And an ignition source. But close enough.
The crocodile clip falling off alone will not cause a fire.
True. But it can be the event that leads to providing an ignition source.
It is solely a matter of preventing fire during refueling or are there any other factors? Have I summarized this correctly?
Not only during refueling ops. Transfer of flammable fluids, various methods of checking storage containers levels, and even fuel pump filter changes can all lead to a static electricity ignition event. I couldn't find the PDF I was looking for but the one below provides a good overview on static electricity issues and flammable fluids and may answer your questions in a better format.
