PHMSA is issuing this safety advisory to notify the public of the unauthorized marking of high pressure compressed gas cylinders. Investigators from PHMSA’s Office of Hazardous Materials Safety (OHMS) recently conducted a compliance inspection of George Welding & Supply Co., Inc. As a result of that inspection, PHMSA has determined that George Welding & Supply Co., Inc. marked an unknown number of high pressure compressed gas cylinders with unauthorized Requalifier Identification Numbers (RIN). In addition, the evidence suggests that George Welding & Supply Co., Inc. marked and certified an unknown number of high pressure compressed gas cylinders as being properly requalified in accordance with the Hazardous Materials Regulations (HMR) when it had not conducted the testing prescribed by the HMR. PHMSA has no record that George Welding & Supply Co., Inc. was ever approved to requalify DOT-specification cylinders or mark such cylinders as being requalified.
