According to TASS, the explosion occurred during the dismantling of a technical pipeline. The publication notes that there was no fire after the explosion at the plant. RIA Novosti notes that at the time of the explosion, equipment was being repaired in the plant's workshop.

One employee of the plant was injured. He has burns on 90% of his body. Earlier this month, an explosion occurred at a plant in Sergiev Posad. Two workers were killed.
