PHMSA has released the DOT Chart 17 - Hazardous Materials Markings, Labeling and Placarding Guide to assist shippers, carriers, and other stakeholders to quickly access information regarding hazardous materials markings, labels and placards.
Note: the DOT Chart-17 has been updated to remove the ORM-D marking and transitional phase-out dates for other marks, labels, and placards. The Chart has also been updated with editorial changes for clarity and to reflect the most current HMR citations and notes.
