The sign is because American fuel pumps bizarrely have locks on them so users can leave them unattended while pumping. In the 90s fuel fires were thought to be caused by users being distracted by their phones and overfilling their vehicles.
European ones have locks as well, but they also have a sensor that disengages the lock when fuel level reaches the nozzle. That’s what I’ve seen all over the world TBH.
“Bizarrely”. Great feature and it doesn’t cause fires. They don’t keep pumping endlessly, you know–they stop automatically. And they are very much not locks. They have tiny ridges which can hold the pump handle in place but which easily come undone.
In the 90s … users being distracted by their phones
Do you have a source for that? Cell phones were rare in the 90s. Even then, they weren’t “smart phones” by any sense - they were just used for talking. No text, no apps, no games. Cell phones didn’t become common distractions until the early 00s.
I was taught the problem with lockable handles became apparent in the 00’s when E85 became a thing, as it ignites much more easily from static discharge than gasoline or diesel.
Maybe I was taught incorrectly, maybe you guys had E85 earlier than us (Sweden).
Definitely not an E85 thing. Gasoline fumes will ignite very easily from any spark of basically any type of normal petrol. It’s kinda’ exactly what it’s refined to do…
I was incorrect. The problem is E85 has no problem burning down into the tank, where a large pressure increase could make the tank rupture and a large fire break out. Petrol kills the fire if the ratio fule:air becomes too rich, E85 does not.

They have automatic shutoff valves tho.

American ones have sensors too and have had them as long as I’ve been alive.
Locks are illegal here.
Where is “here”?
Britain

Are you talking about pumps from the 90s?

Heat up in the drivers’ seat, or just grab a pack of gum from the glove compartment. Enough to charge up statically and become a fire hazard.
America got addicted to “convenience”. TV remotes, fair play. But then they had to go too far.
