Which color diamond identifies hazard reactivity and explosive potential?

• A. Red
• B. Yellow
• C. Blue
• D. White

Answer: (B)

Reactivity and explosive potential are shown by the yellow section of the NFPA 704 hazard diamond. In this labeling system, blue covers health hazards, red covers flammability, yellow covers reactivity (which includes the likelihood of violent chemical changes or explosive reactions), and white lists special hazards. The numbers in each colored section (0–4) indicate how severe that hazard is. So, the yellow area is the color that signals reactivity and explosive potential. The other colors don’t indicate this specific risk.
