At present, the mobile phone signal is almost everywhere, and all electrical equipments are surrounded by it. When the mobile phone is not in use, the interference of the surrounded signal to other electrical equipment is minimal. This is because there is no data exchange between the mobile phone and the base station when the mobile phone is not in use, and it is impossible to form a mutation signal. The electrical equipment is surrounded by a relatively stable electromagnetic field, that is, a static electromagnetic field. The interference of this static electromagnetic field to the electrical equipment is almost zero. When using a mobile phone, there is a data exchange between the mobile phone and the base station, and a random mutation signal is generated. Neighbors Using Cell Phone Blocker A dynamic electromagnetic field is formed around the electrical equipment. This dynamic electromagnetic field signal will induce a mutation in the interference signal. It is easy to cause malfunction of electrical equipment. When the cell phone battery starts, when the ringer rings, it can generate enough energy to cause a slight spark that can cause a fire. Relevant departments such as petroleum, chemical industry, and security have expressly stipulated that the use of mobile phones in gas stations is prohibited. The equipment of the gas station is controlled by the computer. The mobile phone signal will affect the normal operation of the equipment, which will lead to inaccurate measurement. More importantly, the mobile phone will spark during the dialing process, which can easily cause fire and cause the gas station to explode.
Therefore, the gas station that belongs to the fire prevention area is not only strictly forbidden to use mobile phones in the station, but also it is best not to use mobile phones within two or three meters around the gas station. At the same time, gas stations should set up obvious signs prohibiting cell phone calls, and widely publicize safety knowledge, so that people understand that using cell phones in gas stations is undoubtedly walking with tigers. There have been many fires caused by the use of mobile phones across the country. A gas station in Henan caused an explosion caused by the driver's use of a mobile phone while refueling, resulting in a catastrophic accident that killed many people. There are also many fire dangers caused by mobile phones in gas stations in Shenzhen, Chongqing and other places. The dangers posed by the use of cell phones at gas stations have drawn attention in many ways. Relevant departments in Beijing, Hubei, Inner Mongolia, Guangdong, Henan, Shandong, Jiangxi, Sichuan, Chongqing and other places have advised gas stations under their jurisdiction to use Neighbors Using Cell Phone Blocker . Sinopec Corporation and China National Petroleum Corporation have taken the lead in using gas stations in some regions cell phone jammer .
