What color placard indicates a radioactive hazard?

The correct answer is white, as the white placard is used specifically to indicate radioactive hazards in accordance with established safety protocols and standards. In hazardous materials communication, color coding plays a critical role in quickly conveying the type of risk present. The white placard typically features a symbol that signifies radiation, alerting responders and personnel to the presence of radioactive materials and the potential dangers associated with them.

The use of a distinct color like white ensures that individuals can readily identify and differentiate between various types of hazards, facilitating appropriate safety measures and responses. As part of emergency response protocols, recognizing these color codes is essential for maintaining safety and ensuring proper handling of hazardous materials, especially in situations involving radioactive substances.
