When refueling a bus with passengers, important safety protocols include using a static chain, keeping windows closed, and using the correct fuel grade.
Vehicles carrying riders must never be fueled without a static chain present. This is crucial to prevent static electricity discharge, which could lead to a fire or explosion.
In a scenario where riders are aboard, ensuring all windows are closed during refueling is essential. This helps maintain safety by preventing fumes from entering the passenger area.
Using a fuel grade other than what is recommended can lead to engine damage and performance issues, especially in modern vehicles that are designed to operate efficiently with specific fuel types.
