A man in his fifties was rescued from the Tianjin blasts site on Saturday afternoon.
Specialized anti-chemical soldiers found him 50 meters away from a burst point.
The man was conscious and could talk when rescued. He was rushed to a hospital in the city.
The man suffered from respiratory tract burn but was in a stable condition after emergency treatment, said Li Jingmei, a doctor from the No.254 hospital in Tianjin.
A total of 70 specialised anti-chemical soldiers entered the core area of the blasts site on Saturday morning to search for possible lives.
The warehouse blasts, which occurred late Wednesday night, killed at least 85 people, including 21 firefighters. At least 721 were injured.
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 centre of containers of dangerous goods at the Tianjin Port.
