Pipeline and Hazardous Materials Safety Administration April 16, 2012 – Federal Register Recent Federal Regulation Documents

PHMSA is amending the Hazardous Materials Regulations to require closures of inner packagings containing liquids within a combination packaging intended for transportation by aircraft to be secured by a secondary means or, where a secondary closure cannot be applied or it is impracticable to apply, permit the use of a leakproof liner. These amendments are consistent with the 2011-2012 edition of the International Civil Aviation Organization Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Technical Instructions).
