When suspicious explosives are found, do not move easily if you do not understand the situation, to prevent the installation of anti-moving devices and cause unnecessary damage. Xinxing reminded that emergency protective measures and treatment measures should be taken immediately, waiting for professionals to deal with them.
(1) Explosion-proof blanket covering method
The explosion-proof blanket is made of special materials such as explosion-proof fiber. When the covered explosive explodes, the explosion-proof blanket can prevent the shrapnel from scattering and reduce the damage caused by the shock wave generated by the explosion. For suspicious explosives that have not been touched, if there is no need to remove them immediately, you can use an explosion-proof blanket to cover the suspicious explosives and wait for the detonator to deal with them. When implementing coverage, the explosion-proof fence should be used to surround the suspicious object, and then the two people should respectively pull the four corners of the explosion-proof blanket and gently cover the suspicious object. Try to maintain a certain space with the suspicious explosive. Avoid using explosion-proof blanket Directly cover the suspicious object or wrap the suspicious explosive with an explosion-proof blanket, otherwise it will affect the explosion-proof effect and increase the difficulty of later disposal. At present, some large shopping malls and related units have been equipped with explosion-proof blankets, which have achieved good results in actual use. For example, when a suspicious explosive was found in the Xinbai store last year, when the anti-explosion team arrived, the security personnel of the mall had covered the suspicious object with an explosion-proof blanket in time to avoid panic and chaos caused by large-scale isolation.
(2) Long-distance rope hook line movement method
For suspicious objects that have been moved or have not been moved, but must be removed in time (such as when an important person is about to pass through and find suspicious objects), you can try to use a rope hook to move the explosives at a long distance. It was transferred to an empty safe area, waiting for professionals to deal with it, and to ensure that there was no personnel and important facilities such as buildings, water, electricity, and gas within a safe distance of the site.
(3) Liquid nitrogen cooling method
If the explosive has been pulled or lifted by someone, and there are abnormal sounds of clocks and other moving objects in the suspected explosive, you can borrow or purchase a special liquid nitrogen bottle from the chemical department to freeze the explosive with liquid nitrogen. When implementing the liquid nitrogen freezing method, first put the suspected explosive into a closed container (such as a large insulated barrel) that can hold the suspected explosive, slowly pour the liquid nitrogen to immerse the explosive, and then keep the liquid nitrogen immersed in the suspected explosion The state of the matter is waiting for the detonation professional to arrive. When implementing liquid nitrogen cooling, wear anti-freeze protective gear such as gloves. Be careful when pouring liquid nitrogen to prevent frostbite from liquid nitrogen. Liquid nitrogen should be added in time after volatilization.
(4) Put into explosion-proof tank
For suspicious explosives, especially suspicious explosives inside the room (such as the waiting room of the airport, railway station, long-distance bus station, subway platform, and large shopping malls), if they have been mobilized or moved, they can be put into the explosion protection set in advance Inside the tank, wait for the detonation professionals to come to the disposal. When using this method, it is necessary to pay attention to: (1) The design anti-explosion capacity of the explosion-proof tank, only when the estimated amount of explosive in the suspicious explosive is less than the designed anti-explosion capacity of the explosion-proof tank, can the suspicious explosive be put into the explosion-proof tank. Otherwise, the explosion will cause more serious consequences. (2) It is not necessary to cover the explosion-proof tank when outdoors, but must be covered with the explosion-proof tank when indoor, in order to reduce the damage of the top layer by the shock wave.
Try to stay away from suspicious explosives, reduce the stay time, and report to the police in time. Don't take it lightly and take care of it, so as to avoid greater damage and impact due to improper handling methods.
