Death toll from pipeline blast rises to 52, 11 missing

The death toll from Friday's oil pipeline blasts in east China's Shandong Province rose to 52 as of 1 p.m. Sunday after four bodies were found at the scene, rescuers said.

Reports and investigations showed that 11 others were missing in the deadly accident, the rescue headquarters said.

Among the dead, four have not yet been identified, according to the rescue headquarters for the blast accident, which occurred at Huangdao district in Qingdao City.

Six of the dead were professional firefighters with the Huangdao oil warehouse of Sinopec, China's largest oil refiner.

Rescue efforts continued Sunday despite rainy weather. The complicated situation and the remains of flammable gas at certain sections in the explosion area hindered the debris-clearing progress.

Crude oil began leaking from an underground pipeline operated by Sinopec at 3:00 a.m. Friday in Huangdao District of Qingdao, according to the municipal government. The valves of the Huangdao oil warehouse were shut about 15 minutes later.

The oil spill then flowed into the city's rainwater pipe network, which empties into Jiaozhou Bay. Two blasts occurred at around 10:30 a.m. Friday when workers were repairing the ruptured pipeline.

The damaged pipeline was put into use in July 1986. It is the second pipeline linking Dongying City in Shandong with Huangdao. The pipe measures 711 mm in diameter and runs 248.5 km, with an annual oil transfer capacity of 10 million tonnes.

Ten of the 136 hospitalized are in critical condition, according to provincial health authorities.

About 18,000 residents were evacuated following the explosions, which ripped through roads, overturned vehicles, and shattered the windows and bricks of nearby buildings.

Sinopec's board chairman, Fu Chengyu, apologized for the accident on Saturday. He vowed all-out efforts to handle the rescue, relief and aftermath and to cooperate with the investigation team of the State Council to find the cause of the accident.
