In its continued efforts to support the need to move critical hazardous materials products during the COVID-19 public health emergency, PHMSA will impose an enforcement discretion for cylinders that have exceeded their periodic requalification test dates.  PHMSA understands that due to the COVID-19 emergency, many members of the medical and industrial gas industry may be experiencing difficulty in obtaining cylinders due to the increased demand for these gases or a disruption in the normal business model for cylinder exchanges. The Notice in the related documents section of this page, provides notice that PHMSA and the Federal Motor Carrier Safety Administration will not take enforcement action against any person who fills a DOT-specification cylinder used to transport Division 2.2 non-flammable gas by motor vehicle.  The enforcement discretion does not extend to transport by air, vessel, or railroad.  

For more information, see the Notice of Enforcement Discretion for Cylinders in the related documents section of this page.
