What is a clean area and what is a contaminated area? What is a sealed partition wall?

In order to reduce the scope of air damage, for the larger area of the human defense project to be divided into protective units, protective units for the protection of facilities and internal equipment can be self-contained system of the use of space. The partition wall between two protective units is the protective unit partition wall. Because the protective unit must have the ability to survive independently, protective unit partition wall for the protective unit is the human defense enclosure, the specification also requires it to be able to withstand the corresponding explosive load. Construction should be protective unit partition wall according to the air wall for quality control, through the protective unit partition wall of the pipeline practice and wear the enclosure structure is basically the same requirements.

Personal defense zone can meet the requirements of anti-virus is divided into clean and poisoned area. Clean area is the main area of wartime sheltering personnel and materials. Dyeing area is generally in the mouth of the human defense project to assume the role of isolation, exclusion and filtration of the outside world toxic agent, in addition to the human defense power station generator room, medical ambulance station triage room, the professional team vehicle shelter area in the function of the protective space allows the dyeing of toxicity is also located in the area of the dyeing of the toxicity.

Generally, the area within the last closed door of the civil defense project for the clean area, protection of the closed door and the last closed door between the area for the poisoned area (wartime ventilation system from the hanging plate trapdoor to the innermost manual closed valve between the area for the poisoned area). Contaminated area and clean area is closed to each other in the area of human defense protection, contaminated area mainly includes diffusion room, closed channel, anti-virus channel, decontamination room (simple decontamination room), filtration room, remember these parts can help us quickly determine the location of the contaminated area. Generally, the area of the poisoned area in the project is relatively small, find the poisoned area after the rest of the human defense zone is the clean area.

The partition wall that separates the contaminated area from the clean area is the airtight partition wall. Closed partition wall to assume the role of anti-virus in the human defense specification of the closed partition wall has a number of strict requirements. Such as human defense design specification 3.2.13 (strong article) provides: "in the poisonous area and clean area should be set up between the whole poured reinforced concrete closed partition wall, its thickness should not be less than 200mm. when the closed partition wall on the pipeline through, it should be taken to take airtight measures. When a doorway is opened on the airtight partition wall, an airtight door shall be provided."
