A dozer was being used to cut a drainage ditch in a roadway berm. The accident occurred when the left side of the dozer blade ruptured a 16-inch diameter high-pressure natural gas transmission line, leaving an 18-inch long gash in the pipe. The sudden release of pressurized gas blew out all of the windows in the dozer cab and peppered the operator with flying rocks and debris. There was no explosion or fire. The operator was able to exit the cab and run from the area. The operator was transported to the hospital, treated for minor abrasions, and returned to work later that day.
