🚨 New ISO Standard Recognises Lithium-Ion Battery Fires as Class L – Time to Update Your Risk Assessment? 🚨

Lithium-ion batteries power EVs, e-bikes, tools, laptops, warehouses and more – but when thermal runaway kicks in, ordinary extinguishers get overwhelmed and fires often reignite dangerously.

Big news: ISO has just published the revision to ISO 3941 “Classification of fires”, introducing a brand-new Class L specifically for lithium-ion battery fires. This follows recommendations from the Fire Industry Association’s Lithium-ion Battery Special Interest Group and reflects the real, growing risks we’re all facing in this battery-driven world.

Class L fires are electrochemical beasts – higher energy density, faster growth, toxic gases, explosion potential and stubborn re-ignition. Treating them like standard Class A, B or electrical fires is no longer good enough.

At FST Fire Compliance & Security, we install specialised LFX Lithium Fire Extinguishers that are built for exactly this: they cool burning cells, encapsulate electrolytes, block oxygen, halt thermal runaway and prevent re-ignition – unlike generic agents. Non-toxic, eco-friendly and dead simple to use.

Don’t wait for an incident to find out your current setup falls short. A proper lithium battery fire risk assessment is now more critical than ever for compliance, protecting people, assets and your operations.

Is your site, fleet or facility ready for Class L risks? Drop a comment below or DM us – we’ll sort a no-obligation risk assessment and tailored extinguisher installation.
