Safety hazards have been found at almost 70 percent of firms handling dangerous chemicals inspected in Beijing since two massive blasts killed 114 people last week, including a branch of Asia's largest refiner Sinopec Corp. state media reported late Thursday.
An inspection of 124 sites that stored dangerous chemicals in the Chinese capital found hazards at 85 firms, the official Xinhua news agency said, citing Beijing's work safety bureau.
Two of those firms were shut after inspectors found they did not meet appropriate safety standards.
