because the phone radiation electromagnetic waves, that light is electromagnetic waves, would not even have light can not have.
If the concentration of flammable gases in the air is large, it can easily cause an explosion. And some scholars have pointed out that the electromagnetic waves emitted by the mobile phone and the fuel warfare equipment may cause natural resonance phenomenon, resulting in heat and explosion. Therefore, not only the gas station, mobile phones can not be used in other combustible gas environment, such as chemical plants, oil depots and blasting sites should be closed. Now we go to the gas station refueling, it is natural to turn off the car engine, if you want their lives more secure, please shut down your cell phone.
Mobile phone in the process of answering the phone or the boot process may produce spark, this is a risk factor, if already in the call, it should be ok, what radiation, nonsense, car to the gas station, often see someone in the car with a cell phone Call, and did not see anything.
In the gas stations and gas stations around the atmosphere, there are generally volatile gasoline gas, and some of the poor gas stations on the ground there are gasoline stains, as long as there is a small spark, it may lead to the gas Like the explosion of objects. And the phone's call moment will have a very small spark, and if the phone body aging, the internal circuit short circuit phenomenon, the spark situation will be more serious.
