In EV fires, a single tool is rarely sufficient. The FIREISOLATOR concept consists of multiple coordinated steps to quickly bring the situation under control, reduce secondary damage, and enable safer cooling and monitoring.
Fire blanket
Aerosol
Water mist cooling
Thermal camera
EV Firegun / immersion container option
Insulation
The fire blanket seals the space, reduces the spread of flames and heat, and provides time for safe intervention.
Containment
Unit used under the blanket - the aerosol - helps suppress flames, while water mist cools and reduces smoke/vapor load.
Targeted cooling and follow-up
A thermal camera helps identify remaining critical heat zones. If needed the Firegun is used for targeted battery cooling, followed the cooling for long-term stabilization by immersion container.
Potassium nitrate-based aerosol interferes with the combustion chain reaction using fine particles. It is effective under a blanket, where the required “space” is created for operation.
Up to 45 m³ coverage in enclosed space
15-year lifespan under specified conditions
Minimal residue, easier post-cleaning
Primarily for trained responders recommended
Water mist applied over the blanket helps cool the vehicle surroundings and reduce toxic vapor and smoke exposure. This is especially valuable in enclosed spaces where secondary damage escalates quickly.
Spraying onto the blanket for improved sealing and cooling
Targeted cooling of critical points based on thermal imaging
Continuous monitoring for re-ignition risk
When thermal imaging indicates the battery compartment is critical, the Firegun is used for targeted cooling of the cell area. In many protocols, full cooling is completed by placing the vehicle in an immersion container for multi-day underwater cooling to reduce re-ignition risk.
