This blog provides valuable insights into the evolving landscape of NFPA 25, the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. For fire protection professionals, staying informed about these updates is critical to maintaining compliance, ensuring safety, and optimizing business practices. Here’s a summarized breakdown:

Key Takeaways on NFPA Code Development and Updates

1. The NFPA Process:

• Anyone can participate in the NFPA’s code development process by submitting input through their online platform.
• Changes proceed through multiple stages: public input, committee review, and final approval at the NFPA Conference.
• Symbols in the standards (e.g., shaded Δ for deletions, bold italic N for new material) help users identify modifications.

1. State and Local Adoption:

• Jurisdictions may take years to adopt the latest editions, but professionals should stay informed to prepare for impending changes.

Highlights of NFPA 25 Updates

NFPA 25 2020 Edition:

• New Definitions:
  • Automated Inspection and Testing and Lowest Permissible Suction Pressure.
• Inspection Requirements:
  • Relocation of owner responsibilities (e.g., recalled components) to enforceable sections.
  • Dry hydrant ITM requirements (not dry barrel).
• System Performance:
  • Failure to provide system demand for fire pumps is now an impairment.
• Revised Chapters:
  • Extensive updates to Chapters 12 and 13, including new timing requirements for waterflow alarms.

NFPA 25 2023 Edition:

• Testing Updates:
  • Nitrogen system maintenance requirements.
  • New testing intervals (e.g., fast-response sprinklers extended to 25 years).
• Clarifications and Additions:
  • Labels for pressure-reducing valves.
  • Inspection of head guards and painted sprinkler heads.
• System Adjustments:
  • Chapter 14 changes for obstruction investigations (e.g., dry/preaction systems with a 25% delay threshold).
  • Consolidation of waterflow alarm device testing into Chapter 13.

NFPA 25 2026 Proposed Changes:

• Annual internal inspections for all dry, preaction, and deluge valves.
• Requirements for solenoid monitoring device testing and sprinkler inventory in spare head cabinets.
• New definitions and rules:
  • Horizontal standpipes, abandoned systems, and escutcheon plates.
  • FDC piping inspection exemptions for shorter sections (≤10 feet).
• Proposals include requiring 50-year replacement for standard response sprinklers in dwelling units.

Importance for Fire Protection Professionals

• Compliance and Safety: Understanding these updates ensures systems are maintained to current standards.
• Operational Impact: Modifications like nitrogen testing or solenoid monitoring may necessitate new equipment or procedures.
• Proactivity: Even if newer editions aren’t enforced yet, knowing upcoming changes enables better planning and resource allocation.
