5.0 Frequency: 5.1 Initial Validation: Three (3) successful runs for all planned loads. 5.1.1 Shifting of the equipment from one location to another location. 5.1.2 If replacement of major components / Instruments. 5.1.3 Change in PLC programme. 5.2 Revalidation: One successful run once in a year for all loads at defined maximum load pattern. 6.0 Rationales for Validation Study: 6.1 Rationales for Probes quantity 6.1.1 Empty chamber Heat Distribution: In steam sterilization process steam is not flowing, only condensate formed in the chamber is purged out and the pressure in the chamber is maintained by further inlet of steam. Therefore uniform heat distribution is expected in the steam sterilizer chamber during sterilization hold period and probability of non-uniformity within the chamber is less. In the Autoclave steam inlet is from the both sides of the chamber through baffles, for uniform distribution of steam in the chamber. Condensate drain point is located at the bottom. Three horizontal planes of two shelves (i.e. top and bottom) are selected for temperature mapping. 4 probes to be placed in four corners of top shelves, 3 probes at corner &1 probe at centre of top selves. 3 probes at corner & 1 probe in drain point of lower shelves (attach layout) 6.1.2 Loaded chamber heat penetration: For sterilization of Rubber stoppers, Garment & Miscellaneous Load (Silicone tube) the 5 probes are placed inside the load, 1 probe in drain point and 4 probes in the chamber as per respective loading pattern diagram attached as Exhibits to this protocol for monitoring of heat penetration in loaded chamber.

Once the maximum and minimum load are validated for Autoclave at defined validated Load pattern need not to qualify periodically for minimum load. Therefore only maximum loads will be periodically revalidated at defined load pattern considering it as worst case scenario.

6.3 Functional Risk Assessment Function wise processes are listed and evaluated for assessment of risk to either product quality and data integrity. It involves mainly following steps. 1.

Identifying GMP Risk

2.

Identifying Risk Scenarios

3.

Assessing the likelihood of An Adverse Event

4.

Assessing the severity of impact

5.

Detection of adverse impact

6.

Overall priority

The above risk were prioritization of risk in High/Medium/Low categories. 6.4 Identifying GMP Risk System function parameters are evaluated and identified whether they represent a risk when assessed against a series of GMP criteria. Following types of risks are mainly identified during risk assessment process for qualification of system as below: · Risks towards non-availability of required documentation · Risks towards non-availability of required SOPs · Risks towards non-availability of system Access Control

· Risks towards abnormal user operation performed at the time of system operation · Risks towards incorrect configuration of system · Risks towards Improper and/or inadequate training 6.5 Identifying Risk Scenarios Having determined that a particular function may have a GMP risk associated with it, the assessment proceeds to identify the various risk scenarios i.e. the events that identify the risks associated with use of the system. The functions identified are analyzed by considering possible hazards/adverse effects and what controls may be needed to minimize the potential harm. 6.6 Assessing the Likelihood of An Adverse Event After identifying hazards / adverse events, determine the likelihood (frequency or probability) of it occurring. User considers the likelihood of the adverse event occurring per number of transactions, and assigns category as per estimation of risk. 6.7 Assessing the Severity of Impact After determining likelihood of adverse event, severity of its impact on process is assessed. These effects take into account impact on regulatory compliance, impact on product quality and impact on data integrity. The impact of risk occurring may be described as follows:

6.8 Ranking Of Adverse Event Severity Table – I Value 3

(S) Severity of Event (Consequence) High(H) : Can cause serious adverse health consequences which can threaten the life of Patient or even death

2

Medium(M) : Temporary or reversible adverse health consequences but the life of the patient is not threatened

1

Low(L) : No effect/Impact for patients

6.9 Detection of Adverse Event Next step is to identify if the adverse event can be recognized or detected by other means in the system. Adverse event having high probability of detection, may not pose a serious threat because it can be recognized quickly and suitable corrective action taken to mitigate its impact. If an adverse event has a low probability of detection, then the risk condition needs to seriously consider a review of the design or the implementation of alternative procedures to avoid the event. 6.10 Ranking Of Adverse Event Detection Table – II Value (D) Level of Detection 1 High (H): The risk can be easily detected through deployed control measure/system and the detection system is automated. 2 3

Medium (M): The risk can be detected later through deployed control measure/system and the detection is through manual method Low (L): The risk cannot be detected through deployed control measure/system the detection is possible after longer period/interval.

6.11 Risk Review and Monitor Controls After controls are implemented, they will be monitored for life cycle of the system. This will be part of performance monitoring of the system. Periodic review after the system is fully operational /validated shall a. Consider whether previously unrecognized risks are present b. Determine if previously identified hazards are still present ( and to what level) c. Ascertain if the estimated risk associated with a hazard is no longer acceptable d. Evaluate whether all existing controls are still necessary
