In the NFPA (National Fire Protection Association) system, a placard featuring a "3" specifically indicates a high hazard in terms of flammability. This rating system uses a numerical scale from 0 to 4, with each number representing the level of danger associated with a chemical or material.

A "3" means that the material can be ignited under most ambient temperatures, suggesting it requires special precautions when handled or stored due to the potential for flashback or explosion. This classification underscores the need for awareness and readiness to deal with flammable materials, as they pose significant risks in both transportation and emergency response situations.

Understanding these ratings is crucial for first responders and others in hazardous materials management, as it helps guide their actions in mitigating risks associated with flammable substances.
