Gas stations ban phone calls, use cell phone jammers

As we all know, gas stations dealing with flammable and explosive products belong to high-risk industries, and "safety first" is the most basic requirement for gas stations. Common safety measures at gas stations mainly include refueling after the refueling vehicle is turned off, gas station employees must wear anti-static clothing to work, no fireworks and mobile phone calls in gas stations, and no refueling in plastic buckets, etc. One of the more difficult to manage is the prohibition of customers using mobile phone calls in gas stations. Therefore, it is very necessary to install mobile phone signal jammers at gas stations.

First of all, people have misunderstandings about the safety hazards caused by using mobile phones in gas stations. Why can't I make phone calls at the gas station? Some people think that using a mobile phone at a gas station can cause an explosion is alarmist, and they have never heard of an explosion caused by a mobile phone. In fact, there is a certain scientific basis for mobile phones to cause explosion accidents.


When the gas station fills the fuel tank of a car or motorcycle with gasoline through a fuel gun, the fuel vapor in the original empty fuel tank will drift outward, and the newly injected gasoline will also volatilize into the air, causing the fuel vapor density around the refueling vehicle to increase sharply. At the same time, in order to make the communication signal clearer, the frequency of mobile phone use is very high, and the transmission power is relatively strong. Although it meets the national standard, it still poses a serious threat to refueling and gas stations. The current required to ignite the fuel gas is very small, and the static current generated by the mobile phone in the working state can completely reach this limit. If you encounter cloudy or foggy weather with high air humidity and low air pressure when refueling or unloading oil at the filling station, due to poor air circulation, the density of oil and vapor will increase accordingly, and the possibility of explosion caused by receiving a mobile phone will further increase. big.

In addition, because the mobile phone itself does not have explosion-proof function, if the mobile phone has been used for a long time or the quality of the mobile phone itself is poor, the circuit of the internal chip of the mobile phone is prone to short-circuit, so that the mobile phone can generate a small amount of sparks at the moment of answering, and thus also Can cause an explosion at a gas station.

Secondly, there is a single way to prohibit customers from using mobile phones in gas stations. At present, the main way for gas stations to prohibit customers from using mobile phone calls at gas stations is to persuade, but sometimes the effect of persuasion is not ideal. On the one hand, the customer does not know the safety management regulations of the gas station, and believes that it is unnecessary for the gas station employees to let them use their mobile phones in the gas station, which is prone to rebellious psychology. On the other hand, the customer knew that he could not use the mobile phone in the gas station, but he was lucky, and one-sidedly believed that the accident would not happen when he was using the mobile phone, so he did not listen to the persuasion of the gas station staff and went his own way.

Therefore, the use of mobile phone signal jammers at gas stations can prevent the above-mentioned safety hazards caused by using mobile phones to make calls from the root cause. Of course, ordinary cell phone signal jammer cannot be directly used in special places such as gas stations. It is also necessary to prevent the jammer itself from arcing at the moment of switching on and off, thereby causing safety accidents. Choose a mobile phone signal jammer with explosion-proof performance, and seal the host in the explosion-proof box. Even if the jammer generates electric sparks when the machine is turned on and off, it will be isolated from the outside air, thereby reducing the occurrence of safety accidents caused by the electric sparks generated by the machine itself.
