According to specialists, gas condensate is a particle set free from natural gas that appears as a mixture of high-boiling liquid carbohydrates. Gas condensate is raw material for producing motor fuel and is also used in chemical industry. When it contacts the environment, a quick evaporation of high volatile particles of gas condensate occurs, and its toxicity declines. The remaining compounds partly dissolve in water and undergo processes of physic-chemical and biological destruction.
According to the preliminary version of the prosecutor’s office, the fire was caused by the contact system breakage.
About 700 people were evacuated from the area of the accident.
