What is a Placard?

A placard is a sign used to identify hazardous materials during transportation. These signs are crucial for the safe movement of dangerous goods, as they provide important visual information to responders, transporters, and the public about the nature of the materials being transported. Placards display specific symbols, colors, and numbers that correspond to various classes of hazardous materials, allowing individuals to quickly assess the potential risks associated with the shipment.

This system of labeling helps ensure safety by facilitating proper precautions, emergency responses, and compliance with regulatory requirements. The use of placards is mandated by regulations to ensure that all stakeholders involved in the transportation of hazardous materials are informed and can respond appropriately to emergencies, thereby preventing accidents and promoting safety in the transportation process.
