Key 2025 Developments in Fire and Life Safety Codes

The 2025 editions of key fire and life safety codes introduce several significant updates aimed at enhancing safety measures and addressing emerging technologies.

One of the notable developments in NFPA 72: National Fire Alarm and Signalling Code is the inclusion of cybersecurity enhancements. Chapter 11 now mandates specific cybersecurity measures for network-connectable equipment, requiring security levels based on interface types to safeguard fire alarm systems from cyber threats.

In addition, refined requirements ensure secure remote access to fire alarm control units, emphasising manual termination capabilities, inactivity time limits, and the presence of qualified personnel during critical activities.

Advancements in battery technology are also addressed in this code update, highlighting risks associated with higher energy densities of modern batteries and specifying the use of listed or recognized rechargeable batteries as secondary power supplies.

The inclusion of new detection technologies, such as acoustic leak detection and thermal imaging detectors, enhances capabilities for identifying gas leaks and heat sources. Furthermore, a Restricted Audible Mode Operation (RAMO) notification system has been introduced, utilising visual signals and low-frequency audible alerts in environments like early-education classrooms or facilities for individuals with noise sensitivities.

Updates to the NFPA 101: Life Safety Code include new requirements for carbon monoxide detection in certain occupancies, such as new healthcare and ambulatory healthcare facilities with fuel-fired appliances.

Another critical update mandates that all high-rise buildings be fully sprinklered by July 2028, significantly enhancing fire suppression in tall structures. Revised door-locking requirements and new guidelines for modular rooms and sleep pods address evolving safety needs in various occupancies

The NFPA 99: Health Care Facilities Code introduces requirements for auxiliary connections on medical gas and vacuum systems, enabling temporary or supplemental sources to enhance system resilience during emergencies.

New sections address the unique hazards of cryogenic liquids, providing guidelines for safe handling and system design. Terminology updates and the removal of certain references in this code aim to accommodate sustainable electrical backup power options beyond traditional generators.

These updates collectively reflect a commitment to integrating technological advancements and addressing contemporary safety challenges in fire and life safety standards. Be sure to reach out to Design Confidence if you need any further information or technical assistance.
