Introduction: Navigating the World of Cleanliness

The Biological and Pharmaceutical Manufacturing Industry operates under stringent conditions, demanding the highest standards of cleanliness and sterility. In this article, we delve into the clean rooms and laboratories that underpin this industry, exploring their characteristics, importance, and critical standards. Let’s embark on this journey to understand the vital role cleanliness plays in this field.

1. Features of Bio-Pharmaceutical Factories

Bio-pharmaceutical factories stand as the cornerstone of this industry, boasting impressive features:

1. Complexity and Costs: Equipped with high-cost machinery and intricate production processes, these facilities command substantial investments.
2. Stringent Sterility: Maintaining high levels of cleanliness and sterility is non-negotiable in these environments.
3. Quality Personnel: Strict requirements extend to production personnel, emphasizing the utmost precision and expertise.
4. Biological Hazards: Production processes pose biological risks, from infection to product toxicity, sensitization, and environmental impacts.

2. Clean Areas: Guardian Against Contaminants

Clean areas are pivotal components of this industry, controlling dust particles and microbial pollutants. Their purpose is to prevent the introduction, generation, and retention of pollutants within designated spaces.

3. Air Lock Rooms: Controlling the Flow

Air lock rooms, isolated spaces with multiple doors between rooms of varying cleanliness levels, are key to regulating airflow during personnel and material transitions. They come in two forms: personnel air lock rooms and material air lock rooms.

4. Cleanroom Levels in Bio-Pharmaceuticals

Cleanrooms in this sector adhere to specific cleanliness levels, categorized as partial 100, 1000, 10,000, and 30,000 under the backdrop of either 100 or 10,000.

• Temperature: Generally, clean rooms maintain temperatures between 18 and 26 degrees Celsius, with relative humidity ranging from 45% to 65%.

5. Pollution Control Strategies

Controlling pollution within clean pharmaceutical workshops revolves around source pollution control, spreading process control, and cross-contamination control. Of utmost concern are dust particles and microorganisms, the top priorities in environmental control.

6. Clean Room Challenges in GMP Transformation

During GMP (Good Manufacturing Practice) transformations, several challenges emerge:

• Misunderstanding of Clean Technology: Subjective perceptions can hinder effective pollution control, leading to substantial investments without significant improvements in product quality.
• Facility Control Procedures: Design, construction, equipment, raw materials, and facility management can collectively impact product quality.
• Construction-Related Risks: Problems during installation and construction may include air duct issues, improper sealing, dust accumulation, and more.
• Quality Control Measures: The quality of sealants, air duct check valves, drainage systems, clean room pressure settings, and adherence to production process requirements are critical factors.

7. Clean Laboratories: Exploring Two Categories

Clean laboratories are essential in the biological and pharmaceutical manufacturing industry, classified into two categories:

• Ordinary Clean Laboratories: Designed for non-infectious experiments, they must maintain an environment that doesn’t affect the experiments themselves.
• Biosafety Laboratories: Equipped with four protection levels (P1 to P4), biosafety laboratories are crucial for microbiology, biomedicine, genetic recombination, and more.

8. Levels of Biosafety Laboratories

• P1 Laboratory: Suited for less dangerous sources of disease, adhering to standard microbiological practices.
• P2 Laboratory: Designed for disease sources with moderate potential danger, requiring restricted access and safety cabinets for aerosol-related experiments.
• P3 Laboratory: Ideal for high-risk disease sources, featuring negative pressure, strict access control, and filtered air.
• P4 Laboratory: Reserved for extremely hazardous disease sources, with stringent safety measures including independent isolation, negative pressure, and protective gear.

9. Dynamic Isolation: Core of Biosafety Laboratories

Biosafety laboratory design prioritizes dynamic isolation, emphasizing measures such as on-site disinfection, clean/dirt diversion, and prevention of accidental spread. A moderate level of cleanliness is maintained.

Conclusion: The Pillars of Quality and Safety

Clean rooms and laboratories are the unsung heroes of the biological and pharmaceutical manufacturing industry. They ensure that quality and safety standards are met, safeguarding both products and personnel. In this high-stakes world, meticulous attention to cleanliness is not just a standard; it’s a necessity.
