Bomb threats are usually received by telephone, but they may also be received by note, letter, or e-mail. All bomb threats should be taken seriously and handled as though an explosive were in the building.

What to Do When a Bomb Threat Occurs:

• If you receive a bomb threat, get as much information from the caller as possible.
• Be aware of background noise, special voice characteristic, music, machinery, etc.
• Call X5911 or 281.290.5911 immediately.
• If you receive a bomb threat, do not touch any suspicious packages.
• Clear the area around the suspicious package, and notify Police immediately.
• When evacuating a building, avoid standing in front of windows or other potentially hazardous areas.
• Do not restrict sidewalks or other areas used by emergency officials.
• If you find a bomb, do not touch it or attempt to move it. Call for help and evacuate the area.
