In general, which response objective is the highest level of risk that is permissible for operations-level responders?

The highest level of risk that is permissible for operations-level responders is the defensive response objective. This approach focuses on containing the release of hazardous materials and preventing it from spreading to the surrounding area, thereby protecting people, property, and the environment. In a defensive operation, responders work to establish barriers or control the environment without directly engaging with the hazardous substance, minimizing their exposure to danger.

Operations-level responders are trained to identify and manage incidents involving hazardous materials, and while offensive actions may involve direct intervention, they carry a greater level of risk. The defensive stance allows responders to control the situation while prioritizing safety, effectively mitigating the hazards posed by the incident without immediate, direct action that would require a higher risk tolerance.

This strategy is also in line with established incident command practices, which encourage responders to always assess their safety first, making defensive operations the most prudent choice when balancing the need for action against the risks involved.
