In the previous parts, we showed that EV fires behave differently from fires involving internal combustion vehicles and that the suppression of visible flames often does not mean the end of the risk. Persisting temperatures, the risk of re-ignition, and the release of toxic gases make EV fires a complex, multi-phase event.
For this reason, it is increasingly clear that when dealing with electric vehicles, it is not sufficient to rely on a single tool or a single response step. The effective management of an EV fire requires a coordinated system of measures that complement one another.
A fire blanket addresses only part of the EV fire challenge
Every tool used in EV fire incidents addresses only part of the overall challenge. For example, fire blankets can be highly effective in isolating the vehicle and preventing the spread of fire to the surroundings, but they do not stop the reaction occurring inside the battery itself.
Similarly, it applies that:
suppressing flames does not automatically resolve battery overheating
external cooling may not reach the source of the problem
waiting without active monitoring introduces uncertainty
An EV fire therefore cannot be resolved through a single intervention. It requires a step-by-step approach that responds to the individual phases of the incident.
Key elements of a modern EV fire response system
Vehicle isolation
Rapid separation of the burning vehicle from its surroundings in order to prevent fire spread and reduce thermal exposure to the environment.
Cooling and environmental control
Reduction of temperatures, limitation of smoke and toxic gases, and improvement of conditions for a safe response, particularly in enclosed spaces.
Flame suppression
Use of appropriate extinguishing agents to limit open flames and reduce temperatures during the initial phase of the incident response.
Monitoring
Continuous monitoring of temperature and vehicle condition, enabling better decision-making regarding further actions and reducing the risk of unexpected developments.
Direct intervention in the battery
One of the most challenging aspects of EV fires is the fact that the source of the problem is located inside a closed battery module. For this reason, solutions are used in practice that allow responders to penetrate the battery and address it from within.
These include various types of devices capable of:
mechanically penetrating the protective battery casing
delivering extinguishing or cooling agents directly to the heat source
supporting faster temperature reduction and battery stabilization
Such tools exist in different technical designs and are primarily used in situations where there is a high risk of re-ignition or where it is necessary to actively address internal processes within the battery.
The importance of training and procedures
Even the best technology on its own is not sufficient if it is not part of a clearly defined procedure. EV fires place high demands on decision-making, coordination, and the safety of responding personnel.
For this reason, a system-based approach must also include:
staff training and education
clearly defined scenarios for different types of environments
predefined procedures following flame suppression
It is precisely the combination of technical measures and human preparedness that significantly reduces the risk of errors and unnecessary damage.
Why EV fires require a system-based approach
EV fires are not just a matter of extinguishing flames. They represent a safety, technical, and operational challenge that affects the functioning of buildings, infrastructure, and emergency services.
A system-based approach enables:
faster stabilization of the situation (for example, through the use of a fire blanket)
greater safety for responders and surrounding areas
better control of the risk of re-ignition
reduction of secondary damage and operational impacts
This is why EV fires are increasingly addressed not as isolated incidents, but as scenarios that require advance preparation.
