventually extracted, or what repercussions, if any, befell the operator and the contractor.
