Active Shooter

An active shooter is an individual actively engaged in killing or attempting to kill people in a confined and populated area. In most cases, there is no pattern or method to their selection of victims. An active shooter incident is unpredictable and can evolve quickly. It is often over within 10-15 minutes.

If you hear, or think you hear gunshots react quickly.

This Active Shooter video demonstrates the actions one should take if involved in an active shooter situation. (Closed captioning available)


This PowerPoint presentation details the three phases of training, so you can feel more prepared for an active shooter situation.

Definitions of Run, Hide, Fight:

Run. If there is an escape path, get out.

  • Evacuate whether others agree to follow.

  • Leave belongings behind.

  • Help others escape, if possible.

  • Run in a zig-zag pattern instead of a straight line
  • Take cover behind poles, trees, and cars (preferably behind the engine block)
  • Prevent others from entering the area.

  • Call 911 when safe to do so.

Provide law enforcement or the 911 operator with the following information:

  • Location of the active shooter

  • Number of shooters

  • Physical description of shooter/s

  • Number and type of weapons held by the shooter/s

  • Number of potential victims at the location

Hide. If evacuation is not possible, hide out. If you are in an office, stay there and secure the door. If you are in a hallway, get into a room and secure the door. Your hiding place should:

  • Be out of the shooter's view

  • Provide protection if shots are fired in your direction

  • Not trap you or restrict your options for movement

Once in a hiding place, keep out the shooter.

  • Lock the door.

  • Blockade the door.

  • Silence your cell phone and electronic devices.

  • Turn off any source of noise (radios, TV).

  • Hide behind large items.

  • If there are two or more of you, spread out. Do not huddle together. Quietly develop a plan in the event the shooter enters.

  • Remain quiet. Remain calm.

  • Dial 911 if able (if you can't speak, leave line open).

  • When you feel it's safe, do everything you can to escape.

Fight. As a last resort, take out the shooter.

  • Act with physical aggression.

  • Throw items and improvise weapons.

  • Yell.

  • Commit to your actions.

How to react to law enforcement:

The first responders on the scene are not there to evacuate or tend to the injured. They are there to stop the shooter.

  • Remain calm, and follow officers' instructions.

  • Put down any items in your hands.

  • Immediately raise hands and spread fingers.

  • Keep hands visible at all times.

  • Avoid making quick movements towards officers.

  • Avoid pointing, screaming and/or yelling.

  • Do not stop to ask officers for help, just proceed in the direction from which officers are entering the premises.

Indicators of Potential Violence:

Individuals typically do not just "snap", but display indicators of potentially violent behavior over time. If these behaviors are recognized, they can often be treated. Potentially violent behaviors by an individual may include one or more of the following (this list is not comprehensive, nor is it intended as a mechanism for diagnosing violent tendencies):

  • Increased use of alcohol or drugs

  • Unexplained increase in absenteeism; vague physical complaints

  • Noticeable decrease in attention to appearance and hygiene

  • Depression/ withdrawal

  • Resistance and overreaction to change in policy and procedures

  • Repeated violations of University policies

  • Increased severe mood swings

  • Noticeably unstable emotional responses

  • Explosive outbursts of anger or rage without provocation

  • Suicidal comments

  • Behavior which is suspect of paranoia

  • Increasingly talks of problems at home

  • Escalation of domestic problems in the workplace; severe financial problems

  • Talk of previous incidents of violence

  • Empathy with individuals committing violence

  • Increase in unsolicited comments about firearms and other dangerous weapons or violent crimes
