Your questions are paraphrased and answered as follows:\nQ1.\nYour company receives rail cars from Canada containing \"Chlorine\" classed as a Division 2.3\n(Poison gas). The Canadian rail car displays the international \"TOXIC GAS\" placard with the\nidentification number \"UN 1017\"displayed across the middle, and the United States'\n\"POISON GAS\" placard is displayed containing the words \"INHALATION HAZARD.\"\nYou asked, should the United States' \"POISON GAS\" placard display the identification\nnumber \"UN 1017\" instead of the text \"INHALATION HAZARD\" on the placard.\nAl.\nA Canadian rail car containing Chlorine transported to the United States from Canada must be\nplacarded with the POISON GAS placard specified in § 172.504(e), Table 1, and as shown in\n§ 172.540. Except for a RADIOACTIVE or DANGEROUS placard, text indicating a hazard,\nsuch as \"INHALATION HAZARD\", is not required on a placard (see § 172.519(b)(3)). The\nrail car must be marked \"Inhalation Hazard\" on two opposing sides of a bulk packaging as\nspecified in § 172.313(a). When the words \"INHALATION HAZARD\" appear on the\nplacard, the marking is not required on the package.\nThe identification number \"UN 1017\" must be marked on each side and each end of a rail car\nas prescribed in §172.330. In accordance with § 172.332, an identification number may be\ndisplayed on a placard, orange panel, or white square-on-point configuration.
