Introduction
• SIP is a widely adopted method for the in-line sterilisation of processing equipment.
• The main advantage of SIP is reduction of aseptic connections and manipulations that might compromise the integrity of the downstream equipment.
• Likely to be applied more and more with isolator and RABS technology.

Guidance
• ISO 13408-5:2006
Specifies the general requirements for sterilisation
in place (SIP) applied to product contact surfaces of the equipment used in the manufacture of sterile health care products by aseptic processing and offers guidance on qualification, validation, operation and control.
It acknowledges that SIP can be achieved by using steam or other gaseous or liquid sterilising agents.
Specific guidance on steam sterilisation in place, which is the most common method used, is given in Annex A.

27-09-12
Key Points
• The most important issue to consider in establishing sterilisation-in-place technology is the design of the system(s) to ensure that they be able to successfully sterilise manufacturing equipment to the desired level of sterility assurance.

27-09-12
Key Points
The critical requirements associated with SIP include:
• Proper steam distribution,
• Noncondensable gases removal, and
• Continuous condensate elimination.
Facilitated by:
• Good engineering practices,
• Adequate piping design,
• Steam traps, Valves, and
• Monitoring instrumentation.

27-09-12
Key Points
Process and equipment characterisation
• A process flow diagram that outlines the processing equipment layout to be sterilised, including valve sequencing.
• Drainability of the system (e.g. slope of piping to ensure the complete removal of remaining liquid in the system).
Slide 14

27-09-12
Key Points
• Compatibility of materials of construction (e.g. pipes, tanks, valves, nozzles, filters, gaskets, sensors) with the sterilising agent, over the anticipated number of sterilisation cycles.
• Provisions for maintenance of sterility during and after completion of SIP (e.g. by elevated pressure).

27-09-12
Key Points
Filter Sterilisation
• Condensate drainage should be equipped at the lowest part of both the sterile side and the non-sterile side of each filter housing.
• Steam bleed(s) should be positioned, where necessary, in the part of housing that might cause air retention.
Slide 16
![Page 17: Validation and Control of SIP - HPRA](https://reader030.fdocuments.us/reader030/viewer/2022012713/61ac0e422bf9421fb06a9397/html5/thumbnails/17.jpg)
27-09-12
Key Points
Filter Sterilisation
• The pressure differential across the filter element at the operating temperature should not exceed the manufacturer's recommendations.
• Steam pressure and differential pressure should be monitored.
• Temperature should be measured downstream of the filter.
Slide 17
![Page 18: Validation and Control of SIP - HPRA](https://reader030.fdocuments.us/reader030/viewer/2022012713/61ac0e422bf9421fb06a9397/html5/thumbnails/18.jpg)
27-09-12
Key Points - Validation
Process parameters shall be adequate to ensure sterilisation of the equipment being subjected to SIP.
• Critical process parameters for steam SIP are time, temperature and steam pressure.
• Minimum and maximum limits should be specified and controlled throughout the sterilisation cycle.

27-09-12
Key Points - Validation
• Controlling and monitoring of the sterilisation conditions in the defined locations.

27-09-12
Key Points - Validation
• Biological indicators or inoculated carriers shall be used during the performance qualification. The number and locations of biological indicators shall be specified.
• Documented evidence shall be provided to show that the number and locations of biological indicators are sufficient to demonstrate that the requirements for SIP of the equipment have been met at locations presenting the greatest sterilisation challenge.

27-09-12
Key Points - Validation
• Performance qualification shall include a series of at least three consecutive and successful runs of the SIP process to demonstrate the reproducibility and effectiveness of the process.
• The successful SIP runs shall be determined by measurement of physical parameters and inactivation of biological indicators or inoculated carriers which shall demonstrate the required microbicidal effectiveness.
