In another chemical accident in China following the deadly Tianjin blasts, seven workers at a paper mill in the Hunan province were killed after they were exposed to poisonous gases. 

One of the workers reportedly fell into a pool of waste paper pulp filled with chemical gases, and several of his co-workers rushed to save him. 

However, many of them were killed by the exposure to the poisonous gases, China's Xinhua news agency reported. 

The incident occurred at  11 a.m. local time on Friday. 

The accident comes just weeks after nearly 150 people were killed following deadly blasts at a chemical warehouse in the Tianjin port city earlier this month. 

Several people still remain missing following one of China's deadliest industrial accidents.
