<br />Initial and frequent visual inspections of
<br />random samples are recommended for
<br />corrosion -resistant sprinklers to verify
<br />the integrity of the corrosion -resistant
<br />material of construction. Thereafter,
<br />annual inspections per NFPA 25 should
<br />suffice.
<br />Inspections of corrosion -resistant
<br />sprinklers are recommended at close
<br />range, instead of from the floor level
<br />per NFPA. Inspection at close range
<br />can better determine the exact sprin-
<br />kler condition and the long-term integ-
<br />rity of the corrosion -resistant material,
<br />which can be affected by the corrosive
<br />conditions present.

<br />Responsibility lies with the owner for
<br />the inspection, testing, and mainte-
<br />nance of their fire protection system
<br />and devices in compliance with this
<br />document, as well as with the appli-
<br />cable standards of the National Fire
<br />Protection Association (for example,
<br />NFPA 25), in addition to the standards
<br />of any other authorities having jurisdic-
<br />tion. Contact the installing contractor or
<br />sprinkler manufacturer regarding any
<br />questions.
<br />Automatic sprinkler systems are rec-
<br />ommended to be inspected, tested,
<br />and maintained by a qualified Inspec-
<br />tion Service in accordance with local
<br />requirements and/or national codes.
<br />Care must be exercised to avoid dam-
<br />age to the sprinklers -before, during,
<br />and after installation. Sprinklers dam-
<br />aged by dropping, striking, wrench
<br />twist/slippage, or the like, must be
<br />replaced. Also, replace any sprinkler
<br />that has a cracked bulb orthat has lost
<br />liquid from its bulb. (Ref. Installation
<br />Section).
<br />Initial and frequent visual inspections of
<br />random samples are recommended for
<br />corrosion -resistant sprinklers to verify
<br />the integrity of the corrosion -resistant
<br />material of construction. Thereafter,
<br />annual inspections per NFPA 25 should
<br />suffice.
