Threat by Mail


  1. Retain all original documents (soft or hard)

  2. Prevent all original documents from further handling – touching, forwarding, and showing.

  3. Call Emergency Hotline on 777 (from IP Internal Phone)

  4. See Suspicious Packages and Objects sections of this guide.

Evacuation due to Bomb Threat

The decision to evacuate will be based on the amount of details available and whether this appears to be a legitimate threat or a prank.

If an evacuation is needed and authorized by Security:


  1. Pay attention to specific evacuation directions.
  2. Leave doors and windows open to let the blast wave escape.
  3. Take your brief case, purse, and lunch bag, etc. with you to minimize the search for the bomb.

Bomb Search

The search, if required, needs to be done visually by people who are familiar with the facility. The security and police will help, but they may not have the resources to do it alone. Employees can help by doing a quick visual search of their immediate area.


  1. Search with your eyes-only!
  2. Do not touch any suspicious object — leave removal and disposal for the Bomb Squad.
  3. Report any suspicious objects to your supervisor.
  4. Use normal phones for communication — radios or cellular phones can detonate a bomb.


The first areas to be checked should be public access areas i.e. bathroom trash cans, lobby areas, stairways, building exterior, etc.
