One person died and three were injured on Thursday afternoon when a house exploded in Napo town in the Tianyang district of Baise, Guangxi Zhuang autonomous region, local authorities reported.
The explosion was attributed to thermal expansion materials stored at a rented house. The materials were purchased on Saturday by a man surnamed Deng, a tenant of the house, and were to be used in road repair work, the authorities said.
At 6 pm on Thursday, the materials exploded, resulting in four casualties at a neighboring automobile repair shop. The blast also damaged several vehicles and houses. Property loss is estimated to be 500,000 yuan ($77,400).
All the injured people have received medical treatment and vital signs are stable, the authorities said.
Similar potentially explosive materials are being sought for inspection across the district.
