- 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.
