Why Can't You Make Phone Calls While Refueling Your Car?

Prohibiting phone calls during refueling is to avoid explosions. Here is a detailed explanation: 1. When the concentration of gasoline in the air exceeds 1.3% to 6%, an explosion can occur. 2. Especially in summer, high temperatures cause gasoline to evaporate quickly, leading to higher gasoline concentrations in gas stations. Once the concentration reaches a certain level, even the smallest spark or invisible static electricity can trigger an explosion. 3. Therefore, all electrical devices in gas stations must have fireproof and explosion-proof functions, including even light bulbs. 4. However, all mobile phones currently available on the market (including CDMA phones) do not have explosion-proof capabilities. Thus, pressing buttons on the phone can generate static sparks, which may easily cause an explosion.
I never make phone calls while refueling, mainly because the safety risks are too high. During the refueling process, gasoline releases a large amount of flammable fumes, and these vapors can quickly explode and ignite upon contact with any spark. When making a phone call, the phone itself can generate static electricity or electrical fault sparks, and getting in and out of the vehicle can also accumulate static electricity—a simple action like pulling out your phone can produce enough static spark to ignite the vapors. A friend of mine witnessed a minor accident at a gas station caused by someone making a call, where a spark ignited the fuel vapors, nearly causing a major fire. Not only is it dangerous for yourself, but it can also endanger people and property around you. Remember, safety first: turn off the engine while refueling, don’t touch your phone, finish refueling before handling calls—this habit can save lives.
