What Should Not Be Used to Extinguish a Vehicle Fuel Fire?

[JamesLee]

When a vehicle fuel fire occurs, water should not be used for extinguishing. Below are relevant details about fuel fires:1. Reason: Water should not be used to extinguish a vehicle fuel fire because fuel is lighter than water. When water comes into contact with fuel, it fails to cover the fuel and instead carries it, spreading the fire. Carbon dioxide fire extinguishers are also not suitable for use, as they are not effective in non-enclosed spaces.2. Precautions: In the event of an engine fire, the driver should promptly stop the vehicle, allow passengers to exit by opening the doors, then cut off the power supply, retrieve the onboard fire extinguisher, and aim it directly at the base of the flames to extinguish the fire.

Last year, while driving, I saw a car with smoke coming from the hood and fuel on fire. Someone quickly threw water on it, causing the flames to suddenly flare up and nearly burn people. Never use water on a fuel fire because water is heavier than oil and will sink to the bottom, allowing the oil to float up and continue burning. The heated water produces steam, which can cause the oil to splatter and spread the fire. I later learned the correct approach is to use a dry powder fire extinguisher or sand to smother the fire and cut off its oxygen supply. It's a good practice to keep a fire extinguisher in your car. If a fuel fire occurs, stop the car immediately and move to a safe distance—safety first. Remembering these tips can save lives. After that scary experience, I developed the habit of regularly checking my fire extinguisher.

From a common-sense perspective, using water to extinguish a fuel fire is a serious mistake—it's like adding fuel to the fire and worsening the situation. Oil and water don't mix, and pouring water onto the fuel surface only generates more steam and flame jets, which can easily trigger explosions and spread the fire. The correct approach is to smother the flames with a fire blanket or foam extinguisher, while also promptly calling for help and evacuating. I recommend keeping some dry powder extinguishers in your garage as a backup instead of relying on water in emergencies. These small details in daily driving can prevent major accidents. Safety is no joke—preventive measures are far more important than last-minute fixes.

Using water on a gasoline fire is ineffective because it causes the fuel to bubble and splatter, worsening the fire. From experience, I've seen people get burned when they used water—switching to a foam extinguisher or covering with sand works much better. It's advisable to keep a portable fire extinguisher in your car. In case of fire, stop immediately and call the firefighters. Staying alert can protect you.
