Fire safety for evs: learn how to put out an electric car fire

Electric vehicles (EVs) have gained immense popularity in recent years, but concerns about their potential fire hazards have also emerged. While EV fires are rare, they can be more challenging to extinguish than traditional gasoline-powered vehicle fires. This blog post provides a comprehensive guide on how to put out an electric car fire safely and effectively.

Understanding Electric Car Fire Hazards

EVs have unique fire hazards due to their high-voltage electrical systems and lithium-ion batteries. These components can generate intense heat and produce toxic fumes when ignited. Unlike gasoline fires, EV fires can be difficult to control and may reignite after being extinguished.

Safety Precautions

Before attempting to put out an electric car fire, it is crucial to take the following safety precautions:

• Stay away from the vehicle: Do not approach the burning car directly.
• Call emergency services: Immediately contact fire and rescue personnel.
• Evacuate the area: Move away from the vehicle and ensure the safety of bystanders.
• Wear protective gear: If possible, wear protective gloves and a face mask to avoid exposure to toxic fumes.

Extinguishing Techniques

1. Water Extinguisher:

• Use a Class D water extinguisher specifically designed for electrical fires.
• Spray water directly at the base of the fire, avoiding the electrical components.
• Continue spraying until the fire is extinguished and the area is cool to the touch.

2. Thermal Imaging Camera:

• Use a thermal imaging camera to locate hidden hotspots within the battery pack.
• Direct water or other extinguishing agents to these hotspots.

3. Foam Extinguisher:

• Apply a Class B foam extinguisher to the burning battery pack.
• The foam will create a barrier that smothers the fire and prevents oxygen from reaching it.

4. Baking Soda:

• Sprinkle baking soda over the burning battery pack.
• Baking soda releases carbon dioxide, which acts as a fire suppressant.

5. Sand or Dirt:

• If other extinguishing agents are not available, use sand or dirt to smother the fire.
• Cover the battery pack completely and avoid disturbing it.

Battery Cooling

Once the fire has been extinguished, it is essential to cool the battery pack to prevent it from reigniting.

• Submerge in Water: If possible, submerge the battery pack in a large body of water.
• Use Dry Ice: Place dry ice around the battery pack to absorb heat and prevent it from overheating.
• Monitor Temperature: Use a temperature probe to monitor the battery pack’s temperature and ensure it remains below 100 degrees Fahrenheit.

Fire Suppression Systems

Some electric cars are equipped with built-in fire suppression systems that automatically activate in the event of a fire. These systems can use water, foam, or other extinguishing agents to put out the fire quickly.

Training and Education

It is essential for firefighters and emergency responders to receive specialized training on how to handle electric car fires effectively. This training should include:

• Understanding EV fire hazards
• Extinguishing techniques
• Battery cooling methods
• Safety precautions

Takeaways: Fire Safety for Electric Vehicles

While electric car fires are rare, it is crucial to be prepared and know how to respond appropriately. By following the safety precautions and extinguishing techniques outlined in this guide, you can help minimize the risks associated with EV fires and ensure the safety of yourself and others.

Questions We Hear a Lot

1. What is the best way to extinguish an electric car fire?

Use a Class D water extinguisher or a thermal imaging camera to locate hotspots and direct extinguishing agents accordingly.

2. Can I use a garden hose to put out an electric car fire?

No. Garden hoses do not provide sufficient water pressure or coverage to extinguish an EV fire effectively.

3. Is it safe to touch an electric car that is on fire?

No. Stay away from the vehicle and do not touch any exposed electrical components.

4. What should I do if my electric car catches fire while I am driving?

Pull over to a safe location, put the vehicle in park, and evacuate immediately. Call emergency services and follow the safety precautions outlined in this guide.

5. How can I prevent electric car fires?

Regularly maintain your vehicle, avoid overcharging the battery, and park in a cool, well-ventilated area.
