Civil air defense engineering core 5 and core 6 have a higher level.
The resistance level of civil air defense projects is mainly used to reflect the ability of civil air defense projects to withstand enemy nuclear attacks and conventional weapons. Its nature is somewhat similar to the earthquake resistance of ground buildings, and it is a kind of national defense capability. manifestation. The resistance levels of my country's civil defense projects are mainly divided according to the magnitude of ground overpressure against nuclear explosion shock waves and the destructive effects of conventional weapons.
Therefore, the resistance indicators of civil air defense projects are often dual. For example, the resistance level of an air defense basement to conventional weapons is level 5 (referred to as conventional level 5), and the resistance level to nuclear weapons is level 6 (referred to as nuclear level 6).
Common civil air defense projects include: air raid shelters, tunnel projects, tunnel projects, stacked projects, excavation projects, command and communication projects, medical rescue projects, personnel shelter projects, etc.

Usage
Civil air defense projects have good protective performance. However, in order to play its due role, the correct usage methods and requirements must be mastered to achieve the purpose of protection. . People who are to be sheltered should pay attention to the following aspects.
1. After receiving the early warning order to enter the wartime state, you must remain calm and composed, obey the unified command of the city civil air defense headquarters, and make protective preparations quickly and orderly.
2. Be prepared to bring items when entering the shelter of civil air defense projects: including airtight storage of non-perishable food and drinking water, commonly used personal medicines, flashlights, equipment that can be used as personal anti-virus, personal necessities and documents wait. Do not carry odorous, flammable or explosive items. Packages brought into the project should not be too large and should be easy to get in and out of the project.
3. Understand various air defense warning signals and their corresponding action contents, and be familiar with the location of the project to be covered, the shortest route to the project, and the identification signs of the entrance to the civil air defense project during the day and night.
4. After hearing the air raid siren, enter the nearby civil air defense project as quickly as possible. When entering a civil air defense project, stay calm and obey the organizational instructions of the civil air defense staff. Do not cause confusion and crowding at the entrance of the project, which will affect the speed of entering the project.
5. It is strictly forbidden to use open flames in civil air defense projects, do not smoke, drink less water, and do not defecate in public. Food residues and garbage must be stored in a centralized and airtight manner.
6. When waiting for shelter, sit and lie quietly, move less, do not play, maintain physical strength, and reduce oxygen consumption in the project. Do not tamper with various equipment in the project.
7. When accidents such as collapse or poison leakage occur in part of the project, the people to be sheltered must use simple protective equipment for personal protection, obey the instructions, transfer in an orderly manner or carry out isolation and protection work. They must not Create confusion.
8. Before the air raid alarm is lifted, the sheltered personnel are not allowed to open the door and leave the project to prevent the surrounding contaminated air and radioactive materials from being brought into the project. After the alarm is lifted, it is necessary to prevent people from suddenly crowding out of the civil air defense project, causing chaos and crowding.
