What is the primary hazard associated with electric vehicles during a fire incident?

The primary hazard associated with electric vehicles during a fire incident is the high-voltage electrocution risk. Electric vehicles are equipped with large battery packs that operate at high voltages, often exceeding 400 volts. When these vehicles catch fire, the potential for electrical hazards increases significantly, posing a serious risk to first responders and bystanders.

This high-voltage system can become compromised during a fire, which might expose live electrical components. Responders may encounter downed wires, and they could inadvertently come in contact with these dangerous voltages, leading to severe electric shock or electrocution if proper safety protocols are not followed.

In addition to the electrocution risk, the way electric vehicle batteries burn can produce hazardous materials, and the batteries themselves may vent or explode under extreme heat, creating further dangers. However, when specifically considering the primary hazard, high-voltage electrocution risk stands out due to the immediate danger it presents in a fire-fighting scenario.
