Pipeline and Hazardous Materials Safety Administration March 9, 2005 – Federal Register Recent Federal Regulation Documents

PHMSA proposes to amend the Hazardous Materials Regulations (HMR) to adopt standards for the design, construction, maintenance and use of cylinders and multiple-element gas containers (MEGCs) based on the standards contained in the United Nations (UN) Recommendations on the Transport of Dangerous Goods. Aligning the HMR with the UN Recommendations will promote flexibility, permit the use of technological advances for the manufacture of pressure receptacles, provide for a broader selection of pressure receptacles, reduce the need for exemptions, and facilitate international commerce in the transportation of compressed gases.
