Which of the following is NOT a suggested action when looking for a place to hide during an active shooter incident?

In an active shooter incident, prioritizing concealment and safety is critical. Leaving lights on to signal your location runs counter to the fundamental strategies of avoiding detection and minimizing risk. The goal during an active shooter scenario is to become as invisible as possible, making it difficult for the shooter to locate individuals.

The other suggested actions—hiding behind large items, pulling curtains and shutting doors, and barricading a room with heavy items—are all meant to enhance protection and minimize exposure. These actions help create a secure environment where an individual can remain undetected until it is safe to exit or help arrives. Keeping lights on would compromise this safety by making individuals more visible, increasing the chance of confrontation with the shooter.
