A fireball engulfed half of a drill rig while in the process of drilling a shot hole. Subsequent investigation revealed the cause of the fire was the failure of the oil return hose to the separator/receiver in the air compressor. The failed hose was a 50.8 mm 100R1 type hose, as specified in AS 3791-1991 Hydraulic Hoses. This type of hose consisted of an inner tube of oil-resistant synthetic rubber, a single medium-carbon steel wire braid reinforcement, and an oil-and-weather resistant synthetic rubber cover. The wire braiding was found to be severely corroded in the area of the failure...
