Understanding the Impact of Mobile Phone Signals on Electronic Devices
When we are not using our phones, the electromagnetic field surrounding electronic devices remains relatively stable and static. This static electromagnetic field has minimal interference on other devices since there is no data exchange between the phone and the base station, resulting in no sudden signal fluctuations. However, when we use our phones, the data exchange between the phone and the base station generates random signal fluctuations, creating a dynamic electromagnetic field. This dynamic field can induce disruptive signals, leading to malfunctions in electronic devices.

The ignition of sparks caused by mobile phone usage during battery startup or when the phone rings can potentially lead to fires. Recognizing this risk, authorities in the petroleum, chemical, and safety sectors have implemented regulations prohibiting mobile phone usage at gas stations. However, the enforcement of these regulations has not been ideal. Gas station equipment is computer-controlled, and mobile phone signals can interfere with their normal functioning, resulting in inaccurate measurements. Moreover, the sparks generated during phone calls can easily ignite fires, leading to gas station explosions.
Given the high fire risk, gas stations, which are considered fire-prone areas, not only strictly prohibit mobile phone usage within their premises but also recommend refraining from using phones within a two to three-meter radius around the station. Additionally, gas stations should prominently display signs prohibiting phone calls and widely disseminate safety information to raise awareness about the dangers of using mobile phones at gas stations. Several incidents of fires caused by mobile phone usage have already occurred nationwide, including major accidents resulting in multiple casualties in Henan and numerous fire incidents in Shenzhen and Chongqing.
The dangers associated with mobile phone usage at gas stations have garnered significant attention. Authorities in Beijing, Hubei, Inner Mongolia, Guangdong, Henan, Shandong, Jiangxi, Sichuan, and Chongqing have recommended the use of mobile phone signal jammers at gas stations under their jurisdiction. To lead by example, China Petroleum & Chemical Corporation (Sinopec) and China National Petroleum Corporation (CNPC) have already implemented the use of mobile phone signal jammers at select gas stations in certain regions.
The risks posed by mobile phone usage at gas stations have prompted various stakeholders to take action. It is crucial for gas stations to strictly enforce the prohibition of mobile phone usage and raise awareness among the public about the dangers associated with using phones in these areas. By implementing preventive measures such as mobile phone signal jammers and promoting safety knowledge, we can ensure that using mobile phones at gas stations is recognized as a hazardous practice.
