BFE was found to have marked approximately 5,900 high pressure compressed gas cylinders with test dates and Requalifier Identification Number (RIN) H557 in 2011 and 2012 without conducting the prescribed hydrostatic testing of these cylinders. PHMSA has terminated the RIN Approval H557 issued to BFE. These cylinders should be considered unsafe and not authorized to be filled with hazardous material. Please read this safety advisory for more details should you have a cylinder stamped with the RIN H557 with a test date in 2011 or 2012.
