In which mode of operation is usually adopted when risks outweigh the expected benefits during an incident?

When the risks associated with a fire incident or emergency response situation outweigh the expected benefits of taking action, a defensive mode of operation is typically adopted. This approach prioritizes the safety of personnel and the protection of resources rather than aggressive action.

In a defensive operation, firefighters may focus on confining the incident, protecting exposures, and ensuring that they do not put themselves in harm's way without a substantial chance of success. It recognizes the reality that certain situations pose significant hazards, and thus, a more cautious strategy is warranted. This might involve establishing a perimeter, using aerial devices for water application, or employing other tactics that minimize risk while still addressing the incident's critical aspects.

Other operational modes, such as offensive, supportive, and proactive, suggest a more aggressive engagement with the incident, which would not be appropriate when the inherent risks are deemed too great. The defensive approach allows for a measured response aligned with the overall safety of the team and the community, ensuring that actions taken are justifiable and focused on mitigating risk.
