___________ is the response mode that responders take no direct action on the actual problem.

• A. Non-intervention
• B. Intervention
• C. Mitigation
• D. Containment

Answer: (A)

Non-intervention is the response mode where responders avoid taking direct action on the source of the problem. This approach protects responders and bystanders by establishing a safe perimeter, evacuating or isolating people, and waiting for specialized, properly equipped teams to address the hazard. It’s chosen when entering the hazard would put people at unacceptable risk or when the incident requires techniques beyond the responders’ current capabilities. The other modes involve active measures to control or reduce the hazard—direct actions to stop or manage the problem, limit its spread, or lessen its consequences—whereas non-intervention emphasizes avoiding direct contact with the hazard itself.
