Abstract: At approximately 10:00 a.m. on July 7, 1999, Employee #1 was working for a grading contractor that had been hired to remove contaminated soil from a 40 ft by 200 ft runway site. A bulldozer operator was using a pan scraper to scoop up soil along the southeast area of the taxiway. He had finished a pass and was backing up, traveling south, with the blade raised to get set up for another pass. About three-quarters of the way back through the cut area, he noticed something white in front of the bulldozer. He stopped, lowered the blade, and dismounted, whereupon he discovered that he had run over and killed Employee #1.
