Dear Mr. Daniell:
This is in response to your telephone conversation with a member of my staff and January 26, 2007 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to placarding and marking. Your scenario involves a transport vehicle carrying 31,500 pounds of UN 1581, Chloropicrin and methyl bromide mixtures, Division 2.3, in non-bulk packages. The transport vehicle displays a POISON GAS placard, containing the identification number "1581", on each side and each end. You ask if the transport vehicle is required to be marked with the words "INHALATION HAZARD."
The answer is no. Each non-bulk package must be marked "Inhalation Hazard" in association with the required label and shipping name as required by § 172.3 13(a). A transport vehicle containing large quantities of a material poisonous by inhalation in non-bulk packages must be marked, on each side and each end as specified in § 172.332 or § 172.336, with the identification number specified for the hazardous material. See paragraph (c) of § 172.313. The identification number may be displayed on the POISON GAS placard as permitted by § 172.3 32 and 172.334. When the identification number is displayed on the placard, there is no requirement to display the "INHALATION HAZARD" wording on the transport vehicle or across the center of an additional POISON GAS placard.
I hope this information is helpful. If you have further questions, please do not hesitate to contact this office.
