Here at CheckFire, we are passionate about new product development and bringing innovative solutions to the market that target the fire risks that we are subject to as part of every day life. The CommanderEDGE LFX range has been specifically designed to tackle lithium-ion battery fires across a wide range ... Read more of applications. In addition to primary fire risks, the LFX fluorine-free range of fire extinguishers also protect from secondary A-class fires that have been caused by the exploding batteries.

When lithium-ion batteries malfunction, overheat, or are damaged, they can enter a dangerous state known as thermal runaway. This is an uncontrollable chain reaction of self-heating that can release toxic flammable gases – often igniting and triggering fires that spread rapidly through all battery cells, and even to surrounding materials.
Standard fire extinguishers – such as foam, CO?, and dry powder – are typically ineffective against this type of fire. That’s because they are not designed to deal with the intense heat, rapid gas release, and re-ignition potential that come with lithium-ion battery fires.
The CommanderEDGE LFX range, by contrast, is purpose-built to neutralise these risks. Its water-based, fluorine-free fire extinguishing agent forms a foam that sticks to battery surfaces, absorbs heat rapidly, and draws heat out of batteries – halting thermal runaway before it can escalate.
Because it cools both active and neighbouring cells, LFX fire extinguishers help prevent further explosions, limit toxic gas release, and reduce collateral damage, including from secondary A-class fires.
As the lithium-ion battery ecosystem expands to include electric tools, e-bikes, scooters, laptops, medical devices, and more, responsible fire safety planning must evolve too. LFX offers a compliant and forward-looking solution – especially relevant now that many battery-involved devices are becoming standard in workplaces and households.
Vaping devices also often use lithium-ion batteries, which can be volatile and catch fire or explode if damaged, overcharged, or exposed to high temperatures. It is therefore vital for organisations and workplaces to adopt clear fire-safe vaping policies. – for example, designating appropriate vaping zones away from fire alarm sensors or high-risk areas, and clearly signposting where vaping is permitted or prohibited. Proper disposal and battery recycling procedures (rather than throwing used vapes or batteries in general waste) further reduce the risks of malfunction or ignition.
Lithium-ion battery fires are no longer confined to specialist or high-risk environments. From offices, schools, and healthcare settings to warehouses and retail spaces, battery-powered devices are now embedded in everyday operations. This widespread adoption creates a mismatch between modern fire risk and traditional fire safety assumptions, with many existing fire safety strategies never designed to account for the way these fires develop. When incidents occur, they can escalate quickly, release toxic smoke, and compromise escape routes in occupied spaces.
Recognising that lithium-ion battery fires behave differently – and can occur in almost any setting – is the first step in closing the gap between perceived risk and effective response. This understanding underpins the need for specialist solutions like LFX, designed specifically for the realities of modern environments.
