If an explosion has occurred on the fifth floor, what is the recommended action the FDNY would request the FLS Director to implement?

• A. Shelter-In-Place
• B. Lockdown
• C. Full Evacuation
• D. In-Building Relocation

Answer: (C)

When an explosion occurs on a floor, the immediate priority is to move people away from the danger and allow responders to control and assess the scene. A full evacuation accomplishes this by getting occupants out of the building and away from the blast area, reducing exposure to fire, smoke, debris, and potential secondary explosions, while enabling responders to access the hazard and account for everyone. Shelter-in-place would keep people inside, which can trap them in or near the blast zone and expose them to evolving hazards. Lockdown is a security measure focused on restricting movement, not addressing the physical danger from an explosion. In-building relocation moves people within the same building and may still place them in harm’s way or require re-entry to the hazard area. For these reasons, a full evacuation is the best course to maximize safety and enable effective emergency response.
