Suspicious Mail

​If you decide that a letter or package is “suspicious” after comparing it to the FBI Advisory Bulletin, take the following steps:

  • Do not handle the mail piece or package suspected of contamination.
  • Isolate the person or people who have been exposed to any suspicious substance.
  • Make sure that the suspicious letter or package is isolated and the immediate area is closed off.
  • Call 911 on a college or campus phone if available. If no college/campus phone is available, use any available phone and dial 972-860-4290.

If a person suddenly experiences respiratory problems and/or blistering of the skin, place them under an emergency shower (found in science labs) and/or a regular shower (using only cold water). Turn the shower on — and leave it on — until first responders arrive.
