Bulldozer movement kills operator standing on track.

NIOSH 2006 May; :1-5
On August 20, 2005, a 33-year-old Hispanic equipment operator was killed when he slipped between the tracks and the body of the bulldozer he was operating. The operator gave a coworker a ride to retrieve an ATV located at the top of a hill where the operator was intending to work. The operator stopped the bulldozer on a fairly level area of the slope to let off his rider. He then noticed the coworker had left a jacket in the cab, so he lowered the tractor's blade to the ground, put the machine into idle, and stood on the track to reach out and give the jacket to the coworker. While in this position, the tractor suddenly moved backward, and the operator lost his balance and fell feet first between the track and the deck. The bulldozer continued to roll 8-10 ft backward, and the operator was pulled beneath the tractor and crushed. Coworkers freed the conscious victim, but he was confirmed dead when emergency medical responders arrived at the scene. The medical examiner reported a blood alcohol content of 0.08, the level of legal intoxication in Oregon for operating a motor vehicle. Recommendations: 1. Before exiting a bulldozer, the operator must secure hazardous energy by following all manufacturer recommended steps in parking, including setting the parking brake. 2. Operators should not use alcohol or other impairing drugs prior to or while operating equipment. 3. No passengers should be permitted to ride on mobile machinery, unless a properly equipped seat is provided.
