Explosion-proof mobile phones are mobile phones that do not form an effective ignition source in flammable and explosive environments, ensuring safe communication in flammable and explosive environments. Explosion-proof mobile phones do not mean to prevent the surrounding environment from exploding, but to say that the use of mobile phones in high-risk environments will not become a source of ignition and will not cause an explosion. Because the internal ignition source and circuit of the mobile phone are specially treated, they will be in a special environment immediately. It will not explode. At present, explosion-proof mobile phones have been widely used in major flammable and explosive places. Such as chemical plants, gas stations, natural gas, petroleum construction sites, pharmaceutical plants, etc. With the development of the Internet of Things industry technology, handheld terminal charging is becoming more and more widely used in various occasions, which greatly facilitates the use of cardholders and improves the current card acceptance environment. However, in some specific industries, can handheld terminals be used for charge management. The CONQUEST S8 safety explosion-proof hand-held terminal launched by Kangkaisite Communication Equipment Co., Ltd. has passed the explosion-proof test of the explosion-proof quality supervision and inspection center of electrical products of China Petroleum and Chemical Industry and obtained the corresponding explosion-proof certificate. This explosion-proof handheld device uses an intrinsically safe circuit design and is suitable for hazardous locations with IIC-grade explosive mixtures, such as petroleum, chemical, storage, dock, and mining industries.  In addition to the warning signs "Strictly Prohibited Fireworks" at gas stations, people often see the related slogans "No mobile phone calls". A gas station is a special place that is prone to leaking explosive gases such as gasoline and natural gas. Especially in summer, the temperature is high, the gasoline volatilizes quickly, and the gasoline concentration in the gas station is high. When it reaches a certain concentration, any small sparks or static electricity not visible to the naked eye will cause an explosion.
Therefore, although this possibility is very small, from the perspective of dangerous goods management, the use of wireless terminals and mobile phones without explosion-proof detection in gas stations is a certain danger. Therefore, gas stations using explosion-proof hand-held terminals must pass national standard explosion-proof testing, which meets national explosion-proof requirements.
At present, at home and abroad, explosion-proof handheld terminals that have been used in gas stations are used indoors away from gas dispensers. No oil company has explicitly confirmed whether an explosion-proof handheld terminal can be used next to the tanker in the gas station. At present, more and more oil companies have explicitly banned the use of mobile phones at gas stations.
