Can a gas suppression system put out a fire without damaging equipment?

Unlike water, powder, or foam fire suppression systems, gas suppression systems can put out fires without damaging equipment. Some gaseous fire suppression systems do not require any clean up at all after they put out a fire. There are several different kinds of gases that can be used to suppress a fire.

What are the challenges associated with Li-ion battery fire suppression systems?

(49) The major challenges associated with Li-ion battery fire suppression systems are the probability of re-ignition after cessation of the fire suppressant release and continued thermal runaway propagation in battery packs, modules, and battery systems. (49,50)

Can lithium-ion battery ESS be used for fire suppression and explosion prevention?

Recommendation: Research and testing on fire suppression and explosion prevention systems for lithium-ion battery ESS should address project sites over an extended period of time.

Are battery energy storage systems safe?

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.

What extinguishing agents are used in a battery fire?

Gaseous extinguishing agents, such as carbon dioxide, Halon-based, HFC-227ea, and Novec 1230, have also been used for suppression of Li-ion battery fires.

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.
