(1) Chances are very small of receiving a warning call that a bomb
has actually been placed. We cannot ignore telephone warnings because there
have been cases where a threatening call was not a hoax.
(2) The person making such a call could reveal enough information
about himself so that he might later be identified. There have been cases
where a caller has not only described the bombing device, he has given its
location, and stated the time it was to go off.
b. Actions to Take When Warning Call is Received (See Appendix A). It

is this calling, please?" "What is your name?" In some cases, the caller
may unthinkingly reply.
c. After the Threatening Call. After the threat has been received, the

This may be your supervisor, the Bomb Scene Officer, Staff Duty Officer, or

a. Analyze the bomb threat immediately after it is received, to avoid
dangerous delay and indecision.
Person(s) must be predesignated to
determine the following:
(1) How will the threat be evaluated?
(2) Who will evaluate the threat?
b. Evaluate the bomb threat, and take proper action by:
