Organization, Personnel, Premises, Equipment & Raw Materials
This unit covers the operational infrastructure of pharmaceutical manufacturing under GMP. It addresses three critical areas: (1) Organization and Personnel — roles, responsibilities, training programs, personal hygiene, and health requirements. (2) Premises — design principles, plant layout, environmental monitoring, HVAC, clean room classification, and contamination control strategies. (3) Equipment and Raw Materials — selection criteria, purchase specifications, qualification, preventive maintenance, and storage of raw materials.
Syllabus & Topics
- 1Organization – Key Personnel: GMP requires defined organizational structure with qualified personnel. Key positions: (1) Head of Production: responsible for manufacturing operations, in-process controls, production records. Must be a qualified pharmacist (India: registered pharmacist under Pharmacy Act). (2) Head of Quality Control: responsible for approval/rejection of materials and products, analytical testing, stability programs. (3) Head of Quality Assurance: responsible for QMS, SOPs, audits, CAPA, change control, annual product review. (4) Authorized Person / Qualified Person (QP): in EU — responsible for batch release certification. These three heads must be INDEPENDENT of each other — no single person can be both Head of Production AND Head of QC.
- 2Personnel – Responsibilities & Training: Responsibilities: every employee must understand their job description, GMP requirements, and responsibilities. Training: (1) Induction training (at joining — organization overview, GMP basics, safety). (2) Job-specific training (SOPs for their area). (3) Continuing/refresher training (annual updates, new SOPs). (4) GMP training: ALL personnel, including cleaning staff, must receive GMP awareness training. Training records must be maintained (what, when, who trained, who was trained, assessment). Qualified trainers conduct training — documented with training effectiveness evaluation.
- 3Personnel – Hygiene & Health: Personal hygiene: (1) Clean protective clothing (gowning — coverall, cap, mask, shoe covers, gloves for production areas). (2) No eating, drinking, smoking, chewing in production/storage/QC areas. (3) Handwashing before entering production. (4) No cosmetics, jewelry in production areas. (5) Specific gowning procedures for sterile manufacturing (sterile gown, goggles, double gloves, boot covers). Health: medical examination at recruitment and periodically (annual). Employees with infectious diseases, open wounds, or skin conditions MUST NOT work in direct product contact areas. Pre-employment and annual health records maintained.
- 4Premises – Design Principles: Pharmaceutical premises must be designed to: (1) Prevent mix-ups and cross-contamination. (2) Allow logical flow of materials and personnel (unidirectional flow — raw material entry → production → packaging → finished goods — no backflow). (3) Be easy to clean and maintain. (4) Provide adequate lighting, ventilation, temperature, and humidity control. Plant layout: separate areas for — receiving/quarantine, sampling, approved storage, weighing/dispensing, manufacturing (separate rooms for different dosage forms), packaging (primary + secondary), QC laboratory, rejected materials, utilities (HVAC, water purification, compressed air). WHO/Schedule M requirements: adequate ceiling height (≥3 m), smooth walls/floors (no cracks — epoxy coated), rounded corners (easy cleaning), adequate drainage.
- 5Premises – Environmental Control & Sterile Areas: HVAC (Heating, Ventilation, Air Conditioning): critical for controlling temperature (20-25°C), humidity (45-55% RH), air quality (particulate and microbial). Clean room classification (ISO 14644 / EU GMP): Grade A (ISO 5): critical zone — high-risk operations (filling, open ampoules). Laminar airflow, <3,520 particles ≥0.5 μm/m³. Grade B (ISO 7): background for Grade A zone. Grade C (ISO 8): less critical steps. Grade D (ISO 8 at rest): least critical aseptic steps. HEPA filters (99.97% efficiency for 0.3 μm particles): mandatory for clean rooms. Air changes per hour: 20+ for Grade B, C. Pressure differentials: positive pressure cascade (cleanest area highest pressure) — prevents contaminated air from entering clean zones.
- 6Contamination Control: Cross-contamination: contamination of one product with another. Critical for: potent drugs (hormones, cytotoxics), penicillins (allergenic — DEDICATED facility required). Prevention: (1) Dedicated facilities for penicillins, hormones, cytotoxics. (2) Physical segregation (separate rooms, airlocks). (3) Pressure cascades. (4) Closed manufacturing systems. (5) Cleaning validation (demonstrate previous product residue removed below limits). (6) Campaign manufacturing (one product at a time). (7) Appropriate gowning. (8) Personnel flow control. Microbial contamination: controlled by HVAC (air quality), personnel gowning, cleaning/disinfection, environmental monitoring (settle plates, active air samplers, surface swabs). Water system: purified water, WFI (Water for Injection) — regular microbiological monitoring.
- 7Equipment – Selection & Qualification: Equipment selection criteria: (1) Suitable for intended operation. (2) Non-reactive material (SS 316L for product contact). (3) Designed for easy cleaning (no dead legs, smooth surfaces, CIP capable). (4) Meets GMP requirements. (5) Validated/qualified. Qualification (4 stages): DQ (Design Qualification): verify equipment design meets user requirements. IQ (Installation Qualification): verify equipment installed correctly per manufacturer specifications (utilities connected, calibration done). OQ (Operational Qualification): verify equipment operates correctly within specified parameters (empty runs, testing controls, alarms). PQ (Performance Qualification): verify equipment consistently performs as intended under actual production conditions (with product).
- 8Equipment – Maintenance & Raw Materials: Preventive maintenance: scheduled maintenance program to prevent equipment failures. Includes: cleaning, lubrication, calibration, part replacement. Maintenance SOPs and logbooks maintained for each equipment. Breakdown maintenance: unplanned — when equipment fails. Must be documented. Equipment logbook: records usage history, maintenance, calibration, cleaning, breakdowns — essential for GMP compliance. Raw materials: Purchase specifications: identity, purity, potency, particle size, moisture, microbial limits — based on pharmacopoeial/in-house standards. Vendor qualification: audit vendors, approve/reject based on quality history. Receiving: quarantine → sampling → testing by QC → approved/rejected → approved storage. Storage: FIFO/FEFO principle (First In First Out / First Expired First Out). Segregation: general, cold storage (2-8°C), controlled substances (locked), flammable solvents.

Exam Prep Questions
Q1. Why must penicillin manufacturing have a dedicated facility?
Penicillins are potent allergens — even trace amounts can cause severe allergic reactions (anaphylaxis, potentially fatal) in sensitized individuals. Cross-contamination of non-penicillin products with even ppm levels of penicillin is unacceptable. Therefore, GMP requires: COMPLETELY SEPARATE building, separate air handling system, separate equipment, separate personnel (ideally), separate utilities. This is one of the strictest cross-contamination requirements in pharma — also applies to cephalosporins, hormones, and cytotoxic drugs.
Q2. What is the difference between DQ, IQ, OQ, and PQ?
DQ: “Is the design suitable?” — verify equipment design meets User Requirement Specification (URS) before purchase.
IQ: “Is it installed correctly?” — verify installation per manufacturer specs (utilities, connections, calibration).
OQ: “Does it work correctly?” — test that all functions/controls/alarms work within specifications (without product).
PQ: “Does it produce quality product?” — run with actual product under production conditions → verify output meets specifications consistently.
Each stage must be completed and approved before progressing to the next.
Q3. What is FIFO and FEFO in raw material storage?
FIFO (First In First Out): materials received first are used first — prevents long storage of older materials.
FEFO (First Expired First Out): materials expiring soonest are used first — prevents use of expired materials.
FEFO is preferred for pharmaceutical raw materials because expiry date matters more than receipt date. Both principles require: proper labeling (receipt date, expiry, batch number), organized storage (newer materials behind older), and inventory management system (manual or computerized).
