Your questions are paraphrased and answered as follows:\nQ1.\nA truck in interstate commerce is carrying 800 pounds of \"Chlorine, 2.3, UN1017\", a\npoisonous gas with subsidiary hazard Class 8 (corrosive), in non-bulk cylinders with\nno other hazardous material on board. What placard(s) are required?\nA1.\nBoth POISON GAS and CORROSIVE placards are required, as prescribed by\n§ 172.505(a).\nQ2.\nA truck in interstate commerce carries 1,500 pounds of \"Chlorine, 2.3, UN1017,\" a\npoisonous gas with subsidiary hazard Class 8 (corrosive), in non-bulk cylinders with\nno other hazardous material on board. What placard(s) are required? Since the load\nhazard?\nexceeds 454 kg. has the placarding requirement changed because of the subsidiary\nA2.\nThe answer is the same as in A1. The fact that the load exceeds 454 kg does not alter\nthe placarding requirement.\nQ3.\nA truck in interstate commerce carries, in non-bulk packagings, 800 pounds of\n\"Bromine, 8, UN1744, PG I,\" a poisonous-by-inhalation Hazard Zone A material that\nis corrosive and has a subsidiary hazard class of Division 6.1 (poisonous material).\nWhat placards) are required?\n:\n\n<<<PAGE 2>>>\n\n..\nA3.\nBoth POISON INHALATION HAZARD and CORROSIVE placards are required, as\nprescribed by § 172.505(a).\n:\nI hope this information is helpful.

Allen\nDeputy Director\nOffice of Hazardous Materials Standards\nUS DOT/ RSPA\n400 Seventh St. S.W.\nWashington, D.C. 20590\nRe: Request for interpretation of placarding regulations.\n49 CFR 172.504 requires placarding of transport vehicles and freight containers carrying\nhazardous materials. Paragraph ( c) of that section gives the exceptions from placarding for loads\nof less than 454 kg.. Paragraph ( c) also states that the \"454 kg. exception\" does not apply to\n•bulk packagings or hazardous materials subject to section 172.505.\nMy office has received complaints of inconsistent interpretations and enforcement of the\nplacarding requirements for materials that are designated as poison inhalation hazards by the\nhazardous materials table and section 172.203(m). The complainant is a Minnesota based\ninterstate carrier of hazardous materials, who reports they have been inspected and found with no\ndefects in one state, and then crossed a state line with the same exact load and placards and have\nbeen cited for improper placarding. They have requested immediate assistance and written\nclaritication of the placarding requirements for hazardous materials with primary or subsidiary\nPIF classifications. They have provided the following examples:\n1. A truck in interstate commerce is carrying 800 pounds of \"Chlorine, 2.3, UN1017\" in\nnon-bulk cylinders. Cblorine has a Class 8 subsidiary hazard. No other hazmat is on the\ntruck. What placard(s) are required?\n2. A truck in interstate commerce carries 1500 pounds of \"Chlorine, 2.3, UN1017\" in non-\n2?1\nbulk cylinders. No other hazmat is carried. What placard(s) are required? Since the load\nexceeds 454 kg. has the placarding requirement changed because of the subsidiary hazard?\n3. A truck in interstate commerce carries 800 pounds of \"Bromine, 8, UN1744, PG I\" in\nnon-bulk packaging. Bromine has a subsidiary hazard of Division 6.1, and is designated a\nPIH material in hazard zone A by Special provision 1 on the hazardous materials table. No\nother hazmat is carried. What placard(s) are required?\nAn equal opportunity employer\n\n<<<PAGE 4>>>\n\nThe carrier reports they transport Chlorine frequently, and they will comply with all placarding\nrequirements. They intend to carry a copy of the RSPA interpretation letter in their trucks.\nThank you for your assistance in this matter.
