I've seen gas stations that explode, and every time you see someone on their cell, their taking a chance. Saw a guy yesterday, NO JOKE, smoking a cigarette, one pump over from where I was filling up. Now, he stood back TWO steps as he let the auto shut of run, but COME ON, that's just not very bright.
I see the same thing from time to time. Unfortuately the CNG fueling stations are operated at about 2000 psig. Every incident may bring the safety issue to the surface. I believe the CNG stations are safe, but 2000 psig will scare most because they are not educated on such things.
