STERIS Workshop: Important Elements of Cleaning Validation and Health-Based Exposure Limits

9 Nov 2022
9.30-11.00am SGT | Online

Hosted by:



Cleaning validation is the documented evidence that the cleaning procedure can effectively remove residue to an acceptable level to prevent cross-contamination. Having a validated cleaning program is of utmost importance to any GMP manufacturing facilities.

One of the critical steps in performing a successful cleaning validation is establishing the limits of residue that can remain on the surface being cleaned. Several factors can impact the selection and validation of these residual limits, such as product grouping, sampling technique, analytical methodology, and areas of non-uniform contamination. During the presentation, we will explore approaches to establish health-based exposure limits for cleaning validation by detailing the factors that are used in the limit calculation and then calculating the residue limits for a variety of dosage forms using accepted daily exposure (ADE) or permitted daily exposure (PDE) values.

This presentation highlights key elements of cleaning validation to enable a facility to stay compliant with current regulations with attention to setting health-based exposure limits.

The following topics will be discussed in detail during the presentation:

  • Latest guidelines and regulations on cleaning validation
  • Typical inspection findings and warning letters
  • Important elements of Cleaning Validation
  • Establishing health-based exposure limits
