Circular Exhibit 03-01-E


A calm response to a bomb threat caller could result in the obtaining of additional information.  This is especially true if the caller wishes to avoid injuries or deaths.  If told that the building is occupied or cannot be evacuated in time, the bomber may be willing to give more specific information on the bomb's location, components, or method of detonation.

If a bomb threat is called in:

  1. Keep the caller on the line as long as possible. Ask him/her to repeat the message.  Record every word spoken by the person.
  2. If the caller does not indicate the location of the bomb or the time of possible detonation, ask him/her for this information.
  3. Inform the caller that the building is occupied and the detonation of a bomb could result in death or serious injury to many innocent people.
  4. Pay particular attention to background noises such as, motors running, music playing, and any other noise which may give a clue as to the location of the caller.
  5. Listen closely to the pitch of the voice (male, female), voice quality (calm, excited), accents, and speech patterns, phrases, and impediments.

If a written threat is received, save all materials, including any envelope or container.  Once the message is recognized as a bomb threat, further unnecessary handling should be avoided.  Every possible effort must be made to retain evidence such as fingerprints, handwriting or typewriting, paper, and postal marks.  These will prove essential in tracing the threat and identifying the writer.
