Introduction:
This quiz collection focuses on the essential requirements for site selection and facility design in the pharmaceutical industry, tailored for M.Pharm students specializing in Quality Control & Quality Assurance. Topics covered include regulatory expectations (such as Schedule M and international GMP), layout principles to prevent cross-contamination, cleanroom classifications and airflow strategies, utilities (WFI, compressed air, HVAC), material and personnel flow, waste handling, and validation/qualification stages. These questions are designed to deepen conceptual understanding and application of standards when planning or auditing pharmaceutical manufacturing facilities. Use this set to test knowledge, prepare for viva/exams, and reinforce best practices for compliant, efficient, and contamination-controlled facility design.

Correct Answer: Production cleanrooms for sterile product manufacturing
Q8. What is a key design principle for storage and distribution of Water for Injection (WFI) in a pharmaceutical facility?
- Use of a continuous loop circulating stainless steel system to avoid stagnation
- Storage in open tanks at ambient temperature
- Routing through painted carbon steel piping without insulation
- Intermittent batch storage in plastic drums
Correct Answer: Use of a continuous loop circulating stainless steel system to avoid stagnation
Q9. Compressed air used where it may contact product should be which of the following?
- Oil-lubricated with no filtration
- Oil-free, properly filtered and monitored for contaminants
- Ambient workshop air piped directly
- Only filtered for particles larger than 10 micrometers
Correct Answer: Oil-free, properly filtered and monitored for contaminants
Q10. What is the preferred direction of material flow inside a GMP facility to reduce contamination risk?
- From finished goods back to raw material storage
- From raw materials to intermediates to finished products, with separate dirty and clean flows
- Random movement according to convenience
- Materials flow combined with personnel traffic in the same corridors
Correct Answer: From raw materials to intermediates to finished products, with separate dirty and clean flows
Q11. Airlocks (vestibules) in a cleanroom system primarily serve to:
- Provide space for lunch breaks inside the controlled area
- Prevent particle ingress and maintain pressure differentials between zones
- Store excess equipment temporarily
- Allow direct external access for delivery trucks
Correct Answer: Prevent particle ingress and maintain pressure differentials between zones
Q12. Which gowning sequence is appropriate when entering a Grade A/B sterile area from a corridor?
- Put on gloves, then gown, then perform hand hygiene
- Hand hygiene → put on shoe covers → don gown → don mask and gloves
- Don mask only and enter
- Don gown outside, then perform hand hygiene after entering
Correct Answer: Hand hygiene → put on shoe covers → don gown → don mask and gloves
Q13. What is the correct sequence of qualification phases for a new facility or system?
- IQ → DQ → PQ → OQ
- DQ → IQ → OQ → PQ
- OQ → PQ → IQ → DQ
- PQ → IQ → DQ → OQ
Correct Answer: DQ → IQ → OQ → PQ
Q14. Which approach is essential for handling process effluents and hazardous waste from a drug facility?
- Combined discharge to municipal drains without treatment
- Segregated waste streams with containment and appropriate neutralization or treatment
- Dumping into onsite open pits
- Allowing evaporation in uncovered tanks
Correct Answer: Segregated waste streams with containment and appropriate neutralization or treatment
Q15. Surfaces and finishes inside production and cleanroom areas should be:
- Porous and rough to hide wear
- Smooth, non-shedding, corrosion-resistant and easily cleanable
- Painted with standard household paint
- Textured to provide grip and trap particles
Correct Answer: Smooth, non-shedding, corrosion-resistant and easily cleanable
Q16. What is the primary function of a buffer/change room between a general corridor and a clean manufacturing area?
- Provide storage for finished goods awaiting shipment
- Act as a controlled transition zone for gowning and to reduce contamination risk
- Host administrative meetings near production
- Serve as a chemical storage for raw solvents
Correct Answer: Act as a controlled transition zone for gowning and to reduce contamination risk
Q17. Which of the following is NOT typically a primary design objective for HVAC systems in pharmaceutical cleanrooms?
