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 damage to the sprinklers before, during, and after installation. Sprin- klers damaged by dropping, striking, wrench twist/slippage,or the like,must be replaced. Also, replace any sprin- kler that has a cracked bulb or that has lost liquid from its bulb (Ref. Installa- tion section). 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 applicable standards of the National Fire Protection Associa- tion (e.g., NFPA 25), in addition to the standards of any authorities having jurisdiction.Contact the installing con- tractor or product manufacturer with any questions. Automatic sprinkler systems are rec- ommended to be inspected, tested, and maintained by a qualified Inspec- tion Service in accordance with local requirements and/or national codes.
