With the rise of electric vehicles (EVs) and other devices powered by lithium-ion batteries, a significant fire risk has emerged. These batteries, found in everything from smartphones and e-scooters to EVs, can ignite or even explode under certain conditions. Lithium-ion battery fires are especially dangerous because they can be extremely challenging to extinguish, making them a serious concern in enclosed spaces like car parks, ferry decks, and buildings. A fire of this nature in a confined space could lead to catastrophic consequences.
Why Lithium-Ion Battery Fires Are So Challenging
EV fires can reach temperatures exceeding 1500 °C, far hotter than typical fires from combustion engines. This heat intensity and the risk of chemical chain reactions make them particularly difficult to control with traditional firefighting methods like water alone. For fire safety professionals, the challenge is to contain and mitigate such fires while reducing collateral damage to nearby property and ensuring the safety of individuals in the vicinity.

Key Considerations for Managing EV Fires
Given the unique hazards of lithium-ion battery fires, specialized training and equipment are essential for anyone working around EVs, particularly on ferries or in large car parks where fires can spread rapidly. Being trained in the various steps needed to respond to EV fires can make a critical difference in an emergency. Understanding and implementing the right firefighting strategy, depending on the fire’s location and size, is paramount.
The Birth of the Fire Isolator Concept
Through extensive live tests and experience in fighting EV fires, specialists have developed the Fire Isolator Concept, a comprehensive approach designed to combat lithium-ion battery fires effectively. This concept is based on the principle that no single solution can fully extinguish an EV fire; instead, multiple strategies must be combined to yield the safest, most effective results. By using a carefully curated set of tools and techniques, the Fire Isolator Concept aims to contain and control fires with minimal damage to people and property.
The Five Elements of the Fire Isolator Concept
- High-Temperature Fire Blanket: A specially designed fire blanket can withstand extremely high temperatures, helping to isolate the fire and prevent it from spreading.
- Water Mist Lance: Spraying a fine mist of water can cool the flames and reduce toxic fumes, making the area safer for first responders.
- Aerosol Units: These units interrupt the chemical chain reactions within the flames, reducing the fire’s temperature and limiting its intensity.
- Training: Proper training is critical. Personnel must know how to use these tools effectively to respond to EV fires safely.
- Thermal Imaging Camera: A thermal camera allows responders to monitor the fire’s temperature, providing essential data to inform response actions and helping to gauge when the fire is under control.
Conclusion
The Fire Isolator Concept represents a comprehensive solution for managing the unique hazards of lithium-ion battery fires. By combining a fire blanket, water mist lance, aerosol units, specialized training, and thermal imaging, this concept offers a layered defense against EV fires. As the use of lithium-ion batteries continues to grow, so too does the need for innovative approaches to fire safety. The Fire Isolator Concept provides a powerful method to contain these challenging fires, protecting lives, property, and critical infrastructure in an increasingly electrified world.
