When a threat is outside the building, you may need to seek shelter. Go into the closest building if you are outside and stay there until the order is lifted.
During severe weather, you should seek shelter on the lowest floors in interior rooms, hallways, or staircases (without windows).
During an active assailant situation, take action: run, hide, fight. If you are unable to run, you should hide. Seek shelter in the nearest lockable room. If the door does not lock, use heavy items to barricade the door. Stay away from windows. Silence phones and stay quiet. Consider items you could use to defend yourself against an attacker, if needed. Stay in your locked/barricaded location until officials say it is safe to leave.
