Abstract: At approximately 3:30 p.m. on March 18, 1998, Employee #1 was using a D8 CAT crawler tractor to push brush off a logging landing when the tractor fell through the brush at a 60 degree angle. The crawler tipped over on its left side and Employee #1 was either thrown off or jumped to the downhill side. The vehicle descended approximately 75 ft before it came to rest with the left push arm of the blade crushing Employee #1 under a pile of brush. He was found, face down, in the fetal position, topped by a pile of brush being compressed by the weight of the tractor. Employee #1 died of mechanical asphyxia.
