Specifically, you ask about the appropriate packaging for a\nshipment by air of ethylene oxide and propylene oxide mixtures, with not more than 30 percent ethylene\noxide, Class 3, UN 2983, PG I.\nYou propose to package your material in a combination package that consists of 5-liter plastic bottles\ncontained within a 1A2 steel drum with a 4-mil polyethylene liner. You note that the inner packaging\ndoes not meet the hydrostatic pressure requirements for air shipment, as required by § 173.27(c)(ii) of\nthe HMR.\nFor transportation by aircraft, the outer packaging of a combination packaging containing inner\npackages of a PG I liquid product is not required to meet the 250 kPa (36 psig) test pressure\nprescribed in § 173.27(c)(3)(ii). Section 173.27(c)(3)(ii) only applies to single and composite\npackages intended to contain liquids. Combination packages are not subject to the hydrostatic\npressure test and marking requirements of §§ 178.605 and 178.503(a)(5) respectively. Section\n173.27(c)(2) requires that packages for which retention of liquid is a basic function must be capable of\nwithstanding without leakage an internal pressure based on the vapor pressure of the material to be\ntransported. Section 173.27(c)(3)(i) allows inner packages that are not capable of meeting the\npressure requirement to be placed in a supplemental packaging that meets the pressure requirements.\nNote that, although § 171.8 of the HMR includes separate definitions for \"inner packaging\" and \"inner\nreceptacle\" the terms are used interchangeably throughout the HMR and are not interpreted to be\ndifferent items.\nI hope this information is helpful. Please contact us if you require additional assistance\nSincerely,\nSenior Transportation Regulations Specialist\nOffice of Hazardous Materials Standards\n173.27\n030163\n\n<<<PAGE 2>>>\n\nRelerford\nDEFENSE LOGISTICS AGENCY\nDEFENSE DISTRIBUTION CENTER\n$173.27\nNEW CUMBERLAND, PA 17070-5000\n2001 MISSION DRIVE\nPackaging\nIN REPLY\nREFER TO\n03-0163\nDDC-J-3/J-4-O\nJUN 2 6 2003\nSTANDARDS\nMEMORANDUM FOR DOT, RSPA, OFFICE OF HAZARDOUS MATERIALS\nSUBJECT: Request for Interpretation, 49 CFR 173.27\nappropriate for the contents below.
