CLEAN ROOM SYSTEM IN STERIL PHARMA

WHAT IS A CLEAN ROOM?

It’s a closed environment where “clean” or “aseptic” work is carried out.It has a “regulated” atmosphere. It has low particle count with “predefined limits”. It is designed to generate less particles. It is designed to remove generated particles

Why Clean Room?

To protect the Product from contaminants
Head space is a portion of the Clean Room environment.

CONTAMINANTS:

What contaminants should be kept out?

Physical- dust, dirt, fibre, grit, glass, lint,
Chemical-  organic, inorganic, vapours, fumes, smoke
Biological- bacteria, fungi, virus, spores, pollen, endotoxins, human cells
Energies-  heat, light, sound, static, magnetic, electricity, radiation
Sources of contamination - All inputs to the “Clean Room” are sources of contamination
Material- RM, PM, lubricants, cleaning agents disinfectant
Machines- wear & tear of moving parts, rust, peel-off, emissions
People- sweat, breath, saliva, hair, cells,
Air- can bring in anything and everything imaginable
Facility-  shedding, wear & tear, breach
