UPDATE 4/19/24 - Only tanks with serial numbers starting with a 6 need to be tested.
BISMARCK, N.D. – Anhydrous ammonia nurse tank owners are urged to check the manufacturer and manufacture date of their nurse tanks after a safety advisory was issued by the Federal Motor Carrier Safety Administration and the Pipeline and Hazardous Materials Safety Administration about the possibility of catastrophic tank failure. Tanks made by the American Welding and Tank (AWT) Company in Fremont, Ohio, between Jan. 1, 2007, and Dec. 31, 2011, have had integrity issues with the welding and may rupture.
“Nurse tank owners are urged to check the nameplates on their tanks to see if their tank was manufactured by AWT between 2007 and 2011,” Agriculture Commissioner Doug Goehring said. “If your tank fits this description, please have your tank inspected and cleared before use as they have had continuing problems and have catastrophically ruptured in the past.”
A list of companies that test nurse tanks may be found at www.ndda.nd.gov/nursetanks.
The safety features on all anhydrous ammonia nurse tanks should be checked regularly to ensure they haven’t expired, and all required safety equipment should be readily available.
