Silent energy storage firefighting

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.

Do lithium-ion battery energy storage systems cause fires?

The report is a culmination of a two-year research project examining the characteristics of fires resulting from the overheating of lithium-ion battery energy storage systems (ESS) within residential structures.

Who released the 'Considerations for Fire Service Response' document?

The International Association of Fire Fighters (IAFF), in partnership with UL Solutions and the Underwriters Laboratory’s Fire Safety Research Institute, released “Considerations for Fire Service Response to Residential Battery Energy Storage System Incidents.”

What are the standards for ESS fire suppression systems?

Two commonly referenced standards for ESS fire suppression systems are FM Global Data Sheet (FM DS) 5-33 and NFPA 855. In the event of thermal runaway, it is essential to rapidly cool the affected module and its surroundings to prevent a chain reaction of battery fires.

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.

How can I improve fire safety with ESS?

In addition, you can join a SEAC working group, including the Storage Fire Detection working group and the ESS Standards working group, that’s working to improve fire safety with ESS. Lastly, join SEAC for a virtual workshop on safety and risk considerations when permitting ESS.
