* Static Electricity: Cars generate static electricity while driving, which can build up in the fuel tank. Turning off the engine eliminates this charge, reducing the risk of an ignition source during fueling.
* Fuel Vapor Ignition: Fuel vapors are flammable, and a running engine can create sparks or heat that could ignite them. This is especially dangerous in enclosed spaces like gas station canopies.
* Engine Damage: Fuel vapors can be sucked into the engine, potentially damaging it if the engine is running during refueling.
* Environmental Hazards: Fuel spills are more likely when an engine is running, which can pollute the environment.
The risk of fire or explosion is the most significant reason to turn off the engine during refueling.
It's a simple, essential safety practice that every driver should follow.
