We understand from the passage that explosions at petrol stations ----.

There have been stories in the press about mobile
phones sparking explosions at petrol stations. But
according to the GSM Association, a worldwide body
for mobile phone makers, none of these reports has
ever been traced back to a real event. But there is a
real safety concern, and it's not about radio
emissions from mobiles as you might have thought.
Instead, the GSM Association says there is a
theoretical risk that if a hand-held phone is dropped
and the battery separates from the phone, it could
cause a spark across the contacts. This is equally
true of other battery-powered devices such as
torches, Walkmans and CD players. But it's far more
likely that mobile phones cause a hazard at petrol
stations by distracting their users while they're
operating a petrol pump.
