Grounding/bonding when refueling

[chewing4gum]

The regulations on refueling state:

"Vehicles and containers used to refuel and defuel aircraft must be earthed and also conductively connected to the aircraft."

Apart from sparking during refueling, what other dangers exist if the earthing or connection fails?
I read on another website that one only grounds his aircraft but does not connect. Apparently everything went well?

The danger is inflammation when refueling?

So an anonymous person who may not be doing things correctly has not had something go wrong yet. The internet.

I think that the topic has been well covered in this discussion.

"Vehicles and containers used to refuel and defuel aircraft must be earthed and also conductively connected to the aircraft."

That sounds like good regulation wording, do it that way.....
