Workplace Preparedness


Employee response to a bomb threat is mainly that of data collection to provide to law enforcement agencies. Once a bomb threat is reported, law enforcement officers will take control of the situation. University Administration, following the advice of law enforcement agencies, will determine if evacuation is necessary.


  • Remain calm. If possible, transfer the call to UC Police Department's Communication Center at (310) 825-1491.
  • Keep the caller on the line as long as possible; be courteous and do not interrupt the caller. Take all bomb threats seriously.
  • If possible, signal a co-worker to indicate that you have received a bomb threat.
  • Complete a Bomb Threat Form or write down as much information as possible to provide to Security. Try to note:
    • Caller's gender, age, unique speech attributes.
    • Indications about where the device is, when it is set to go off, what it looks like, and why it was placed.
    • NOTE: If a threat was delivered, describe the messenger, direction of travel and any suspicious persons in the area.
  • Call 9-1-1 immediately from a hard-wired telephone once the call has been completed if no one else has called to report the threat; follow EMERGENCY EVACUATION procedures as directed by emergency response personnel. Follow evacuation instructions precisely as you may be instructed to evacuate to an alternate site.
  • Notify your supervisor and the Facility Warden as soon as possible.

Precautions and Guidance

  • Do not search for a device or touch suspicious devices.
  • Call 9-1-1 from a hard-wired telephone - do not use cell phones or a radio to report a bomb threat as cell phones and radio signals could trigger detonation of the bomb.
