No.: 07-0230\nDear Mr. Chamrnas:\nThis responds to your December 4,2007 letter requesting clarification of the placarding\nprovisions specified in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171 - 180).\nYour scenarios involve the application of $$ 172.504 and 172.505. Your questions are\nparaphrased and answered'below .\nQ 1. What placards are required on a freight trailer transporting less than 1,000 pounds of non-\nbulk packages that contain a material, UN1746, Bromine Trifluoride, 5.1 (6.1) (8), PG I,\nPoison-Inhalation Hazard Zone B?\nA1 . Under the HMR, OXIDIZER placards for the primary hazard and POISON INHALATION\nHAZARD placards are required, as prescribed by §$ 172.504(e) Table 2, and 172.505(a)\nrespectively. The 454 kg (1,OO 1 pounds) exception in $ 172.504(c) does not apply to a material\nthat is required to display a subsidiary POISON INHALATION HAZARD placard in accordance\nwith 8 172.505(a). As specified in $ 172.505(d), display of the CORROSIVE placard for the\nsubsidiary hazard is permissible, but not required.\n42. What placards are required on the freight trailer specified above in Q1 if a box of Division\n1.4G Igniters, weighing less than 5 pounds, is added?\nA2. See A1 . No additional placards are required. The Division 1.4G material is eligible for the\n$ 172.504(c) placarding exception even when transported on the same transport vehicle with\nnon-bulk packages of a Division 5.1, Poison-Inhalation Hazard material subject to $ 172.505.\nI hope this information is helpful.
