Lithium-ion batteries are now embedded in almost every part of modern life, from mobile phones and power tools to electric vehicles, public transport and large-scale energy storage systems. But as this technology becomes more widespread, are fire and rescue services keeping pace with the risks?

Recorded live at the World Fire Congress 2026 in London, this episode of The Firefighters Podcast features Dr Stephen Kerber of UL Research Institutes and the Fire Safety Research Institute (FSRI), one of the leading voices in research-led firefighter safety.

Stephen explores the increasing operational challenges associated with lithium-ion batteries, the hazards that can emerge throughout their lifecycle and the diverse environments in which firefighters are now encountering them.

Of particular concern is the potential for flammable battery gases to accumulate within enclosed compartments, creating conditions for deflagration.

But this conversation is about more than understanding the hazards. It's about translating scientific research into better education, improved standards, more effective operational preparation and greater public awareness.

As lithium-ion technology continues to evolve, our understanding, training and response must evolve alongside it.

An important listen for firefighters, incident commanders, trainers, fire safety professionals and anyone involved in preparing our services for emerging risks.
