In the event of an explosion, downed aircraft (crash) on campus or similar incident, take the following action:

  1. Immediately take cover under a desk, table or other object that will protect you from falling objects and flying debris.
  2. After the initial explosion, call x5555 (Voice/Videophone), x5444 (TTY),  use the DPS pager address:, or call 911 to report the incident only if your area is unaffected by the explosion at that time.
  3. Evacuate the building IMMEDIATELY. Do not use elevators.
  4. Do not move seriously injured people, unless they are in immediate danger (fire, building collapse, etc.) and the risks to you appear minimal.
  5. Stay clear of the affected building. Keep streets and walkways clear for emergency response vehicles.
  6. Do not return to the building or attempt to search for other people.
  7. All people should go to the Primary Emergency Site or the Secondary Evacuation Site if the Primary Evacuation Site is the building affected.
  8. If you are trapped in a falling building:
    • Use a flashlight.
    • Stay in your area so you don't kick up dust.
    • Cover your mouth with a handkerchief or cloth.
    • Tap on a pipe or wall so that rescuers can hear where you are.
    • Use a whistle if you have one.
    • Only shout if cannot make noise another way. (Shouting can cause you to inhale dangerous amounts of dust.)
