Location: Virtual | 6 - 7 p.m. GMT+8

This webinar focuses on environmental contamination control measures, including cleaning, decontamination, biodecontamination and disinfection as they relate to Annex 1 requirements.

We begin by identifying common contamination sources in cleanrooms and during production by walking through a generalized production process. Then, we present the elements to consider before designing contamination control measures for cleanrooms, material transfer, aseptic suites, critical utilities and process equipment.

The webinar includes a discussion of Vaporized Hydrogen Peroxide (VHP) as a decontamination modality in the Annex 1 framework. Finally, we review the risks associated with insufficient cleaning after implementing environmental disinfection measures, advising the manufacturer of a suitable set of controls to ensure effective contamination control.
