The 2026 Edition of NFPA 855 Changes ESS Rack Design and Traceability Documentation at the Same Time
The 2026 edition of NFPA 855 shifts the center of gravity of ESS (Energy Storage System) safety standards from preventing ignition at the cell level to Thermal Runaway Propagation Prevention (TRPP) at the rack/container level. This revision is a line/system-engineering matter, not a problem of the battery's own material properties, in that it brings the entire BOS (Balance of System) — including cell-to-cell spacing, detection interfaces, and cooling wiring — into the scope of design. At the same time, mandatory pre-submission of the HMA (Hazard Mitigation Analysis) and ERP (Emergency Response Plan) to fire authorities has made a Traceability system that tracks and retains design-basis data at the rack level…

K-BATTERY SHOW 2026 Fire Safety Seminar: What to Look for in a Line-Level Fire Response System
K-BATTERY SHOW 2026 was held from September 9 to 11, 2026, in Hall 7 of KINTEX Exhibition Center 2, with 185 exhibiting companies and 15,311 visitors over three days. The exhibition featured a special EV fire-response pavilion gathering fire prevention, detection, and suppression technologies, and the SFPE Korea Chapter’s “2026 International Lithium Battery and EV Fire Safety Seminar” shared thermal-runaway prediction and suppression technologies. This article treats line-level fire response as a closed loop of three serially connected segments (detection, isolation, and suppression) and shows that, in an assumed scenario, suppression-discharge delay accounts for 54 % of the loop’s total response time of 18.5 s. In other words, the performance…

NFPA 855 (2026 Edition) Revision: ESS Safety Standards Expand From the Cell to the Entire System
Since August 2017, 21 lithium-ion battery ESS fires have occurred in Korea alone, but only a portion of these incidents can be explained by battery cell defects alone. In many cases, the direct cause of fire spread was equipment outside the battery itself — the Balance of System (BOS) — such as missing surge arresters, defective wiring installation, or cooling/HVAC failures. With the release of the 2026 edition of NFPA 855, the National Fire Protection Association (NFPA) has shifted its evaluation criterion from "whether an internal cell defect exists" to "whether propagation to adjacent cells, modules, or racks is blocked." NFPA 855 is the Standard for the Installation of Stationary…
