Bellow are the Risk assessment report at different stages like dispensing, sifting, milling, wet granulation, drying, blending, compression and coating of tablet manufacturing process. The below risk is identified based on risk involved in the process but not limited to .

Function of camera in Blister Packing Machine :

The Color Camera System is to be attached on to the blister packing machine.  It is designed to detect and reject the defective blisters during blistering of the product.

It can inspect tablets or capsules (hard or soft gelatin) blistered in following types of material of construction with maximum blister dimension of 200 x 160 mm.

PVC or PVDC (Clear, Color or Opaque)

ALU/ALU

It can detect and reject the blisters having following defects:-

Broken tablets, damaged capsules

Partially or fully empty blister.

Blisters containing products of different size or shape.

Product having spots (which is not its specification)

Blisters containing foreign particles.

PERFORMANCE QUALIFICATION REPORT :

Performance is checked by performing the following tests.

Performed all the tests at 3 different speeds of blister packing machine and for the entire track and the details of the product used for performance qualification and observations shall be recorded in the following tables.

Minimum Speed, Optimum Speed and Maximum speed of Machine :

Product Name:                                                        Batch No.:        

Batch Size:                                                               Pack Size:

Sr. No.	Test	Test Procedure	Acceptance Criteria
1	Verification of rejection of blister without product (Completely empty)	Create the blisters without product and run the blister packing machine. Check whether empty blisters are rejected by system or not. Repeat for 3 times.	All empty blisters shall be rejected by the system.
2	Verification of rejection of one empty pocket.	Create blisters with missing product between two good blisters. That is one pocket should not have product. Check whether the same is rejected by system. Repeat for 3 times at 3 different positions for all the blisters in the track.	All blisters with missing product should be rejected by the system.
3	Verification of rejection of spots discoloration.	Create the spot on product with pen/marker. Place the product with spot facing towards camera in the blister and run the blister packing Machine. Check whether the product is rejected or not by system. Repeat for 3 times at 3 different positions for all the blisters in the track.	All blisters with products having spots should be rejected by the system.
4	Verification of rejection for broken units.	Insert broken product in a blister and run the blister packing machine. Check whether the product is rejected or not by system. Repeat for 3 times as approximately 10%, 25% and 50% breakage of product.% of broken tablet shall be done on weight basis. Take the weight of intact tablet and break the edges of the tablets to achieve required % breakage.	All blisters with broken product should be rejected by the system.

Sr. No.	Test	Test Procedure	Acceptance Criteria
5	Verification of rejection of object different colour.	Create the object of different colour of same product with methylene blue and run the blister packing machine. Check whether the product is rejected by system. Repeat for 3 times by placing the different product at 3 different positions in the blister.	All blisters with different colour product should be rejected by the system.
6	Verification of the effect of the changes in the tolerance value for the area and spot.	Set the tolerance value at 5 and check for spot on the tablet and 10% broken tablets. Check whether the product is rejected by system. Perform the test at different tolerance. i.e. 10 & 20.	All blisters with defective product should be rejected by the system.
7	Verification of the count i.e. no of packs between the camera and the punching tool for the rejection of the defected blister.	Enter the count for rejection between the camera and punching tool correctly.	Defected blister shall get rejected after punching.
8	Verification of the count for the rejected blisters during the packing.	Ensure the count for each type of rejection is zero. Run the machine with the different type of defects and collect the blisters after rejection separately as per the type of defect. Check whether the count shown in the screen matches with the collected rejection of the blister as per the type of defect or not.	The count for the rejected blisters of each type should match with the collected blisters after rejection.

3.2.1 The engineering stores personnel shall receive the FBD filter bag along with the party’s COA, regarding filter cloth used in FBD bag manufacturing and inform the production personnel about the receipt.

3.2.2 After receiving the information about the receipt from engineering stores, the production personnel shall check the party’s COA as per the specification.

3.2.3 The production personnel shall record the receipt and initiate for joint inspection of the FBD filter bag visually for absence of holes, foreign particles, fibres, stitching quality, bag diameter, finger diameter, finger length and number of fingers by the production personnel and QA personnel. 

3.2.4 Record the receipt and inspection of FBD filter bag.

3.2.5 After inspection, transfer the FBD filter bag to the washing area for washing, followed by drying.

Note: Do not store more than one FBD filter bag in a polythene bag.

3.3 USAGE:

3.3.1 Record the details of FBD filter bag usage, integrity checking (visually), cleaning and discarded dates.

NOTE:

1. Check the integrity of the FBD filter bag before and after use.

2. Incase of any damage to the FBD filter bag, discard that FBD filter         bag.
