North China's Tianjin has learned a harsh lessons from the warehouse explosions that killed 165 people in August.
According to a directive issued earlier this month, companies that produce, store or use dangerous chemicals must complete a reclassification and safety assessment of their "major sources of danger" and report the information to local authorities by the end of March.
The statement also ordered the companies' own security systems be integrated into government platforms by the same deadline.
In addition, the companies should have contingency plans and conduct at least two drills a year.
On Aug. 12, two explosions ripped through a Ruihai Logistics' warehouse in Tianjin Port. Eight people are still unaccounted for.
After five months of investigation, a State Council investigatory team concluded that the disaster, "an extraordinarily serious production safety accident," was caused by ignition of hazardous materials, improperly or illegally stored at the site.
It identified 123 people as responsible for the explosions. The company's executives were found to have exploited their connections and bribed local officials to obtain approval.
