The packaging used to secure hazardous materials during transport typically contains markings and labels to indicate that it contains a hazardous material. The purpose of these markings and labels is to communicate the hazards and risks of the materials being transported to anyone who could be exposed to them. All markings must be legible and durable; clearly visible; written in English; printed on or affixed to the package surface or a label, tag, or sign; and placed away from other markings (such as advertising) that could substantially reduce their effectiveness. DOT marking requirements are detailed in Part 172, Subpart D of the HMR.
