GOWNING

Chittaranjan DasSr. Production Officer

GowningWhat is Gowning• Gowning: The process of wearing

special garments in order to control particulate contamination.

GowningImportance 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.
