PHOENIX - A preliminary report indicates that the cause of a large oil-fueled fire in Phoenix Tuesday morning may have started while workers were transferring oil from one tanker to another, according to fire officials.
Fire officials said the pump being used to move oil from one tanker to another may have been leaking onto a mechanical part and then ignited.
Huge plumes of black smoke could be seen across the Valley around 7 a.m. Tuesday. The fire started in an industrial area near 24th Street and Jefferson.
Fire officials said the business is fully cooperating with authorities. Two workers, ages 23 and 45, suffered severe burns in the fire and were being treated at Maricopa County Hospital.
The company has hired an outside contractor to clean up the area. As of 2 p.m., fire officials said crews have about half of the mess cleaned up, but it could take a few more days to have everything cleaned up.
The investigating is on-going.
