In the NFPA hazard diamond, what does the number on the right side represent?

Explanation:
The number on the right side of the NFPA 704 hazard diamond is the reactivity rating. It indicates how readily the material may react under conditions like heat, pressure, shock, or contact with water or other chemicals. Ratings run from 0 to 4, where 0 means stable under normal conditions and 4 means the material can undergo a violent or explosive reaction. This helps responders decide what precautions to take and how to store or handle the material safely. The other sections measure different hazards—health (blue), flammability (red), and any special hazards (white)—but the right-side number specifically flags reactivity.
