The China Petrochemical Corporation's Guangzhou Factory caught fire on Thursday afternoon after four oil pumps leaking oil were ignited.
The fire had been extinguished by 8:45pm, Xinhua News Agency reports.
To date, there are no reports of death or injury from the accident. And the reason of leakage is still under investigation.
Later, the factory held a press conference, after ensuring the wax oil's hypergolic ignition would not result in an explosion. But it admitted the air of its surrounding environment would be poisoned.
Lu Jianming, part of the factory's managerial staff, said at the conference he estimated the fire caused a loss of several tons of oil. But indirect loss, including pumps and cables, is bigger. As well as the set of oil pumps that was destroyed in fire, there are two other sets of refinery oil pumps that can continue to produce.
The managerial staff also added the accident would have little impact on the supply of refined oil in Guangzhou city which has an ample oil reserve, despite a possible decline in the factory's refined oil output.
