National Fire Protection Association Requirements for the 5 Year Obstruction Inspection Service

Jan 17th, 2017 - 5:45am

Help protect life and property with code-required inspection of your automatic sprinkler inspection, including the 5 year obstruction inspection service and the FDC backflush.

An automatic fire sprinkler system has components that can age or wear out over time. Valves, piping and other devices can become obstructed by materials or corrode to the point where they might leak or fail under pressure. That can put lives and property at risk.

The NFPA started the inspection code requirements for automatic fire sprinkler systems in 2002. This move is helping to drive proper maintenance of these critical life safety systems. The NFPA requires that an internal inspection of the pipe be conducted every 5 years. This type of inspection can identify Microbiologically Influenced Corrosion (MIC), rust and slime that may obstruct the piping and compromise the system.

An investigation of piping and branch line conditions must be done every 5 years. This is done by opening a flushing connection at the end of one main and by removing a sprinkler toward the end of one branch line to investigate for presence of foreign organic and inorganic material.

AFP offers this 5 year obstruction inspection service in order to keep your system ready and in good working order in case of an emergency. If our inspections identify any obstructions or corrosion we will take samples and have them tested by an independent lab. At the end of that process, we can make recommendations for appropriate corrective actions.

Another NFPA 5 year recommendation is the flushing of your FDC (Fire Department Connection) on your property. This process is necessary in order to ensure that, in case of an emergency, the fire department can hook into the FDC and it is free of obstructive material that may not allow water to pass. You would be surprised by the amount of sediment or other foreign materials that can build up in your FDC connection! Again, NFPA stared the inspection code requirement so that any obstruction of the FDC be flushed out as to not compromise this life-saving Fire Department Connection.

You can trust that our sprinkler professionals at AFP Systems, Inc. can perform these services in various types of water-based fire sprinklers, including wet, dry, pre-action and ESFR (early suppression fast response systems). Our reporting provides a valuable historic record of inspection that can be used for insurance purposes and liability claims, and can reduce your insurance rates.
