Suspicious Package Indicators and Recommended Response Procedures

Package bombs, which include letters, parcels, and anything delivered by postal or courier service, are not a new technique and have been used by terrorists and anarchist groups. Many of these bombs are triggered when victims handle or open the packages, although they can be initiated in other ways.

Package bombs come in a variety of shapes and sizes, and they may look harmless. There are a number of characteristics that may lead you to become suspicious of a letter or package.

If you believe a letter or package is suspicious:

• Stop. Do not handle or open.

  

• Do not use cell phones, pagers, or two-way radios near suspected devices.
• Be aware of secondary devices.
• Evacuate and isolate the immediate area.
• If applicable, activate the facility’s emergency plan.
• Make note of the characteristics that caused suspicion.
• Call 911.

Formal Screening Procedures
Commercial or government entities with mail screening procedures are advised to review existing procedures for screening packages, identifying suspicious items, and instituting the appropriate safety protocols.

If no current procedures are in place, guidance should be sought from local, state, and/or federal resources. Planning considerations should include (but not be limited to) recurring training for screeners, an understanding of the standards and limitations for operating times, and regularly scheduled maintenance of screening equipment, such as calibration, updates, and testing.

Response Procedures
The NETF prepared this document to raise awareness of package bombs and the need for diligence and safety procedures in evaluating suspected improvised explosive devices. If a suspicious package is found, call 911.  Any diagnostic or render safe actions should be performed only by the appropriate experts.
