Compressed Gas Assoc issued Safety Regulatory alert nov 1, 2019 regarding counterfeit propane cylinders from thailand reports the propane industry's trusted source for news since 1939. (November 11, 2019) — The Compressed Gas Association (CGA) and the Pipeline and Hazardous Materials Safety Administration’s (PHMSA) recently issued a Safety Advisory Notice to inform the public, industrial gas stakeholders, and relevant government officials, of the risks associated with requalifying, filling, and transporting cylinders bearing the DOT specification markings ‘‘DOT 4E’’ or ‘‘DOT 4BA’’ that were produced by a company located in Thailand by the name of Metal Mate. Metal Mate does NOT have an approval from PHMSA to manufacture cylinders to DOT specifications; therefore, cylinders marked with the Metal Mate name are not DOT specification cylinders.

These cylinders must NOT be used to transport hazardous materials in commerce to, from, or within the United States, or on a United States-registered aircraft. These cylinders may not perform to the marked DOT performance standard and may not be safe for commercial transportation or consumer use.

A copy of this Safety Advisory Notice can be found in the Federal Register on pages 58829-58830. The RA-220 is available on CGA’s website at:
