Hazardous area safety issues

I personally believe that you should turn off your phone when entering a dangerous area, and it is best to enter without a mobile phone. Don’t let your mobile phone turn into a grenade. A few days ago, I saw a report of a safety incident. An explosion occurred at a gas station in the West District of Sao Paulo, Brazil. The cause was a gas station worker answering his cell phone while unloading gas. According to reports, the 45-year-old worker Carlos took out his mobile phone from his pocket to answer a call while unloading oil from an oil truck, causing an explosion. Three-quarters of the worker's skin was burned and he was seriously injured. After seeing this news, I was not only worried about some gas stations. Although there are obvious signs prohibiting the use of mobile phones inside the gas stations, there are still many drivers and customers talking on mobile phones under the canopy of the gas station, next to the gas pump or in the oil tank area. The author believes that there are many reasons for this phenomenon. First, people do not have enough awareness of the dangers of making and receiving mobile phone calls on the site. In the eyes of many people, there is no danger in making phone calls at gas stations. In fact, the radio waves (radio frequency electromagnetic radiation) emitted by mobile phones can cause the mobile phone antenna that receives the radio waves to generate radio frequency current. When the radio frequency current does not circulate smoothly between metal conductors, radio frequency sparks will be generated. The mobile phones we currently use do not have explosion-proof functions. When the power is turned on, the mobile phone light is on, or the mobile phone rings, it may release enough energy to generate sparks. When the radio frequency spark is greater than 6 milliwatts and lasts for more than 1 microsecond, its energy is enough to ignite the mixture of fuel vapor and air. In gas stations, due to the need to constantly refuel vehicles, there must be a certain concentration of oil vapor in the air. Especially in rainy or foggy weather, the air circulation is poor and oil vapor accumulates faster, making the risk even greater. Petrobras tested the dangers of answering cell phones at gas stations in 2003, but it only took more than 20 tests before an explosion occurred. Second, the company did not sufficiently publicize the ban on mobile phone calls on the site. The author asked some driver customers at the gas station, and a considerable number of them did not know the regulations prohibiting mobile phone calls and calls at the station, and they were not clear about why they were not allowed to use mobile phones. There are also many gas station employees who don’t know the reasons and dangers of banning cell phone calls at gas stations.

In fact, there is a lot of content in this area in the forum. You may wish to search for "mobile phone" to see the link.: http://bbs.hcbbs.com/search.php?searchid=658&orderby=lastpost&ascdesc=desc&searchsubmit=yes in addition: I recommend you read this narrative http://bbs.hcbbs.com/viewthread.php?tid=353196&page=2#pid1839301

Nowadays, there are explosion-proof mobile phones. In fact, in most cases, it will be okay to answer the phone.
