1.9.4 Carefully inspect the test plate:
1.9.4.1 Without taking the lid off the test plate, assure that impingement marks are present on
the agar surface. This should look like a grid pattern of impingement marks that
matches that of the 300 hole inlet cover (Fig A)
Fig A
1.9.4.2 If impingement marks are not present, the sample/test may be considered invalid.
NOTE:
Although not overly common, due to excessive moisture of a test plate, impingement
marks, may be “erased” from the agar surface. Ensure that plates with excessive
moisture are not used to avoid this situation.
1.9.5 Assure all applicable information is recorded on the test plate, as required. Upon completion
of the test period, a printout (label or Paper) may be generated from the optional thermal printer
with the sample parameter information (e.g., Sample Start/Stop Time, Flow Rate, Volume, Site
Description, Date, User ID, Sample Run ID, etc.). The paper can be retained or the label can
be affixed to the bottom of the agar plate or required paperwork. The operator may initial and
date the printout if desired.
1.10
If additional samples are to be taken at the same location during the same test period (e.g., for
continuous process monitoring), repeat Steps 1.5 through 1.8.5 for each additional sample required.
1.11
If additional samples are to be taken at different locations in the same area on the same day, move the
RAS to the next location and repeat applicable portions of this procedure. If the unit is to be used in
a different area on the same day (i.e., moved from one classified area to another) it is suggested to
repeat applicable sanitization procedures in the next area prior to monitoring.
