Chilly Temps, Charged Dangers: Lithium-Ion Battery Safety
Personal Lines Lead
The use of lithium-ion batteries is rising—and so are the potential hazards linked to them. Known for powering everything from smartphones to electric vehicles, when damaged, these batteries can enter a state of “thermal runaway,” a dangerous condition that leads to hotter, more challenging and intense fires, posing a significant risk for commercial property management.
The Risk of Flood Damage
Flooding introduces a significant and often underestimated danger to lithium-ion batteries, particularly those in electric vehicles (EVs) and larger devices. When submerged, the water can trigger chemical reactions within these batteries, leading to short circuits, thermal runaway, or delayed fires that occur days or even weeks later.
Saltwater poses a heightened risk compared to rainwater due to its high conductivity, which accelerates chemical reactions and increases the likelihood of thermal runaway or ignition. However, rainwater flooding is also hazardous. While less conductive, rainwater can still cause short circuits, compromise protective systems, and lead to component corrosion over time. Regardless of the water source, any submerged lithium-ion battery should be treated with caution and professionally inspected before further use.
Why these fires are dangerous
Lithium-ion battery fires are becoming more common, with over 25,000 incidents reported in five years. Lithium-ion battery fires burn hotter and longer than regular fires and can reignite even after being extinguished. They produce toxic smoke and require large amounts of water to control, straining emergency response resources. Proper care and storage are crucial to avoid these hazards.
Preventative measures
To reduce the risks associated with lithium-ion batteries during and after floods, consider these precautions:
- Move Vehicles and Devices to Higher Ground: Keep EVs, golf carts, and other battery-powered equipment away from flood-prone areas.
- Inspect Batteries Post-Flooding: If your property has been affected by flooding, have professionals inspect any devices or vehicles with lithium-ion batteries for damage before use.
- Dispose of Damaged Batteries Properly: Contact local hazardous waste management to safely dispose of compromised batteries.
- Educate Your Team: Ensure property managers, tenants, and staff understand the risks and safety measures associated with lithium-ion batteries.
General storage tips for lithium-ion batteries
Safe storage is crucial to minimize risks, especially during colder months or severe weather:
- Charge Partially: Keep batteries at 40-60% charge to reduce stress.
- Avoid Extreme Temperatures: Store in a dry, climate-controlled area between 59°F and 77°F.
- Use Fire-Safe Containers: Enclose batteries in fireproof bags or cases for added safety.
- Disconnect or Remove Batteries: For vehicles or devices, disconnect the battery to prevent discharge.
- Check Regularly: Inspect for swelling or damage and maintain a consistent temperature.
Key Takeaways
Lithium-ion batteries offer incredible convenience but come with serious risks if mishandled, especially in flood-prone areas. By taking preventive measures and practicing proper care, you can mitigate these hazards and protect your property from potential disasters.
