Florida's fire marshal calls electric vehicles [ticking time bombs]
Florida's fire marshal, Jimmy Patronis, has warned that electric vehicles (EVs) are "ticking time bombs" due to the risk of battery fires when exposed to saltwater during hurricanes. This warning comes amid concerns about the impact of Hurricane Milton, a Category 3 storm that made landfall on Florida's central west coast.
In preparation for Hurricane Milton, Patronis cautioned residents and first responders about the heightened fire hazard posed by EVs, hybrid vehicles, and fuel cell products. The issue arises when lithium-ion batteries in these vehicles come into contact with saltwater, creating a dangerous situation. Florida officials have confirmed 48 lithium-ion battery fires related to Hurricane Helene, with 11 involving EVs.
The risk of battery fires in EVs after exposure to saltwater is well-documented. Similar incidents occurred during previous hurricanes, including Ian, Idalia, and Sandy. Federal safety agencies, such as the National Highway Traffic Safety Administration (NHTSA), have emphasized the danger of these batteries post-immersion, with fires potentially igniting hours or even weeks later. The NHTSA reported that Hurricane Ian in 2022 damaged between 3,000 and 5,000 EVs in Florida, with 36 catching fire.
To mitigate the risk, officials are urging EV owners to relocate their vehicles to higher ground and away from residences to minimize the potential for flood damage. Insurers, carmakers, and politicians have also issued warnings to EV owners, highlighting the potential for spontaneous combustion in flooded electric cars. Despite these concerns, it is important to note that outside of saltwater flooding, EVs are less likely to catch fire than gas-powered vehicles.
While the focus is currently on the potential dangers of EVs during hurricanes, they can also provide benefits during severe weather. Electric vehicles can offer essential communication lines and charging options that gas-powered vehicles cannot. As the frequency and intensity of hurricanes increase, Florida leaders are encouraged to embrace renewable energy sources and reduce subsidies for the fossil fuel industry.

Saltwater intrusion increases the chance of lithium-ion batteries catching fire
Florida has witnessed a rising trend of electric vehicles (EVs) catching fire, especially in the aftermath of hurricanes. Hurricane Milton, which made landfall as a Category 3 storm, brought this issue to the forefront, with officials warning of the fire hazards associated with lithium-ion batteries and saltwater intrusion.
The issue of saltwater intrusion in lithium-ion batteries is not limited to electric vehicles. It also affects other electronic devices such as scooters, hoverboards, and golf carts. The highly combustible nature of lithium-ion batteries when exposed to saltwater poses a significant risk to both property and human life.
The reason behind this lies in the chemical reaction that occurs when lithium-ion batteries come into contact with saltwater. This reaction can cause the battery to degrade and become extremely flammable, even hours or weeks after the initial exposure. As a result, EVs and electronic devices exposed to saltwater during floods or hurricanes can pose a fire risk long after the storm has passed.
To address this issue, officials and car manufacturers have issued warnings to EV owners, advising them to relocate their vehicles to higher ground and away from residences. In the event of saltwater exposure, it is recommended to keep the affected vehicle at least 50 feet away from any structures until a mechanic can inspect it. Additionally, insurance companies have cautioned their policyholders about the increased risk of EV fires after water damage, emphasizing the need for protected parking areas.

Electric vehicles can provide options and essential communication lines during severe weather
Electric vehicles (EVs) have been deemed a "ticking time bomb" by Florida's fire marshal, Jimmy Patronis, due to the risk of lithium-ion batteries exploding when exposed to saltwater during hurricanes. Despite this, electric vehicles can offer several advantages during severe weather events.
Firstly, electric vehicles are less likely to catch fire than gas-powered vehicles. Data from the U.S. National Transportation Safety Board indicates that for every 100,000 gas-powered vehicles sold, approximately 1,530 fires occur, compared to just 25 fires for every 100,000 EVs sold. This highlights that EVs are significantly less prone to fires, even without considering the additional risk of gas leaks associated with traditional cars.
Secondly, electric vehicles eliminate the need to queue for gasoline, which is a common occurrence before and after hurricanes. During Hurricane Helene, for instance, long lines formed at gas stations as the storm approached, and these lines persisted even after the hurricane had passed. With an EV, you can charge your vehicle at home or at designated charging stations, avoiding the hassle and potential danger of waiting in line for gasoline during severe weather.
Additionally, electric vehicles can serve as a source of backup power during power outages caused by hurricanes or other severe weather events. V2G (vehicle-to-grid) technology allows EVs to communicate with the electrical grid and provide power back to the grid when needed. This feature enhances resilience and can be crucial for maintaining essential functions and communication lines during power disruptions.
Furthermore, electric vehicles equipped with advanced driver-assistance systems (ADAS) can provide additional safety features during severe weather conditions. ADAS utilizes technologies such as cameras, radar, and sensors to enable features like collision avoidance, lane departure warning, and adaptive cruise control. These features can be invaluable for navigating through harsh weather conditions, improving visibility, and reducing the risk of accidents.
While the risk of lithium-ion battery fires in EVs exposed to saltwater is a legitimate concern, it's important to follow safety protocols and relocate EVs to higher ground or away from flood-prone areas. By taking the necessary precautions, the benefits of electric vehicles during severe weather, such as reduced fire risk, fuel accessibility, backup power, and advanced safety features, can be leveraged to enhance overall resilience and safety for Floridians.

The risk of EVs catching fire depends on how responders remove the car
Electric vehicles (EVs) are generally less likely to catch fire than conventional cars. However, in the wake of Hurricane Milton, Florida officials have warned of the heightened risk of EVs catching fire after being submerged in saltwater. This is due to the presence of lithium-ion batteries, which can experience thermal runaway, a chemical process that is challenging to extinguish and has a high likelihood of reignition.
Responders must be cautious when dealing with flooded EVs as the saltwater from storm surges can compromise the lithium-ion batteries, leading to fires that are difficult to suppress. The recommended course of action is to keep water on the battery to prevent reignition until the fuel burns out. Responders should also prioritize moving affected EVs away from residences and other structures to mitigate the risk of fire spreading to buildings.
The National Fire Protection Association (NFPA) has developed resources for first responders, including safety trainings and emergency response protocols, to address the unique challenges posed by EV fires. It is crucial for responders to be equipped with the knowledge and skills to handle EV fires effectively and minimize potential damage.
While the overall risk of EVs catching fire is relatively low compared to conventional cars, the impact of hurricanes and saltwater exposure has brought attention to this issue in Florida. Responders play a critical role in managing and mitigating the fire risk associated with flooded EVs, ensuring the safety of residents and their properties.
