  1. PM tasks should be defined in an SOP. If using a vendor to do the work include a generalized protocol as an attachment to the document.
  2. PM’s should use a proactive process that monitors the “Health” of the unit, not just a process that only looks at physical issues such as door seals, chamber lights, etc.
  3. Maintenance should be discussed and classified as Scheduled (PM) and Non Scheduled (breakdown).
  4. Defining the requirements is the responsibility of both Chamber Ops and Facilities. Controlled by Stability/Quality
  5. Work needs to be completed in a cGMP process
  6. Original documentation should be recorded and filed for all work in a filing program that is quickly accessible and references only the specific unit. The SOP should include a form for the documentation of work.
