Dear TSgt. Rubalcaba
This is in response to your letter requesting clarification of the placarding requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the exception from placarding in § 172.504(c), for less than 454 kg (1001 pounds) aggregate gross weight of hazardous materials covered by Table 2 of 172.504(e), applies to the Division 2.2 material in cylinders. You indicate that the cylinders are loaded on a single transport vehicle and weigh approximately 4,800 pounds.
The placarding exception in § 172.504(c) applies to the aggregate gross weight of all non- bulk packagings on a single transport vehicle that are covered by Table 2 of
§ 172.504(e) and do not fall under the provisions of 172.505. As defined in § 171.8,
the phrase "gross weight" is the weight of a packaging plus the weight of its contents.
In your scenario, the aggregate gross weight is equivalent to the aggregate weight of all cylinders and the Division 2.2 material they contain. Therefore, given that the aggregate gross weight of your cylinders is approximately 4,800 pounds, the transport vehicle must be placarded.
I hope this information is helpful. Please contact us if you require additional assistance.
Sincerely,
John A. Gale
