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\nbulk 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 carner 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\nclarification of the placarding requirements for hazardous materials with primary or subsidiary\nPI classifications. They have provided the following examples:\n1. A truck in interstate commerce is carrying 800 pounds of \"Chlorine, 2.3, UN1017\" in\n23\nnon-bulk cylinders. Chlorine has a Class & 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-\n131\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.
