4109 - Handling Bomb Threats


This policy and procedure applies to Layton City employees, in the absence of departmental policies.  This policy is not intended to override police or fire department standard operating procedures.


While some threats may turn out to be false, employees must treat each one as if it is entirely true.  Every effort should be made to react calmly and avoid panic.  The typical bomber wants to disrupt normal activity and produce panic.  The City desires to make every attempt to mitigate the situation before it escalates to chaos.

Handling Telephoned Threats

The phone call is the most important element in threat management as it is the only opportunity to actually speak with the caller. An employee receiving such a call should:

  • Be calm and courteous;
  • Listen carefully, take notes if needed, do not interrupt the caller;
  • Ask questions:
    • When will it go off? Hour? Time Left
    • What kind of bomb is it?
    • Where are you now?
    • How do you know so much about the bomb?
    • What is your name? Address?
  • Notify the Police Department and Administration as soon as caller hangs up;
  • Complete bomb threat fact sheet as soon as possible;
  • Be discrete with other employees to avoid hysteria.

Handling Written Threats

A written threat should be handled by as few people as possible to safeguard it for forensic processing.  The employee finding the threat should notify a supervisor, the Police Department and Administration as soon as possible.  Above all, the recipient must be discrete to avoid hysteria.

Initiating a Search

A search may be initiated under the direction of the Police Department. Usually employees should search their own workplaces, since they are most familiar with what does or doesn't belong in a particular area. Usually the search should work from outside to inside the building. Searchers are only looking for suspicious objects.  Under no condition should anyone move or touch the object.  Professionals in explosive ordnance disposal will determine what is or isn't a bomb.  The probability of finding a bomb that looks like the stereotypical one is almost non-existent, so employees should be prepared for anything.

In some cases, bombs are sent by letter or parcel.  Some of the telltale signs of a suspect package bomb are:

  • No return address;
  • Excessive postage;
  • Misspellings of common words;
  • Lumpy or rigid envelopes that are stiffer or heavier than normal;
  • Oily stains or protruding wires or aluminum foil.
