What are the three keys to surviving an active shooter situation?

Avoid the threat. If possible, leave the area as soon as possible and get as far away from the shooter, preferably outside and away.

Deny the shooter access to you if you can’t get away. If you cannot exit the area safely, do not “hide and hope.” Actively find a location where you can keep the attacker away from you. Ideally, pick a location that offers both cover (stops a bullet from hitting you) and concealment (hides you from the shooter). Lock the door if possible, and use anything you can to barricade it such as tables, desks, chairs, or other heavy objects.

Defend yourself. In some situations, you’ll have no choice but to fight back against an active shooter. If your only option is to defend yourself, look around your area for “improvised” weapons. Choose items within reach that can be used to injure or disable the active shooter like a fire extinguisher, shovel, scissors, coffee mug, or even a pot of hot coffee.
