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.

Why is fire suppression a last line of Defense?

Fire suppression is the last line of defense in battery energy storage systems. The discharge of agent indicates that all other interventions have failed. This is because the nature of battery failures and their design make total extinguishment challenging. After gas detection, the next opportunity for fire detection is by the production of smoke.

How did the FSRI mitigate ESS hazard?

The deflagrations were mitigated with an engineering deflagration protection system designed as per the NFPA 68 Standard on Explosion Protection by Deflagration Venting. From these test findings, the FSRI developed two tactical considerations for responding to and mitigating ESS hazards.

How long did it take for fire crews to open the BESS container?

Approximately three hours after arrival, fire crews opened the doors to the still-smoking container. The fire department was called and arrived on scene. Smoke was observed coming from a lithium-ion BESS container at Arizona Public Service's solar array site in Surprise, Arizona.

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.
