Any campus telephone can access emergency services by dialing 911.

Emergency telephone call boxes are located at almost every street intersection and other strategic locations on the Purdue Campus. The "ETS" (Emergency Telephone System) boxes are painted yellow, have a blue light on top, and are marked "Emergency."

To use the Emergency Telephone System, open the door and push the button. In a matter of a few seconds, Purdue Police Headquarters will answer. Please speak clearly and slowly into the box.
