Which mode involves aggressive actions to defeat the hazard?

• A. Non-intervention
• B. Defensive
• C. Offensive
• D. Containment

Answer: (C)

Offensive is the mode that centers on taking direct, active steps to stop the hazard at its source. When responders determine conditions are safe enough to intervene and they have the proper equipment, training, and command support, they move into this approach: entering the area, applying control measures right at the source, stopping the release or ignition, and working to neutralize or disable the hazard rather than just guarding or containing it. This direct action aims to reduce risk by eliminating the hazard rather than waiting for it to degrade or be isolated.

Non-intervention means avoiding entry and acting at all, defensive is about protecting people and exposures from outside the hazard without going to the source, and containment focuses on restricting the spread of the hazard rather than defeating it. Offensive actions are appropriate only when the situation permits safe direct mitigation.
