No. 1O~0144\nDear Mr. Weberg:\nThis responds to your letter requesting clarification of the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180) applicable to overpack marking and labeling requirements.\nSpecifically, you ask if clear shrink-wrapped pallets must be marked on the outside with the\nrequired package markings (e.g., proper shipping name, identification number, orientation arrows,\nand \"OVERPACK\") when the markings on individual packages are not visible because of the\npackage configuration, but markings and labels representative of each hazardous material are\nvisible from the outside of the overpack. Your areas of concern are restated and answered as\nfollows:\nLabels and Proper Shipping Namelldentification Number Markings\nSection 173.25(a)(2)of the HMR requires the overpack, as defined in § 171.8, to be marked with\nthe proper shipping name and identification number, when applicable, and labeled for each\nhazardous material contained therein, unless markings and labels representative of each hazardous\nmaterial in the overpack are visible. For example, an overpack need not be marked and labeled if\nthe markings (i.e., proper shipping name and identification number) and labels on an individual\npackage inside the overpack are not visible but the same markings (i.e., proper shipping name and\nidentification number) and labels representative of that package are clearly visible from the\noutside ofanother package contained in that overpack.\nOrientation Arrow Marking\nSection 173.25(a)(3) of the HMR requires an overpack containing packages subject to the\norientation arrow marking requirements of § 172.312 to be marked with orientation arrows on two\nopposite vertical sides of the overpack with the arrows pointing in the correct direction of\norientation. This requirement is in addition to the orientation arrows displayed on the individual\npackages.\n\n<<<PAGE 2>>>\n\n\"OVERPACK\" Marking\nSection 173.25(a)(4) of the HMR requires an overpack to be marked \"OVERPACK\" when\nspecification packagings are required, unless specification markings on the inside packages are\nvisible. The \"OVERPACK\" marking is not required if the overpack contains multiple packages\nwith identical package specification markings provided a package specification marking\nrepresentative of each package specification contained in the overpack are visible from the\noutside.\nHazardous Materials Packaged with Non-Hazardous Materials\nAs prescribed in § 173.25(a)(1) of the HMR, packages may be placed inside a larger package or\naffixed to a pallet that also contains other compatible hazardous and non-hazardous materials.\nThe overpack must be marked and labeled for each hazardous material contained therein unless\nmarkings and labels representative of each hazardous material in the overpack are visible.\nMixed Contents\nHazardous materials may be packaged together with other hazardous and non-hazardous materials\nas prescribed in §§ 173.24(e)(4) and 173.21(e) of the HMR. For example, such determination is\nbased on whether or not the mixing of a material in the same packaging, freight container, or\noverpack with another material is likely to cause a dangerous evolution of heat, or flammable or\npoisonous gases or vapors, or to produce corrosive materials.\nSegregation\nUnder the HMR, the segregation requirements for transportation by highway specify that a\nhazardous material may not be loaded, transported, or stored together except as provided in\n§ 177 .848( d) of the HMR. For example, cyanides or cyanide mixtures may not be loaded or\nstored with acids if a mixture of the materials would generate hydrogen cyanide (See 49 CFR\n177.848(c)).\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\nT.

Weberg [mailto:rkweberg@mcpur.com]\nSent: Tuesday, June 29, 2010 10:31 AM\nTo: INFOCNTR (PHMSA)\nCc: Rollie K. Weberg; David M. Roelofs\nSubject: Questions on L TL Haz-Mat truck shipments\nHello, and thank you for our opportunity to discuss our questions in written form.\nWe are writing our company's work instruction for shipping hazardous materials via, truck - L TL.\nWe tried to put into writing what we have been doing, and what we has been told to us via phone discussions wI other\nDOT advisors,\nWe would like to get a final ruling on some of this information. We have our own thoughts on the interpretation, and then\nwhen we call in to DOT to discuss, there are times over the years that we get different answers because of differing\ninterpretations of even the DOT advisors. .\n---------------------------------------------------------\n---------------------------------------------------------\nWe have a question concerning Labeling a L TL truck shipment:\nThe following is what we have been told and we have written it this way:\n\"At least one box displaying all applicable Haz-Mat labels, and one box displaying the Spec.\nPackaging information of any/every different kind of hazardous material must be visible on each\npallet - if stretch-wrapped, the information must be legible through the stretch wrap.\"\nIs this true or false? How do we need to change for correct interpretation?\n---------------------------------------------------------\n---------------------------------------------------------\nWe have a question concerning Haz-Mat Packed on Pallet with Stretch Wrap:\nThe following is what we have been told and we have written it this way:\n\"You may place one or more (several different kinds) Haz-Mat packages (different UN numbers) on\nthe same pallet as long as they are in the same chemical compatibility group (49 CFR173.81).\n• i.e. - Gallon and quart boxes of the same product (same UN #)\nmay be packed together - labels must tie seen from at least one\nside of the pallet.\n• i.e. - Two (or more) different types of the same Class may be\npacked together - labels must be seen from at least one side of\nthe pallet.\n1\n\n<<<PAGE 4>>>\n\n• i.e. - Haz-Mat may be packaged along with non Haz-Mat\npackages - labels must be seen from at least one side of the\npallet.\n• The stretch wrap needs to be transparent - Haz-Mat may not be\nconcealed in a box or concealed with colored stretch wrap or it is\nconsidered to be an \"Overpack. \"\nIs this true or false? How do we need to change for correct interpretation?\n---------------------------------------------------------\n---------------------------------------------------------\nWe have a question concerning Haz-Mat Overpacks:\nThe following is what we have been told and we have written it this\nway:\n\"It is considered to be an \"Overpack\" when Haz-Mat is concealed\ninside another box (ie. gaylord). or when pallet is stretch wrapped\nwith material that disallows the labels to be clearly legible through\nthe wrap.\n• If the above conditions exist, the word \"OVERPACK\" must be\napplied directly to the box - not on the stretch-wrap.\nIs this true or false? How do we need to change for correct interpretation?\n---------------------------------------------------------\n---------------------------------------------------------\nWe have another question concerningHaz-Mat Overpacks:\nThe following is what we have been told and we have written it this\nway:\n\"You may pack one or more (several different kinds) Haz-Mat packages\nwith different UN numbers in the same box/gaylord as long as they are\nin the same chemical compatibility group (49 CFR173.81).\n• i.e. - Gallon and quart boxes may be packed together in the\ngaylord.\n• i.e. - Two (or more) different types of Class 8 may be packed\ntogether in the gaylord.\n• Le. - Haz-Mat may be packaged along with non Haz-Mat packages\nin the gaylord.\nWe are stating that all this may happen if the shipper documents on\nthe BOl exactly what they have inside the gaylord, and if they have\nappropriately labeled the proper Haz-Mat labels on the outside of\nthe gaylord.\nIs this true or false? How do we need to change for correct interpretation?\n---------------------------------------------------------\n---------------------------------------------------------\nThank you for your time and attention on these questions.\nSincerely,\nRollie Weberg\n2\n\n<<<PAGE 5>>>\n\nSkippack Operations Manager\nMAR COR PURIFICATION\nA Cantel Medical Company\n4450 Township Line Road,\nSkippack, PA 19474\nP - 484-991-0220\nF- 484-991-0230\nrkweberg@mcpur.com\nThis communication (including any attachments) is intended only for use by\nthe addressee(s) named herein and may contain legally privileged or confidential\ninformation.
