As of 7am, more than 170 injured people, including 24 seriously injured, were receiving medical treatment in hospitals.
The injured also include seven children, two of whom are in a severe condition, but none of them face life-threatening injuries.
The Zhejiang provincial health commission dispatched 62 medical experts to Wenling to help with the rescue and treatment of the patients, including two from the Children's Hospital of Zhejiang University School of Medicine.
Experts said that most of the child patients were injured by flying glass or hard objects in their homes. One had an eye badly hurt while another suffered a lung injury from the explosion.
The accident occurred at around 4.40pm on Saturday when a tank truck, loaded with liquefied petroleum gas, exploded near a village in Wenling on a section of the Shenyang-Haikou Expressway.
A second blast soon followed. The explosions caused the collapse of nearby residential buildings and factory workshops.
The large-scale search and rescue work at the scene has mostly been completed. - Xinhua/Asian News Network
