Emergency Response Guide

Bomb Threat

Most bomb threats are received by phone.  Bomb threats are serious until proven otherwise.  Act quickly, but remain calm and obtain information with the checklist provided in this guide.

If a bomb threat is received by phone:

  1. Remain calm.  Keep the caller on the line for as long as possible.  DO NOT HANG UP, even if the caller does.
  2. If your phone has a “Record” feature press the button to activate it.
  3. Listen carefully.  Be polite and show interest.
  4. Try to keep the caller talking to learn more information.
  5. If possible, write a note to a colleague to call the authorities or, as soon as the caller hangs up, immediately notify them yourself.
  6. If your phone has a display, copy the number and/or letters on the window display.
  7. Complete the bomb checklist immediately.  Write down as much detail as you can remember.  Try to get exact words.
  8. Immediately upon termination of the call, do not hang up, press [FLASH] on your phone and then dial *57 to activate a “trace” on the previous call.
  9. From a different phone, contact 911 and await instructions.

If a bomb threat is received by handwritten note:

  1. Call 911.
  2. Handle note as minimally as possible to preserve fingerprints, etc.

If a bomb threat is received by email:

  1. Call 911.
  2. Do not delete the message.


  • Use your cell phone; signals have the potential to detonate a bomb.
  • Evacuate the building until police arrive and evaluate the threat.
  • Activate the fire alarm.
  • Touch or move a suspicious package.
