What is a hazardous materials placard?

A hazardous materials placard is a sign that identifies the hazard class of the cargo being transported. These placards are essential in the transportation of hazardous materials because they inform emergency responders and others about the nature of the materials being carried. This helps to ensure safety during transport and in the case of an accident or spill. Each placard displays a specific symbol and color code that correspond to the classification of the hazardous material, such as flammable, explosive, or toxic substances. Understanding these placards is crucial for anyone involved in the transportation of hazardous materials, as they facilitate appropriate responses to potential hazards.
