Following up on Bob's post. NFPA 13, the 2025 edition is now open for public input. My staff has been very active in reviewing the 2022 edition of NFPA 13 and other documents which are open for inputs.
If any member needs assistance on submitting or developing public inputs, please contact our staff at [email protected]. *The above is my opinion and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects. This is provided with the understanding that the AFSA assumes no liability for this opinion or actions taken on it and they are not to be considered the official position of the **AFSA, and/or NFPA or its technical committees.**AFSA cannot provide design or consulting engineering services, and this opinion should therefore not be considered, nor relied upon, as such.* Thanks, John John August Denhardt, PE *Vice President, Engineering and Technical Services* *American Fire Sprinkler Association* m: p: 301-343-1457 214-349-5965 ext 121 w: firesprinkler.org <https://www.facebook.com/firesprinkler.org/> <https://twitter.com/afsa/status/1039528345367732224> <https://www.linkedin.com/company/american-fire-sprinkler-association-afsa-/> <https://www.instagram.com/firesprinklerorg/> *Our members are at the heart of everything we do.* Expand your design department in 2022!
