Beijing: China's energy watchdog has demanded safety checks on facilities and systems that involve dangerous chemicals or explosives following the deadly Tianjin blasts that claimed 104 lives, media reported on Sunday.

Facilities involved include hydrogen generation stations, ammonia producing systems, fuel tanks, warehouses storing volatile chemicals and explosives, coal pulverizing and natural gas systems, according to a notice issued by the National Energy Administration.

The repeated emphasis on work safety followed the massive explosions at a warehouse storing dangerous chemicals in north China's Tianjin city on Wednesday night, killing at least 104 people and injuring more than 720, Xinhua news agency reported.

The State Council Work Safety Commission said the blasts revealed a lack of safety awareness among businesses, weak emergency response and poor supervision by authorities.
