Is it possible to reach an A340's fuselage from the ground? There is this ATC recording where an A340 pilot requests to leave the aircraft and close the fuel panel on the bottom of the fuselage, while the aircraft is on a taxiway (the request is made at 2:50). Now, here is a picture to show how to get in and out of an A340 without deploying the emergency slides and causing even more issues:

However, the picture also makes it look like it not actually possible for anyone to reach the fuselage from the ground. Is that actually the case? And if so, how would the pilot actually reach the fuselage and close the fuel panel?
Yes, the refuel/defuel service panel can be reached from a person standing on the ground.

From the Airbus A340-200/-300 Aircraft Characteristics - Airport and Maintenance Planning document, the height of the panel in question is just under 2 meters from the ground:



The panel is located on the lower area of the wing/body interface fairing as seen here (item 13):
