Rules change for LP tank recertification

In October 2014, Pipeline and Hazardous Materials Safety Administration (PHMSA) was taking action to raise awareness of the hazards associated with compressed gas cylinders following a large propane cylinder rupture on a food truck in Philadelphia that resulted in deaths and injuries.

PHMSA focused, in part, on the basics of how to inspect a cylinder for serviceability, and how to identify an out-of-test cylinder. Companies that fill propane cylinders play an important role in ensuring that cylinders are in safe and serviceable condition, the agency noted.

Requalification changes for cylinders were adopted Jan. 21, and PHMSA published a final rule in the Federal Register, titled “Hazardous Materials Adoption of Special Permits (MAP-21)(RRR)” under Docket No. PHMSA-2013-0042(HM-233F).

This final rule incorporated longstanding Department of Transportation special permits into the hazardous materials regulations. As a result, cylinders must be requalified by proof pressure or volumetric expansion testing every 10 years instead of every seven or 12 years.

To aid in increasing awareness, PHMSA also created a short safety video available on YouTube that details the required markings on a cylinder, as well as illustrates how markings indicate when the cylinder must be requalified.

Additionally, free, updated cylinder safety posters noting the new requalification date requirements are now available the PHMSA website.
