For sprinkler systems to be effective for fire control and extinguishment, internal piping and sprinkler heads must be free from obstructions, such as scale,silt and other foreign organic and/or inorganic material.
NFPA research shows that sprinklers were effective 96% of the time when they operated. In the other 4% of the cases, ineffectiveness was related to water not reaching the fire 42% of the time and lack of maintenance 3% of the time. Although the author has not found any NFPA statistics that directly track the effectiveness of sprinklers because of obstructions, it has been recognized as a potential problem that is now addressed in NFPA 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems.
