Shanghai has launched widespread work safety inspections in the wake of massive explosions in a warehouse in north China's Tianjin last Wednesday.
Yesterday, the death toll from the blasts reached 112, with 95 people missing and more than 700 people hospitalized.
In the city, inspections are targeting enterprises involved in the production, operation, storage and transport of hazardous chemicals, inflammable materials and explosives, Shanghai's vice mayor, Zhou Bo, said at a work safety meeting on Saturday.
Inspections aim to achieve "full coverage, zero tolerance, strict enforcement and be performance oriented", said Zhou.
Locations include residential areas, public places, ports, airports and other transit stations, plus oil and gas storage sites.
Inspectors will ensure that supervision of hazardous chemicals adheres to regulations and that information is shared among institutions, said officials.
Where dangers are uncovered, enterprises must take immediate action, said officials.
The city meeting followed a meeting by the State Council's Work Safety Commission, also on Saturday, instructing provinces and cities to conduct checks.
Shanghai's work safety watchdog reported on its website that it has conducted two surprise inspections since the Tianjin blasts.
Sunriow, a logistics company based in the Pudong New Area which stores combustible and toxic materials, including essences and fragrances, was found to be storing products improperly under required categories.
And issues were found with Givaudan Fragrances (Shanghai), a Swiss manufacturer of flavors and fragrances, including excessive quantities of hazardous chemicals.
They have been told to rectify these problems, and Givaudan, based in Chuansha in Pudong, faces a follow-up inspection, said the watchdog.
The city's fire department has also conducted inspections.
On Friday, inspectors went to Shanghai NRS-Norinco, a logistics company at Yanghao Rd, in Lingang Area in Pudong, that stores condensed gases, such as chlorine and ammonia.
It was found that one warehouses was managed by a company renting the warehouse, which is against regulations.
Central government said it will publish a report of findings from across the country by mid-September.
