Active Shooter/Hostage Situation
Ensure your own safety.
If you know where the intruder (or source of the security threat) is, contact Campus Security at (212) 217-7777 immediately.
Move to the nearest location that can be secured by a locked door.
If a locked door is not available, move as far away from the threat as is safely possible. Isolate yourself and restrict entry any way that is possible.
Remain quiet and do nothing to call attention to yourself.
Allow others you know and trust into your secure location.
Follow directions from New York City Police Department.
