eli5: Why is there a -no mobile phone- sign at gas stations?

249 views

There are always signs that show the ban of cigarettes, matches and phones at gas stations. I can imagine fire being dangerous around gas, but you can’t possibly blow up a gas station with a mobile phone, can you?

Many people here are saying that cellphone can’t cause any problem at a gas station because some tv show have debunked it.
This is wrong. You can’t prove that something can’t happen by only testing a couple of times and see if it does or does not happen (It’s difficult to prove a negative outcome).

In electrical and electronics you also have approved equipment for use in an area with a high risk of explosion (often marked “EX”). Like at a gas plant or an oil rig.
This is equipment that has been proven to not be able to cause an explosion in dangerous areas. Like properly tested! And your cellphone is not one of those.

But you can get special phone that are approved.
