The plant is located on Zolotorozhski Val Street, building 11. The fire alarm signal was received at 2.50 p.m. (MST). The fire has been given the third degree on a five-degree scale. As a result of the fire, about 400 square meters of the roof have partially collapsed.

Clouds of black smoke rising from the building are seen from a distance of several kilometers, RIA Novosti correspondent reports from the site.
