What should be done with a high-voltage electric vehicle fire before any firefighting efforts?

In a high-voltage electric vehicle fire, the most critical initial step is to isolate the vehicle from other structures and ensure a safe perimeter is established. This is essential because high-voltage fires can cause unexpected explosions or release toxic gases, which could jeopardize the safety of firefighters and those in the vicinity. By creating a safe distance, it minimizes the risk to bystanders and prevents the fire from spreading to adjacent buildings or vehicles.

Isolating the area also allows for a clear assessment of the situation. Firefighters can then determine the necessary measures for containment and extinguishment without additional hazards that could complicate their efforts. While other options may seem potentially viable, addressing the immediate safety concerns takes priority, making isolation the most prudent initial action in this scenario.
