Hygienic Process
PIP Hygienic Process Practices work across all PIP function teams, creating design, fabrication, and procurement guidance for both regulated and unregulated contaminant-sensitive processes.
PIP Hygienic Process Practices serve industries including Chemical, Food & Beverage, Consumer Products, Pharmaceutical, Semi-Conductor, and Pulp & Paper.
Areas include intermediaries and products subject to Current Good Manufacturing Practice (CGMP) or government inspection, safety, and efficacy requirements and products subject to stringent but unregulated clean design practices, including semi-conductor crystallization clean room design.
Why PIP Hygienic Process Practices?
Contaminant-sensitive processes are employed to manufacture much of what the public uses and consumes daily, from cosmetics, food and pharmaceuticals to electronics. Still, there are gaps in guidance for both regulated and unregulated hygienic processes within these areas.
PIP Vessels Practices fills these gaps, laying out the steps and considerations for piping, rotating equipment, machinery, structures and other intermediaries and the processes they require in certain hygienic applications.

Examples of Hygienic Processes
- Coatings & Insulation Specifications, Including the Application of External Coatings.
- Clean In Place (CIP) System Specification for a Packaged System.
- Clean Room Specification, Including Design Considerations and a Data Sheet.
- (Under Development) Pigging System to Specify and Source a Product Recovery System.

Covering the Bases in CIP, Clean Room, and Pigging Systems
The PIP Hygienic Practices team brings together CIP comprehensive practices, Clean Room specifications, and Pigging Systems to provide full-discipline practices for PIP members and outside companies. This harmonization, currently under development, is a unique way in which these three challenging areas can finally be addressed comprehensively.
