"The ringer is ringing, and the cell phone is hiding three dangers!" Cell phone technology expert Liu Wei to the "gas station shutdown" to do a more detailed and scientific interpretation: in addition to the phone's internal current changes caused by sparks very dangerous, cell phone antenna once the search for incoming signals, radio frequency reception immediately open, the radiation emitted by the electromagnetic wave is likely to affect the electronic gasoline counter equipment.
Additionally, in the vicinity of the fuel dispenser, the fuel tank cover, the fuel gun nozzle, and even the fuel dispenser handle, shell, etc. are all made of metal, which is bound to aggregate a large number of electrostatic particles, either positive or negative. Usual state, the electrostatic particles balanced distribution, each other safe. But once the cell phone ringer start, the internal electromagnetic field formed by the electromagnetic wave radiation, is likely to stimulate the electrostatic particles attached to the metal object, disrupt its "deployment", electrostatic particles began to run around, in case of small oil mist, fire or explosion will be difficult to avoid.

What other places are best to turn off your cell phone?
Hospitals
"In fact, it's also best to consciously turn off your cell phone when you enter a hospital!" Liu Wei told reporters that cell phone manuals list the use of safety are based on strict science. If you turn off your phone before entering a gas station, it is a conscious effort to protect yourself. Then in the hospital, especially the CT room, nuclear magnetic **** vibration, cardiac operating room and other precision medical places nearby can take the initiative to turn off the phone, is the moral performance of caring for others.
Many instruments in hospitals are highly sophisticated electronic devices with strict requirements for the surrounding electromagnetic or radiation environment. Many people assume that handing over a cell phone before a patient receives special treatment is enough to ensure safe and effective examinations and treatments. Unbeknownst to them, outside the examination area, the exchange of cell phone signals can also reduce the accuracy of medical equipment to confirm the diagnosis, and the more cell phones in standby in a certain area, the greater the pressure of interference that sophisticated medical equipment may suffer. "In fact, many patients' families know that they must turn off their cell phones after entering the examination area, but they ignore the corresponding shutdown signs." Surgeon Ma Huo told reporters that only a few medical areas have built-in electromagnetic shielding equipment, and most electronic medical devices and places are very afraid of signal interference. "But there are patients or family members who enter the hospital as if they still have endless work and phone calls. You know, the ringing outside the operating room here and there, it is likely to jeopardize the lives of others in the operating room ah!" View Full Version >>
Aircraft
In the future, in the process of aircraft takeoff, landing, taxiing, you can not leave your seat or open the luggage rack; in the aircraft illegal cell phone, open the computer, will be fined 2,000 yuan.
The Flight Standards Department of the CAAC has completed the preparation of a draft proposal for the Civil Aviation Flight Standards Regulations. The draft has now been made public on the official website of the CAAC, and a consultation meeting will be held from July 24 to 28
"In fact, it is indeed very likely that the internal circuitry of any cell phone will discharge when it rings or vibrates!" Liu Wei, a technical engineer for Changhong cell phones, explains, "The normal standby internal current of a cell phone is only about 10 milliamps. But when the antenna searches for an incoming signal, the RF, background light, earpiece and other circuits are immediately activated, and even if the user doesn't press the answer button, the cell phone's internal current instantly increases to 2.5 to 3 amperes, which causes an electric spark."
No cell phone at the gas station many people can do, but they will be in a state of standby cell phone don't in the waist or installed in the pants pockets, there are more "dashing" men casually resting on the phone near the gas cap, in fact, this is more dangerous than making a phone call, because gasoline when the gas cap is open, gasoline gun spraying oil, methane, gasoline and other combustible The gas is free to volatilize. At this time, if the nearby cell phone call, a small spark just happened to be caught by the small oil particles, the tragedy of the phone into a grenade will be difficult to avoid. "So it's safest to consciously turn off your cell phone before entering a gas station."
