Electric cable unwind

Hi to all, could I just bring up the point about fire hazards on site regarding the unwinding of your electric cable.

If you have to park a certain distance from each caravan for fire regs then would it be a good idea for all wardens on site to tell you when you arrive that electric cable must be fully unwound as this is a fire hazard.

My friend was on a site recently when a caravan next to them had a fire which started at an unwound cable, the caravan was destroyed as was the awning and the car.

This surely has got to be addressed by the wardens on site as a lot don't seem to unwind it, they seem to think well it wont/never happened to me, but you should never say never.
