What Happens to Electric Vehicles That Catch Fire
What happens to electric vehicles that catch fire during wildfires is a critical concern as the adoption of sustainable transportation grows. Although electric vehicle (EV) fires are infrequent, they pose distinct challenges due to the characteristics of lithium-ion batteries. These fires can emit over 100 toxic chemicals, including heavy metals and gases like carbon monoxide and hydrogen cyanide. Unlike conventional car fires, EV fires can be challenging and time-consuming to put out because of the potential for the batteries to reignite.
- Release of toxic chemicals such as heavy metals, carbon monoxide, hydrogen cyanide
- Difficult to extinguish due to the risk of reignition in lithium-ion batteries
- Prolonged exposure increases risks to firefighters and surrounding environment
I’m Ben Trapskin, and through my work at Yawnder, I am deeply involved in understanding the safety aspects of EV fires. By collaborating with experts and conducting extensive research on what happens to electric vehicles that catch fire during wildfires, I’ve developed insights to enhance awareness and protective strategies.

What Happens to Electric Vehicles That Catch Fire During Wildfires
When electric vehicles catch fire during wildfires, the resulting chemical reactions can pose serious risks. The lithium-ion batteries in EVs are at the core of these dangers.
Chemical Reactions and Fire Risks
EV fires are not your typical vehicle fires. They are chemical fires that release a cocktail of over 100 toxic substances. These include heavy metals, carbon monoxide, and hydrogen cyanide. These chemicals are harmful to both the environment and human health.
-
Heavy metals: Released during the combustion of the battery, these can contaminate soil and water.
-
Carbon monoxide: A colorless, odorless gas that can be deadly if inhaled in large amounts.
-
Hydrogen cyanide: A highly toxic gas that can cause serious health issues upon exposure.
Challenges in Extinguishing EV Fires
Extinguishing an EV fire is a significant challenge. The batteries in these vehicles can reignite even after the flames appear to be out. This is due to the phenomenon known as thermal runaway, where heat from one cell spreads to others, causing a chain reaction.
Firefighters face prolonged exposure to toxic gases and extreme heat. This makes the situation dangerous and complex to manage. The prolonged firefighting required increases the risk of exposure to harmful substances for both the firefighters and the surrounding environment.
-
Reignition risk: Lithium-ion batteries can reignite hours or even days after the initial fire.
-
Prolonged exposure: Firefighters are at risk of inhaling toxic fumes, which can lead to long-term health issues.
Handling these fires requires specialized equipment and techniques, which will be discussed in the following sections.
Causes of EV Fires in Wildfire Scenarios
Electric vehicles can catch fire during wildfires for several reasons. Understanding these causes is crucial for preventing and managing such incidents effectively.
Saltwater Exposure
While saltwater exposure isn’t a common concern in wildfires, it can be a risk in areas prone to coastal flooding. When lithium-ion batteries in EVs are submerged in saltwater, it can lead to short-circuiting. Saltwater acts as a conductor, allowing electricity to flow between the battery’s positive and negative terminals, generating heat. This can result in thermal runaway, a dangerous situation where the battery overheats and potentially ignites.
Short Circuit
Short circuits are a significant cause of EV fires, especially during wildfires. A short circuit occurs when the electrical flow bypasses its intended path, often due to damage from heat or debris. This can lead to a rapid discharge of electricity, causing the battery to overheat and catch fire. In wildfire scenarios, the intense heat and debris can damage the battery casing, increasing the risk of a short circuit.
Battery Overheating
Wildfires create extreme heat conditions, which can lead to battery overheating in electric vehicles. The high temperatures can compromise the battery’s integrity, causing it to overheat and ignite. Once a battery begins to overheat, it can trigger a thermal runaway, where the heat spreads from one cell to another, leading to a self-sustaining fire. This makes it challenging to extinguish and control the fire.
In summary, while saltwater exposure is a rare cause in wildfires, short circuits and battery overheating are more common triggers. These factors highlight the importance of understanding and mitigating the risks associated with electric vehicles in wildfire situations. The next section will explore the safety measures and firefighting techniques used to address these challenges.
Safety Measures and Firefighting Techniques
When an electric vehicle catches fire during a wildfire, specialized equipment and techniques are crucial to manage the situation effectively.
Equipment Used by Firefighters
Firefighters face unique challenges when dealing with EV fires. These fires can be intense and difficult to extinguish due to the nature of lithium-ion batteries. Clark County Fire Department has been proactive in addressing these challenges by equipping their teams with specialized tools.
EV Fire Blanket: This is a large, heavy-duty blanket designed to smother the flames and contain toxic smoke. The blanket is made from fire-resistant materials and can cover the entire vehicle, helping to isolate the fire and prevent it from spreading. Deploying it requires a team effort due to its size and weight.
Turtle Nozzle: This innovative tool is used to cool the battery from underneath the vehicle. It slides under the car and sprays water directly onto the battery pack, helping to lower its temperature and prevent thermal runaway. This method is crucial because EV batteries can generate their own oxygen, making traditional firefighting methods less effective.
Importance of Professional Intervention
In the event of an EV fire, evacuate the area immediately and call 911. The fumes from an EV fire can be highly toxic, containing substances like carbon monoxide and hydrogen cyanide.
Professional response is essential because firefighters are trained to handle the specific hazards associated with electric vehicles. They have the equipment and knowledge needed to manage these fires safely and effectively. Attempting to extinguish the fire yourself can be extremely dangerous due to the risk of toxic gas exposure and the difficulty in controlling the fire.
In summary, handling EV fires requires specialized tools and trained professionals. The use of an EV fire blanket and turtle nozzle are key techniques employed by firefighters to manage these challenging situations. Always prioritize safety by evacuating and contacting emergency services.
Frequently Asked Questions about EV Fires
How Toxic is an Electric Car Fire?
Electric car fires can release a cocktail of toxic chemicals. When a lithium-ion battery ignites, it emits dangerous gases like carbon monoxide, hydrogen cyanide, and heavy metals. These substances can pose serious health risks to anyone nearby, especially firefighters who are exposed during firefighting operations.
Firefighter exposure is a major concern because the prolonged effort to control EV fires increases their contact with these harmful chemicals. The Firefighter Cancer Initiative is studying these risks to develop protective measures for those on the front lines.
Can Firefighters Put Out Electric Car Fires?
Yes, but it’s complicated. Firefighting challenges with electric vehicles are significant due to the nature of lithium-ion batteries. These batteries can undergo a process called “thermal runaway,” where the fire generates its own oxygen, making it difficult to extinguish.
Firefighters use specialized equipment like the EV fire blanket and turtle nozzle to manage these fires. The blanket helps to smother the flames and contain toxic smoke, while the turtle nozzle cools the battery by spraying water directly onto it. These tools are essential for controlling the fire and preventing it from reigniting.
How Often Do Electric Cars Catch Fire?
Despite the headlines, electric vehicles (EVs) catch fire less frequently than gasoline-powered cars. According to the National Transportation Safety Board (NTSB), there are about 25 EV fires per 100,000 units sold, compared to 1,530 for gasoline vehicles. However, when EV fires do occur, they can be more challenging to extinguish.
In various regions, the number of EV fires has been rising, highlighting the growing need for effective safety measures as EV adoption increases. Understanding these statistics helps put the risk into perspective and underscores the importance of professional intervention when EV fires occur.
