Electric vehicles (EVs) and lithium-ion batteries indeed present unique challenges and considerations for emergency preparedness and response, particularly in the context of fire incidents. Here’s a summarised overview of the key points and recommendations:

FIRE RISKS

• EVs can catch fire due to battery thermal runaway, typically after a severe collision or battery malfunction.
• Firefighters face challenges due to the need for specialised techniques and water-resistant extinguishing agents.
• EV fires can result in water pollution as large quantities of water are used to cool batteries, potentially contaminating nearby water sources.

PREVENTION & SAFETY MEASURES:

• Parking in designated spots away from exits is crucial for rapid emergency response and safe evacuation.
• New EVs may have hose connections for firefighters to introduce water to cool down the battery compartment.

FIRE SERVICE RESPONSE:

• Fire services evaluate EV fires, protect exposures, and may let the fire burn itself out if no further risks or exposures exist.
• In a car park scenario, asset protection and stopping the spread are priorities.

EXTINGUISHING MEASURES:

• Occupants are generally discouraged from fighting the fire due to safety concerns.
• Any extinguishing agent must be applied directly to the battery pack to slow down the burn.
• Emergency Services consider the fire out when the battery temperature is 30°C or less for at least 60 minutes.

CHALLENGES FOR FIREFIGHTERS:

• Lithium-ion battery failures pose significant risks, including toxic smoke, rapid fire spread, and a fire duration of over 4 hours.
• Sufficient ventilation and ongoing water cooling are crucial during battery fire incidents.

Overall, these measures aim to enhance safety, response efficiency, and minimise environmental impact in the event of EV-related incidents.
