Emergency Procedures

Active Shooter


If a hostile intruder/active shooter is OUTSIDE your building:


  • Get to a room that can be locked; close and lock doors and windows
  • Turn off the lights
  • Get everyone down on the floor so no one is visible from outside of the room
  • Call 911 and answer the dispatcher's questions
  • Stay in place; calls from unfamiliar voices may be the attacker attempting to lure you out
  • Do not respond to any voice commands until you are sure that they are from a Police Office or a Campus Safety Officer


If a hostile intruder/active shooter is INSIDE your building:


  • If it is safe to do so, exit the building immediately
  • Notify anyone you may encounter that they should exit the building immediately but do not let anyone's indecision slow you down
  • Call 911 and answer the dispatcher's questions
  • If exiting the building is not possible, take the following actions:
  • Go to the nearest room or office
  • If you are locked out of all rooms, seek refuge in the nearest restroom, lock yourself in a stall, stand on the toilet, and keep calm
  • Close and lock the door and/or block it with furniture
  • Cover any windows
  • Call 911 and answer the dispatchers questions; if you cannot speak, keep the line open
  • Keep quiet and act as if no one is in the room; silence all cell phones
  • DO NOT answer the door
  • Stay in place
  • Do not respond to any voice commands until you are sure they are from a Police Officer or Campus Safety Officer


If a hostile intruder/active shooter ENTERS your office or classroom:


  • Remain calm
  • Dial 911; if you cannot speak keep the line open
  • Try to escape if you are able
  • If escape is impossible, you must take action to survive!
    • Try to hide
    • Play dead
    • Attempt to overpower the attacker with force; use anything at your disposal and fight for your life
    • If someone other than yourself acts to overpower the attacker it is recommended that you assist; the more people involved will increase the success of overpowering the attacker
If a hostile intruder/active shooter LEAVES your area:
  • Close and lock the door and/or block it with furniture
  • Call 911 if you have not already done so
  • DO NOT answer the door
  • Do not respond to voice commands until you are sure that they are from a Police Officer or Campus Safety Officer
If you decide to flee during a hostile intruder/active shooter situation:

  • Do not attempt to carry anything while fleeing
  • Do not attempt to remove injured people
  • Move quickly
  • Keep your hands up; high and visible
  • Follow the instruction of any Police Officers or Campus Safety Officers you encounter
What to expect from responding police officers:
  • Police Officers responding to an active shooter situation proceed immediately to the area in which shots were last hears. Their purpose is to stop the shooting as quickly as possible. The first officers to arrive will not stop to aid injured people; rescue teams composed of other officers and emergency medical personnel will follow after areas have been secured.
  • Understand that the police will be treating all those they encounter as possible suspects. When you encounter the police:
    • Remain calm
    • Do as the officers tell you
    • Put down and bags or packages you may be carrying
    • Keep your hands up and visible at all times
    • If you know where the hostile intruder/active shooter is, tell the officers
    • Once out of harm's way, remain at whatever assembly point authorities designate
    • Do not leave until you have been interviewed and released

Shelter in Place (Weather)
Shelter in place is the safety term used to notify the community of a weather related emergency – typically a tornado or severe storm including hail. The University of Denver’s shelter in place procedures are as follows:
  • Stop classes or other operations in the building
  • If there are visitors in the building, provide for their safety by asking them to stay--not leave. When public safety officials provide directions to shelter in place, they want everyone to take those steps immediately, where they are
  • Tornado sirens are intended to notify those outdoors to make their way inside
  • Once inside, make your way to a room or area without exterior glass
  • Remain calm and await further instructions, once the threat has passed, Campus Safety will send the notification
    • If out in the open:
      • Do not wait out the storm in your car, attempt to outrun the tornado by driving perpendicular to its path
      • Move away from the path of the tornado
      • Seek shelter in a sturdy building
      • If no buildings are available, lie face down in the nearest depression, ditch, ravine, or culvert; cover your head with your hands and stay there until the storm has passed
Shelter in Place (Hazardous Materials)
In some instances, it may be safer to “shelter in place” (i.e. remain indoors) in order to avoid the release of hazardous materials. In this case, it may be necessary to shelter in place following the intentional or accidental release of a chemical, biological, or biological contaminants into the environment. The University of Denver’s shelter in place procedures are as follows:
  • Close and lock all doors leading into your office area
  • Alert others in your office of the order
  • Close all exterior windows
  • Gather all personnel into a central location. Choose a room with none or few windows or vents
  • Do not use the telephone for non-essential purposes (such as contacting the media)
  • Do not investigate unusual or suspicious noises outside your office area
  • Remain until the “all clear” alert is given
Utility Failure
These may include electrical outages, plumbing failure/flooding, gas leaks, ventilation problems, elevator failures, etc.
For your personal safety, in the event of a utility failure:
  • Remain calm
