BEIJING - China has ordered local authorities to better manage hazardous chemicals and ensure workplace safety following a fatal chemical plant explosion earlier this month, the Ministry of Emergency Management said Friday.

The incident happened during maintenance at the plant's alkylation facility in Liaoning's Panshan County on Jan 15, leaving 13 dead and 35 injured.

The initial investigation exposed significant flaws in the safety management of the plant's high-risk operations, and that for a long time, hidden hazards had not been completely eliminated, the ministry cited a statement from the Work Safety Committee of the State Council as saying.
