An Instructive Photo:  The Internet and news are filled with photos of people doing it wrong. Here we see someone doing it right:
N-95 mask fitting the face closely;
Safety glasses (goggles that seal at the edges are preferred) protecting the eyes;
Cap keeping hair clean;
Long sleeved gown that can be discarded;
Latex gloves (or comparable if she is allergic to latex).
I assume her shoes are covered as well.

After the procedure, she will remove garments, mask, goggles carefully and discard in a plastic bag. 

Where working with the obviously infected and in some conditions, even more facial covering is used.  (FYI: My own source for supplies is www.LabSafely.com)

Do not forget that Flu virus is airborne and can live outside the body for a couple of weeks.  It can be caught from surfaces (use disinfectant)  or from contaminated air.  All mucous membranes must protected.  This means goggles for eyes.  Latex exam gloves are excellent protection: they should be removed with out touching the outside.  They act as a psychological barrier to  keep you from putting your hands in your mouth, eyes  and nose.  Coveralls may also be needed when one knows one is exposed. 
    Disposal of used equipment without touching the infected surface is a must.  No hanging your mask from one ear, wearing it on mouth but not nose, etc. 
Masks should not be re-worn and should be disposed of without touching the outside. Hand washing follows equipment removal.

     Hand washing in all circumstances at frequent intervals and at after touching surfaces is a good idea. Covering mouth and nose when coughing or sneezing, followed by disposal of the tissue is a must.  Do not cough or sneeze into your bare hand.  It is better to sneeze into the inside of your elbow.  Why?  You are apt to touch door knobs, pens,, other items with your hands.
