This session highlights key updates in the 2025 edition of NFPA 13, including new listing requirements for fire protection air compressors and the adoption of Vapor Corrosion Inhibitor (VCI) technology, which now allows a Hazen-Williams C-Factor of 120 for new systems. Additionally, we’ll review the 2024 NFPA 14 requirement mandating supervisory air for all dry standpipe systems. Attendees will gain a comprehensive understanding of how these updates impact design, installation, and compliance for fire protection air supplies.

Upon completion of this seminar, attendees will be able to:

• Identify and interpret critical updates in the 2025 NFPA 13, including new listing requirements for fire protection air compressors and the adoption of Vapor Corrosion Inhibitor (VCI) technology.
• Examine the implications of the Hazen-Williams C-Factor allowance for VCI-treated systems and the 2024 NFPA 14 requirement for supervisory air on all dry standpipe systems, ensuring proper compliance.
• Recognize how these updates impact system design, installation, and maintenance to optimize the performance and longevity of fire protection systems.
