Why Adopt?


NFPA 25 Should be on Your Code Adoption To-Do List

As you know, Illinois adopted the 2000 Edition of NFPA 101, Life Safety Code, on January 2, 2002, updating statewide requirements to reflect performance-based codes and more current NFPA standards.  This was a major public safety improvement for the state, but more remains to be done.  And because Illinois permits municipalities to develop and adopt fire safety regulations, you don’t have to wait for another statewide code adoption effort to move forward assertively.


If your jurisdiction has not yet adopted NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, that’s a good place to start.  Referenced in the Life Safety Code in Section 9, this widely used national consensus standard is adopted in 30 states, although not Illinois, and is an important component in your suite of sprinkler system requirements.  Sprinkler usage is growing in most properties and many jurisdictions prefer to establish the requirements of NFPA 25 through specific adoption, as opposed to through reference via the Life Safety Code.


The first edition of NFPA 25 was issued in 1992 and it is now in its 2015 Edition.  The standard addresses minimum requirements for the effective care of water-based fire protection systems, including sprinkler, standpipe and hose, fixed water spray, foam water, and other systems, both land-based and marine.  The inspection, testing and maintenance requirements in the standard represent the minimum necessary, allowing leeway for authorities having jurisdiction (AHJ) to require more frequent care as they see fit.


NFPA 25 outlines responsibilities of the building owner or operator, detailing specifics for care of varied systems through separate chapters, including those addressing private fire service mains, fire pumps and water storage tanks.  Additional chapters deal with Obstruction Investigation and Impairments.  Appendices to the standard include explanatory materials, forms and other useful information.



The deadly 1991 high-rise fire at the One Meridian Plaza building in Philadelphia remains a useful case study that underscores the necessity for adopting and enforcing NFPA 25, among other standards.  According to Tom Klem, who investigated the fire for NFPA, “This fire serves as a memorable example of the need for vigilance in inspection, testing and maintenance of all water-based fire protection systems.”


Extinguishment of the fire, which resulted in the deaths of three firefighters and injuries to two dozen others, was hampered by numerous failures, including inadequate water pressure in fire attack hose lines.  Klem, now a fire protection engineering consultant heading up T. J. Klem & Associates says, “Improper settings of the standpipe pressure regulating devices (PRVs) contributed to the severity of the One Meridian fire and the loss of life.  The importance of adhering to national consensus standards such as NFPA 25 is obvious, and compliance with them can prevent similar tragedies.”


If adopted and enforced in your jurisdiction, compliance with NFPA 25 will provide assurance that all the systems in your care remain well maintained and operational.


If you haven’t already educated your elected officials about this important standard, now is the time.  Bringing your jurisdiction a set of requirements to ensure routine testing of water-based fire protection systems is another step toward greater public safety for the people of Illinois, starting with your jurisdiction.
