This is stated on the website of the UK.
According to the investigation, an agreement was signed with the owners of the two apartments on the maintenance of gas equipment.
At the same time, the general director of the company did not organize the appropriate maintenance and did not reveal a malfunction of the gas equipment.
As a result, there was a large leak of domestic gas in one apartment, and due to the lack of packing between the gas pipe and the floor of the apartments, improper functioning of the ventilation system, the domestic gas was concentrated in another apartment.
“These circumstances led to the cotton of concentrated household gas and to the complete collapse of the first four floors of the second entrance of the house,” the UK said.
On September 9, EMERCOM employees completed rescue operations at the site of a gas explosion in a multi-storey building in Noginsk near Moscow.
As a result of the emergency, seven people died, 22 were injured.
