Part D: DISCUSS EVALUATION AND EVACUATION CONSIDERATIONS
Evaluation of the bomb threat is carried out by the bomb scene officer. He considers the results of the
bomb threat checklist, information from support agencies, and the mission of the targeted facility. With
this in mind, he must decide which of the three following actions to take.
o Business as usual.
o Search without evacuation.
2. Business as Usual. After evaluating all the evidence at hand, the bomb scene officer may feel that
the credibility of the caller is questionable. He may decide to go about business as usual. This might
be the case if the caller is recognizable from previous hoaxes. The bomb scene officer will still report
the message to other authorities. This action should be taken only when the likelihood of hoax is
extremely great and there will be interruption of operations if any search is made.
3. Search Without Evacuation. A hoax may be suspected, but it is not obvious. The bomb scene
officer can elect to conduct a search without evacuation. This search may be overt or covert depending
on the facility and the likelihood of interrupting operations.
4. Evacuation. If the bomb threat was a descriptive one, the possibility of an actual bomb being
present is greatly increased. In this case, evacuation is called for. The bomb scene officer should
consider that personnel evacuation might expose them to greater danger. Also, the bomb scene officer
must consider the time the bomb is set to go off, if the caller reveals this information.
The following is a list of considerations involved in evaluating a bomb threat:
o An evaluation of the person making the threat, his apparent motivation and demeanor.
o When and where the bomb will go off.
o Type of structure and how prone it is to damage.
o Identification of a recurring threat.
o Call caused by news reports of other calls.
o Whether employees are excused from work when such threats are received.
