[Docket No. PHMSA-2011-0241, (Notice No. 11-10)]


Safety Advisory: Unauthorized Marking of Compressed Gas Cylinders

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA), 
DOT.

ACTION: Safety Advisory Notice.

-----------------------------------------------------------------------

SUMMARY: 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.
    Prior to filling these cylinders, a person must verify that the 
cylinder has been properly requalified by an authorized requalification 
company and properly marked.

FOR FURTHER INFORMATION CONTACT: Morgan Welding and Supply, Mr. Daniel 
Horosko, Owner or Mr. Matthew Stepps, Manager, 488 Finley Road, Albion, 
MI, Telephone (517) 629-6566.

SUPPLEMENTARY INFORMATION:
    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. The 
company that marked the cylinders does not have authority from the 
Associate Administrator to requalify high pressure DOT cylinders. 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 Hazardous Materials Regulations (HMR) and may not 
possess the structural integrity to safely contain its contents under 
pressure during normal transportation and use. Extensive property 
damage, serious personal injury, or death could result from a rupture 
of the cylinder. Individuals who identify a cylinder marked with the 
RIN ``B377'' stamped with individual letter/numbers that are not in a 
square pattern, are advised to remove these cylinders from service and 
contact Morgan Welding and Supply, Albion, MI for further instructions.
    However, the RIN ``B377'' is currently authorized to Midwest 
Cylinder Inc., located in Cleaves, OH. Cylinders purchased from Midwest 
Cylinder Inc. will have the proper RIN ``B377'' and have been properly 
requalified. Cylinders from Midwest Cylinder Inc. can also be 
identified by blue paint highlighting the requalification markings. The 
RIN, ``B377'' has been stamped on the cylinder with a square pattern 
stamp so the marks will appear uniform and straight.

    Issued in Washington, DC, on November 4, 2011.
Magdy El-Sibaie,
Associate Administrator for Hazardous Materials Safety.
