Post Risk Assessment for Blister Packing Machine

1. Introduction for Post Risk Assessment for Blister Packing Machine:

The Post Risk Assessment for the Blister Packing Machine evaluates potential risks associated with the machine’s design, installation, operation, performance, and safety. The equipment is intended for packing tablets and capsules using printed aluminium foil with PVC, PVDC, or aluminium-based forming materials. The assessment follows the FMEA (Failure Mode and Effects Analysis) approach and considers severity, occurrence, and detectability to calculate the Risk Priority Number (RPN). The assessment covers risks related to design and installation qualification, calibration, equipment controls, alarms and interlocks, temperature sensors, recipe preparation, password protection, cleaning, feeding, sealing, coding, cutting, forming, camera systems, and safety guards. Appropriate existing controls and recommended actions are identified for each failure mode. The assessment helps confirm that identified risks are adequately controlled so the blister packing machine can consistently support product quality, safe operation, and reliable packaging performance throughout its lifecycle.

2. Flow Diagram for Post Risk Assessment process for the Blister Packing Machine:

The flow diagram explains the systematic Post Risk Assessment process for the Blister Packing Machine. It begins by defining the purpose and scope, followed by formation of a multidisciplinary team involving QA, Production, Engineering, QC, and Store. Required equipment information and reference documents are reviewed before identifying potential failure modes through FMEA. Each risk is evaluated using Severity, Occurrence, and Detection ratings to calculate the Risk Priority Number (RPN). Appropriate control measures are then implemented and responsibilities assigned. Risks are reassessed after actions, and additional controls are applied if required. Acceptable risks are documented, reviewed, approved, and formally closed.

8. Corrective Action and Preventive Action (CAPA) with Effectiveness Review:

Post Risk Assessment for Blister Packing Machine Not Done

The CAPA should address the identified gaps in planning, responsibility, training, documentation review, interdepartmental coordination, and QA oversight. The source document requires participation of QA, Engineering, Production, QC, and Store and uses FMEA for risk assessment.

No.	Identified Issue / Root Cause	Corrective Action	Preventive Action	Responsibility	Effectiveness Review
1	Post Risk Assessment not initiated on time	Prepare and execute the pending Post Risk Assessment immediately using FMEA.	Include post-risk assessment in the approved qualification/risk-management schedule.	QA / User Dept.	Verify completion and approval within the defined target date.
2	No defined assessment schedule	Prepare a documented timeline with responsibilities and completion dates.	Maintain a master tracker for all equipment risk assessments with periodic QA review.	QA	Review tracker after 30 and 90 days; no overdue assessment should remain.
3	Unclear responsibility and ownership	Nominate responsible personnel from QA, Production, Engineering, QC, and Store.	Define responsibilities in the applicable SOP or risk-management procedure.	QA Head	Confirm responsibilities are documented and understood during follow-up review.
4	Poor interdepartmental coordination	Conduct a cross-functional meeting and collect all required equipment information.	Establish scheduled cross-functional risk-review meetings.	QA / Engineering / Production	Verify meeting records and timely closure of assigned actions for three consecutive reviews.
5	Inadequate FMEA knowledge	Train concerned personnel on FMEA, Severity, Occurrence, Detection and RPN calculation.	Include Quality Risk Management/FMEA in the annual training program.	QA / Training Coordinator	Post-training assessment should demonstrate satisfactory understanding; review completed FMEA for calculation accuracy.
6	Incomplete document review	Review URS, DQ, IQ, OQ, manuals, drawings, calibration and supporting qualification documents before assessment.	Introduce a controlled checklist for document availability and verification.	QA / Engineering	Audit three subsequent assessments; required documents should be available and reviewed.
7	Weak QA follow-up	QA to review pending actions, recommended controls and residual risks before closure.	Introduce periodic QA review of open risk assessments and CAPAs.	QA	No overdue critical/major action during the defined effectiveness period.
8	CAPA/management review delay	Escalate overdue actions and obtain management review and approval.	Include risk-assessment status as a routine management-review agenda item.	Head-QA / Management	Verify timely review and closure during the next three management-review cycles.

Effectiveness Review

After implementation of the CAPA, QA should reassess the identified risks by reviewing Severity, Occurrence, Detectability and the revised RPN. The document specifically provides for review of the risk assessment after actions are taken and recording the resulting RPN.

Suggested effectiveness criteria: All planned actions are completed within target dates; trained personnel demonstrate adequate FMEA understanding; required qualification and reference documents are available; no post-risk assessment remains overdue; responsibilities are clearly assigned; and residual risks fall within the organization’s approved acceptance criteria. The source document classifies RPN ≥76 as critical, 51–75 as major, 26–50 as moderate, and up to 25 as minor.

The CAPA may be considered effective when follow-up confirms sustained compliance and the final risk assessment is reviewed, documented, and approved by the responsible departments and Head-QA.
