An explosion killed two workers and injured 26 others at a food dye factory in Wuhan, capital of Central China's Hubei province, on Tuesday.

A three-story workshop collapsed following the blast at 1:24 pm at Wuhan Lucheng Biotechnology in the city's Jiangxia district.

Video footage from a surveillance camera shows a ball of fire bursting through the building's roof scattering debris into the air. Shortly afterwards, a man is seen running out of the workshop.
