A Connecticut senator, Andrea Stillman, has introduced a bill
into the state legislature to impose a $250 fine on anyone who uses a cell phone while pumping gas. She sees it as a public health issue. Here's her reasoning:
Stillman said there are already warnings pasted on gas pumps informing people that a cell phone in the proximity of a gas pump could cause an electrical charge that might ignite the pump. However, she said, there are no penalties.
Maybe I'm wrong, but I thought that whole thing about cell phones making gas pumps blow up was just an urban legend. Engadget
agrees, pointing out that "there’s no evidence that a cellphone has ever sparked a fire at a gas station."
