At around 18:00 on August 4 local time, a severe explosion occurred at the port of Beirut, the capital of Lebanon. http://p8.itc.cn/images01/20200824/cf6a99cc12534667b47032fd2f483403.png The shock wave generated by this explosion was extremely powerful; buildings within a 2-kilometer radius of the accident site were destroyed. Cyprus, a Mediterranean island nation 180 kilometers away, was also affected. Several chemical explosion accidents have also occurred in our country recently. On August 1, a fire broke out at a chemical plant in Panjin, Liaoning ； On August 3, a flash explosion occurred at a chemical plant in Hubei Province. The consequences of a chemical explosion are unimaginable; what should we do if we unfortunately encounter such an incident? How can one save oneself? Vivi will give you some tips today: self-rescue methods after an explosion. In the event of an explosion, evacuate immediately as soon as possible. 1. Those who are near the explosion area should evacuate right away. When evacuating, bend over as you move forward; if there is thick smoke, use a wet towel to cover your mouth and nose, and avoid using elevators or escalators ； 2. A second explosion is very likely to occur; never gather to watch ； 3. When evacuating, care should be taken to ensure the safety of the elderly and children. When evacuating, move in the upwind direction; evacuate quickly in that direction, and do not head straight toward the area where the explosion occurred ； 2. If the explosion occurs in the upwind direction, the correct way to evacuate is to first go around the site of the explosion and then move towards the upwind area ； 3. Try to stay away from the underside of buildings to avoid glass falling due to shockwaves. If you fail to evacuate to a safe place immediately and are trapped inside a building or among the ruins, don’t panic; you should act in this way to save yourself! When trapped indoors, 1. Seal all doors, windows, and vents with tape, and take shelter in a room on the inside with few windows ； 2. Do not stand by windows, glass doors, or other areas with potential hazards ； 3. If something falls around you and gets stuck under a sturdy dining table or desk, quickly move away once the falling stops ； 4. Pay attention to television, radio, and the Internet to stay informed at all times. When trapped under rubble, 1. signal rescuers by whistling, using a flashlight, or tapping on pipes or walls ； 2. Avoid shouting unless it’s absolutely necessary, and refrain from unnecessary movement to prevent inhaling large amounts of dust ； 3. Try to breathe by covering your mouth and nose with cotton fabric. In the event of an explosion, never stay to watch; evacuate immediately in the direction of the upwind side. Don’t gather around! Because a second explosion is very likely to occur. If you are injured in an explosion, be sure to seek medical attention promptly!
