NFPA 704 Hazard Diamond with Zero Ratings and Radiation Symbol #2218549 (License: Personal Use)

The image displays a standard NFPA 704 hazard identification diamond with all three colored quadrants (red for flammability, blue for health, yellow for reactivity) marked with “0”, signifying negligible hazard. The white quadrant contains the universal black trefoil radiation symbol, indicating the material is radioactive, though it poses no significant acute danger under normal conditions. This labeling is used for substances like certain low-activity isotopes or shielded sources where physical hazards are minimal but regulatory awareness is required.

This image is commonly used in safety training, chemical database entries, and regulatory documentation to illustrate how NFPA 704 labels communicate hazard levels-including when radiation is present but other risks are absent. It serves users seeking to interpret safety signage or verify compliance with OSHA/HazCom standards.
