Dambek\nHazmat, Inc.\n12 Kimball Hill Road\nHudson, NH 0305 1-391 5\nRef. No.: 09-0201\nDear Mr. Dambek:\nThis responds to your August 14,2009 letter requesting clarification of the placarding\nrequirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 17 1-1 80).\nYour questions are paraphrased and answered below.\nQl. A shipper offers for transportation two cylinders of Chlorine, UN1017,2.3 (5.1, 8). The\ngross weight of this shipment is 800 pounds. Must the vehicle be placarded with the poison\ngas, oxidizer, and corrosive placards?\nAl. No. The required placard for \"UN 10 17, Chlorine, 2.3\" is the POISON GAS placard.\nSee 5 172.504(e), Table 1. Placarding for the subsidiary 5.1 and 8 hazards is not required, but\nis permissible as specified in 5 172.505. The HMR do not specify how to display the primary\nand subsidiary placards in relation to each other; however, each placard must be clearly\nvisible from the direction it faces.\nQ2. A shipper offers for transportation two cylinders containing residual amounts of\nChlorine, UN1017,2.3 (5.1,8). Is the shipment required to be placarded?\nA2. Yes. As specified in 9 173.29, empty packagings containing the residue of a hazardous\nmaterial must be offered and transported in the same manner as when they previously\ncontained a greater quantity of the hazardous material unless the packagings are sufficiently\ncleaned of residue and purged of vapors to remove any potential hazard, or are refilled with a\nmaterial that is not subject to the HMR.\nQ3. A shipper offers for transportation a drum of Chlorosulfonic acid, UN 1754, 8 (6. I), PG I\nfor transportation by highway. The gross weight of the material is 450 pounds. Is the\nshipment required to be placarded?\nA3. Yes. In accordance with 9 172.505(a), a poisonous material subject to the \"Poison\nInhalation Hazard\" shipping description requirements in 9 172.203(m) must be placarded with\na POISON INHALATION HAZARD or POISON GAS placard. Chlorosulfonic acid meets\n\n<<<PAGE 2>>>\n\n-2- October 1, 2009\nthe definition for a material that is poisonous by inhalation (see Special Provision 2 as\nindicated in Column 7 for the entry for Chlorosulfonic acid in the Hazardous Materials Table\nin tj 172.1 01) and, therefore, is subject to the shipping description requirements in\n172.203(m) and the placarding requirements in 5 172.505(a).\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nSincerely,\n&Hattie L.
