• Seals on containers intact and verified

2. Visual Inspection of Containers:

• No damage, leakage, rust, or contamination observed
• Container type and integrity verified (drum, HDPE, bag, bottle, etc.)
• Inner liners intact and properly closed
• Proper labeling on all containers — Material Name, Batch No., Mfg/Exp. Date, Supplier Name
• Cross-check of number of containers received

3. Identification & Labeling:

• “UNDER TEST / TO BE QUARANTINED” label affixed on each container
• Material ID tag with details (Material name, Batch no., Quantity, Date received, Checked by)
• Containers segregated as per status tag color code (e.g., Yellow for Quarantine)
• Temporary identification labels intact until QA verification

4. Segregation & Handling:

• Raw materials, packaging materials, and intermediates segregated appropriately
• Rejected/damaged materials kept separately and labeled “REJECTED – HOLD”
• Sampling not initiated before QA authorization
• Handling equipment (trolley, pallet, forklift) clean and fit for use
• No cross-contamination risk between different materials/batches

5. Documentation & Recordkeeping:

• GRN (Goods Receipt Note) or material receiving form completed and signed
• Delivery challan/invoice attached to receiving record
• COA and test reports filed with the receiving batch record
• Material status updated in ERP/system
• Entry recorded in Material Receiving Log Book
• QA/warehouse supervisor sign-off for acceptance to quarantine

6. Environmental & Safety Checks:

• Staging area clean and ready before unloading
• Pest control and cleaning records available
• Environmental conditions (Temp/RH) within acceptable range
• Spill containment / safety equipment available
• PPE used by receiving personnel as per SOP
• No material directly placed on floor — all on pallets

7. Transfer to Quarantine Area:

• QA intimation sent for quarantine storage
• Material transferred as per defined flow path
• Pallets and trolleys sanitized before entry to quarantine
• Line clearance by QA/warehouse before and after transfer

RISK ASSESSMENT: Material Receiving at Staging Area (Before Quarantine)

Objective:
To identify and control potential risks associated with receiving raw and packaging materials at the staging area prior to quarantine — ensuring material integrity, traceability, and GMP compliance.

1. Scope:

This risk assessment covers all materials received at the staging area — including raw materials, packaging components, and intermediates — before being transferred to quarantine or sampling.

2. Reference Documents:

• WHO TRS 986 Annex 2 (GMP for APIs)
• Schedule M (Good Manufacturing Practices)
• ICH Q9 (Quality Risk Management)
• Internal SOP: Material Receipt and Quarantine Procedure

3. Risk Assessment Methodology:

Risk is evaluated using 6M (Man, Machine, Material, Method, Measurement, Environment) and the Severity–Occurrence–Detection (SOD) model.
Each risk is rated:

• Severity (S): 1–5
• Occurrence (O): 1–5
• Detection (D): 1–5
  → Risk Priority Number (RPN) = S × O × D

4. Risk Identification and Evaluation:

6M Factor	Potential Risk / Failure Mode	Possible Cause	Possible Consequence	S	O	D	RPN	Risk Level	Proposed Controls / Mitigation
Man	Improper verification of supplier documents	Inadequate training or attention	Wrong material accepted	4	3	2	24	Medium	Training on material verification, double-check by QA
Man	Material handling without PPE	Non-compliance to gowning SOP	Contamination risk	4	2	3	24	Medium	Gowning compliance audit, visual signage
Machine	Use of unclean trolley/pallet	Poor cleaning or lack of checklist	Cross-contamination	4	3	2	24	Medium	Cleaning log, visual tagging “Cleaned/Not Cleaned”
Machine	Calibration status not checked	Equipment misuse	Incorrect weighing or labeling	3	2	2	12	Low	Display calibration tag, preventive maintenance schedule
Material	Damaged or leaking container	Poor supplier handling	Contamination or mix-up	5	2	2	20	Medium	Visual inspection at receiving, reject damaged goods
Material	Missing or wrong label on container	Supplier error or human mistake	Mix-up or wrong identification	5	3	2	30	High	Verify label vs COA/PO, affix internal quarantine label immediately
Method	SOP not followed for receiving	Lack of adherence to procedures	Process non-compliance	4	3	2	24	Medium	SOP training, supervision during receipt
Method	Material placed directly on floor	Improper practice	Contamination from floor	4	3	3	36	High	Use pallets/racks, floor marking
Measurement	COA or data not verified	Incomplete documentation check	Incorrect batch release	5	2	2	20	Medium	QA verification prior to quarantine entry
Measurement	Material count mismatch	Manual error	Inventory discrepancy	3	3	2	18	Low	Double-check count, barcode or ERP entry
Environment	Area not clean / pest presence	Poor housekeeping	Contamination risk	5	2	2	20	Medium	Cleaning schedule, pest control record
Environment	Temperature not controlled	HVAC malfunction	Material degradation	5	2	3	30	High	Temp. monitoring system, alarms, calibration logs

5. Risk Evaluation Summary:

RPN Range	Risk Level	Action Required
1–15	Low	Acceptable; maintain control
16–30	Medium	Monitor and improve controls
>30	High	Immediate CAPA and preventive measures

6. Recommended CAPA / Mitigation Plan:

1. Implement 5S and visual control in staging area for segregation.
2. Train warehouse & QA staff on material receiving and quarantine SOPs.
3. Maintain trolley/pallet cleaning log before each receipt.
4. Introduce barcode verification or ERP-based label scanning.
5. QA verification checklist for document and physical inspection.
6. Temperature monitoring & alarm system for staging area.
7. Periodic internal audit for material receipt and quarantine flow.

7. Residual Risk Evaluation:

After mitigation, risks are expected to be reduced to Low or Acceptable level. Continuous monitoring should be done through internal audits and deviation trending.

8. Conclusion:

The risk assessment for material receiving activities at the staging area prior to quarantine has been conducted using the 6M approach (Man, Machine, Material, Method, Measurement, and Environment) and evaluated through the Severity–Occurrence–Detection (SOD) model.

All identified risks were analyzed for potential impact on product quality, safety, and data integrity. The assessment revealed that most risks fall within the low to medium category, with a few high-risk scenarios related to:

• Improper material labeling or documentation errors,
• Materials placed directly on the floor, and
• Environmental condition deviations (e.g., temperature excursions).

Appropriate Corrective and Preventive Actions (CAPA) have been proposed — including enhanced visual controls, staff training, cleaning verification, and environmental monitoring — to minimize these risks.

After implementation of these controls, the residual risk level is deemed acceptable and within the organization’s quality risk tolerance as per ICH Q9 and Schedule M guidelines.

Continuous monitoring, internal audits, and periodic review of the staging area operations will ensure that the control measures remain effective and that GMP compliance is consistently maintained.
