Disaster Response Faces New Hazards Thanks to EVs

"disaster" word definition in a dictionary.

Electric vehicles are complicating wildfire response efforts in Los Angeles, posing new challenges for firefighters and cleanup crews.

Quick Takes

  • Electric vehicle batteries pose unique fire risks, requiring specialized firefighting techniques.
  • EV fires can burn longer and reignite, demanding excessive water usage for extinguishment.
  • Hazardous materials from burnt EVs are delaying residents’ return to affected areas.
  • California’s high EV adoption rate intensifies the challenges faced during wildfire responses.

EV Batteries: A New Frontier in Firefighting

As wildfires ravage Los Angeles, firefighters are grappling with an unexpected adversary: electric vehicles. The lithium-ion batteries powering these eco-friendly cars are presenting formidable challenges to fire response teams. Unlike conventional vehicle fires, EV blazes demand unique approaches and resources, significantly complicating standard firefighting procedures.

Robert Rezende, a firefighting expert, explains the complexities: “As the batteries start to burn, they actually release flammable gases like hydrogen and carbon dioxide, and then they also release their own oxygen, and so smothering the fire doesn’t really work in these situations. Putting a bunch of water on them doesn’t really work in these situations.”

Prolonged Burning and Reignition Risks

One of the most concerning aspects of EV fires is their tendency to burn longer than gasoline-powered vehicles. Rezende further notes, “So the battery just kind of has to run its course, and its chemistry needs to be consumed before it will stop being on fire.” This prolonged burning not only ties up firefighting resources but also increases the risk of fire spread in already volatile wildfire conditions.

Adding to the complexity, EV batteries have a propensity for reignition, even after appearing extinguished. This phenomenon necessitates extended monitoring periods and can require thousands of gallons of water to fully extinguish a single vehicle. Such water demands strain resources in drought-prone California, where water conservation is crucial.

Environmental and Health Concerns

The aftermath of EV fires in wildfire zones presents significant environmental and health hazards. Burnt-out electric vehicles, along with hybrid cars and home battery storage systems, contribute to a toxic mix of materials requiring specialized removal. These hazardous remnants not only pose immediate risks but also delay the return of fire victims to their properties.

California Governor Gavin Newsom acknowledged these emerging challenges: “While the state has extensive experience with clearing cars with combustion engines, cleanup teams are still adapting to newer technologies like Tesla and other lithium-ion batteries, which can pose distinct risks when exposed to high heat from fires”

Adapting Response Strategies

In response to these challenges, automakers and first responders are developing new strategies. Tesla, for instance, has created training videos for emergency personnel dealing with EV fires. However, the lack of standardized procedures for handling combusted battery packs continues to complicate EV disposal in fire-affected areas.

The Environmental Protection Agency (EPA) is stepping in to assist with battery debris removal, drawing on experience from previous disasters like the 2023 Maui Fire. During that cleanup, the EPA removed over 30 tons of lithium batteries from 94 electric and hybrid vehicles, highlighting the scale of the issue.

Implications for EV Adoption

These wildfire-related challenges are raising concerns among EV owners about evacuation readiness and charging infrastructure reliability during emergencies. Some owners report limited evacuation routes and longer lines at charging stations compared to gasoline stations during crisis situations.

These concerns are reflected in broader trends. A McKinsey & Co. survey found that 46% of U.S. EV owners and 29% globally are considering switching back to internal combustion engine vehicles, citing inadequate charging infrastructure and concerns about long-distance travel capabilities.

Looking Ahead

As California leads the nation in EV adoption, surpassing 2 million electric, plug-in hybrid, and hydrogen-powered vehicles sold, the state faces a critical juncture. Balancing environmental goals with emergency preparedness will require innovative solutions and collaborative efforts between automakers, emergency services, and policymakers to ensure public safety in an increasingly electrified automotive landscape.
