MOSCOW, February 17 (RIA Novosti) – Rescuers are working to contain a sulfuric acid leak from cisterns which derailed at a copper plant in the Russian Urals Sverdlovsk region on Sunday.

“The sulfuric acid leak area is 100 square meters,” Russia’s Emergencies Ministry said. The accident has not affected the work of the plant, it said.

A total of 12 cisterns derailed at the plant. Only two cisterns were filled with sulfuric acid, local emergencies services said.

Some 27 rescuers and 57 workers of the Sredneuralsk Copper-Smelting Plant at Revda are involved in the effort to contain the leakage.
