A specially constructed, environmentally controlled enclosed space with respect to airborne particulates, temperature, humidity, air pressure, air flow patterns, air motion, vibration, noise, viable ( living), organism and lighting.

Control of particulate and microbial contamination and control of particulate concentration and dispersion.

Design consideration :-

• Proper HVAC design.
• Proper construction of wall and ceiling.
• Installation of clean room light fittings.
• Suitable flooring.
• lintfree cloths for dress.

Regular monitoring and testing of a clean room only can maintain it's classification :-

• Monitoring includes differential pressure across the room.
• Air change of the room.
• Hepa filter integrity test.
• Particle counting.
• Recovery test.
• Temperature recording.
• Relative humidity recording.

Supporting Control :-

• Water piping.
• Dranage piping.

Laboratory Support :-

• Surface sampling.
• Settling plate.
• Slit sampling.
