I think that the practical possibility of a mobile phone causing an
explosion is somewhere on the region of zero

This sort of discussion always reminds me of a talk on risk I remember
from years back. "Are you willing to take a risk if the odds are 1000
to 1?" Most people would say "yes." "OK here is a jar with 1000
smarties in it, plus one that has cyanide in it, would you like to take
one?" answer was normally "no"

With mobile phones and the hazard on garage forecourts the bigger risk
is if they are dropped and break in a way to cause sparks or a fire in
the phone, very remote but possible,

and the risk of a spark from e.g. dropping your keys ?
