The Research and Special Programs Administration (RSPA) has issued a final rule that amends the hazardous materials regulations (49 CFR Parts 171, 172, and 173) regarding placarding and labeling, according to information in the Federal Register November 4. The revisions include allowing the use of the Pantone Formula (an industry guide for colors) for hazard warning labels and placards; and expanding the use of labels specified in the Compressed Gas Association Pamphlet C-7 on cylinders used to transport Division 2.1, 2.2, or 2.3 gases to all modes of transportation.

The revisions also include requiring a non-odorized marking on certain cylinders, portable tanks, cargo tanks, and tank cars and multi-unit tank car tanks containing unodorized liquefied petroleum gas; and allowing a fumigant marking to be removed from a transport vehicle or freight container before the lading is unloaded, if the vehicle has undergone sufficient aeration.

RSPA said the revisions will enhance hazard communication for the safe handling of hazardous materials in transportation and the prompt identification of hazardous materials involved in transportation incidents.
