Box 7922\nCanoga Park, CA 91309-7922\nDear Mr. Mhemedi:\nThis is in response to your August 15, 2000 letter and subsequent telephone conversation with\nMr. Charles Hochman of the Office of Hazardous Materials Technology, requesting clarification\non the packaging requirements for pyrophoric liquids under the Hazardous Materials Regulations\n(HMR; 49 CFR Parts 171-180). Specifically, you have asked if your packaging configuration\nmeets the requirements contained in § 173.181(b).\nYou correctly stated that § 173.181(b) requires \"inner receptacles having positive screwcap\nclosures adequately gasketed\". Based on our review of your design, we agree that the plug and\nretainer used to secure the burst diaphragms meet the screwcap closure requirement and the 300\npsig burst diaphragms meet the adequately gasketed requirement in § 173.181(b).\nI trust this answers your inquiry. If you need additional assistance, do not hesitate to contact us.\nSincerely,\nDelmer F. Billings\nChief, Standards Development\nOffice of Hazardous Materials Standards\n\n<<<PAGE 2>>>\n\nAUG-15 ØØ 13:28 FROM:\nTO: 812023663012\nPAGE: 01\n@BUEING\nJAX\nB833 Canoga Ave.\nThe Boeing Company\nLaValle\nP.O.

Attached are drawings showing our hypergol\ncanister design and the outer can packaging. The hypergol liquid (no more than 6 cubic\ninches) is contained in metal canisters (inner receptacles) which have 300 psig burst\ndiaphragms on both ends; these diaphragms also perform the gasket function and are held\nin place by a retainer on one end and by a plug on the other end, both of which are\ntorqued to more than 500 in-ibs. We consider these plugs/retainers to satisty the\n\"positive screw cap closure\" requirement, but would like your ruling on whether the 300\npsig burst diaphragms meet the \"adequately gasketed\" requirement.\n\"Dixie Model 24 Power Sealer\",\nThe outer metal cans, in which the hypergol canisters are enclosed, are sealed using a\n, or equivalent. Essentially, these cans are sealed like\nsoup cans - a can opener is needed to open them. Cushioning within the outer can and\nwithin the wooden box would be accomplished with Vermiculite.\nIn summary, we would like your assessment of whether our hypergol canister design\nallows us to use wooden boxes (max of 4 canisters per box) for shipment. As this\nshipping query is an urgent matter for us, a quick response would be much appreciated.\n-\nIf we can ship using wooden boxes, we would like to request approval for use of a\nsmaller number of test samples, as is allowed in Title 49 CFR paragraph 178.601. Drop\ntest validity will not be affected by performing the flat top, bottom, and side drops on the\nsame test sample given the configuration of our container. Relief from the number of test\ncontainers would be a financial help in this matter.\nThanks,\nFawzi Mhemedi\n\n<<<PAGE 3>>>\n\nPAGE 2\nRED INK STAMP\nDREGER\n...\n.. -\nKEDAD WITH 82÷15 GRAI\n\"ANEUSED TO ELL'REN\nGH5299\n15-219 PACK)\nEXPORT CONTROLLED PER ITAR\nA\nTO-ZORERO\nSETON\nAA\n8651149: RETAINER\nTORQUE TO.550\nBOSOME A DIAPH\n**:.\nRESOLO: CARTRIDGE, I REÇO\nG\nT65Q44.LRETAINER TREQD :..:\nIORQUE TO 550 1 1N L85 ;\n@DOW CARNING, FSIZE ( ALLOWABLE ALTERNATE.\n5) A LUBRICATE THREADS ARD ZETAINER-TO-DIAPHRAGM\nFOR 2BO 140-012.\n.1.\nBEFRING SURFACES WTH, AEO 140-012 LUZICANT PE2 2\nO.Z WORKATE PER RADIZ-OÇÀ FOR RM-L. 4 HYPERGOL\nMETHOD 'À' FAR THO'S & NETHUD'E FOR RETAINER ZEAZIN\nCTOR LIST OF MATERIAL ALL IM BEATURE\nSERVICE METADO V.?\nBE MENTIFY, PIE RADIOS-DA DO,NOT UNAATESSION\n¿ CORRESPONDINE PART NO SEE IN EE*P•:\n24 TRIETHYLALUMINOM PEZ SPEC NA2O15IG.\nSTAMP\n:: - i:a\nTE ORIENTATION OF DIAPHRAGM: COINED\n2 ACCEPTA ASSEMBLE PER EA0Z1O-315\nSIDE OUT:\nMOLD HOLE\nNOTE: UNLESS OTHERWISE SPECIED,\n1 PACKAGE PER RAZOOTE\n\n<<<PAGE 4>>>\n\nAUG-15 0Ø 13:29\nFROM:\nTO: 812023663012\nPAGE: 03\n--13\nCAN (REF)\nR80135-009 NYLON LACING AS REOD\nCUSHION\n1 RED ON -21\n3 PEO\nVERMICULITE -\nLE RBO195-002 TAPE AS REDO\nWRAP I REDD\n-TONITER (REF HYPERGOL CANISTER\nPOLYETHYLENE\nBAG I REOD\nCUSHION 3 REDO\nCAN 1 REOD\nUXE SPONTANEOUSLY COMBUSTIBLE LABEL\n1 RECO\nFLAB LIQ LBL\nRO171-1094-0001 LABEL\n¡ REDO\n-I1. -21 CAN ASSY\nEXPORT CONTROLLED PER ITAR\nPAGE 3","truncated":false,"body_characters":4982}
