“Using a cell phone at a gas station is dangerous and can cause explosions.”

The widespread belief that using a cell phone at a gas station can trigger an explosion is a persistent misconception. This myth likely gained traction in the late 1990s and early 2000s, fueled by precautionary warnings from some wireless manufacturers and fire departments, often stemming from an abundance of caution rather than concrete evidence. Unverified reports circulating online and through email also contributed to its spread, creating an "urban legend" effect.

Despite the persistent warnings seen at many pumps, there is no credible scientific evidence or documented case of a cell phone causing a fire or explosion at a gas station. Scientific studies and even extensive testing by programs like MythBusters have repeatedly shown that the radio frequency energy emitted by a cell phone is far too low to generate a spark capable of igniting gasoline vapors. The Petroleum Equipment Institute, after researching hundreds of gas station fires, has confirmed that cell phones are not implicated in these incidents.

People commonly believe this myth due to several factors. The highly visible "no cell phone" signs at gas stations reinforce the idea of a genuine danger. Furthermore, real gas station fires have occurred due to static electricity, which can generate a significant spark, sometimes up to 60,000 volts. If a person happened to be using a cell phone when a static discharge ignited vapors, the phone might be mistakenly identified as the cause. Ultimately, while using a phone at a gas station is discouraged primarily to minimize distractions and ensure safety from other hazards like moving vehicles, the risk of it causing an explosion is negligible.
