“According to preliminary data, today, around 9 o’clock in the morning at an industrial site of one of the city’s enterprises, an underground oil storage tank was ignited,” the UK said.

According to investigators, a fire could have occurred during welding. Five victims aged 22 to 35 years were hospitalized with burns of varying severity.

An investigator works on the spot. As part of the audit, it is planned to establish all the circumstances, causes and conditions of the incident.

Earlier, the prosecutor’s office also began an audit in connection with an emergency at a tank farm in Novorossiysk.
