It was a small incident in a heat-electric power plant. The alarm was registered at 11:26 and the fire was extinguished at 12:03. The incident took place during tests using the reserve power generator, thus it did not affect the operation of the main power plant. Officials stated that the incident took place because hydrogen and motor oil on the engine rotor ignited.

The incident took place in a calcium powdered wire manufactory of "Chepetsk Mechanical Plant". Some amount of water find it's way in a container where the mixing of different powders took place. As a result of chemical reaction active evolution of hydrogen occurs which results in accidental explosion from a spark. The explosion caused 5 injuries and 4 fatalities.

Huge explosion of liquid chlorine mixed with hydrogen took place on pulp and paper plant in Arkhangelsk. More than 50 tons of liquid chlorine exploded.
