Suspicious Packages

Be wary of suspicious packages and letters. They can contain explosives, chemical or biological agents. Be particularly cautious at your place of employment. Some typical characteristics postal inspectors have detected over the years, which ought to trigger suspicion, include parcels that:

• Are unexpected or from someone unfamiliar to you.
• Have no return address, or have one that can't be verified as legitimate.
• Are marked with restrictive endorsements, such as "Personal," "Confidential" or "Do not x-ray."
• Have protruding wires or aluminum foil, strange odors or stains.
• Show a city or state in the postmark that doesn't match the return address.
• Are of unusual weight, given their size, or are lopsided or oddly shaped.
• Are marked with any threatening language.
• Have inappropriate or unusual labeling.
• Have excessive postage or excessive packaging material such as masking tape and string.
• Have misspellings of common words.
• Are addressed to someone no longer with your organization or are otherwise outdated.
• Have incorrect titles or title without a name.
• Are not addressed to a specific person.
• Have handwritten or poorly typed addresses.

With suspicious envelopes and packages other than those that might contain explosives, take these additional steps against possible biological and chemical agents.

• Refrain from eating or drinking in a designated mail handling area.
• Place suspicious envelopes or packages in a plastic bag or some other type of container to prevent leakage of contents. Never sniff or smell suspect mail.
• If you do not have a container, then cover the envelope or package with anything available (e.g., clothing, paper, trash can, etc.) and do not remove the cover.
• Leave the room and close the door, or section off the area to prevent others from entering.
• Wash your hands with soap and water to prevent spreading any powder to your face.
• If you are at work, report the incident to your building security official or an available supervisor, who should notify police and other authorities without delay.
• List all people who were in the room or area when this suspicious letter or package was recognized. Give a copy of this list to both the local public health authorities and law enforcement officials for follow-up investigations and advice.
• If you are at home, report the incident to local police.

In the immediate area of a terrorist event, leave quickly and orderly. Listen to police, fire, and other officials for instructions. Leave the building as quickly as possible. Do not stop to retrieve personal possessions or make phone calls. If things are falling around you, get under a sturdy table or desk until they stop falling. Then leave quickly, watching for weakened floors and stairs and falling debris as you exit.
