AVD Fire

AVD Fire is a global leader in lithium-ion battery fire protection, supporting the railway industry as it transitions towards electrification, battery-powered rolling stock, and energy storage systems. 

As rail operators and OEMs adopt battery-electric and hybrid technologies, the risk of lithium-ion battery fires has become a critical safety challenge. Unlike conventional fires, lithium-ion incidents involve thermal runaway, rapid heat escalation, and a high risk of re-ignition, making traditional fire suppression methods less effective. 

AVD Fire’s patented Aqueous Vermiculite Dispersion (AVD) technology is specifically engineered to address these challenges. The agent works by rapidly cooling battery cells while forming a heat-resistant barrier that prevents oxygen from sustaining combustion, effectively suppressing fires and reducing the risk of re-ignition. 

AVD Fire solutions are designed for deployment across a wide range of rail environments, including rolling stock, maintenance depots, railway stations, and trackside infrastructure. Our product range includes lithium-ion fire extinguishers, EV and industrial fire blankets for fire containment, and specialist suppression systems for battery storage and charging areas. 

Key applications within the rail sector include battery-powered trains, hybrid locomotives, depot vehicles, signalling systems, and passenger environments where lithium-ion devices are increasingly present. In these settings, rapid response and effective containment are essential to protect passengers, staff, and critical infrastructure. 

AVD Fire’s approach focuses on both suppression and containment, recognising that lithium-ion battery fires require more than conventional firefighting methods. By preventing thermal runaway escalation and re-ignition, AVD Fire solutions help rail operators maintain safety, minimise disruption, and protect assets. 

With increasing regulatory focus and the continued growth of electrified transport, AVD Fire provides rail operators, infrastructure managers, and OEMs with the tools and expertise needed to manage lithium-ion fire risk effectively.
