When the battery starts or when the incoming call rings, our mobile phone will produce tiny sparks of electric current. Although we don't notice it in normal times, in some dangerous places, this tiny spark is enough to cause a fire. Therefore, the relevant laws expressly prohibit the use of mobile phones and other devices in places such as gas stations and oil depots. Although a lot of relevant laws and regulations have been promulgated, the situation in terms of supervision and performance has not been ideal. This is the case with the gas station we are talking about today. Although many gas stations are open and the ventilation effect is better, there are inevitably some people's habitual problems. At the gas station, they will answer the incoming call or make a call in the gas station regardless of the notice prohibiting answering and making calls. In the process of answering or dialing with a mobile phone, it is very easy to cause a serious fire accident due to the weak sparks generated by the mobile phone. Therefore, according to the company's investigation, many gas stations now have Man Uses Cell Phone Blocker Tampa devices installed to prevent such accidents from happening by blocking mobile phone signals. The scope of shielding the signal is not only within the gas station, but also within a distance of at least 5 meters around the gas station cell phone jammer . This is because today's mobile phone signals are almost everywhere, and all electrical equipment is surrounded by them.
When the mobile phone is not in use, the interference of this heavily surrounded signal to other Man Uses Cell Phone Blocker Tampa equipment is negligible, because when the mobile phone is not in use, there is no data communication between the mobile phone and the base station, and it will not constitute a sudden change 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 the mobile phone, there is data communication between the mobile phone and the base station, and a random sudden change signal occurs, so that a dynamic electromagnetic field is formed around the mobile phone signal jammer device. This dynamic electromagnetic field signal will induce sudden changes. The interference signal is easy to cause the malfunction of electrical equipment. There have been many incidents of fires at gas stations caused by the use of mobile phones across the country. Because the mobile phone signal jammer system was not installed, a gas station exploded because the driver used his mobile phone when refueling, resulting in a serious accident that killed and injured many people. The dangers posed by the use of cell phones at gas stations have led to a number of concerns. Relevant departments in Beijing, Hunan, Inner Mongolia, Guangdong, Henan, Henan, Jiangxi, Sichuan, Chongqing and other places have suggested that gas stations under their jurisdiction use mobile phone signal jammers.
