Which set correctly lists the three control options at hazmat incidents?

• A. Containment, Evacuation, Public Protection
• B. Non-Intervention, Defensive, Offensive
• C. Isolation, Containment, Evacuation
• D. Prevention, Mitigation, Recovery

Answer: (B)

Three control options guide hazmat incident response: Non-Intervention, Defensive, and Offensive. Non-Intervention prioritizes life safety and stabilization with minimal action to stop the release, often by establishing exclusion zones and evacuating people while keeping responders out of the hazard. Defensive actions are taken from outside the hazard area to limit spread and protect people and the environment, aiming to confine the material and prevent exposure without entering the hot zone. Offensive operations involve entering the hazard area with appropriate PPE and equipment to directly halt the release at its source and terminate the incident, accepting greater risk to responders when necessary to prevent worse outcomes. This set is the standard because it covers progressively more direct intervention as conditions allow. Other option groupings mix tactics (like containment or evacuation) or phases (prevention, mitigation, recovery) and don’t reflect the three core control modes used in hazmat incident response.
