Electric vehicles (EVs) are increasingly common, but they have also been the subject of scrutiny due to fire hazards. While EV fires are less common than those involving traditional gas-powered vehicles, they are more challenging to extinguish. This is because EV batteries, particularly lithium-ion batteries, take a long time to cool and can reignite after being put out. Additionally, over a hundred toxic chemicals are released during an EV fire, posing health and environmental risks. Despite these concerns, studies show that the risk of an EV fire is very low, with Australia's EV FireSafe reporting a risk of 0.0012%. As EVs become more prevalent, addressing fire safety and understanding the associated risks will be crucial.

Electric vehicles are less likely to catch fire than traditional gas-powered vehicles
Electric vehicles (EVs) are less likely to catch fire than traditional gas-powered vehicles. This is because EVs do not have an engine or the accompanying mechanical systems, which are often the cause of vehicle fires. According to the National Fire Protection Association (NFPA), mechanical failure or malfunction is the leading cause of vehicle fires, accounting for 45% of all such incidents. In contrast, electrical problems, which are more common in EVs, account for only 23% of vehicle fires.
The absence of gasoline, hot exhaust, and controlled explosions in EVs also significantly reduces the potential sources of ignition. Data from the National Transportation Safety Board reinforces this, showing that out of every 100,000 vehicles sold, approximately 25 EVs were involved in fires, compared to 1,530 gasoline-powered vehicles and 3,475 hybrids. This trend is consistent across other countries, including Norway, Sweden, and Australia.
While it is true that EV fires can be challenging to extinguish due to the nature of lithium-ion batteries, the overall risk of an EV catching fire is significantly lower than that of a traditional gas-powered vehicle. The NFPA report also cites worn-out parts and deferred maintenance as factors that increase the fire danger for older cars, which are more likely to catch fire.
It is worth noting that the media coverage of EV fires may give a skewed perception of their frequency. As EVs are still relatively new, and their fires can be challenging to extinguish, they tend to receive more attention in the news. However, the actual data shows that EV fires are quite rare, with Australia's EV FireSafe study estimating the risk of an electric car battery catching fire at 0.0012%, compared to 0.1% for internal combustion engine vehicles.
In summary, while EV fires can be dangerous and difficult to put out, they are much less likely to occur than fires in traditional gas-powered vehicles. The absence of mechanical systems, gasoline, and other combustion sources significantly reduces the risk of ignition in EVs. As such, consumers should not be deterred from purchasing an EV due to fire safety concerns.

Electric vehicle fires are difficult to extinguish
Electric vehicles (EVs) are less likely to catch fire than traditional gas-powered vehicles. However, electric vehicle fires are more difficult to extinguish. This is due to the nature of the lithium-ion batteries used in EVs, which can experience thermal runaway, a chemical process that is challenging to extinguish and has a higher likelihood of reignition after the fire is believed to be put out.
The difficulty in extinguishing EV fires lies in the unique characteristics of lithium-ion batteries. When these batteries are damaged, such as in a severe car crash, they can rupture and heat up rapidly through chemical reactions, leading to a fire. The chemical process in lithium-ion batteries, known as thermal runaway, can be challenging to control as it does not require oxygen to continue burning. As a result, EV fires can take a long time to cool down, creating an extended risk of reignition.
The National Fire Protection Association (NFPA) has acknowledged the challenges associated with EV fires and has published resources for first responders, including safety trainings and emergency response protocols. The NFPA also promotes electrical safety campaigns to raise awareness among consumers about electrical fire hazards. Additionally, organizations like the Firefighter Cancer Initiative are conducting multidisciplinary studies to understand the environmental and health consequences of EV fires, as more than 100 chemicals are released during these fires, including toxic substances such as heavy metals, carbon monoxide, and hydrogen cyanide.
The rarity of EV fires compared to gas-powered vehicle fires is important to note. Data from various countries, including the United States, Norway, Sweden, and Australia, consistently shows that EV fires are relatively uncommon. For example, the National Transportation Safety Board reported that EVs were involved in approximately 25 fires for every 100,000 sold, while gasoline-powered vehicles had a significantly higher rate of 1,530 fires per 100,000 sold. This disparity in fire involvement underscores the lower risk associated with EVs.
While EV fires are less common, the challenges in extinguishing them highlight the importance of ongoing research and training for first responders. Understanding the unique characteristics of EV fires and developing effective strategies to address them are crucial to ensuring the safety of both firefighters and the public.

Electric vehicle fires release over 100 harmful chemicals
Electric vehicles (EVs) are generally considered to be extremely safe. However, a common cause of electric vehicle fires is damage to the vehicle's lithium-ion battery pack, which can occur as a result of a serious crash or exposure to extreme heat. These fires can be challenging to extinguish and may take hours to control, increasing the risk of exposure to the over 100 toxic chemicals released.
During an electric vehicle fire, a range of harmful chemicals and gases are generated, including heavy metals, carbon monoxide, and hydrogen cyanide. These toxins pose a significant risk to both firefighters and the public. Firefighters must wear full PPE with respiratory equipment to protect themselves from the toxic gases released during an EV fire.
The challenge of extinguishing EV fires lies in the nature of lithium-ion batteries, which can experience thermal runaway, a chemical process that leads to a vicious cycle of increasing heat and accelerating chemical reactions. This can result in ignition or even explosion. Additionally, lithium-ion batteries take a long time to cool, creating an extended danger of reignition, even after the fire appears to be extinguished.
The rarity of EV fires is important to note. Data from the London Fire Brigade revealed that in 2019, they responded to 54 electric vehicle fires compared to 1,898 petrol and diesel fires. Similarly, in 2020, they dealt with 27 electric vehicle fires out of a total of 1,021 petrol and diesel fires. This data reinforces the notion that EV fires are relatively uncommon.
While the dangers of EV fires are real, they are not as frequent as fires in gas-powered vehicles. The media coverage of EV fires may create a perception of heightened risk, but it is important to remember that EVs are still relatively new, and their fires are less common and less likely to occur than those in traditional combustion engine cars.

Electric vehicle batteries take a long time to cool, creating a risk of reignition
Electric vehicles (EVs) are less likely to catch fire than traditional gas-powered vehicles. However, when they do, fires in electric vehicles can be challenging to extinguish. This is due to the nature of the lithium-ion batteries used in these vehicles, which take a long time to cool and can thus reignite even after the fire is believed to have been put out.
The difficulty in extinguishing electric vehicle fires lies in the unique characteristics of lithium-ion batteries. When these batteries are damaged, they can undergo thermal runaway, a chemical process that is challenging to stop because it does not require oxygen. This process can occur due to a serious crash that damages the battery pack or other factors that cause the batteries to overheat.
The time it takes for these batteries to cool creates a significant risk of reignition. As a result, firefighters may need to submerge the burning vehicle in a large container of water for an extended period, even weeks, to ensure the fire does not reignite. This method is more effective than spraying water on the fire, but it still uses a lot of water and requires careful handling to prevent toxic runoff.
The release of over 100 chemicals during an electric vehicle fire, including heavy metals, carbon monoxide, and hydrogen cyanide, poses a severe health hazard to firefighters and the public. The prolonged duration of these fires, often lasting hours, increases the exposure of firefighters and others in the vicinity to these toxic substances. Therefore, it is crucial to have proper safety measures and protocols in place to manage electric vehicle fires effectively and minimize the risks associated with them.
To address the challenges posed by electric vehicle fires, organizations are working to train fire departments on best practices and improve fire-suppressing techniques and chemicals. The National Fire Protection Association (NFPA), for example, has published resources for first responders, including safety trainings and emergency response materials provided by automobile manufacturers.

Electric vehicle fires receive more media coverage than gas-powered vehicle fires
Electric vehicles are less likely to catch fire than traditional gas-powered vehicles. However, electric vehicle fires receive more media coverage than gas-powered vehicle fires. This discrepancy in coverage can be attributed to several factors. Firstly, EVs are relatively new, and fires involving new technologies are often perceived as more newsworthy. Additionally, electric vehicle fires can be challenging to extinguish and may require specialized knowledge and equipment, which can make them more prominent in the news.
The rarity of electric vehicle fires contributes to their newsworthiness. According to the National Fire Protection Association (NFPA), mechanical failure or malfunction is the leading cause of vehicle fires, accounting for 45% of all incidents. In comparison, electrical problems, which are more common in EVs, account for only 23% of vehicle fires. The NFPA also notes that older cars are far more likely to catch fire, and the risk increases with the age of the vehicle. As most EVs are newer models, they are less likely to experience fire-related issues.
The difficulty in extinguishing electric vehicle fires is another factor that attracts media attention. The lithium-ion batteries used in EVs can experience thermal runaway, a chemical process that is challenging to extinguish and has a higher likelihood of reignition. This prolongs firefighter exposure to toxins and requires specialized training and procedures to address effectively. The release of over 100 chemicals during an electric vehicle fire, including heavy metals, carbon monoxide, and hydrogen cyanide, further complicates the situation and poses health risks to both firefighters and the public.
The media coverage of electric vehicle fires is also influenced by the visual nature of the incidents. Electric vehicle fires, particularly those involving lithium-ion batteries, can be spectacular and generate dramatic images and videos that are highly shareable on social media platforms. This visual aspect can contribute to the perception that EVs are more dangerous than traditional gas-powered vehicles.
While electric vehicle fires are indeed less common than gas-powered vehicle fires, the media coverage often fails to provide the full context. The headlines and social media posts that go viral may create a misleading impression of the actual fire risk associated with EVs. It is important for consumers to understand the facts and make informed decisions based on data rather than sensationalized news stories.
