Safety Precautions: Before beginning the petrol filling process, petrol station attendants or customers must adhere to safety precautions. This includes turning off the vehicle engine, avoiding smoking or using electronic devices near the petrol pump, and ensuring that the vehicle is parked in a designated refueling area. Payment: If the petrol station operates on a self-service basis, customers may need to make payment first before dispensing petrol. This can be done at the petrol station kiosk or through electronic payment methods such as credit/debit cards or mobile payment apps. In full-service stations, attendants may handle payment transactions. Selecting the Pump: Customers select the appropriate petrol pump based on their vehicle's fuel type (e.g., petrol, diesel) and the desired fuel grade (e.g., regular, premium). Petrol pumps are typically labeled with the type of fuel and the corresponding pump number. Dispensing Petrol: After selecting the pump, customers or attendants lift the nozzle from the pump and insert it into the vehicle's fuel tank opening. The nozzle may have safety features such as an automatic shut-off mechanism that stops dispensing petrol when the tank is full. Monitoring and Controlling Flow: While dispensing petrol, customers or attendants monitor the flow rate and volume of petrol being pumped into the vehicle's fuel tank. They may adjust the flow rate or nozzle position to control the filling process and prevent spills or overflows. Filling to Capacity: Customers or attendants fill the vehicle's fuel tank to the desired level or until the automatic shut-off mechanism activates, indicating that the tank is full. It's important not to overfill the tank to avoid spillage or fuel wastage. Replacing the Nozzle and Closing the Fuel Cap: Once the tank is filled, customers or attendants replace the nozzle back onto the pump and securely close the vehicle's fuel cap. This helps prevent fuel evaporation, contamination, and unauthorized access to the fuel tank. Receipt and Confirmation: Customers may request a receipt from the petrol station kiosk or terminal to confirm the transaction and keep a record of the fuel purchase. The receipt typically includes details such as the amount of petrol dispensed, the total cost, and the date/time of the transaction. Safety Checks and Departure: Before leaving the petrol station, customers or attendants perform safety checks such as ensuring that the fuel cap is securely closed, the vehicle is in good working condition, and there are no signs of fuel leakage or spillage.
