BEIJING, Aug. 14 -- Beijing has ordered inspections of all manufacturers or enterprises that deal with dangerous goods after a fatal blast at a warehouse in Tianjin on Wednesday.

The city's work safety department will inspect all manufacturers and explosive-product enterprises, said Zhang Yankun, Beijing vice mayor, on Thursday.

In preparation for the military parade on Sept. 3 and the Athletics World Championships from Aug. 17 to Sept.6, production and operation at these companies and plants will be suspended. All toxic chemicals must be sealed, stored and guarded by designated personnel, the vice mayor added.

The work safety department also ordered all enterprises in the capital to strengthen safety measures against thunder, fire and explosion.

The State Council, China's cabinet, issued an emergency notice on Friday that instructed governments at all levels to review the management of dangerous chemicals and explosives and to firmly implement special regulatory measures for highly toxic chemicals such as cyanide, as well as inflammable and explosive materials.

The warehouse blasts, which occurred late Wednesday night, killed at least 56 people, including 21 firefighters. A total of 721 were injured, of whom 25 are still in critical condition.

The warehouse was owned by Tianjin Dongjiang Port Rui Hai International Logistics Co. Ltd., which was founded in 2011 and is a storage and distribution center of containers of dangerous goods at the Tianjin Port.
