N
ET
system was developed for online analysis. Some mainte-
nance activities, e.g. changing the membrane caps in D.O. sensors, require the
safe handling of chemicals. Thus, we assume that the maintenance personnel
is familiar with the necessary precautions to take when dealing with chemicals
as a result of their professional training and experience.
