What is the primary function of hazmat placards?

The primary function of hazmat placards is to identify the type of hazard associated with the materials being transported. These placards are essential for informing emergency responders and anyone else who may come into contact with the hazardous materials of the risks involved. They use specific colors, symbols, and numbers to clearly communicate the nature of the hazard, whether it is flammable, toxic, corrosive, or has other dangerous properties. This identification is crucial during transportation, as it helps ensure safety and preparedness in case of an accident or spill, allowing responders to take appropriate action based on the specific hazard presented.
