What type of hazard does a placard with a flame icon represent?

A placard featuring a flame icon signifies a flammable hazard. This symbol is employed to denote materials that can easily ignite and burn readily, posing significant fire risks during transportation. The presence of the flame icon alerts handlers and emergency responders to the potential danger of fire associated with the material being transported.

In the context of hazardous materials, understanding placards is crucial for ensuring safety on the roads and preventing accidents. Flammable materials can include liquids, gases, or solids that can catch fire easily. The clear identification through such a placard helps in taking the necessary precautions and handling procedures to mitigate any risks involved.
