IF YOU ARE SUSPICIOUS OF A MAILING AND ARE UNABLE TO VERIFY THE CONTENTS WITH THE ADDRESSEE OR SENDER: DO NOT OPEN.

  • Isolate the mailing and evacuate the immediate area.
  • Do not put it in water or a confined space such as a desk drawer or filing cabinet.
  • If possible, open windows in the immediate area to assist in venting potential explosive gases.
  • If you have any reason to believe a letter or package is suspicious, do not take a chance or worry about possible embarrassment if the item turns out to be innocent-instead, contact Public Safety at 911 in Newark, 831-2222 in Wilmington and 645-4333 in Southern Delaware for professional assistance.
