How to protect you and your property from the risks of Lithium-Ion Batteries
Lithium-ion batteries power everything from electric vehicles to phones and power tools. Their high energy density makes them indispensable – but it also means they can pose a significant fire risk when damaged, poorly maintained, or improperly stored. Recent incidents, including at least one major loss, indicate a concerning trend in lithium-ion battery related fires.
To help minimise these risks, we’ve outlined key guidelines for safe storage, handling and emergency preparedness.
Storage Guidelines
Store in a cool, dry, well-ventilated area. Ideal storage temperatures range from 5°C to 20°C. Avoid exposing batteries to extreme temperatures, which can reduce performance and increase the risk of thermal runaway.
Store batteries away from combustible materials. Consider using metal storage cabinets. For added protection or dangerous goods, measures are well separated (10 metres plus) from other property. Implementing an automatic fire alarm system with smoke and carbon monoxide detectors in storage areas can provide early warning of potential fires.
Separate fresh and depleted batteries to prevent confusion and potential hazards. Keeping a log of battery status can help manage this process effectively. Treat damaged or dropped batteries as unstable hazardous goods until they have been tested safe by a qualified technician.
Avoid storing large quantities of batteries. Bulk storage should be confined to designated, well-equipped storage facilities.
Handling Guidelines
Ensure all staff handling lithium-ion batteries have appropriate training. They should understand the risks associated with these batteries and know how to handle them safely. Well-documented and circulated Standard Operating Procedures that clearly articulate what’s expected and monitor the management of these items will become a focus for insurers.
Provide appropriate PPE, such as gloves and safety glasses, to protect against potential battery leaks or explosions.
Regularly inspect batteries for signs of damage, such as swelling, leaks, or corrosion. Damaged batteries should be disposed of properly and not used.
Only use chargers compatible with the specific type of lithium-ion battery. Overcharging or using incorrect chargers can lead to overheating and potentially fires. Often, insurers require battery charging in designated areas with fire and heat retarding wall linings and a safe heat escape design.
If a battery is damaged, handle it with extreme caution. Place it in a non-combustible container, well separated from other structures (at least 10 metres) and contact a professional disposal service.
Emergency Procedures
In case of a battery fire, use a Class D fire extinguisher designed for metal fires only when safe to operate. Extreme caution should be applied due to the risks of explosion. Water should not be used as it can exacerbate the fire.
If a battery leaks, evacuate the area and ventilate it thoroughly. Use appropriate PPE to clean up the spill and dispose of the battery according to local regulations.
In case of exposure to battery chemicals, seek immediate medical attention. Rinse any affected skin or eyes with plenty of water and remove contaminated clothing.
With appropriate training, regular inspection, and well-designed storage and charging practices, the risks associated with lithium-ion batteries can be significantly reduced. These measures support safer workplaces and help protect people, assets, and business continuity.
