The fire happened at the nitric acid factory. The fire was contained inside the plant and there weren't any human injuries or environmental incidents. Other buildings in the area remained safe and the two other nitric acid plants at the area continue production normally. The fire caused production interruptions that will last approximately ten weeks according to preliminary estimates. The incident cannot be evaluated more closely at the moment.
