About Five Year Obstruction Investigations

Sprinkler systems are mechanical systems that require ongoing inspections and maintenance to help keep them in optimal working condition. Over time these systems can accumulate organic or inorganic materials inside the pipe and valves. Piping, valves and other devices can even become obstructed by these materials which can cause system failure in the event of an emergency. This build-up also prematurely deteriorates and weakens the piping.

In 2002, NFPA recognized that this internal build-up compromised the integrity of the sprinkler system and posed a significant risk to life and property. Code was added to require five year internal obstruction investigations of fire protection system piping to identify sources of materials that could cause blockage and deteriorate the system. The obstructing materials can come in the form of MIC (microbiologically influenced corrosion), slime, sludge, flakey scale or even a hard packed cement like substance.
