Which side of the hazardous materials diamond indicates instability?

Explanation:
Instability (reactivity) is shown on the yellow section of the NFPA 704 hazard diamond, which sits on the right side. Emergency responders read the right side to gauge how reactive or unstable a material is, with higher numbers meaning greater instability. The other sides indicate different hazards: the top blue is health, the left red is flammability, and the bottom white is for special hazards. So the right side is the one that communicates instability.
