The building notification for an active shooter incident is highly recommended to:

• A. Indicate that there is an active shooter incident
• B. Inform occupants where the shooter was last seen
• C. Indicate that there is an active shooter incident and, if possible, inform the occupants where the shooter was last seen
• D. Notify emergency services only

Answer: (C)

In this kind of situation, the most effective notification tells people immediately that there is an active shooter and, if possible, provides the last known location of the shooter. This combination gives clear, time‑sensitive information that lets occupants make quick, practical decisions about what to do next—evacuate along safe routes away from the last seen location or shelter in place when escape isn’t feasible. Merely signaling that an incident is happening can leave people unsure where to go or what to expect, while sharing only the last-known location without confirming an active threat can create ambiguity. Relying on emergency services alone delays guidance that people on the ground need to respond effectively in the moment. So, the most effective approach is to indicate the incident and, if possible, inform occupants where the shooter was last seen.
