Not just young people, nowadays people of almost all ages are increasingly unable to leave their mobile phones, and even carry a mobile phone with them in the toilet. However, mobile phones are not suitable for all occasions. Do you want to use a cell phone on these occasions, you know? How do these places use cell phone jammer to ban mobile phones?
1.Gas stations are forbidden to use cell phones
It is a well-known thing to ban the use of mobile phones at gas stations, but it is also one thing that is extremely unappreciated. Using a mobile phone at a gas station, making a call, may be caused by a magnetic field generated by the signal, causing an explosion, so the gas station will set a reminder to prohibit the phone.
Why can't I use my mobile phone at a gas station?
The gasoline in the gas station itself cannot be absolutely sealed, and some gasoline will leak and float in the air. When you use your cell phone, the radio waves emitted by the cell phone generate a wireless current that is sparked when it comes into contact with corrosive metals or poor contact. If such a radio frequency spark encounters a flammable gas danger zone formed by volatile gasoline, it will directly cause a fire, and a serious explosion directly causes a big explosion.
2.Hospital laboratory, operating room
In fact, it is not recommended to use a mobile phone in hospitals such as operating rooms and laboratories. On the one hand, due to the precision of the instrument, the radio waves of the mobile phone will interfere with the normal operation of the device.
Meeting rooms are generally prohibited from using mobile phones. If you are having a meeting with your boss, the moment your phone rings, it means your career is over.
