Critical Environments in Advanced Nanoscale and Quantum Research Facilities
1 - 2:50 p.m. Central Time
Chair: Ahmad Soueid, HDR Architecture, Inc.

The nanotechnology program as IEST leverages the society’s well established and preeminent industry role in the areas of contamination control; design, test, and evaluation; and product reliability. IEST has taken many positive steps in addressing the challenges and considerations in planning facilities requiring critical environments by providing a focus on the IEST-RP-NANO program.  IEST-RP-NANO200 and NANO205 focused on planning and guidelines for Design, Construction, and Start-up as well as safety by applying prevention through design principles to nanotechnology facilities.  The soon to be released IEST-RP-NANO201 and NANO202 will focus on Measuring and Reporting Vibrations in Advanced Technology Facilities and Testing Aerosol-Nanomaterial Containment Devices.  

One of the objectives of the IEST-RP-NANO program is to develop Recommended Practices for categories of contamination best characterized as “energy contaminants” — specifically, vibration, acoustics, temperature stability, and electromagnetic effects, added to the already existing RP’s associated with electrostatic discharge (ESD), particulate contaminants and molecular contaminants. Energy contaminants affecting critical environments in advanced research and development facilities provide many challenges to facilities designers, builders and operators alike.  Due to the diversity of these contaminants and how they affect facilities dealing with emerging technologies, the industry lacks consensus regarding format, signal processing and units associated with assessment of these contaminants.  This conference session focuses on critical environments and how industry leaders solve these challenges.

GMP Annex 1
8 - 9:50 a.m. Central Time
Chair: Jim Polarine, STERIS

Annex I was updated and finalized this year in August. This session will focus on several key aspects of Annex I which include developing a Contamination Control Strategy, Environmental Monitoring, Bioburden and Particle control in cleanrooms, RABS, and Isolators. One of the key focuses of Annex I is to remove operators from the aseptic area by utilizing RABS and isolator technologies. The new Annex I is a concerted effort to move the industry forward in contamination control, rapid methods, environmental monitoring, cleaning and disinfection as well as newer technologies for isolating and preventing contamination during aseptic production. There are several new updated sections of Annex I which cleanroom facilities will need to become complaint with by August 2023.


  • EU GMP Annex 1 Changes and Impact to Sterilization of Product Contact Equipment - Renee Buthe, STERIS
  • A Roadmap to a Successful Contamination Control Strategy (CCS):  Covering Annex I Updates and FDA Warning Letters and 483’s - Jim Polarine, STERIS
  • Regulatory Audit Perspective of Cleanroom Disinfectant Qualification - Madison Hoal and Donald Singer, Ecolab Life Sciences

Cleanroom Microbiology
10:10 a.m. - 12 p.m. Central Time
Presenter: Ziva Abraham, Microrite

Microbiological control in medical products and medical products cleanrooms is a regulatory requirement to protect patients from harm. Understanding types of microbes, their sources, their methods of ingress, transport and proliferation within the cleanrooms and the challenges in disinfection and their clinical implications are some of the few ways to ensure microbiological contamination control.

Special Topics and Trends in the Industry
1 - 2:50 p.m.
Chair: Jim Polarine, STERIS

This session will focus on supply chain management, supply chain disruptions, the effects of the pandemic on labor shortages in the cleanroom industry, and business continuity. Contamination control and validation topics will also be included in this session. The special topics session will include presentations and topics that are cutting edge and not included in the other sessions this year at ESTECH.
