Disinfection step by step
  Prior to the biodecontamination, it is important to clarify the requirements:
    What is the bioburden reduction objective (log₁₀ 4, log₁₀ 5, log₁₀ 6)?
    Where should the indicators be positioned?
    How will the effectiveness of biodecontamination be validated, with which indicators (chemical, biological)?
    Is the space to be treated very cluttered (full trolleys in an airlock for example, equipment in place in a BSC, etc.)?
    Is there one or more zone(s) to biodecontaminate simultaneously?
  To establish a protocol that meets the specifications, Devea’s team can support you: with experience that covers several business sectors, they will be able to save you time by taking advantage of their expertise gathered along the projects carried out with the users.

On the disinfection day
  On the D-Day, once the space has been cleaned, the Phileas® solution is quick and easy to set up:
    Place the Phileas® device with a full biocide container in the center of the zone, making sure not to block the diffusion of the fog by a wall or an equipment.
    Set the chemical or biological indicators in the locations assumed to be the most difficult to reach.
    Stop the ventilation and close the doors.
    Launch the program remotely using the MyPhileas application: space volume, dose, number of cycles, delay time, contact time.
    Once the diffusion is completed and the contact time has elapsed, start aeration in the treated space: a renewal of 20 times the volume of air is usually recommended to reduce the concentration of H₂O₂ and return to the acceptable threshold to reuse the space (<1ppm).
    After aeration, gently collect the biological indicators and incubate them at 55°C for 7 days. Read the chemical indicators.

Good practices
  In between treatments, some last best practices to ensure optimal longevity of your Phileas®:
    Keep the protection cap on the disc and avoid handling it to keep it straight and functional.
    Perform preventive maintenance regularly.
    Rinse the circuits with water before a long period of inactivity (see the user manual).
    The body can be cleaned with a soft damp cloth.

灭菌分步指南
  进行生化消毒之前，必须先明确任务要求：
    降低生物负荷的目标程度是什么（log₁₀ 4、log₁₀ 5、log₁₀ 6）？
    （采样）指示器应置于何处？
    如何、采用哪些指标（化学指标、生物指标）核验生化消毒的效果？
    待处理的空间是否非常杂乱（例如：气闸中已置物的推车、BSC 中的设备等）？
    是否存在一个或多个需要同时进行生化消毒的区域？
  若想建立一个满足规格条件的消毒流程，Devea 团队可为您提供支持：他们可借助跨领域经验，善用在与用户开展多个项目过程中积累的专业知识为您节省时间。

消毒日
  在消毒日当天，一旦空间完成清洁，Phileas® 解决方案就可以快速、轻松地进行启动：
    将装满消毒剂容器的 Phileas® 设备放置在区域中心，确保气雾的扩散不会被墙壁或设备阻挡。
    将生化指标指示器放置在最难触达的位置；
    关闭通风系统并将门关闭；
    使用 MyPhileas 应用软件，远程启动程序：空间体积、剂量、循环次数、延迟时间、接触时间；
    扩散完成、接触时间结束后，开始对处理过的空间进行换气：通常建议置换消毒空间 20 倍的空气量，以降低 H₂O₂ 的浓度到可接受的阈值以重新使用空间（<1ppm）；
    换气后，动作轻缓地收集指示器，并在 55°C 下培养 7 天。读取化学指标。

良好实践
  在两次消毒处理之间，可采取一些持续性的最佳时间来确保 Phileas® 的最大使用寿命：
    将保护帽盖在碟片上，避免对其进行操作，以保持其平直、可用；
    定期进行预防性保养；
    在长时间闲置之前用水冲洗管路（请参阅用户手册）；
    可以用柔软的湿布清洁机身。
