4 FAQs about Fire protection standards for energy storage equipment

What are NFPA 855 requirements for energy storage systems?

Electrical and Wiring Safety – Proper electrical wiring and connections are critical for fire safety in energy storage systems. NFPA 855 outlines specific requirements for cable management, grounding, and circuit protection to ensure that electrical components do not pose a fire risk.

Does NFPA 855 require a fire suppression system?

One proposal for the 2026 edition of NFPA 855, Standard for the Installation of Stationary Energy Storage Systems, would forbid installation of traditional clean-agent or aerosol fire suppression systems unless testing demonstrates that use of such systems does not create an explosion risk.

Are energy storage systems safe?

Energy storage systems, while essential for grid stability and renewable energy integration, present unique challenges when it comes to fire safety. Issues like thermal runaway, short circuits, and the flammability of certain materials can result in fires that are difficult to manage due to the stored energy within the system.

How do energy storage facilities maintain safety?

Energy storage facilities are monitored 24/7 by trained personnel prepared to maintain safety and respond to emergency events. Facilities use multiple strategies to maintain safety, including using established safety equipment and techniques to ensure that operation of the battery systems are conducted safely.
