Research and Washington, D.C. 20590 pecial Program dministratio FEB 2 2 2002 Mr. Dana Probasco R+L Carriers Haz-Mat Specialist, Safety Dept. Ref. No. 02-0043 P.O. Box 271 Wilmington, OH 45177-0271 Dear Mr. Probasco: This responds to your February 6, 2002 letter concerning placarding requirements in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). You ask how to placard a transport vehicle containing a Class 8 (corrosive), UN 1780, material in a bulk container weighing 1,500 pounds and a Class 3 (flammable liquid), UN 1993, material in a non-bulk package weighing 500 Ibs. Specifically, you asked if the weights of the two materials are added together to determine placarding requirements. The answer is no. Section 172.504(c) provides a placarding exception exclusively for non-bulk packages containing Table 2 materials, as defined in § 172.504(e), in a transport vehicle or reight container. If the aggregate gross weight of the non-bulk packages and their contents i ess than 454 kilograms (1,001 pounds), a placard is not required for these materials. However § 172.504(a) requires the transport vehicle or freight container to be placarded if it contains a bulk packaging of a Table 2 material. Therefore, the correct placard for your packaging scenario is "CORROSIVE." Although § 172.502 permits the use of a "FLAMMABLE" placard in addition to the "CORROSIVE" placard, it is not required. I hope this satisfies your request. Sincerely, Transportation Regulations Speciali Office of Hazardous Materials Standards 172.504 020043 <<>> FEB BS 2002 11:17 FR R~L CARRIERS SAFETY, 937 382 2677 TO 12023563012 P.01/01 «RIL CARRIERS» Transter, Inc.

Example: A Class 8 UN1760 Table 2 Haz-Mat item in a Bulk container (15001bs.) and a Class 3 UN1993 Table 2 Haz-Mat item in a Non bulk container (500 lbs.) arc placed in the same transport vehicle. What will the Placards be? We believe that the Table 2 materials in the Bulk vs. the Non-bulk are treated separately and the weights are not to be combined. Are we correct in our assessment? I have spoken to your department on two different occasions regarding this but we would like a letter of interpretation for our records.
