The new CAP748 states that no PED's ( Portable Electronic Devices ) are to be used with in a refuelling zone.
This includes all electronic equipment but as a refueller I know that flight crews, even though they are aware of refuelling, still transmit their radios to gain clearence or weather before departure ...
I have been a refueller for quite a few years now and dont really see that a 3 volt battery from a cell phone is going to ignite fumes when there is a very hot exhaust pipe from the refuelling vehicle with in the refuelling zone !
All contradicts really and I think all is trying to be on the safe side !
I had a conversation about using PED's with in this situation with one of the big fuel companies, no names, but he too said its all the govening bodies being too over cautious !
