Definition of Standard Procedures 

Association of Needle-Free Injection Manufacturer's (ANFIM Page186)

During this meeting- Standard procedures are defined by Robert Harrington, maker of Ped-o-Jet, military jet injection apparatus, used by the United States Military to administer vaccines.

Quote from meeting:
    MR. HARRINGTON:  It (Ped-O-Jet) was used by the Army for 35 years and it was always wiped.  Never had an issue.  Good tracking system.  And there's nothing recorded in the world that says that it wasn't wiped.  It's in a study that was presented using a method that isn't approved, it was not wiped and it said oh, we can contaminate 31 out of 100.

"Nothing recorded in the world that says that it wasn't wiped"

....What I'm saying to you is we believe that there are situations--the U.S. military for 35 years used the product appropriately.  There was never an indicated transmission of hepatitis.  Certainly they follow cases of hepatitis in the U.S. military.      http://hcvets.com/data/transmission_methods/jet_injection_ANFIM.htm
