On Thursday April 4th at 2:30 PM the Roseville Fire Department’s Hazardous Materials team responded to the Union Pacific Railyard for a tankcar leaking a very powerful acid.
The railcar’s rubber lining had been compromised and the acid had eaten through the tanks steel shell. When crews arrived they found a 1 gallon per minute leak from the bottom of the car which required plugging.
The product was Ferric Acid which is a commonly used chemical in industry for water treatment and other uses. The railcar was loaded with 16,000 gallons of the product, however hazmat crews were able to stop the leak before a major release occurred, saving most of the product.
The damaged railcar will remain in the Roseville railyard until it can be safely offloaded into another highway rail tanker.
Because of the corrosive properties of the product, crews were required to wear protective equipment before entering the area to plug the leak. The operation took several hours to complete. There were no injuries to civilians or first responders.
