April 29, 2015: (SA) Hazardous Materials Safety Advisory – Unauthorized Certification of Compressed Gas Cylinders

PHMSA has issued a safety advisory concerning Liberty Industrial Gases and Welding Supplies Inc., also known as Liberty Industrial Gases and Welding Supply, Inc., located in Brooklyn New York. Liberty Industrial marked ICC, DOT Specification and DOT Special Permit high pressure compressed gas cylinders as authorized for hazardous materials transportation. They did not, however, properly test the cylinders and do not have authorization to do so.

If any of these cylinders have been taken or received from Liberty Industrial Gases and Welding Supplies any time between April 1998 and October 2014 they may not have been tested properly as required by the HMR. They are not authorized for filling of hazardous materials until they have been properly tested by an  individual or company who has been authorized to re-qualify DOT Specification and DOT Special Permit cylinders.

Cylinders described in this safety advisory notice that are filled with atmospheric gas should be vented or otherwise safely discharged. Cylinders that are filled with a material other than an atmospheric gas should not be vented but instead should be safely discharged.
