What type of hazard does a yellow placard typically indicate?

A yellow placard typically indicates the presence of radioactive materials. This color-coding aligns with the National Fire Protection Association (NFPA) and the Department of Transportation (DOT) regulations, which use specific colors to signify the nature of the hazards associated with the materials.

The yellow placard is designated for radioactive materials, indicating that these substances can emit radiation, which poses health risks to those who are exposed without proper protective measures. Understanding this classification is crucial for personnel involved in handling or responding to incidents involving hazardous materials, ensuring safe practices and appropriate emergency responses are employed.

In order to manage the risks associated with hazardous materials effectively, it is essential to be familiar with the color-coded system of placards as they provide immediate visual cues about the nature of potential dangers present.
