What does the NFPA label's white color indicate?

The NFPA label's white color specifically indicates radioactivity. The National Fire Protection Association (NFPA) established this color-coded labeling system to convey vital information regarding the hazards associated with various materials. Each color within the label serves a unique purpose, with white being designated for materials that present a radiation hazard.

Understanding the significance of the NFPA color code is crucial for ensuring safety in environments where hazardous materials are managed. In the context of the other options, flammable hazards are typically marked with red, health hazards with blue, and general hazardous materials might not have a specific color on the NFPA label. Thus, recognizing that white corresponds to radioactivity helps individuals identify and take appropriate precautions when dealing with materials that pose radiation risks.
