brushing it with a soft bristle brush.

nozzles installed in potentially corro-
sive atmospheres to verify the integ-
rity of the materials of construction
and finish as they may be affected by
the corrosive conditions present for a
given installation. Thereafter, annual
inspections per applicable standards
are required, in addition to inspec-
tions required by the authority having
jurisdiction.
