Browse All ProductsKey Risk Zones
Traction Battery Packs
High-voltage lithium-ion traction batteries powering electric and hybrid rolling stock are a primary fire risk — thermal runaway in a single cell can cascade rapidly through the entire pack.
Passenger Carriages
Personal devices, e-cigarettes, and e-bikes carried by passengers introduce uncontrolled lithium battery risks into enclosed, high-occupancy carriages where evacuation is difficult.
Driver Cab & Electronics
Control systems, backup power units, and cab-mounted devices contain lithium batteries that, if compromised, can disable critical safety and communication systems.
Depots & Maintenance Bays
Battery charging, storage, and replacement activities in depots create concentrated fire risk zones — a thermal runaway event in a confined maintenance bay can spread rapidly.
Underground & Tunnel Networks
Below-ground rail environments present the most severe risk — limited ventilation, restricted evacuation routes, and the buildup of toxic gases from battery fires are life-threatening hazards.
E-Bike & Scooter Storage
Many rail operators now accommodate e-bikes and e-scooters in dedicated carriages and station storage areas, introducing large-capacity lithium batteries into public transit infrastructure.
How AVD Fire Suppression Works
Lithium-ion battery fires are unlike any conventional fire — they progress rapidly, release toxic gases, generate extreme heat, and can reignite days or even weeks later. Standard extinguishers are ineffective against thermal runaway. AVD (Aqueous Vermiculite Dispersion) is a revolutionary, certified extinguishing agent developed specifically to tackle these unique challenges — cooling cells, suppressing flames, and forming a physical barrier to prevent reignition.
Learn About AVD TechnologyAVD Is Applied To The Battery
AVD is discharged directly onto the lithium-ion battery using standard fire-fighting equipment — from portable extinguishers to large-volume trolley units and fixed suppression systems.
Rapid Cooling Of Battery Cells
The aqueous component immediately cools the battery cells, reducing the intense heat generated during thermal runaway and slowing the chain reaction within the cell.
Flames Are Suppressed
AVD acts to suppress the flames and extinguish the fire quickly, limiting the damage and losses caused by a rapidly propagating lithium-ion battery fire.
A Thermal Barrier Forms
As the water evaporates, a heat-resistant layer of vermiculite mineral deposits onto the battery surface, forming a physical oxygen and heat barrier to prevent reignition.
Thermal Propagation Is Blocked
AVD's non-flammable properties reduce thermal propagation between battery cells. It can also be applied as a fire break to prevent the fire spreading to surrounding materials and property
Safe, Clean & Non-Toxic
AVD contains only water and naturally occurring vermiculite mineral — it is PFAS-free, environmentally friendly, non-toxic to humans, animals, and plant life, and leaves no harmful residue.
