How to escape in the face of dangerous chemicals explosion

In the face of the explosion of dangerous chemicals, how citizens should save themselves and escape has become a hot topic. The reporter today specially interviewed Zhang Yi, a professor at the School of Chemistry and Chemical Engineering of Central South University. Zhang Yi introduced that in many cases, the damage of shock waves is part of the explosion of hazardous chemicals, but on the other hand, the toxic gases generated in the explosion are very harmful to the human body. Therefore, there are a few suggestions:

1. In the explosion of hazardous chemicals, see the light flashing, and immediately hold the breath before the shock wave of the explosion arrives, so as not to inhale the high temperature gas and harmful gas into the body;

2. When escaping, the correct direction should be the upwind of the explosion of hazardous chemicals;

3. The fire caused by the explosion of dangerous chemicals cannot be extinguished by water, and the explosion caused by the fire usually does not end. It is recommended that ordinary people who do not have common knowledge of hazardous chemicals encounter similar situations and protect themselves. , immediately leave the scene;

4. If it is close to the explosion site, it is recommended to choose a solid shelter to avoid, glass, doors and windows are all wrong choices, try to stay away;

5. Encounter a similar explosion. If conditions permit, try to wet your body. If conditions are limited, try to wet your hair as much as possible to avoid burns or hair smoldering when the shock wave arrives. When you are at the same time, try to cover your nose and mouth with a wet towel;

6. Escape posture: Leave the scene in a half-squatting position or crawling. Because the explosion is hot air, toxic gases are also high, so try to lower your body.
