OSHA issues Protective Guidelines for Biological Threats.

(OSHA Compliance Advisor, BLR, Nov.12, 2001)

Recommendations stress that mail should be opened carefully, with a minimum amount of movement, and using a letter opener or method that is least likely to disturb the contents. The guidelines recommend that employees:

• Not blow into envelopes
  
  
• Not shake or pour out contents
  
  
• Keep hands away from nose and mouth while opening mail
  
  
• Always wash hands after handling mail.
