Dear Ms. Camara:
This responds to your January 27, 2014 request for clarification of the use of the DANGEROUS placard under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if §§ 172.500(b)(6) and 172.502(c) permit the display of a DANGEROUS placard on a transport vehicle containing two or more categories of non-bulk when one of those commodities is a combustible liquid in a non-bulk package.
In accordance with § 172.504(b), a freight container, unit load device, transport vehicle, or rail car which contains non-bulk packages with two or more categories of hazardous materials that require different placards specified in table 2 of § 172.504(e) may be placarded with a DANGEROUS placard instead of the separate placarding specified for each of the materials. Section 172.500(b)(6) states that “placarding does not apply to combustible liquids in non-bulk packaging.” However, § 172.502(c) states “placards may be displayed for a hazardous material, even when not required, if the placarding otherwise conforms to the requirements of this subpart.” It is your understanding that displaying a DANGEROUS placard on a transport vehicle containing Table 2 Class 3 flammable liquid and Table 2 combustible liquid (both in non-bulk packages) is permissible under the HMR.
Your understanding is correct. A COMBUSTIBLE placard is not required for combustible liquids in non-bulk packaging (§ 172.500 (b)(6)). However, a placard may be displayed for a hazardous material, even when not required, provided the placarding is carried out in conformance with Part 172, Subpart F. Therefore the use of the DANGEROUS placard on a transport vehicle containing Class 3 flammable liquid and combustible liquids, both in non-bulk packages, is authorized under the Part 172, Subpart F provided all other requirements of
§ 172.504(b) are met.
I hope this answers your inquiry. If you need additional assistance, please contact this office on (202) 366-8553.
Sincerely,
Robert Benedict
