PHMSA-2011-0241 (Notice No. 11-10): Safety Advisory: Unauthorized Marking of Compressed Gas Cylinders

SUMMARY: This notice advises the public that PHMSA has recently confirmed the marking and sale of certain high pressure DOT specification cylinders that were marked with a requalification identification number (RIN) without performing a visual inspection and hydrostatic test.  An undetermined number of high pressure DOT specification cylinders were improperly marked from approximately August 2007 to August 2011 and marked with a RIN of B377.  The evidence suggests that if a cylinder purchased from Morgan Welding and Supply, Albion, Michigan is marked with a "B377" in which the individual letter and numbers appear to be stamped individually, the mark may have been improperly placed on the cylinder. The cylinder did not undergo the complete series of safety tests and inspections required by the HMR and may not possess the structural integrity to safely contain its contents under pressure during normal transportation and use.
