Types Of Bombs

Letter and Package Bombs:

Letter or package bombs represent an excellent delivery method if the motive of the attack is to inflict injury upon a specific individual. Employees should be very alert for:

Warning - Examine all Mail Gently!

Balance: Letters and packages will feel unbalanced, the contents may shift and or make sloshing sounds. Letters may feel rigid, appear uneven or lopsided and are bulkier than normal.

Sweating: Some chemicals used in explosives may "sweat" and result in "greasy" marks on wrappings.

Odors: Some of these chemicals may also give off unusual odors, which the human nose will quickly sense. For example, the Oklahoma City bomb was constructed of nitrogen based commercial fertilizer. The next time you use garden or lawn fertilizer, note the smell. Nitrogen explosive devices may emit the same odor. These orders can be similar to almonds or marzipan.

Feel: Letters have a normal "feel." Those that contain devices may simply not "feel" right, or they may be "stiff." This can indicate the presence of plastic or metallic components as opposed to the normal paper stuffing.

Packaging: Be very cautious of envelopes or packages, which are found within other packages. This may be an attempt to mask or hide the actual explosive device. Wrapping exhibits previous use such as traces of glue, mailing labels, return addresses, or tape. The package may be secured with several different types of tape and may have an excessive amount of postage stamps.

Addressing: Be cautious of items marked "To Be Opened Only By," "Personal," "Private," or one which carries a strange place of origin, script, disguised or unusual writing or type, obvious misspelling or altering of words in the address field, or the lack of a return address.

Foreign Packages: If the item is from another country, ask yourself if it's expected. Do you have relatives or friends traveling? Did you purchase something from an international organization.

Place of Origin: Is the postmark a familiar one.

Un-requested Deliveries: Is correspondence from the sender expected? Does the characteristics of the envelope or package resemble the expected contents? Does the addressee normally receive personal mail at work.

Writing: Any mail that features a foreign style of writing, not normally received at your address should be treated with caution.

Protruding Wires: Any wires, tinfoil, or strings protruding from a package or letter should be treated with caution.

Sounds: If there's any unusual sounds coming from a package such as a buzzing or ticking noise, use extra caution.

If a package exhibits any of these warning signs contact the TUHSC Police immediately at 988-5555.
