From chemicals killed three workers chemical and metallurgical plant, where the accident occurred. In addition, the hospital — with varying degrees of poisoning — were sent about 20 employees of the plant, two of whom were in the intensive care unit.

According to some data, the substance that caused the tragedy in the titanium plant as mentioned above, chlorine was not. However, the official version of what happened in any city hall Berezniki, nor in the «VSMPO-Avisma» or the MOE reporters until sounded.
