Each situation will be different and will require you to make judgments and decisions based on the information immediately at hand. First and foremost, faculty, staff, and students must be continually vigilant to the risk of violence on campus and embrace threat assessment. Most attackers engage in some behavior prior to the incident that causes others concern or indicated a need for help. Don't be reluctant to alert Public Safety or someone else in authority if you have concerns about a member of the campus community.

• Be vigilant for “clues” as most school attackers will conduct extensive reconnaissance of their target; they will analyze the availability of ingress and egress points.
• If a shooting begins or you are close to an emergency situation, immediately call 911 or dial 7-5555 on any WMU campus phone or (269) 387-5555 from a cell phone. Report the location and any injuries to the police dispatcher. It maybe practical to leave the phone line open so the dispatcher can monitor the situation.
• If the shooter is in the classroom or office: everyone should attempt to get to a safe place or some type of cover and lie down as flat as possible away from windows or the field of fire. Obstructions between the person and the shooter can be used for concealment; keeping in mind the obstruction may not be bulletproof. If you reach a safe place, stay down on the floor and do not move. Do not raise your head to peek. Wait and listen for directions from the police.
• If the shooter is not in the classroom or office: everyone should stay inside the classroom or office, move behind any available cover and stay on the floor. Close and lock the door if possible, turn off the lights, and close any window blinds. Do not peek outside of the classroom or office and report the location of the shooter if known to the police dispatcher. Everyone should stay in the room until a police representative advises it is clear and safe to leave.
