GREEN ZONE: Workplaces Where Contamination with Anthrax Spores Is Unlikely

---

This zone covers the vast majority of workplaces in the United States. Since October 2001, anthrax spores have only been discovered in a very limited number of workplaces.

PRUDENT WORK PRACTICES

Establish procedures for safe handling of mail and packages. Employees should:

• Be on the lookout for suspicious envelopes or packages.
• NOT open suspicious mail!
• Open mail with a letter opener or another method that minimizes skin contact with the mail and is least likely to disturb contents.
• Open mail with a minimum amount of movement.
• Not blow into envelopes.
• Keep hands away from nose and mouth while opening mail.
• Turn off fans, portable heaters, and other equipment that may create air currents while opening mail.
• Wash hands after handling mail.
