Inc.\nP. O. Box 1057\nMorristown, NJ 07962-1057\nDear Ms. Konrad:\nThis is in response to your letter requesting clarification of the placarding requirements under the\nHazardous Materials Regulations (HMR; 49 CFR Parts 171-180). You state that during an audit\nby the Federal Railroad Administration (FRA), disagreement arose over the correct placarding\nfor a tank car containing hydrogen fluoride, anhydrous. It is your understanding that Division\n6.1 (other than Inhalation Hazard Zone A or B) materials must be placarded POISON (see §§\n172.504(e) and 171:14(b)) and that § 172.519(b)(4) allows the use of the POISON placard in lieu\nof the POISON INHALATION HAZARD placard.\nThe current HMR requirements for placarding shipments of hydrogen fluoride, anhydrous, are\nconfusing and will be addressed in an upcoming rulemaking. A tank car containing hydrogen\nfluoride, anhydrous, must display CORROSIVE and POISON INHALATION HAZARD placards.\nYour understanding of the placarding table in § 172.504 and the transitional provisions in\n§ 171.14 is correct. Poisonous by inhalation (PIH) liquids are typically assigned to either Inhalation\nHazard Zone A or B. Hydrogen fluoride, anhydrous, a corrosive liquid which also meets the\ndefinition of a PIH material in § 171.8, is an exception in that it is assigned to Inhalation Hazard\nZone C. The subsidiary placarding requirements in § 172.505(a) require that the transport vehicle\nmust be placarded with the POISON INHALATION HAZARD placard in addition to any other\nrequired placards. It applies to PIH materials in all hazard zones. Section 172.519(b)(4) does not\napply. This latter provision addresses the display of the hazard class or division number in the\nvithout the hazard class or division number in domestic transportation by rail or highway\nower corner of a placard and the transition period that permits continued use of subsidiary placard:\nI hope this information is helpful. If you have further questions, please do not hesitate to contact\nthis office.\nSincerely,\nHotte iz. Mitchel\nHattie L.

Box 1057\nCorbin\n8171.14\nMarch 21, 2002\n$172.504\nResearch and Special Programs Administration\nOffice of Hazardous Materials Standards (DHM-10)\nUS Department of Transportation\nplacardin\n400 Seventh Street SW\n32-0086\nWashington, DC 20590-0001\nSubject:\nInterpretation on Marking and Placarding Requirements for\nAnhydrous Hydrogen Fluoride, 8, UN1052, PG 1(6.1)\nPolson Inhalation Hazard Zone C\nDear Sir or Madam:\nDuring a routine Federal Railroad Administration audit, there arose disagreement over\nthe placarding requirements of a tank car loaded with anhydrous hydrogen fluoride\n(AHF).\nHoneywell believes that tank cars of AHF are correctly marked and placarded if they\ncontain the following:\nMarks:\nProper Shipping Name - Hydrogen Fluoride, Anhydrous\nIdentification Number - 1052 (displayed on the primary hazard placard)\nAdditional Marking - Inhalation Hazard\nPlacards:\nClass 8 Primary Placard\nClass 6.1 Subsidiary Placard (not a PIH placard)\nWe believe this marking and placarding is correct, for the following reasons:\n(1)\nAccording to the placard substitution table in both 172.504 and 171.14 only\nliquids that meet the criteria or are assigned to zone A or B require the PIF\nplacard. All other class 6.1 materials, require only the poison placard.\n(2)\nEven though 172.505(a) requires that materials subject to the PIH shipping\npaper requirements (all PH zones whether primary or subsidiary, and thus AHF)\nmust be placarded with a PIH placard, 172.519(b)(4) authorizes the use of a\nregular poison placard.\nThis section states that \"stocks of non-permanently affixed subsidiary placards\nin compliance with the requirements in effect on September 30, 2001, may\ncontinue to be used in domestic transportation by rail or highway until October 1,\n2005 or until current stocks are depleted, whichever occurs first.\" On\n\n<<<PAGE 3>>>\n\nMAR-22-2002 09:48\nP.02/02\nFor these reasons, AHF tank cars, displaying both a corrosive and a poison placard,\nand showing the marks indicated on page one of this letter, would be in complete\ncompliance with the Hazardous Materials Regulations until October 1, 2005.\nI look forward to hearing your opinion on this matter. If you require any additional\ninformation, or would like to discuss this in greater detail, please do not hesitate to call\nme at the number listed below.\nVery truly yours,\nBarbara Konrad\nManager, Transportation Safety\n973-455-4009\nHoneywell International Inc.\nCc:\nPat Williams - Honeywell\nJeff Leese - Honeywell\nDerek Fletcher - Honeywell\nJim Duncan - FRA\nTOTAL P. 02","truncated":false,"body_characters":4999}
