一般大型化工爆炸可能会遇到的问题：离爆炸处相对远的位置因冲击波导致的划伤、摔伤、出血。短期内大量通讯导致的暂时性通讯中断。大量人群转移导致的交通拥堵。未知的爆炸物伤害、二次爆炸、以及可能存在的有毒烟雾。医院都是人。建议处理方案：爆炸区较近的人，如果不是 EHS 专员，第一时间撤离而不是冲上去灭你搞不定的火。
I personally experienced chemical, Jihua explosion happened in Tianjin, feeling like a repeat of the general. The problem that a large chemical explosion may encounter is the injury, injury and bleeding caused by shock waves far away from the explosive place. Temporary communication interruption caused by a large number of communications in the short term. Traffic congestion caused by a large number of people transferred. Unknown explosive damage, two explosions, and possible toxic smog. The hospital is all human. Proposal treatment: the people near the explosion area, if not the EHS Commissioner, take the first time to evacuate rather than go up and put out the indeterminate fire.
撤离时如有余力可以看一下附近是否有需要帮助的人，提醒或协助一起撤离。撤离时注意弯腰前行、上风口方向绕行爆炸物、如有浓烟湿毛巾或防毒面具遮住口鼻、避免乘坐电梯扶梯。出来后按照规定联系公司 EHS 专员等人员通知情况并报警。如有可能提供爆炸区域位置、爆炸物信息、储量、附近储存物品信息。方便报警时消防部门采用更有效的方案。爆炸很可能还有后续，不要围观，不要围观！一般会有人会需要紧急处理皮肤创伤。这里可以参考下面两个问题。皮肤创伤擦伤的正确治疗方法是什么？
If there is a surplus of power to see if there is any person in need of help in the vicinity, reminding or assisting to evacuate. When evacuating, pay attention to bend over and bypass the explosives in the direction of the upper air vent, such as thick wet towels or mask to cover the mouth and nose, and avoid elevator escalator. After coming out, contact the EHS Commissioner and other personnel in accordance with the regulations and notify the police. It is possible to provide information about the location of the explosion area, the information of explosives, the reserves, and the storage of the goods nearby. The fire department adopts more effective plan when it is convenient to alarm. The explosion is likely to have a follow-up, do not look around, do not look around! In general, someone will need to deal with the skin trauma urgently. Here we can refer to the following two questions. What is the correct treatment for skin trauma?
- 生活常识。爆炸冲击波导致的二次伤害一般应如何急救和自救？ - 医学如果更严重那么及时清创止血后去医院接受进一步治疗。这时候打 120 很难打通。如果是爆炸区域附近的人，及时撤离危险区域，并求救，相对较远的人一般伤势不会太重，可以步行去医院寻求救助。如果有能力尽可能选择离爆炸区域较远的医院，一方面把重要的资源让给可能伤势更重的人，另一方面近处的医院一般会伤员满满，很难快速得到救治。注意小孩的情况，给以安全感，避免紧张情绪。同时注意一些东西不要让小孩子看到！尽可能避免创伤后应激障碍。手机几乎一定会打不通电话的，3G\\4G 网络一般也会出现问题。有线网络反而是相对稳定的，如果需要联系他人，建议采用通过网络方式联系。大概个把小时候通讯会逐渐恢复，届时再进行必要的联系。不是所有爆炸带出的气体都是危险的。这个更多取决于爆炸物的成分、总量、距离、风向等等。
- life common sense. How should the two injuries caused by the blast shock wave be first aid and self rescue? - medical treatment will be further treated in the hospital if the blood is debrided in a more timely manner. It's hard to get through at this time of 120. If the people near the explosive area evacuate the danger area in time and ask for help, a relatively distant person will not be injured too much. He can walk to the hospital for help. If we have the ability to choose hospitals far away from the exploding area, we should give important resources to those who may hurt more. On the other hand, the hospitals near here will usually be full of wounded, so it is very difficult to get treatment quickly. Pay attention to the child's situation, give a sense of safety, avoid tension. At the same time, pay attention to something not to let a child see it! Avoid posttraumatic stress disorder (PTSD) as much as possible. Mobile phones are almost impossible to get through, and 3G\\4G networks usually have problems. The cable network is relatively stable, and if you need to contact others, it is suggested that the network be used. The communication will gradually recover when it is small, and then the necessary connections will be made. Not all the gases from the explosion are dangerous. This depends more on the composition, total, distance, wind direction, etc. of the explosive.
In fact, many places with a certain distance from the explosion area do not need to be evacuated. The first time to close the doors and windows, do not go out to see the bustle. Turn on the TV and radio to the local radio station or program, and put your cell phone around to receive emergency SMS. If it is found that there is a pungent odor, near the explosion point and at the downstream outlet, receiving the evacuation notice from the District, EHS Commissioner, school organization, or finding that someone has evacuated, evacuate in time. (Jilin chemical explosion is the school started in almost half an hour after contact organized evacuation, of course, if it is not assured, can also go) evacuation is in principle may be left under the outlet gas pollution direction, is to leave the polluted area and polluted area of potential future. But don't go up to the vent in the area of the explosion!!! The upper air vents are windward or vertically moving the explosion area, and the lower air inlet moves toward the vertical wind direction away from the explosion zone. In addition to considering the change of wind direction, a sea breeze of wind can be considered sooner or later. The gas, electricity, water and doors and windows are closed at the time of departure. This is not an earthquake that needs to escape immediately. It is still possible to shut down the doors and windows. During the evacuation, good money card, mobile phone, charger, water, cold clothing. To wear flat shoes, go. There is no trampling at the far place in the center of the explosion, but the traffic is generally paralyzed at this time. Go with your partner. Avoid other dangers (such as undesirable people). Avoid the bottom of the building as much as possible to avoid the drop of glass caused by shock waves
In fact, the evacuation is not very flurried, people are generally in an orderly way out of the direction. When we leave all the way and not how tense, then the second day night night cafes, taxi back on the end of the batch...... In time to listen to local channels and pay attention to receiving SMS, people and institutions will generally provide temporary shelter. After a few hours, there will be a continuous report, and the event will be effectively controlled, and this time you can decide whether to go back. (Jilin chemical explosion shortly after the radio almost switched to the rescue mode, has been providing emergency shelter, on repeat and to the people of Jilin and Jilin's praise!) Please do not pass rumors! Please do not pass rumors! All unofficial channels, even the news media, do not believe it, because they are generally guesswork and not very reliable. After that, there are usually two explosions, such as XXX, drug leakage and so on. Don't believe it or believe in official channels. At this time, the government is ten thousand times more reliable than many bad media. (and the fact that when rumors abound after the explosion in jilin...... And then it doesn't happen.) the communication should be recovered after an hour, and it's a safe time for the friends and family. Or find an Internet cafe to be safe. They care about you very much. If the explosion area is near the river, a certain amount of water reserves can be considered, so as to avoid the shortage of drinking water caused by the failure of the fire protection scheme. Don't save
