Problems encountered by large-scale chemical explosions under normal circumstances:
1. Scratches, falls, and bleeding caused by shock waves are relatively far from the explosion. Temporary communication interruption caused by large amounts of communications in the short term. Traffic jams caused by mass crowd movements. Unknown explosive damage, secondary explosions, and possibly toxic fumes.
2. People nearer to the blasting area, if not EHS specialists, will evacuate for the first time instead of rushing to extinguish the fire. If there is more energy available at the time of evacuation, you can see if there is anyone in the vicinity who needs help. Remind or help with the evacuation. When evacuating, pay attention to bending forward, bypass the explosives in the direction of the air outlet, cover the nose and mouth with a heavy smoke damp towel or gas mask, and avoid taking the elevator escalator. After coming out, contact the EHS Commissioner and other personnel in accordance with regulations to notify the situation and call the police. If possible, provide information on the location of explosive areas, information on explosives, reserves, and nearby stored items. The fire department uses a more effective solution when the alarm is convenient. The explosion is likely to follow, don't look around! In general, some people will need to deal with skin trauma urgently. It's difficult to get through 120 at this time. If people are in the vicinity of the explosion zone, they should evacuate the danger zone promptly and ask for help. People who are relatively far away are generally not too injured and can walk to the hospital for help. If there is the ability to choose the hospital farther from the blast zone, on the one hand, it will give important resources to those who may be seriously injured. On the other hand, nearby hospitals are generally full of wounded people and it is difficult to quickly obtain treatment.
Mobile phones will almost certainly not be able to make calls, and 3G/4G networks will generally have problems. The wired network is relatively stable on the contrary, and if it is necessary to contact other people, it is recommended to use the network mode.
Not all the gases brought out by the explosion are dangerous. This depends more on the composition, total amount, distance, wind direction, etc. of the explosive. In fact, many places that are a certain distance from the explosion area do not need to be evacuated. Close doors and windows the first time, do not go out to watch lively. Turn on the TV and broadcast to a local radio station or program, and the mobile phone is on hand to receive emergency messages. If you notice a pungent odor, get closer to the explosion point and downwind, receive a notice of evacuation from the community, the EHS specialist, the school organization, or find that someone has evacuated, then evacuate in time.
At the time of evacuation, in principle, it is the direction from the lower vent that may be contaminated by gas. It is necessary to leave the polluted area and the potential polluted area in the future. However, don't go to the explosion area and go to the top! ! ! The upwind outlet moves in the direction of the wind or vertically. The downwind moves toward the vertical wind direction away from the blast zone. In addition, wind direction changes should be taken into account. In the case of land and sea breeze, morning and evening winds can be considered. Turn off gas, electricity, water, doors and windows when you leave. This is not an earthquake that needs to be evacuated. It is still possible to close doors and windows. There will be no trampling in places far away from the blast center, but traffic is generally rampant at this time. Avoid other dangers (such as ill-mannered people). Avoid the bottom of the building as much as possible to avoid dropping the glass caused by the shock wave.
