My aunt sent me this regarding the use of a cell phone while fueling up:

In the first case, the phone was placed on the car's trunk lid during fueling; it rang and the ensuing fire destroyed the car and the gasoline pump.

In the second, an individual suffered severe burns to their face when fumes ignited as they answered a call while refueling their car!

And in the third, an individual suffered burns to the thigh and groin as fumes ignited when the phone, which was in their pocket, rang while they were fueling their car.
