What is the most common source of microbial contamination in pharmaceutical clean rooms?
people
There are four main sources of microbial contamination in cleanrooms and hospitals: people, surfaces and equipment, room air and room water (where applicable). Although humans are the main source, the contamination risk brought by the inert surfaces is not negligible.
What is a cleanroom microbiology?
A clean room is an environment where the levels of airborne contaminants are controlled to conform to specifications detailing the number, nature and size of the permitted particles. The air drawn into a clean room area is filtered and re-circulated through HEPA filters to control the level of particulates.
How can we reduce contamination in clean rooms?
How to keep cleanrooms free of contamination.
- Always Practice Good Hygiene. It’s estimated that 75-80% of contaminants or particles found during cleanroom inspections are produced by cleanroom personnel.
- Wear Required Protective Equipment Properly.
- Make Cleanroom Supplies Exclusive.
- Enter and Exit Cautiously.
- Limit Speaking.
How can we reduce contamination?

What are the clean room grade for Microbiology Laboratory?
A cGMP Grade A environment is equivalent to an ISO 5, for both at rest and in operation. This means that whether employees are working or not, the cleanliness inside the cleanroom must maintain Grade A levels (ISO 5).
What is clean area classification?
Cleanrooms are classified according to the number and size of particles permitted per volume of air. Large numbers like “class 100” or “class 1000” refer to FED-STD-209E, and denote the number of particles of size 0.5 μm or larger permitted per cubic foot of air.
Why can’t you wear makeup in a clean room?
Cosmetic particles not only are made up of contaminating chemicals, they could also compromise the sterility of a cleanroom. The first comprehensive study of these dangers appeared in an article entitled “Cosmetics in Clean Rooms” from the 1984 proceedings of the Institute of Environmental Sciences.

- Particulate matter (PM10 and PM2.
- Ozone (O3)
- Nitrogen dioxide (NO2)
- Carbon monoxide (CO)
- Sulphur dioxide (SO2)
What is particulate contamination in pharmaceutical industry?
Particulate contamination describes the unintended presence of extraneous, mobile and undissolved particles in a parenteral solution. 1,2. These particles can be of various size, defining them as detectable by visual inspection (in general ≥ 50 µm) sub-visible inspection with a range of 2-50 µm in size in general.
How can contamination be controlled in the workplace?
One of the easiest ways you can prevent chemicals from contaminating your workplace is by clearly labelling each substance. The labels should ideally include the name of the product, the expiry date and disposal methods, the dangers and clean-up instructions in case of an accident.
