What must be done before refueling?
Preventive and Efficient Driving – Observation and Fuel Saving
Explanation
Before refueling, it is important to **turn off the engine, lights, electrical devices, and mobile phones**. This is due to several safety reasons:
- **Turn off the engine**: Prevents the vehicle from being operational while refueling, which can be dangerous due to the possibility of sparks or heat that could ignite fuel vapors.
- **Turn off the lights and electrical devices**: Lights and other electrical devices, such as the radio, can generate sparks. These sparks, although small, are sufficient to ignite the flammable vapors of the fuel.
- **Turn off mobile phones**: Mobile phones can also be a source of sparks or electrical interference. Although the risk is low, it is an additional precautionary measure to avoid any possibility of ignition.
These actions are essential to prevent accidents and ensure safety during the refueling process.
