Which of the following best describes a defensive response level?

A defensive response level focuses on controlling hazards while minimizing direct exposure to the threat. This approach is designed to create a barrier between personnel and the hazardous situation. The intent is to mitigate risks and protect the surrounding environment and individuals without putting responders in direct danger. For example, this may involve implementing containment strategies or managing hazardous materials from a safe distance, rather than physically engaging with the material or source of danger.

In the context of emergency response, this would mean using methods such as establishing safe zones, calling in specialized teams, or deploying equipment that allows for hazard control from a distance. This is crucial in incidents where immediate engagement could lead to additional risks for responders or the public.

In contrast, options describing an active and immediate intervention, such as rushing to contain the spill or evacuating the area without assessment, do not align with the principles of a defensive response. A defensive approach is characterized by a calculated and safety-focused response that prioritizes the well-being of emergency personnel and the public.
