Lewis\nFlight Simulation Branch\nAviation Division (FL TSIMBR, A VN DIV)\nDefense Ammunition Center\n187 Markwell Street, Building 1292\nHunter Army Airfield\nFort Stewart, GA 31409-5503\nReference No. 10-0015\nDear Ms. Lewis:\nThis is in response to your letter and subsequent telephone conversation with a member of my\nstaff requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171180)\napplicable to hazardous materials communication. Specifically, you ask how to determine\nif a material is a poisonous-by-inhalation or toxic-by-inhalation hazard when the proper shipping\nname and other information that accompany it do not include the words \"poison,\" \"toxic,\"\n\"poison-inhalation hazard (PIH),\" or \"toxic-inhalation hazard,\" herein described as PIH. In your\nletter, you state your military shipping facility receives hazardous materials from a variety of\nmanufacturers that sometimes do not include their product's hazard classification information.\nYou also state your facility often has no time to retrieve this information before it must prepare\nthese materials for rapid deployment overseas. Your questions have been paraphrased and\nanswered in the order you provided.\nQl. If! put the POISON INHALATION HAZARD warning label (see § 172.429) on a\npackage that contains \"UN 1052, Hydrogen fluoride, anhydrous, 8 (corrosive), 6.1\n(poison), Packing Group (PG) I,\" do I have to communicate this hazard on the shipping\npaper? The entry for this material on the Hazardous Materials Table (HMT; § 172.101)\nincludes Special Provision 3 in Column 7. This provision states hydrogen fluoride\nanhydrous meets the criteria for a PIH Hazard Zone C, but does not refer to § 173.133,\nwhich prescribes how to assign the PG and hazard zone for a Division 6.1 material. Note\n2 under the § 173.133(a)(2)(i) table states only liquid PG I, Hazard Zone A and B\nmaterials meeting the criteria prescribed in § 173.133(a)(2) are subject to additional\nshipping paper (§ 172.203(m», marking (§ 172.313), and placarding (§ 1 72.504(e), Table\n1) requirements for PIH materials.\nA1. The answer is yes. \"UN 1052, Hydrogen fluoride, anhydrous\" is a Class 8, Division 6.1\nliquid that meets the definition of a Zone C \"material poisonous by inhalation\" in\n§ 171.8. Although § 172.203(m) does not require that the Zone C liquid material\npoisonous-by-inhalation hazard be communicated on a shipping paper, § 172.402(a)(2)\nrequires that a PG I, Division 6.1 subsidiary hazard label be displayed on the package. In\n\n<<<PAGE 2>>>\n\naddition, § 172.202(a)(3) requires that the subsidiary hazard be entered on a shipping\npaper when a subsidiary hazard label is required (also see §§ 172.400(b), 172.429(a), and\n172.442(a». Please note the words \"Inhalation Hazard\" are not required to be marked on\nthe package ifthey appear on the hazard label (see § 172.313(a». The motor vehicle,\nrailcar, aircraft unit load device, or other transport vehicle the material is transported on is\nalso required to display the POISON INHALATION HAZARD placard because the\nmaterial is subject to the shipping description requirements for a poisonous-by-inhalation\nhazard (see § 172.505(a».\nQ2. The hazardous materials listed here all have Special Provision 5 in Column 7 oftheir\nrespective entries on the § 172.101 Table, which tells me if these materials meet the\ndefinition of a PIH material, I must select a proper shipping name that identifies them as\nsuch.\nNo. UNINA# Proper Shipping Name Hazard\nCJass(es)\nPacking\nGroup\nSpecial\nProvisionl\nHazard\nZone\n1.

The concern is how do\nI determine which item is a PIH if this information is not shown on the HMT and not\nprovided by the shipper and/or manufactiJrer, and what if anything has to be annotated on\nthe document? Again, § 173 .133( a)(2)(i), Note 2, states only those items in Zones A and\nB must be annotated in accordance with § 172.203(m).\n2\n\n<<<PAGE 3>>>\n\nA2. Under § 173.22, it is the shipper's responsibility to properly classify a hazardous material\nbefore it is offered for or transported in commerce. As stated in Answer AI, the shipper\nis also responsible for stating the PIH hazard on the shipping paper, label, and placard\nthat accompany the material. If the words \"Inhalation Hazard\" do not appear on the label\nor placard, they must appear on the package marking (see § 172.313(a». Packages of\nPIH materials that do not include this information are in violation of the HMR and must\nnot be offered for transportation in commerce. You can obtain classification information\nabout a hazardous material from the product manufacturer or its material safety data sheet\nfor the product, or by using methods prescribed in the HMR that include product testing\nor the use of reliable data or documented experience (see §§ 173.132 and 173.133 for\nDivision 6.1 liquids). Also, § 173.133, Note 2, states that Division 6.1, PG I, Zone A\nand B liquids must be annotated in conformance with § 172.203(m)(2), marked in\nconformance with § 172.313, and placarded in conformance with Table 1 of\n§ I 72.504(e), but does not exclude other PIH materials from having to comply with these\nrequirements.\nQ3. These hazardous materials entries have Special Provision 6 in Column 7 ofthe HMT.\nThis means they are PIH materials and must include this in their hazard communication.\nAgain, a POISON GAS label can be applied to the item. The concern is what if any\nrequirement is there for the shipping paper under § 172.203(m). That is, how do I\ndetermine which zone to communicate?\nNo. UNINA# Proper Shipping Name Hazard\nClass(es)\nPossible\nHazard\nZone\nSpecial\nProvisionl\nHazard\nZone\n1.

The overall concern is documentation requirements\nThe first item is PSN: Hydrogen fluoride anhydrous nUN 1052. This item is a Hazard Class 8 (6.1) with a\nspecial provision of 3. However lAW 172.102, Special provisions the number 3 does not refer you back\nto 173.133. The concern is if I put the toxic inhalation hazard label on the package, do I have to\ncommunicate this on the document. lAW Note 2 in 173.133 is specifically states that only 6.1 that\nmeets the criteria of Zone A or B has to be communicated on the document lAW 172.203 m.\nThese next items all have special provision of 5, which tells me if the material meets the definition of an\ninhalation hazard to select a PSN that identifies it as such. Attaching the label to the package can easily\nbe accomplished, the concern how do I determine which item to select and what if anything has to be\nannotated on the document. Again, 173.133 says only those items in Zones A and B must be annotated\nlAW 172.203m.\nUN 1583 Chloropicrin mixtures n.os. 6.1\nNA 1911 Diborane mixtures 2.1\nUN 2983 Ethylene Oxide and propylene oxide mixtures, 3 (6.1)\nUN 1614 Hydrogen cyanide, stabilized 6.1\nUN 2478 Isocyanates, flammable, toxic n.o.s 3 (6.1)\nUN 2285 Isocyanatobenzotrifluorides 6.1(3)\nUN 3281 Metal carbonyls, liquid n.o.s 6.1\nUN 3275 Nitriles, toxic, flammable n.o.s 6.1 (3)\nUN3276 Nitriles, toxic liquid n.o.S 6.1\nUN 3280 Organoarsenic compound, liquid n.o.s 6.1\nUN 3279 Organophosphorus compound, toxic, flammable n.o.s 6.1(3)\nUN 3278 Organophosphorus compound, toxic, liquid n.o.s 6.1\nUN 1828 Sulfur chlorides, 8\n\n<<<PAGE 5>>>\n\nThese last items have a special provision of 6, which says they are inhalation hazards and must be\ncommunicated as such.
