must be replaced.
Automatic sprinklers must never be
painted, plated, coated or otherwise
altered after leaving the factory. Modi-
fied sprinklers must be replaced.
Sprinklers that have been exposed to
corrosive products of combustion, but
have not operated, should be replaced
if they cannot be completely cleaned
by wiping the sprinkler with a cloth or
by brushing it with a soft bristle brush.
Care must be exercised to avoid dam-
age to the sprinklers - before, during,
and after installation. Sprinklers dam-
aged by dropping, striking, wrench
twist/slippage, or the like, must be re-
placed. Also, replace any sprinkler
that has a cracked bulb or that has lost
liquid from its bulb. (Ref. Installation
Section).
Frequent visual inspections are rec-
ommended to be initially performed for
corrosion resistant coated sprinklers,
after the installation has been com-
pleted, to verify the integrity of the cor-
rosion resistant coating. Thereafter,
annual inspections per NFPA 25
should suffice; however, instead of in-
specting from the floor level, a random
sampling of close -up visual inspec-
tions should be made, so as to better
determine the exact sprinkler condi-
tion and the long term integrity of the
