What is Gowning
• Gowning: The process of wearing special
  garments in order to control particulate
  contamination.
Gowning
Importance of Gowning
 Correct gowning procedures are also of paramount
 importance. One of the problems with particulate
 contamination is that it is largely invisible to the naked
 eye. Any contamination introduced into the cleanroom
 on the outer surface of clothing will go unnoticed and
 so any breakdown in correct gowning procedures will
 not be immediately apparent. Thus it is vital that
 operators are well versed and well practiced in correct
 gowning procedures. It can be very helpful if a system
 of mutual help is in place. That is, the operators
 observe each other and, in a non-threatening way
 point out faults that may occur.
