大家知道造成GMP车间净化度不合格的因素都有哪些?

来源:http://www.henganjh.cn │ 发表时间:2020-01-06 

近年来,随着人们居室环境要求的提高,大量的新建筑和装饰材料进入住宅和公共建筑,再加上现代建筑的亲密关系,导致了建筑室内空气污染问题日益突出,严重威胁人类健康,因此一般关注的各行各业。在洁净室使用前,必须打开无菌室紫外线灯照射消毒30分钟以上,打开超净台吹气。术后应及时清理无菌室,使用紫外线灯照射消毒20分钟。任何带有活细菌的物品必须消毒后才能在水龙头下清洗。
  In recent years, with the improvement of people's living environment requirements, a large number of new buildings and decorative materials enter into residential and public buildings, coupled with the close relationship between modern buildings, resulting in the increasingly prominent problem of indoor air pollution in buildings, seriously threatening human health, so the general concern of all walks of life. Before use in the clean room, the ultraviolet lamp in the sterile room must be turned on for disinfection for more than 30 minutes, and the ultra clean table shall be turned on for air blowing. After the operation, the sterile room should be cleaned in time and sterilized with ultraviolet lamp for 20 minutes. Any articles with living bacteria must be disinfected before they can be cleaned under the tap.
  洁净室在一定的洁净度下,其空气流速的测定是根据洁净室的使用等具体情况而变化的。它不仅受到室内扬尘量和过滤效率的影响,还受到其他因素的影响。在工业洁净室方面,影响洁净室清洁度和气流速度选择的主要因素有:

  Under a certain degree of cleanliness, the measurement of air flow rate in a clean room changes according to the specific conditions such as the use of the clean room. It is not only affected by indoor dust volume and filtration efficiency, but also by other factors. In terms of industrial cleanrooms, the main factors affecting the selection of cleanroom cleanliness and air flow speed are as follows:
  (1)室内污染源:建筑构件、人员数量、作业活动、工艺设备、工艺材料、工艺本身均为粉尘释放源,根据具体情况差异较大;
  (1) Indoor pollution sources: building components, number of personnel, operation activities, process equipment, process materials and process itself are all dust emission sources, which vary greatly according to specific conditions;
  (2)室内空气流型及分布:单向流动要求流线均匀均匀,但由于工艺设备布置、位置变化和人员活动的干扰,会形成局部涡流;非单向流动时,为避免死角和温度分层,需要掺混;
  (2) Indoor air flow pattern and distribution: unidirectional flow requires uniform streamline, but due to the interference of process equipment layout, location change and personnel activities, local eddy current will be formed; in non unidirectional flow, mixing is required to avoid dead angle and temperature stratification;
  (3)控制需求的自然净化时间(恢复时间):清洁的恶化会造成的意外释放或引入污染物或中断洁净室的气流或间歇对流或人们的运动和设备在正常操作。自清洗时间控制要求取决于该时间范围(在清洁度恶化的情况下)对产品质量和产量的影响。
  (3) Natural purification time (recovery time) to control the demand: accidental release or introduction of pollutants or interruption of air flow or intermittent convection in the clean room or normal operation of people's movement and equipment caused by the deterioration of cleaning. Self cleaning time control requirements depend on the impact of this time range (in case of deteriorative cleanliness) on product quality and production.
  1. 在无尘净化工程中严格执行无菌操作,防止微生物污染;操作人员应在进入房间前关闭紫外线灯。
  1. Aseptic operation shall be strictly carried out in the dust-free purification project to prevent microbial pollution; the operator shall turn off the ultraviolet lamp before entering the room.
  2. 净化工程配备无菌手术室和缓冲室,无菌手术室清洁度达到10000级。室内温度保持在20-24℃,湿度保持在45-60%。超净工作台的清洁度应达到100。
  2. The purification project is equipped with sterile operating room and buffer room, and the cleanliness of sterile operating room reaches 10000 level. The indoor temperature is kept at 20-24 ℃, and the humidity is kept at 45-60%. The cleanliness of super clean worktable shall reach 100.
  3.洁净室应保持清洁。严禁堆放杂物,防止污染。严格控制所有灭菌设备和培养基的污染。
  3. The clean room should be kept clean. It is forbidden to pile up sundries to prevent pollution. Strictly control the pollution of all sterilization equipment and culture medium.
  4. 无尘净化工程应定期消毒,并使用适当的消毒剂进行清洁,以确保无菌室的清洁符合要求。
  4. The dust-free purification project shall be disinfected regularly and cleaned with appropriate disinfectant to ensure that the cleaning of the sterile room meets the requirements.
