S.E\nWashington. DC 20590\nMr. Keith Jesse Powell\nDriver Sales Representative\nCon-way Freight\n4488 North Cornelia, Apt. 143\nFresno, CA 93722\nReference No. 11-0076\nDear Mr. Powell:\nThis is in response to your March 31, 2011 e-mail, and April 29, 2011 telephone\nconversation with a member ofmy staff requesting clarification ofthe Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180) applicable to placarding. You ask if a\ntransport vehicle, as this tenn is defined in § 171.8, loaded with one hazardous material\nthat meets the definition of two different hazard classes may use a DANGEROUS placard\nto represent its secondary hazard class.\nIn the example you provided, you state different shippers at different facilities load nonbulk\npackages of \"UN 2922, Corrosive, liquids, toxic, n.o.s. (fluorozirconic acid,\nhydrofluoric acid), 8 ( corrosive), 6.1 (poisonous), PG III\" on the same transport vehicle,\nand the total weight of the shipment is 2,205 pounds. You also state the material does not\nmeet the HMR definition for a liquid material that is poisonous by inhalation (see\n§§ 173.132 and 173 .133). You ask ifthe transport vehicle can display the Class 8 placard\nfor the primary hazard of the material and a DANGEROUS placard for its Division 6.1\nsubsidiary hazard.\nThe answer is no. The transport vehicle in your example must be placarded with the\nCORROSIVE placard. The subsidiary hazard POISON placard may also be displayed (see\n§ l72.505(d)). The HMR pennit the DANGEROUS placard to be used in place of the\nseparate placards specified for each Table 2 material listed in § l72.504(e) unless 1,000 kg\n(2,205 pounds) or more aggregate gross weight of one category ofhazardous material in\nnon-bulk packages is loaded at one loading facility. See § 172.504(b). Also, the HMR do\nnot define the tenn \"mixed load.\" For the purposes ofthe HMR, it is the opinion ofthis\nOffice that a mixed load is a shipment oftwo or more categories ofhazardous materials in\nseparate non-bulk packages that require different placards. The shipment in your example\n\n<<<PAGE 2>>>\n\nis not a mixed load because it is a \"mixture\" oftwo categories ofhazardous materials in\nthe same non-bulk package that require the same placard(s).\nI hope this satisfies your request.\nSincerely,\nr/~~\nT.
