A plant fire in central China's Hubei Province was under control on Wednesday afternoon as authorities are checking the casualties and losses.

The fire broke out on the fourth floor of a five-story workshop building at the Tuochuang industrial park in Wuhan, capital of Hubei, at 4 p.m. Wednesday.

Twenty-four fire engines with more than 100 firefighters rushed to the scene to quench the blaze. Witnesses told Xinhua they heard sounds of blasts and saw workers jump from the building.

Butane and cables fueled the fire, firefighters said after an initial probe.

Authorities are calculating the number of casualties and losses.
