Firefighters attempt to put out flames on an electric vehicle caught from floods by Hurricane Ian
Florida State Fire Marshal Jimmy Patronis has called for electric car companies to answer for electric vehicles that have burst into flames from the storm surge of Hurricane Ian.
The State Fire Marshall issued a letter to over 30 electric vehicle manufacturers, including Tesla, Rivian, Ford, GM and others, calling on the companies to “step-up, demonstrate leadership and partner with the State of Florida and local officials in this recovery.”
Patronis noted that the vehicles are a hazard to vehicle owners, fire teams and nearby Floridians. He chastised manufacturers for not building in safeguards against spontaneous combustion.
“The unfortunate reality is that there is a population of vehicles that could spontaneously combust, putting our first responders at risk, and the manufacturers are nowhere to be found. For as big a risk as this is to fire teams, for companies who have received an immense sum of subsidies from taxpayers, I would have hoped the reaction by manufacturers would have been more robust – especially as these EVs supposedly have a tremendous amount of technology and connectivity,” he wrote in the letter. “There could be a family who evacuated, whose home was left relatively intact from Ian, who may still lose everything because of an abandoned EV, left in their garage, that catches fire as a result of salty storm surge waters.”
Some Floridians have already discovered this the hard way. One house on hard-hit Sanibel Island was severely damaged after the Tesla in the garage of the home caught on fire from the storm, according to a retweet from Patronis.
Patronis fears that many more EVs are a fire risk in the wake of Hurricane Ian.
According to the National Highway Traffic Safety Administration, there have been multiple recalls for EV’s as once the lithium-ion batteries are damaged from saltwater, they become easily flammable and cause the vehicle to combust.
The NHTSA also stated that flooded electric cars should be at least 50 feet away from any structures, vehicles or anything else that can easily catch on fire.
Patronis’ entire letter can be read below:

Dear CEO Elon Musk:
As you are aware, nearly three weeks ago Hurricane Ian impacted Florida’s Southwest coast, inundating the area with salty storm surge waters. The Category 4 hurricane was so massive, storm surge reached 16 feet in certain areas and went as far inland as downtown Fort Myers. From my experience in traveling the state, there were a tremendous amount of Electronic Vehicles (EVs) in this part of Florida, and we now know for a fact that any EV that was submerged in saltwater is a fire risk.
As the National Highway Transportation Safety Administration (NHTSA) confirmed last week, “Test results specific to saltwater submersion show that salt bridges can form within the battery pack and provide a path for short circuit and self-heating. This can lead to fire ignition.” The federal agency also confirmed that, “Lithium-ion vehicle battery fires have been observed both rapidly igniting and igniting several weeks after battery damage occurred.” Further, I saw with my own eyes as North Collier Fire Rescue fought an EV fire that continuously reignited. It was surreal, and frankly scary, watching fire teams fight this EV fire, using tens-of-thousands of gallons of water to cool the batteries, and then again watching the EV reignite. I even found out later that the car reignited on the tow truck. Florida firefighters have been the tip of the spear in hurricane recovery operations, and more has to be done to help these heroes deal with the unique challenges of EV fires. The fumes from the fires are dangerous, fires reignite, and fire teams don’t have a lot of tools at their disposal in dealing with these lithium-ion vehicle battery fires.
The unfortunate reality is that there is a population of vehicles that could spontaneously combust, putting our first responders at risk, and the manufacturers are nowhere to be found. For as big a risk as this is to fire teams, for companies who have received an immense sum of subsidies from taxpayers, I would have hoped the reaction by manufacturers would have been more robust – especially as these EVs supposedly have a tremendous amount of technology and connectivity. There could be a family who evacuated, whose home was left relatively intact from Ian, who may still lose everything because of an abandoned EV, left in their garage, that catches fire as a result of salty storm surge waters. That’s a risk that requires more of a response from manufacturers than just telling customers to consult the owner’s manual.
Many of these families are trying to rebuild their lives following Ian, and manufacturers should really be doing more for families in their time of need. That’s just good corporate stewardship.
In this context, we need EV manufacturers to step-up, demonstrate leadership and partner with the State of Florida and local officials in this recovery to ensure that:
1. Outreach to EV owners by manufacturers takes place, alerting customers to the risks of EVs and fires from salty storm surge waters.
2. Identifying and safely relocating compromised EVs to appropriate spaces for monitoring.
3. Having an on-the-ground presence and offering assistance to customers and first responders in mitigating these risks.
Because each and every EV model is different, and because much of this information is not publicly available under the premise of trade secrets, we need more information that is specific to each and every EV model. As such, I am requesting the following information of your company:
1. Has your company conducted any analysis on the effects of saltwater intrusion on the lithium ion batteries in your vehicles and their risks associated with fires?
2. Over what period of time does a fire risk exist from a vehicle impacted by saltwater, or does the risk exist indefinitely? While NHTSA confirmed to our office that “fire ignition” can occur “several weeks” after exposure to saltwater, firefighters and other first responders need greater specificity to accurately assess, plan, and act on these risks.
3. Can you provide to the state information on the location of these EVs in the runup to impacts from Ian?
4. Can you provide a point of contact for your company that can be shared with emergency officials?
5. Are there any fire risks associated with chargers that were submerged in storm surge?
6. Do you have the ability to assess whether an EV, impacted by storm surge, is operational and currently being used?
7. To your knowledge, is there any fire suppression technology that has great success in ensuring fires do not reignite?
8. As much of the Central portion of Florida was flooded by heavy rains, is there any associated risks with submersion in freshwater?
9. Will you forego any attempts to limit information, under the premise of proprietary secrets, and agree to make the provided information to above questions publicly available as to facilitate greater coordination amongst industry experts as we work in real time to mitigate risks?
Please provide answers to my office for public distribution no later than October 24th. Again, the recovery in Southwest Florida is still ongoing. There are still families who have not gotten to their homes and families who are sifting through their belongings, making hard decisions. While this information is critical to mitigating further suffering, we really need to see more action by your company on a product that no one knows more about better than your engineers and your experts.
I look forward to your response.
Sincerely,
Jimmy Patronis
Chief Financial Officer
