A fire at the Magnitogorsk Iron and Steel Works [RTS: MAGN] in the city of Magnitogorsk in Russia's Urals broke out in a rolling section November 28, engulfing an area of about 1,200 square meters (13,000 square feet) and causing part of the roof to collapse, killing eight people and injuring 10.
The Federal Service for the Oversight of the Environment, Technology and Nuclear Management said Thursday the state commission investigating the incident had not discovered any violations of the standard technological cycle.
A short circuit has also not been ruled out, and the commission has established that polypropylene used in the plant's pickling section caught fire. The watchdog also said the collapse of the roof was caused by the deformation of the building's load-bearing frames due to the extremely high temperatures caused by the fire.
Earlier it was reported that human error might be to blame for the accident, as technical reasons had been ruled out.
