The DOT requires marking, labeling, and placarding of hazardous materials being transported in commerce to, from, or within the U.S. The term "placarding" refers to the placement of large durable versions of hazard labels on transport vehicles, bulk packages, freight containers, unit load devices, and rail cars. The purpose of marking, labeling, and placarding is to communicate the potential dangers of hazardous materials. Placards are especially important to emergency responders, who use this information to initiate protective actions after an incident or accidental release.
