If there is a violent intruder or active threat to life on campus, you will receive a CornellALERT instructing you to Run, Hide, Fight. Because active threats can take multiple forms (e.g., active shooter, automobile, explosive device), it is important to always be aware of your surroundings and exercise situational awareness (e.g., where is the incident, where are the exits, what barriers are in my way). Quickly evaluate your options and commit to an appropriate action. Review the ACTIVE THREAT TO LIFE section for more information. Sign up to receive CornellALERT on your mobile device.
