DC 20590\nPipeline and Hazardous\nMaterials Safety\nAdministration\nAUG 122011\nMr. A. Gam Butcher\nExplosives Safety Specialist\nSafety Management Services Inc.\n1847 West, 9000 South, Suite 201\nWest Jordan, UT 84088\nReference No.: 11-0122\nDear Mr. Butcher:\nThis responds to your May 25, 2011 letter requesting clarification of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) applicable to UN 3366,\n\"Trinitrotoluene (TNT), wetted, with not less than 10 percent water by mass,\" and\nUN 1356, \"Trinitrotoluene wetted or TNT, wetted, with not less than 30 percent water by\nmass.\" Specifically, you ask whether these materials are Division 4.1 (Flammable solid)\nmaterials, and can be transported without an EX number. You also request clarification of\nthe packaging authorized by the HMR for these materials.\nUnder § 173.22, it is the shipperfs responsibility to class and describe a hazardous material.\nThis Office does not normally perform this function. However, you are correct in your\nunderstanding tha.t these materials are both Divis~on 4.1 materials, and do not require an\nEX number. In accordance with § 173.124(a)(1)(ii), materials properly classed as\ndesensitized mixtures of explosive materials and specifically listed in the Hazardous\nMaterials Table (§ 172.101), in this case UN 3366, \"Trinitrotoluene (TNT), wetted, with\nnot less than 10 percent water by mass,\" and UN 1356, \"Trinitrotoluene wetted or TNT,\nwetted, with not less than 30 percent water by mass,\" may be transported as Division 4.1\nmaterials and do not require an EX number. Please note that some of the special\nprovisions assigned to each of these materials are in error in the HMR. Special Provision\n23 should apply to UN 3366, not UN 1356. In addition, as specified in the HMT for both\nof these materials, please refer to § 173.211 for approved non-bulk packaging.\nI hope this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\nT. Glenn Foster\nChief, Regulatory Review and Reinvention Branch\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nI+ndre{JJs\nDrakeford, Carolyn (PHMSA) ~ I7Z· I0 ,\nFrom: Betts, Charles (PHMSA) Propp,- &, ippl fJj Name\nSent: Thursday, May 26, 2011 4:50 PM\nTo: Drakeford, Carolyn (PHMSA) 1 I 'l'\\\nCc: Andrews, Steven (PHMSA); Foster, Glenn (PHMSA) - U 12'2.\nSubject: FW: Flammable solid TNT\nPlease log in this new request for interpretation and assign to Mr. Steven Andrews.\nThanks,\nCharles\nFrom: Watson, Spencer (PHMSA)\nSent: Thursday, May 26, 2011 3:55 PM\nTo: Betts, Charles (PHMSA); Pfund, Duane (PHMSA); Boyle, Rick (PHMSA); Ke, Charles (PHMSA); Vos, Brian (PHMSA);\nNicklous, Joseph (PHMSA); Singh, Harpreet (PHMSA)\nCc: Butcher, Garn\nSubject: FW: Flammable solid TNT\nCharlesGarn's\nquestion I believe should be addressed officially by Standards. Nowj there are two 172.101 table entries for TNT,\nwetted with 30% water (1356) and 10 % water(UN3366), both as 4.1. One takes SP 162 and the other takes SP 23. ,Jthi\nk there's a mix-u in hos ou h. think the 10% wetted TNT should take the SP 23 and the 30%\nshould take SP 162, . hich would agree with the UN Model regulations that there's an im osed 500 ram maximum for\n10 percent water wet TNT. In either case, however, I believe t ey don't need an approval to ship first .\n•\n______.~\"'..::to\nSpence Watson\nUSDOT/PHMSA- PHH21\n1200 New Jersey Ave S.E.\nWashington, DC 20590\n(202)366-8830 - Phone\n(240) 285-3503 - Mobil\nFrom: Garn Butcher [mailto:gbutcher@sms-ink.com]\nSent: Wednesday, May 25, 2011 5:27 PM\nTo: Watson, Spencer (PHMSA)\nSubject: Flammable solid TNT\nSpencer:\nHope the meetings with the labs is going well. If you get a chance, I have a question on TNT. I have a client who said\nthat he was told by a burn facility that TNT wetted at 10% with water and packaged in 5-gallon containers is a 4.1\nFlammable solid, and can be sent without an EX number.\nIs this correct?\nDoes the manufacturer still have to apply for a shipping authorization through a testing lab to ship in this configuration as\na4.1?\n(My research says UN3366 is 10% wet, shipped 4.1, pg 1, and UN1356 is 30% wet also shipped 4.1, pg 1, but neither as I\ncan determine specify any container size other than non-bUlk. IF this is true, then can he ship in 55 gallon drums, wet as\n4.1 without any tests?)\n1\n\n<<<PAGE 3>>>\n\nThanks\nGam.\nA.
