With the growing economy, cars are becoming more and more popular, and there are more and more gas stations providing fuel for cars. Frequency jammers have also appeared many times in gas stations.

At present, mobile phone is an indispensable daily communication tool in people's life. After opening the mobile phone in this sensitive area, when the ring rings, the internal components in the mobile phone will generate some energy, which will lead to slight sparks. When the mobile phone is close to the gas station, it may lead to a fire. In order to avoid this problem, frequency jammers can be added in gas stations, which can prevent some tragedies. The security department has regulations prohibiting the use of mobile phones in gas stations. Therefore, in gas stations in important fire zones, frequency jammers should not only be used in gas stations, but also be placed around gas stations.

Nationwide, fires caused by the use of mobile phones have occurred in many places. An explosion occurred at a gas station because the driver used a mobile phone during refueling, resulting in many casualties. Gas stations in Shenzhen, Chongqing and other places also caused many fires due to cell phone calls. The danger brought by the use of mobile phones in gas stations has attracted attention from many aspects. Now gas stations in many regions have used frequency jammers.

When installing frequency jammers in gas stations, it is best to set up some slogans that prohibit calling mobile phones and widely publicize safety common sense, so as to let more people understand and reduce the occurrence of accidents.
