NFPA recently released the 2025 edition of NFPA 110, Standard for Emergency and Standby Power Systems. This new version has essential updates for maintaining and testing Emergency Power Supply Systems (EPSS). This blog post will discuss Chapter 8, “Routine Maintenance and Operational Testing.”
NFPA 110 Chapter 8 Overview
NFPA 110, Chapter 8, is about “Routine Maintenance and Operational Testing.” It explains the steps to keep the Emergency Power Supply System (EPSS) reliable and ready. This chapter is significant for facility managers tasked with updating systems to comply with safety standards and regulations.
Routine Maintenance and Operational Testing (NFPA 110, 8.1)
NFPA 110, 2025 edition, states that maintenance and testing programs should adhere to manufacturer recommendations, instruction manuals, Chapter 8 requirements, and authority directives. The maintenance and testing program should follow the manufacturer’s recommendations.
It should also follow instruction manuals and Chapter 8 requirements. Additionally, the program should adhere to authority directives. Together, these elements form a comprehensive approach to maintaining the integrity and functionality of the EPSS.
NFPA 110 also emphasizes considering a portable or alternate power source whenever the emergency generator is out of service. This consideration is essential for maintaining operational continuity and minimizing downtime during maintenance or unexpected outages.
Moreover, the 2025 edition recommends implementing reliability-centered maintenance (RCM) without compromising the objectives outlined in Paragraph 8.1.1. RCM is a strategic and analytical approach that assesses systems and assets, defining their functions and evaluating their criticality and risks to facility operations. RCM optimizes maintenance strategies to apply the most effective methods for each system and asset. This comprehensive approach aims to enhance reliability, minimize downtime, and optimize maintenance costs.
Manuals, Special Tools, and Spare Parts (NFPA 110, 8.2)
Comprehensive documentation and the availability of necessary tools and spare parts are fundamental. Chapter 8.2 recommends that the manufacturer provide at least two sets of instruction manuals for all major EPSS components.
Ensuring these manuals are readily accessible enables maintenance personnel to perform their tasks efficiently and accurately. One set of manuals should be kept near the equipment, and another should be kept in a separate, secure location. This dual-storage approach ensures that critical information is always available, even if one set is misplaced or damaged.
Additionally, special tools and testing devices necessary for routine maintenance shall be available. The right tools minimize downtime and ensure that maintenance tasks are performed promptly and effectively.
The availability of spare parts is equally important. NFPA 110 suggests maintaining a stock of replacement parts identified by experience as high-mortality items. Consideration should also be given to stocking spare parts as the manufacturer recommends.
Maintenance and Operational Testing (NFPA 110, 8.3)
A systematic routine maintenance and operational testing program should be initiated immediately after the EPSS has passed acceptance tests. Or after any repairs that impact the system’s operational reliability.
The maintenance and testing schedule should cover all major components to guarantee continued performance and adherence to safety standards. Key elements of the routine maintenance and testing program include establishing a written schedule for regular inspections and tests. This schedule should encompass the entire EPSS.
Operational Inspection and Testing (NFPA 110, 8.4)
Regular operational inspections and testing are integral to maintaining the reliability and functionality of Emergency Power Supply Systems (EPSS). These procedures ensure that all EPSS components are in good working order and ready to perform when needed.
Level 1 systems should be inspected weekly. Level 2 systems should undergo visual inspections at least monthly. These routine inspections help identify potential issues early, allowing for timely maintenance and repair.
Monthly exercises under load are crucial for verifying the EPSS’s functionality. For Level 1 and Level 2 systems, the EPSS should be exercised under load at least monthly.
Diesel generators should be exercised using methods that maintain minimum exhaust gas temperatures or under operating temperature conditions. If the diesel-powered EPS installations do not meet these requirements, they should be exercised annually for specified durations.
Records (NFPA 110, 8.5)
Maintaining detailed and accurate records is critical to the EPSS’s maintenance and operational testing program. Records should be created and maintained for all EPSS inspections, operational tests, exercises, repairs, and modifications. These records help facility managers track performance and reliability over time and identify recurring issues needing more in-depth investigation.
Records should be retained for a period defined by facility management or as specified by the authority having jurisdiction. This is essential for ongoing compliance and providing a comprehensive history of the EPSS’s maintenance and operational status.
Conclusion
The 2025 edition of NFPA 110 introduces several critical updates and enhancements compared to the 2010 edition. Some updates have been made to maintenance rules for fuel cell systems. There are also improved battery testing methods. Automated monitoring systems have been added. Additionally, load test criteria have been updated.
Understanding and implementing these latest standards is crucial for ensuring the safety and reliability of emergency power systems.
