About 2,000 tonnes of gasoline has leaked from a broken pipe after an accident at a construction site on Tuesday night in southwest China's Guizhou Province, said rescue workers on Wednesday.
The leak started at about 0:40 Wednesday from a broken gasoline pipe after a construction tower collapsed late on Tuesday night at a high-speed railway construction site in Pingba County of Anshun City, said rescuers.
The pipe belongs to a branch of the country's largest oil refinery Sinopec.
Three people have received medical treatment, and more than 110 are working to repair the broken pipe and clear the site, about 30 meters from the Shanghai-Kunming railway, with residential houses nearby.
The local government has taken emergency measures to stop the leak and evacuate residents from within a two kilometer radius. Rail authorities have suspended train services from Anshun to the provincial capital of Guiyang.
A provincial joint investigation team has been formed to look into the accident, and safety inspections are being carried out across the province.
