What is the purpose of a hazardous materials placard?

The purpose of a hazardous materials placard is to identify the hazard class of the cargo being transported. These placards serve as a critical visual warning to others about the nature of the hazardous materials, ensuring that anyone who comes into contact with the vehicle or its cargo is aware of the potential dangers. Each placard has a specific color and symbol that represents a particular class of hazardous materials, such as flammable liquids, toxic substances, or corrosive materials.

This identification is crucial in emergency situations, allowing first responders to understand the risks they may face when dealing with an incident involving that vehicle. It also helps in ensuring proper handling and safety measures are followed during transportation, loading, and unloading of the hazardous materials.
