Stay Calm, Exit Safely: Immediately stop the car, turn it off, and evacuate all passengers
In the event of an electric vehicle fire, every second counts, and your first priority is to ensure the safety of everyone inside the car. The initial steps are deceptively simple but require a clear head and swift action. As soon as you notice signs of a fire—unusual smells, smoke, or warning lights—your immediate response should be to pull over to a safe location. This means steering the car to the side of the road, away from traffic, pedestrians, and flammable structures. The goal is to minimize risk to others while creating a safe exit path for yourself and your passengers.
Once stopped, turn off the ignition and power down the vehicle completely. In electric cars, this often involves shutting down the high-voltage system, which can typically be done via the emergency shut-off switch or the main battery disconnect. Consult your vehicle’s manual beforehand to familiarize yourself with these mechanisms, as they vary by make and model. Turning off the power reduces the risk of electrical arcing and can slow the fire’s progression, buying you precious time to evacuate.
Evacuating the vehicle is the next critical step. Unlike traditional gasoline fires, electric vehicle fires involve lithium-ion batteries, which can reignite and burn at extremely high temperatures. Do not hesitate—exit the car immediately, even if the fire appears contained. Assist children, elderly passengers, or anyone with mobility issues, but avoid wasting time retrieving personal belongings. The National Fire Protection Association (NFPA) recommends moving at least 100 feet away from the vehicle, as toxic fumes and sudden flare-ups pose significant dangers.
Staying calm is easier said than done, but it’s essential for executing these steps effectively. Panic can lead to poor decision-making, such as attempting to fight the fire yourself or delaying evacuation. Remember, electric vehicle fires are rare, but their unique risks require a specific response. By stopping the car, turning it off, and evacuating swiftly, you’re following the most critical safety protocol. Once everyone is safe, call emergency services and let trained professionals handle the situation. Your role is to prevent harm—to yourself and others—by acting decisively and without delay.

While waiting for emergency services to arrive, prioritize safety. Electric vehicle fires can escalate quickly, and the risks include thermal runaway, where the battery cells overheat and cause a chain reaction. Maintain a safe distance—at least 50 feet—to minimize exposure to toxic smoke and potential explosions. If occupants are still inside the vehicle, attempt to assist them out only if it’s safe to do so. Do not attempt to extinguish the fire yourself, as water and traditional fire extinguishers may be ineffective or even dangerous against lithium-ion battery fires.
A comparative analysis of EV fires versus gasoline fires highlights why calling emergency services is non-negotiable. Gasoline fires typically burn out once the fuel is depleted, but EV battery fires can smolder and reignite hours after being extinguished. Emergency responders are equipped with tools like thermal imaging cameras and specialized extinguishing agents (e.g., dry powder or copious amounts of water) to manage these challenges. By alerting them to the nature of the fire, you enable them to deploy the right resources and strategies from the outset.
In conclusion, calling emergency services is the cornerstone of responding to an electric vehicle fire. It’s a simple yet decisive action that bridges the gap between immediate danger and professional intervention. By providing clear, specific information, you empower responders to act swiftly and effectively, mitigating risks to life, property, and the environment. In the face of such emergencies, this step isn’t just recommended—it’s indispensable.

Keep Distance: Stay at least 50 feet away to avoid toxic fumes and explosions
Electric vehicle fires present unique dangers compared to their gasoline counterparts. Lithium-ion batteries, the powerhouse of EVs, can release toxic gases like hydrogen fluoride and phosphorus pentoxide when ignited. These fumes are not only harmful to inhale but can also be explosive under certain conditions. Standing too close during an EV fire exposes you to these hazards, making maintaining a safe distance paramount.
A minimum distance of 50 feet is recommended as a safety buffer. This distance significantly reduces the risk of inhaling toxic fumes and provides a safer zone in case of an explosion. Remember, these fumes are heavier than air and tend to accumulate close to the ground, so avoid crouching or lying down near the burning vehicle.
The 50-foot rule isn't arbitrary. It's based on the potential reach of thermal radiation and the blast radius of a battery explosion. While the chances of an explosion are relatively low, the consequences can be severe. A safe distance allows emergency responders to work effectively without putting bystanders at risk.
Imagine a scenario where an EV catches fire in a parking garage. The confined space amplifies the danger of fumes and potential explosions. In such cases, the 50-foot rule becomes even more critical, ensuring the safety of both bystanders and emergency personnel.
Don't be a hero. If you witness an EV fire, prioritize your safety. Move to a safe distance, call emergency services immediately, and warn others to stay away. Remember, your well-being is paramount. Let the professionals handle the situation with the necessary training and equipment.

Do Not Open Hood: Avoid opening the hood; let firefighters handle the lithium-ion battery fire
Electric vehicle fires, particularly those involving lithium-ion batteries, present unique challenges compared to traditional gasoline-powered cars. One critical rule stands out: do not open the hood. This instinctive action, often the first response in a conventional car fire, can exacerbate the situation in an electric vehicle (EV). Lithium-ion batteries, when exposed to air or water, can reignite or release toxic gases, making containment and suppression more difficult. Firefighters are trained to handle these specific risks, using specialized equipment like thermal imaging cameras and dry chemical extinguishers to manage the fire safely.
Opening the hood of a burning EV is not just ineffective—it’s dangerous. Lithium-ion battery fires burn at extremely high temperatures and can produce volatile off-gases. Lifting the hood introduces oxygen, potentially intensifying the fire or causing an explosion. Additionally, the battery pack is often located in the underbody or near the front of the vehicle, meaning the fire may not even be accessible through the hood. Instead, focus on evacuating all occupants, moving to a safe distance (at least 10–15 meters), and calling emergency services immediately. Provide responders with the vehicle’s make, model, and year to help them prepare for the specific battery configuration.
Firefighters approach EV fires differently than gasoline fires. They prioritize cooling the battery pack to prevent thermal runaway, a chain reaction where cells overheat and ignite one another. This process can take hours, as the battery must be cooled to a safe temperature. Opening the hood interferes with this strategy, as it disrupts the controlled environment firefighters create to manage the blaze. For instance, Tesla’s emergency response guide explicitly warns against puncturing, cutting, or applying water directly to the battery pack, emphasizing the need for professional intervention.
Practical tips for bystanders include avoiding direct contact with the vehicle, as high-voltage systems pose electrocution risks even when the car is off. If possible, park the EV in an open area away from buildings, flammable materials, and other vehicles to minimize collateral damage. While waiting for firefighters, monitor the vehicle from a safe distance for signs of worsening conditions, such as smoke color changes or unusual noises. Remember, the goal is to contain the fire, not to extinguish it prematurely, as lithium-ion fires can reignite if not properly managed.
In summary, the mantra do not open the hood is a critical safety measure in EV fires. Letting firefighters handle the situation ensures the fire is managed with the appropriate tools and techniques, reducing risks to both bystanders and responders. Understanding these differences between EV and gasoline fires can save lives and prevent further damage, making it essential knowledge for EV owners and the general public alike.

Use Class D Extinguisher: Only trained professionals should use a Class D extinguisher for battery fires
Electric vehicle (EV) battery fires present unique challenges due to their chemical composition and energy density. Unlike traditional gasoline fires, these blazes involve lithium-ion batteries, which require specialized suppression methods. Among the tools available, the Class D fire extinguisher stands out as the most effective—but its use is not for the untrained. Designed specifically for combustible metal fires, Class D extinguishers contain dry powder agents like sodium chloride or graphite, which smother the fire by separating the fuel from oxygen and cooling the burning metal. However, their application demands precision and knowledge to avoid exacerbating the situation.
Using a Class D extinguisher on an EV battery fire is a multi-step process that requires careful execution. First, the operator must maintain a safe distance, typically 10 to 15 feet, to avoid exposure to toxic fumes or explosive reactions. Second, the powder must be applied gently but thoroughly to cover the entire battery surface, ensuring no exposed areas remain. Overapplication or improper technique can lead to the powder becoming airborne, reducing its effectiveness and creating a respiratory hazard. These risks underscore why only trained professionals, such as firefighters or industrial safety experts, should handle Class D extinguishers.
The dangers of misusing a Class D extinguisher cannot be overstated. For instance, applying the powder too forcefully can scatter burning metal particles, potentially igniting nearby materials or causing secondary fires. Additionally, the extinguisher’s powder can damage surrounding electronics or infrastructure, compounding the financial and safety consequences. In one notable case, an untrained individual attempted to use a Class D extinguisher on a garage EV fire, only to spread the blaze further due to improper technique. This example highlights the critical need for expertise in handling such equipment.
While Class D extinguishers are essential for battery fires, their use is just one component of a broader response strategy. Trained professionals also assess the fire’s progression, monitor thermal runaway risks, and coordinate with emergency services to ensure comprehensive containment. For bystanders or EV owners, the priority should be evacuating the area, calling emergency services, and avoiding any attempts to extinguish the fire themselves. Understanding these distinctions ensures that Class D extinguishers are deployed effectively, minimizing harm and maximizing safety in high-stakes scenarios.
