Can modular clean rooms Be Relocated?

Introduction to Modular Clean Rooms

Modular clean rooms have gained popularity in various industries due to their flexibility and efficiency. These structures are designed to meet specific cleanliness standards, such as ISO 14644, which classifies clean rooms based on particle concentration levels. This classification ranges from ISO1 to ISO9, allowing adaptation to different operational needs.

Advantages of Relocating Modular Clean Rooms

One significant advantage of modular clean rooms is their portability. Unlike traditional clean rooms, which are fixed structures, modular cleanroom designs can be disassembled and relocated with relative ease. This flexibility is crucial in industries like pharmaceuticals, where production demands may shift, necessitating the relocation of clean room facilities.

Factors Affecting Relocation

The relocation process involves several factors, including site preparation, compliance with local regulations, and revalidation of cleanliness levels. According to ISO 14644-3, revalidation must ensure that the clean room meets the required standards after relocation, including air cleanliness and environmental monitoring.

Cost Implications of Relocation

Relocating a modular clean room can be cost-effective compared to constructing a new facility. The total cost of relocation typically ranges from 20% to 30% of the price of a new clean room. This includes disassembly, transportation, reassembly, and compliance checks, which can be completed within a few weeks, minimizing downtime.

Compliance and Validation Post-Relocation

Once relocated, the clean room must undergo rigorous validation procedures to ensure compliance with relevant standards. This includes air particle testing, airflow assessments, and surface contamination checks. iso 14644-1 provides guidelines for these assessments, ensuring the clean room continues to meet operational requirements.

Relevant Standards and Regulations

• ISO 14644-1: Classification of air cleanliness.

• ISO 14644-3: Testing and monitoring to prove continued compliance.

• GMP Guidelines: Good Manufacturing Practices for clean room operations.

• ISO 9001: Quality management systems standards applicable to clean room processes. 

What Are the Basic Clean Room Requirements?

1. Air Cleanliness Levels

Clean rooms must adhere to specific air cleanliness levels defined by standards such as ISO 14644. These levels range from ISO 1 to Class 9, determined by allowable particle counts in the air.

2. Temperature and Humidity Control

Temperature and humidity must be tightly controlled to maintain product integrity and prevent contamination. Typical clean room conditions require temperatures between 20°C to 24°C and Relative humidity levels below 60%.

3. Filtration Systems

High-efficiency particulate air (HEPA) filters or ultra-low penetration air (ULPA) filters are essential for maintaining air purity. These filters can remove particles as small as 0.3 microns, ensuring that the air quality meets required standards.

4. Clean Room Protocols

Strict protocols for gowning, equipment use, and material transfer must be established. Personnel should follow these protocols to minimize contamination risks, including wearing appropriate cleanroom garments and following cleanroom behavior guidelines.

How Are Clean Rooms Constructed?

1. Design and Planning: The construction of modular clean room begins with careful design and planning. Factors such as the intended use, cleanliness requirements, and layout are considered to create an efficient space tailored to specific needs.

2. Structural Materials: The walls, ceilings, and floors of clean rooms are constructed using non-porous, easy-to-clean materials. Common materials include stainless steel, fiberglass-reinforced plastic, and vinyl flooring, which help maintain hygiene and cleanliness standards.

3. Airflow Systems: Airflow systems are critical in clean room construction. A well-designed HVAC system ensures proper air circulation, pressure differentials, and temperature control, while maintaining the required cleanliness levels throughout the space.

What Are the OSHA Requirements for Clean Rooms?

• General Duty Clause

Under the General Duty Clause, employers must provide a safe working environment. This includes maintaining clean rooms that meet specific health and safety standards to protect employees from hazards.

• Hazard Communication Standards

OSHA requires proper labeling and Safety Data Sheets (SDS) for chemicals used in clean rooms. This ensures that employees are informed about potential hazards and can handle materials safely.

• Monitoring and Recordkeeping

Employers are required to monitor the work environment and maintain records of safety measures. This includes documenting air quality tests and incidents to ensure compliance with OSHA regulations and improve workplace safety.

What Is the Occupancy of a Clean Room?

1. Density Limits

Occupancy density is a critical factor in clean room design. Higher occupancy can lead to increased particle generation, so many clean rooms limit personnel to ensure that air cleanliness standards are maintained.

2. Shift Management

Effective shift management is essential for maintaining clean room occupancy. By scheduling personnel appropriately, facilities can minimize the number of workers present while ensuring operational efficiency and cleanliness.

3. Impact on Clean Room Operations

The number of occupants can affect clean room operations significantly. Increased occupancy may require enhanced ventilation and filtration systems to maintain air quality, necessitating a careful balance between staffing needs and cleanliness requirements.
