How can you ensure proper grounding of fueling equipment?

1 Check the ground wire

The first step is to check the ground wire that connects the fueling equipment to the ground rod or the hydrant system. The ground wire should be in good condition, free of cracks, corrosion, or damage. It should also be securely attached to the ground rod or the hydrant system with a suitable clamp. If the ground wire is faulty, replace it or use another fueling equipment.

2 Check the bonding cable

The second step is to check the bonding cable that connects the fueling equipment to the aircraft. The bonding cable should also be in good condition, free of cracks, corrosion, or damage. It should also be securely attached to the fueling equipment and the aircraft with suitable clips. The clips should make direct contact with the metal surfaces of the fueling equipment and the aircraft, avoiding any paint, dirt, or insulation. If the bonding cable is faulty, replace it or use another fueling equipment.

3 Check the continuity

The third step is to check the continuity of the grounding and bonding circuit. This means verifying that there is no resistance or break in the electrical connection between the fueling equipment, the aircraft, and the ground. You can use a continuity tester or an ohmmeter to measure the resistance of the circuit. The resistance should be less than 10 ohms, or as specified by the manufacturer or the airport authority. If the resistance is too high, check for loose or dirty connections, or use another fueling equipment.

4 Check the grounding indicator

The fourth step is to check the grounding indicator on the fueling equipment. The grounding indicator is a device that shows whether the fueling equipment is properly grounded and bonded. It may be a light, a gauge, or a meter that indicates the status of the grounding and bonding circuit. The grounding indicator should show a green or a positive sign when the fueling equipment is properly grounded and bonded. If the grounding indicator shows a red or a negative sign, or does not work at all, do not use the fueling equipment.

5 Check the weather conditions

The fifth step is to check the weather conditions before and during refueling. Weather conditions such as low humidity, high winds, or thunderstorms can increase the risk of static buildup and discharge. You should avoid refueling when these conditions are present, or take extra precautions such as wetting the ground around the fueling equipment, using anti-static additives in the fuel, or increasing the grounding and bonding time.

6 Check the fueling procedures

The sixth step is to check the fueling procedures and follow them strictly. Fueling procedures are the guidelines and rules that govern the safe and efficient refueling of aircraft. They may vary depending on the type of aircraft, fuel, and fueling equipment. You should always consult the fueling procedures manual, the aircraft manual, or the airport authority before refueling. You should also follow the best practices such as wearing protective clothing and equipment, avoiding sources of ignition, and reporting any incidents or anomalies.
