No.: 11-0197\nDear Mr. DiGirolamo:\nThis responds to your August 15,2011 email seeking clarification ofthe placarding requirements\nofthe Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically you ask\nwhat markings and placards are required for certain shipments ofmaterials that are poisonous by\ninhalation that are loaded at one facility and prepared in accordance with the International\nMaritime Dangerous Goods (IMDG) Code and DOT SP-7835. You provided two examples of\ncommon shipments, which I have paraphrased in the following two scenarios:\nScenario 1:\nWhat are the marking and placarding requirements for a motor vehicle containing 3,000 pounds\nof a Division 2.3, PIH Hazard Zone A material with a subsidiary Division 2.1 hazard; 8,000\npounds of a Division 6.1, PIH Hazard Zone B material with a subsidiary Class 8 hazard; and 500 '\npounds of a Class 8 material with a subsidiary Class 6.1, PIH Hazard Zone B hazard? You\nindicated that under the IMDG Code, the Class 8 material does not have a subsidiary hazard.\nScenario 2:\nWhat are the marking and placarding requirements for a motor vehicle containing 1,000 pounds\nofa Division 2.3, PIH Hazard Zone A material with a subsidiary Division 2.1 hazard; 3,000\npounds ofa Division 6.1, PIH Hazard Zone B material with a subsidiary Class 8 hazard; and 500\npounds ofa Class 8 material with a subsidiary Class 6.1, PIH Hazard Zone B hazard? You\nindicated that under the IMDG Code, the Class 8 material does not have a subsidiary hazard.\nSection 171.23(b)( 1 O)(iv)(A) specifies the marking, labeling, and placarding requirements for\nmaterials poisonous by inhalation transported in accordance with the IMDG Code in a closed\ntransport vehicle or freight container. The section states that a label or placard conforming to the\nIMDG Code specifications for a \"Class 2.3\" or \"Class 6.1\" label or placard may be substituted\nfor the POISON GAS or POISON INHALATION HAZARD label or placard, as appropriate. It\nfurther states that a freight container must be marked with the ID number, regardless ofthe total\n\n<<>>\n\nquantity in the freight container, as specified in § 172.313( c) and placarded as required by\nsubpart F of part 172 ofthe HMR.\nWith respect to placarding in both scenarios, the transport vehicle or freight container must be\nplacarded with the POISON GAS, FLAMABLE GAS, POISON INHALATION HAZARD and\nCORROSIVE placards in accordance with subpart F ofpart 172. However, a \"Class 2.3\" or\n\"Class 6.1\" placard may be substituted for the POISON GAS or POISON INHALATION\nHAZARD placard, as appropriate. Also, for domestic transportation, it should be noted, in\naccordance with §172.504(f)(8), a POISON INHALATION HAZARD placard is not required on\na transport vehicle or freight container that is already placarded with a POISON GAS placard.\nWith respect to marking for non-bulk packagings, § 171.23(b )(1 O)(iv)(A) requires that the\ntransport vehicle or freight container in both scenarios must be marked on each side and each end\nas stated in § 172.332 or § 172.336, with the identification number specified for the hazardous\nmaterial in the § 172.1 0 1 table for all three hazardous materials in the shipment, despite the\nprovisions and limitations stated in § 172.3 13(c).\nI hope this answers your inquiry. If you need additional assistance, please contact the Standards\nand Rulemaking Division at (202) 366-8553.\nBen Supko\nActing Chief, Standards Development\nStandards and Rulemaking Division\n\n<<>>\n\nDrakeford, Carolyn (PHMSA)\nFrom: INFOCNTR (PHMSA)\nSent: Wednesday, August 17, 2011 4:23 PM\nTo: Drakeford, Carolyn (PHMSA)\nSubject: FW: Hazmat Information Center Feedback: General Information, Regulations, and Definitions\n(Sections 171.1 – 171.26)\nHi Carolyn}\nMs. Sandler requested the following e-mail be submitted as a formal letter of interpretation\nin her 8/17/11 phone call with the Info Center.\nThanks,\nVictoria\n-----Original Message----From:\nPHMSA-Feedback [mailto:PHMSA-Feedback]\nSent: Monday, August 1S} 2e11 3:22 PM\nTo: PHMSA HM InfoCenter; PHMSA Webmaster\nSubject: Hazmat Information Center Feedback: General Information, Regulations, and\nDefinitions (Sections 171.1 – 171.26)\nTo whom it may concern.\nRE: 49CFR 171.23 & 172.313\nAir Products and Chemicals} Inc ships several combinations of PIH substances. It is common\nfor us to ship similar loads via road domestically and also as a preliminary road leg for an\nocean shipment. Our practice is to prepare ocean shipments in accordance with the IMDG code\nas outlined in 49CFR part 171 subpart C. We have encountered numerous occasions where there\nis confusion and disagreement over the marking and placarding requirements of the transport\nvehicle or freight container.\nOur shipments may include a combination of PIH gases and liquids. Domestic shipments of\nthese combinations are transported under the terms and conditions of DOT SP-783S. These\nconsignments would be loaded at one facility and shipped in closed freight containers.\nTwo examples of common shipments are outlined below.\nLoad A\n• 3}eee lbs Division 2.3 (2.1) PIH Hazard Zone A / One UN number\n• 8}eee lbs Division 6.1 (8) PIH Hazard Zone B / One UN number\n• see lbs Class 8 (6.1) PIH Hazard Zone B / One UN number\nɨe7; Note: Material 3 has no subrisk per IMDG\nLoad B\n• 1eee lbs Division 2.3 (2.1) PIH Hazard Zone A / Two UN numbers\no One UN number 8ee lbs} the other 2ee lbs\n• 3eee lbs Division 6.1 (8) PIH Hazard Zone B / Two UN numbers\no One UN number 2eee lbs, the other 1eee lbs\n• see lbs Class 8 (6.1) PIH Hazard Zone B / One UN number\nɨe7; Note: Material 3 has no subrisk per IMDG\nWe respectfully request PHMSA's input and guidance on the minimum marking and placarding\nrequirements for each of these scenarios, both domestic road and preliminary road for ocean\nshipment.\nMost Sincerely\n1\n\n<<>>\n\nAir Products &Chemicals Inc.\nName: Hope Sandler\nOrganization: Air Products & Chemicals Inc\nEmail: Sandleh@airproducts.com\nAddress: 7201 Hamilton Blvd\nCity: Allentown\nZip Code: 18195\nPhone: 610 481 7713\n2","truncated":false,"body_characters":6322}
