Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where their temperatures will exceed 100°F/38°C and
they must never be painted, plated, coated, or otherwise
altered after leaving the factory. Modified or over-heated
sprinklers must be replaced.
Care must be exercised to avoid damage to the sprinklers
- before, during, and after installation. Sprinklers dam-
aged by dropping, striking, wrench twist/slippage, or the
like, must be replaced.
The owner is responsible for the inspection, testing, and
maintenance of their fire protection system and devices in
compliance with this document, as well as with the appli-
cable standards of the National Fire Protection Associa-
tion (e.g., NFPA 25), in addition to the standards of any
other authorities having jurisdiction. The installing contrac-
tor or sprinkler manufacturer should be contacted relative
to any questions.
It is recommended that automatic sprinkler systems be in-
spected, tested, and maintained by a qualified Inspection
Service.
