The Growing Risk of Lithium Battery Fires
Lithium ion batteries are now part of everyday life, powering e-bikes, e-scooters, laptops, tools, phones, cleaning equipment and rechargeable workplace devices. While these batteries are efficient and convenient, they can create serious fire risks if they are damaged, poorly manufactured, incorrectly charged or used with unsuitable chargers.
London Fire Brigade warns that lithium ion batteries in e-bikes and e-scooters can pose a serious fire risk when damaged, faulty or charged incorrectly, and that battery failures can ignite quickly, spread rapidly and produce toxic smoke. London Fire Brigade’s e-bike and e-scooter fire safety advice highlights why this issue is now a major concern for homes, landlords, schools and commercial premises.
Why Electrical Safety Checks Are Now More Important
As more battery powered devices are used and charged on site, businesses need to think beyond the device itself and consider the electrical infrastructure supporting it. Overloaded sockets, damaged accessories, unsuitable extension leads, poor charging locations and outdated distribution systems can increase risk.
Regular electrical inspections help identify issues before they become dangerous, especially in busy environments such as offices, schools, hospitality venues, workshops and communal buildings. Azure Electrical supports businesses with Electrical Statutory Compliance, including inspections, testing and certification designed to help sites stay safe, compliant and properly documented.
The HSE also provides workplace electrical safety guidance, reinforcing the need for electrical systems to be safely maintained. HSE electrical safety guidance is a useful external resource for dutyholders managing workplace risk.
What Causes Lithium Battery Fires?
One of the biggest concerns with lithium ion batteries is thermal runaway, a chain reaction where the battery overheats and can lead to fire, explosion or the release of toxic fumes. Electrical Safety First explains that thermal runaway is a major battery safety risk and can be linked to damaged, poor quality or incorrectly charged batteries.
Their guidance recommends checking batteries for dents, deformation or overheating, using the correct manufacturer approved charger and avoiding continuous charging once the charge cycle is complete. You can read their advice on lithium ion battery safety and e-bike battery safety
The Commercial Risk for Schools, Landlords and Businesses
For commercial sites, lithium battery fire risk is not just a health and safety issue. It can affect insurance, compliance, business continuity and emergency planning. Devices charged in corridors, communal areas, plant rooms or escape routes can create serious risks if a fire starts.
London Fire Brigade advises that batteries should be charged on hard, flat surfaces where heat can dissipate and should not be stored or charged where they could block a main route or exit. Their safe charging guidance is particularly relevant for schools, landlords, offices and shared buildings. Azure Electrical’s commercial electrical services help organisations assess existing systems, complete remedial works and improve the safety of electrical infrastructure across active sites.
