When this happens, fire is a common result and explosions are possible. Several recent incidents in large BESS installations demonstrate how sizable BESS fires can be, how difficult they are to extinguish, and how they ca...See more on statx Gexcon

A total immersion concentrated aerosol fire suppression system is recommended for BESS facilities. Traditional fire suppression agents may be ineffective against BESS fires, but condensed aerosol agents such as Stat-X have been shown to be effective in rapidly suppressing fires, limiting the spread of thermal escape, and preventing rekindling.
Separation distances provided between BESS cabinets can also be used as a passive mitigation technique to reduce the thermal exposure from a fire event and limit container-to-container propagation, as proven by FM Global large-scale fire test (Ditch & Zeng, 2020). Typical fire hazard mitigation techniques are shown in Figure 5. Figure 5.
Regulatory Compliance: Adherence to updated standards such as NFPA 855 and UL 9540A ensures that newer BESS installations include fire safety features designed to limit fire initiation and propagation, therefore reducing potential environmental impacts in the event of a fire.
This hybrid approach is particularly useful in large-scale energy storage facilities, where electrical safety is a top concern. While water-based suppression is effective for temperature control, it is often used alongside other fire suppression methods for full containment of lithium-ion battery fires.
