The purpose of NFPA 855 is to establish clear and consistent fire safety guidelines for energy storage systems, which include both stationary and mobile systems that store
Fire codes and standards inform energy storage system design and installation and serve as a backstop to protect homes, families, commercial facilities, and personnel,

However, many designers and installers, especially those new to energy storage systems, are unfamiliar with the fire and building codes pertaining to battery installations. Another code-making body is the National Fire Protection Association (NFPA). Some states adopt the NFPA 1 Fire Code rather than the IFC.
However, like any electrical infrastructure, energy storage systems come with their own set of risks, particularly fire hazards. This is where the National Fire Protection Association (NFPA) 855 comes in. NFPA 855 is a standard that addresses the safety of energy storage systems with a particular focus on fire protection and prevention.
In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.
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.
Owners of energy storage need to be sure that they can deploy systems safely. Over a recent 18-month period ending in early 2020, over two dozen large-scale battery energy storage sites around the world had experienced failures that resulted in destructive fires. In total, more than 180 MWh were involved in the fires.
