Please note, this webinar has been rescheduled from 13 June to 28 June. If you registered for the previous date and would still like to attend, please register again.

Part II of this webinar carries forward in the cleaning and sterilization “life cycle” of product contact equipment, focusing on sterility maintenance through wrapping, sterilization, transport, storage and aseptic presentation. We discuss potential contamination risks and mitigation solutions at each step of the life cycle.

Additionally, the webinar reviews terminal product sterilization using Vaporized Hydrogen Peroxide and how it meets requirements for repeatability and reliability.

To conclude, the webinar demonstrates best practices for achieving compliance with the revised regulation by defining the contamination risks and identifying appropriate controls for critical surfaces.
