Which step involves deciding how much response is appropriate during a critical incident?

• A. Conducting evacuations
• B. Determining the appropriate level of response
• C. Setting up perimeters
• D. Verifying the incident

Answer: (B)

The key idea here is choosing how extensive the response should be based on the situation. In a critical incident, you start by assessing the severity, risks, and resources available, then decide the appropriate level of response. That decision sets how many personnel are deployed, what kind of actions are required, and how quickly they’re carried out. Once that level is determined, you move into concrete actions like evacuations, perimeter setups, or incident verification, all of which are influenced by the chosen level.

This step is the planning decision that guides everything that follows. Evacuations are specific actions taken to move people to safety, perimeters are about containment, and verification is about confirming the incident details—each occurs after the level of response has been established.
