层流手术室是采取应用空气洁净 技术实现 对微生物污染采取程度不同的把握，达到把握容量环境中空气洁净度适于各类手术之要旨；并供给适宜的温、湿度，制造一个洁净舒适的手术容量环境。由于手术室要严格把握低细菌数及低麻醉气体浓度，以是层流超净装置的稳定性是层流净化手术室的要紧验收指标。由于泰西手术室洁净准则与中国环境存在细微差别，通例的准则和国内区域区域准则都普遍难于确保手术室净化的长期稳定（一般只能3-10年重建、低档工程1年即需要翻新），以是在工程质料关键出现了明显的层次计划。一些知名净化工程集团官网，在通行准则之外，基本都设有自身执行的高于化通行准则的净化指标。
The laminar flow operating room adopts the air cleaning technology to control the microbial pollution in different degrees, so as to meet the requirements of controlling the air cleanliness in the space environment, which is suitable for all kinds of operations, and to provide appropriate temperature and humidity, so as to create a clean and comfortable operating space environment. Because the operating room should strictly control the low number of bacteria and low concentration of anesthetic gas, the stability of laminar flow ultra clean device is an important acceptance index of laminar flow purification operating room. Due to the subtle differences between European and American operating room cleaning standards and China's environment, conventional international standards and domestic regional industry standards are generally difficult to ensure the long-term stability of operating room cleaning (generally only 3-10 years of reconstruction, low-grade projects need to be renovated in one year), so there is an obvious level division in engineering quality. Some well-known purification engineering companies, in addition to the general standards, basically have their own purification indicators that are higher than the international general standards.
1. The clean operation department shall be located in a building with a fire resistance rating of no less than grade II.
2 洁净手术部宜计划为单独的防火分区。当与其他部位处于同一防火分区时，应采取有效的防火防烟分隔措施，并应采取应用耐火极限不低于2.00H的隔墙与其他部位隔开；与非洁净手术部区域相连通的门应采取应用耐火极限不低于乙级的防火门(直接通向敞开式外走廊或直接对外的门除外)，或其他相应的防火 技术实现 措施。
2. The clean operation department should be divided into separate fire zones. When it is in the same fire compartment with other parts, effective fire and smoke prevention and separation measures shall be taken, and partition wall with fire resistance not less than 2.00h shall be used to separate it from other parts; fire doors with fire resistance not less than class B (except for doors directly leading to open external corridor or directly external) or other corresponding fire prevention technical measures shall be used for doors connecting with non clean operation Department Application.
3 洁净手术部的 技术实现 夹层与手术室、辅助用房等相连通的部位应采取防火防烟措施，其分隔体的耐火极限不应低于1.00H。
3. Fire and smoke prevention measures shall be taken for the technical mezzanine of clean operating department, operating room, auxiliary room and other connected parts, and the fire resistance limit of its separator shall not be less than 1.00h.
4 when indoor fire hydrants are required, fire hydrants may not be set in the operating room, but the fire hydrants set in the operating room shall ensure that the full water column of two water guns can reach any part of the operating room at the same time; when indoor fire hydrants are not required in the clean operating Department, fire hose reels and other fire-fighting facilities shall be set. When automatic sprinkler system is needed
