Energy storage fire fighting function entry and exit

Do fire departments need better training to deal with energy storage system hazards?

Fire departments need data, research, and better training to deal with energy storage system (ESS) hazards. These are the key findings shared by UL’s Fire Safety Research Institute (FSRI) and presented by Sean DeCrane, International Association of Fire Fighters Director of Health and Safety Operational Services at SEAC’s May 2023 General Meeting.

What are the fire and building codes for energy storage systems?

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.

What is battery energy storage fire prevention & mitigation?

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.

How do ESS fire protection systems work?

While these layers of protection help prevent damage to the system, they can also block water from accessing the seat of the fire. So, large amounts of water are needed to effectively combat the heat generated from ESS fires, and cooling the hottest part of the fire is often difficult.

Why are building and fire codes important?

Before diving into the specifics of energy storage system (ESS) fire codes, it is crucial to understand why building and fire codes are so relevant to the success of our industry. The solar industry is experiencing a steady and significant increase in interest in energy storage systems and their deployment.

Does NFPA 855 permit alternative fire suppression systems?

NFPA 855 also permits the use of alternative fire suppression systems if they successfully pass large-scale fire testing in accordance with Underwriters Laboratories (UL) 9540A, “Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems,” or an equivalent standard.
