Campus Safety may initiate an emergency lock down of one or more buildings when there is an imminent threat to the PLU community. Occupants may also initiate a lock down to protect themselves from perceived threat.
Campus Safety will remotely activate networked key card access locks on entrance doors. Occupants in some buildings can activate the key card locks on entrance doors by using the lock down pull station. In buildings without key card locks, designated occupants will lock the entrance doors during normal business hours. Know the lock down system and limitations in your building.

Learn what to do when unable to avoid threat.
Close sources of fresh air, such as windows, fireplace dampers, and ventilation systems, when possible, and do not use the elevator. Do NOT move in and out of building. If the threat is severe, relocate within the building to an upper floor away from exterior doors and windows. Select a room(s) which is easy to seal and, if possible, has a water supply and access to restrooms. If you smell gas or vapor, hold a wet cloth loosely over your nose and mouth and breathe through it in as normal a fashion as possible.
If available, take a radio or television to the selected shelter room to track emergency status. Keep telephone lines free for emergency responders. For instance, do NOT call 911 to find out what is going on. Maintain secure position until notified by recognized emergency responders that it is safe to move.
