Understand NYC Regulatory Management for Local Laws

15.1. Obstruction Assessment


The 5-year fire sprinkler inspection is an NFPA mandated inspection examining the integrity of the fire sprinklers’ piping. The examination must be carried out a minimum of every 5 years. 

15.1.1. Scheduling

The only way to perform the test is after a Violation has been issued. Even if the Sprinkler & Standpipe Company knows that the obstruction assessment is due, one can’t be performed without the FDNY first issuing a violation. The Sprinkler Company will request a date/time from the Fire Department and the FDNY will stipulate the inspection.  

15.1.2. Inspection

The inspection will search for and be able to identify a variety of internal obstructions or problems developing within the piping, including, MIC (microbiologically influenced corrosion), Rust, Slime and other foreign organic or inorganic material. The inspection will first include an initial assessment. The initial assessment will include opening the flushing connection at one of the main ends and removing a sprinkler tower from one end of a branch line.
