General Fire Isolator FAQ

  • What is the FIRE⚡️ISOLATOR concept?

The Fire Isolator concept is a comprehensive approach to isolating and fighting EV car fires, developed based on best practices and live testing. It combines a high temperature-resistant fire blanket, handheld aerosol units, and a water mist lance to effectively manage and minimize damages caused by such fires.

  • Why is there no single solution to extinguish EV car fires?

EV car fires involve complex lithium-ion batteries that require specialized methods to control and extinguish. Due to the unique challenges they pose, a combination of firefighting techniques is needed for effective containment. A thermal runaway in a lithium-ion battery cannot simply be stopped by taking the oxygen. As a result, a single fire blanket will not stop the thermal runaway but will prevent collateral damages.

  • What is the main goal of the FIRE⚡️ISOLATOR concept?

The primary objective of the Fire Isolator concept is to isolate and control EV car fires while minimizing collateral damage. It focuses on preventing the fire from spreading and reducing risks associated with toxic fumes and smoke.

  • How do you handle EV fires with the FIRE⚡️ISOLATOR concept?

Firstly, it must be emphasized that – generally speaking – EV fires are rare and significantly lower in frequency than gasoline or hybrid vehicles. The real risk, however infrequent, lies in the potential devastation of these hard-to-handle fires. Fires from Li-ion batteries used in EVs and hybrid cars can burn hotter and longer than gasoline fires and can take tens of thousands of liters of water to extinguish. Such fires can be triggered by damaged batteries, collisions, and during the charging of a defective battery.

When an EV fire occurs, however, using the traditional method to extinguish it, water, does not provide the same outcome as water does with combustion-engined cars. The burning lithium-ion battery cannot be extinguished by throwing water on it. It is of because of the risk of the fire continuing to burn and as a result spreading to other cars, a ship, or a building construction, that the Fire Isolator concept provides a better and more effective way to control such an EV car fire. When the focus shifts from ‘extinguishing’  to ‘ controlling’ , firefighters or crews need to change their mindset to minimize the collateral damages. This is where the true strength of the Fire Isolator concept lies.

The FIRE⚡️ISOLATOR concept comprises several proven elements:

  • High-temperature resistant car Fire Blanket to isolate and control the fire.
  • Handheld Aerosol units to suppress the flames and interrupt chemical reactions.
  • Water mist lance to reduce toxic fumes, smoke, and keep the car cooled.
  • Thermal imaging camera for enhanced situational awareness.
  • Training in the concept to ensure proper implementation.
  • What role does the Fire Blanket play in the concept?

The Fire Blanket is used to isolate and control the fire, preventing collateral damage. It can withstand high temperatures (up to 1600 degrees C°/ 2900 degrees ℉) and offers control over the situation, although it does not extinguish the battery fire by itself. Furthermore, by pulling the blanket over the car, it provides the ‘ confined space’  that the aerosol units need to be effective in kicking down the flames.

  • How do aerosol units contribute to the firefighting of electric vehicles in this concept?

Aerosol units interrupt chemical chain reactions in flames, suppressing the fire and reducing temperatures. This approach is vital in containing the fire and preventing its escalation.

  • What is the purpose of the water mist lance in the FIRE⚡️ISOLATOR concept?

The water mist lance has several purposes within our concept.

The water mist lance can be deployed to spray a fine mist over the Fire Blanket, which helps lower toxic fumes, smoke, and temperature levels. This contributes to keeping the situation under control and reducing hazards. By spraying a water mist over the blanket (car), the blanket becomes more gastight, increasing the effectiveness of the aerosol units.

The water mist lance can also be used to penetrate the battery pack and flood it with water from within. This takes for the fire fighting crew to first locate the battery pack and then penetrate that with the water mist lance.

  • Why is a thermal imaging camera used in this concept?

A thermal imaging camera enhances situational awareness by providing real-time visibility of temperature variations. This aids firefighters in assessing the fire’s progress and the effectiveness of their actions.

  • What is the significance of submerging the EV car in a dipping container?

Submerging the EV car in a dipping container for a period of time is an essential last step in fully extinguishing the fire and ensuring safety. This process helps to eliminate any remaining risks.

  • Is training provided for implementing the FIRE⚡️ISOLATOR concept?

Yes, training is a crucial component of the Fire Isolator concept. Firefighters are trained in the proper utilization of the concept’s elements to ensure effective firefighting and minimize potential dangers. We regularly organize training days. These trainings take a full day and are 50% theoretical and 50% hands-on with our concept: the blanket, the aerosol units and water mist lance. These training days can take place at one of our locations in the Netherlands or can be organized at a location of your preference, globally. Participants get a syllabus and a training certificate.

  • Who developed the FIRE⚡️ISOLATOR concept?

The Fire Isolator concept was developed by T-ISS Safety Suppliers from the Netherlands, together with a team of specialists with extensive experience in fighting EV car fires. Their expertise led to the formulation of this comprehensive approach to firefighting.

  • Has the FIRE⚡️ISOLATOR concept been tested?

Yes, the Fire Isolator concept has been thoroughly tested and proven to be effective in minimizing the collateral damages of an EV car fire. Extinguishing the fire (thermal runaway) in the lithium-ion batteries is close to impossible and can only be done by submerging the car in a dipping container. The Fire Isolator concept prevents collateral damage, brings down the fire’s temperature and wins you time to think about an extraction plan for the car. The concept’s elements have been certified (ISO EN 13501-1, ASMTD6413, ABS) and rigorously examined to ensure their functionality in real-world scenarios. You can view a compilation of various live fire tests from around the world in this video.

An aerosol unit is a handheld device used by first responders and firefighters to significantly reduce fires, primarily for class A, B, and C fires. It can be activated on the scene and thrown into the fire area to aid in fire reduction.

  • How does the aerosol unit work?

The aerosol unit contains solid microparticles, primarily potassium nitrate, which serves as an anti-catalytic agent. When activated, these particles drain energy from the fire, reducing its intensity.

  • How do you activate the aerosol unit?

To activate the aerosol unit, straighten the far ends of the pins and pull the pin out. A clicking sound confirms successful activation. The unit begins producing aerosol approximately 8 seconds after activation and discharges within 25 seconds. You can read more about this here.

  • What is the average hold time of the aerosol unit?

The average hold time, or time before re-ignition, is around 30 minutes. The hold time depends on factors like leakage and the amount of substance inserted, with smaller volumes leading to longer hold times.

  • Can the aerosol unit be used alone?

The aerosol unit is most effective when used in combination with other tools like the Fire Blanket and Water Mist Lance. These tools complement each other to enhance fire control.

  • How should aerosol units be used in EV car fires?

When dealing with EV car fires, aerosol units work best when thrown under the vehicle after covering it with the Fire Isolator fire blanket. This strategy ensures that the active substances remain under the blanket and enter the burning vehicle.

  • How does the Water Mist Lance contribute to using aerosol units?

The Water Mist Lance wets the Fire Blanket, making it harder for aerosol substances to escape. This helps enhance the effectiveness of the aerosol unit in controlling fires.

  • Is there a bracket for holding the aerosol unit?

Yes, there is a bracket on the side of the aerosol unit, designed to make it easy to hold and throw into the fire.

  • Is there any health concern associated with aerosol units?

While a normal concentration of aerosol particles is generally safe, inhalation of micro-sized particles may cause short-term discomfort. Unnecessary exposure should be avoided.

The aerosol units have a shelf life of 15 years. There is no yearly maintenance needed.

Water Mist Lance FAQ

  • What is a water mist lance and what is the role of it in the FIRE⚡️ISOLATOR  concept?

The Water Mist Lance is part of the Fire Isolator concept for controlling and fighting EV car fires. The lance has the ability to penetrate and flood EV car lithium batteries to cool down the batteries in case of fire. However, based on our own experiences and best practices, we advise to use the water mist lance as a way to spray a water mist over the blanket while it is on the burning EV. By doing this, the water mist makes the blanket even more dense, which increases the effect of the aerosol units. The ‘heavier’ and more dense the blanket is, the more confined the space is where the aerosol unit is active, meaning that leakage of the aerosol cloud is minimal.

Electric Vehicle Fires on Ships FAQ

  • Can EV car fires on ships be prevented?

No, it’s not possible to prevent EV car fires on ships completely, especially due to the presence of lithium-ion batteries that can enter into thermal runaway. However, the Fire Isolator concept offers a solution to effectively manage and mitigate the risks associated with such fires.

  • How should one handle an Electric Vehicle (EV) fire on a ship?

When faced with an EV fire on a ship, water alone isn’t sufficient to extinguish it. The ‘Thermal Runaway’ phenomenon keeps the fire alive inside the battery. Using a fire blanket to isolate the fire is crucial. It won’t extinguish the battery fire but prevents collateral damage. This step should be taken immediately after detecting the fire. Based on several tests performed by the LASH fire project, the best practice to control EV car fires on board ships (ferries and car carriers) is this: Detection of the fire – ventilation system switched off – drenching/deluge system activated – pull fire blanket over car to minimize the collateral damage – manual firefighting – keep surrounding cars wet and/or also pull a blanket over those cars.

  • What happens after the fire blanket is placed?

After placing the fire blanket over the car, aerosol units come into play. These units aim to interrupt the thermal runaway and suppress the fire’s intensity, while not fully extinguishing it. The water mist lance then sprays water mist over the blanket to reduce toxic fumes, and smoke, and further cool down the car.

  • Why is monitoring with a Thermal Imaging camera recommended?

Monitoring the car with a Thermal Imaging camera is advisable to keep track of the situation. This helps ensure that the fire remains under control and doesn’t escalate.

  • What does the FIRE⚡️ISOLATOR  concept aim to achieve?

The Fire Isolator concept aims to minimize collateral damage caused by EV car fires on ships. It focuses on isolating the fire to buy time for reaching a safe haven and unloading the vehicle without causing additional harm.

  • Can the FIRE⚡️ISOLATOR  concept be used for combustion engine cars as well?

Yes, the Fire Isolator concept has been successfully tested on both combustion engine cars and EVs. It offers a versatile solution to address fire risks in various types of vehicles.

  • How does the FIRE⚡️ISOLATOR  concept contribute to safety on ships?

By effectively managing EV car fires, the Fire Isolator concept enhances safety on ships carrying electric vehicles. It minimizes the chances of fires spreading and causing extensive damage. The use of high temperature-resistant fire blankets is now also included in the latest UK government guidelines for transporting EV’s onboard ships. Read more.

As a result, these shipping companies now have more equipment on board to fight any possible EV car fire.

Electric Vehicle Fires in parking garages FAQ

  • Are EV car fires different from a regular (combustion engine) car fire in a carpark?

If a regular, combustion engine, car catches fire in a parking garage, there are now means to extinguish it as soon as possible. Here ‘water’ is the key. However, that same water doesn’t do the job when it comes to putting out an electric vehicle. A lithium battery cannot be extinguished by spraying water over it or removing the oxygen. They can be extinguished by completely submerging the car in a submersible container, but this is either not available in a parking garage, or the car cannot be towed directly outside the parking garage to this container.

  • How are EV fires detected in parking garages?

We know of detection systems that are installed in parking garages that monitor the temperature of EV’s. When the temperature reaches 60-70°C (32°F) , this could indicate that a thermal runaway is imminent. The temperature at which the thermal runaway occurs depends on the cell size, cell materials en cell design and it may vary from 130°C to over 200°C. There are several companies that offer these types of monitoring systems. One such company is Siemens.

  • How is fire safety managed for electric vehicles in parking structures?

Despite the development of early detection systems that can alert the user when a lithium-ion battery is about to go in thermal runaway, we notice that these systems are often only implemented in the parking spots where EV’s are charged. It is true that the chance of a battery going into thermal runaway is bigger when the car is charged, there are also cases known where a battery goes into thermal runaway without being charged. So, knowing that an Electric Vehicle can park anywhere in the carpark, there is still the risk of big collateral damages if the fire is not detected early enough. The most ideal situation would be for the parking garage crew to be trained and equipped to pull the Fire Isolator blanket over the burning car as soon as possible. The sprinkler system (if available) will keep the surrounding cars wet, but will not be able to extinguish the thermal runaway in the battery of the EV. The challenge for fire fighters here is that pretty soon the carpark will be filled with smoke, which hinders visibility. Still, we strongly advise to pull the Fire Isolator blanket over the car, keep the car wet with a water mist, throw a handheld Aerosol Unit under the blanket to reduce the flames, and to keep the surrounding cars wet. If available, and keeping the blanket on the car, the car should be pulled out of the garage with a remote-controlled tracked robot. Once outside the parking, the car should be submerged under water in a dipping container.

  • How does a fire blanket and the Fire Isolator concept help contain electric vehicle fires in car parks?

By pulling over the Fire Isolator, high temperature resistant fire blanket over the (burning) car, the risk of big collateral damages is reduced. The blanket contains the fire. By the nature of carparks, they are places where lots of cars are parked near each other. There is also the risk of the fire affecting the building structure or piping systems. This is why it is essential to have the Fire Isolator concept (blanket, handheld potassium aerosol units, water mist) available on each floor of the carpark. When training and equipped with the right PPE, the parking garage crew can deploy our Fire Isolator concept. If it is needed to wait for the fire fighters to arrive at the garage, they need to have our concept available to be quickly and safely deployed.
