Vitaly Khotsenko, acting governor of Omsk Oblast, confirmed that two people had been injured and claimed that the situation was under control.
Khotsenko said the circumstances of the fire were still being investigated.
Russia's Emergency Situations Ministry said that 27 first responders and seven pieces of equipment were dispatched to the scene of the explosion.
The state-run media outlet TASS said that the two injured were being treated on the scene. At the same time, the Baza Telegram channel claimed that both were in serious condition.

Omsk is located in central Siberia, north of the Kazakh border. The city of more than 1 million people is some 3,000 kilometers (~1,860 miles) east of Ukraine.
Over the last year, Ukraine has escalated attacks against Russia's oil industry, successfully reducing the processing capacities of multiple facilities.
