| WHAT IS CLEAN ROOM ? |
| |
| Countless microscopic substance are suspended around you. In the dramatic development of electronic and precision machinery, their components have become miniaturized for better function. So even air-bone microscopic matters adversely affect the quality of in process products. |
| |
| The product of foodstuffs and pharmaceuticals requires an atmospere with much less contamination. Thus you need to set up clean rooms in which major production factor can be well controlled; air-bone microbial particulates, air temperature and humidity, air-flow rate and distribution, and so on. |
| INDUSTRIAL CLEAN ROOM (ICR) |
| |
| According to American Federal standard,a clean room is “a room in which the quantity of particles floating in the air and, when necessary ,the temperature,humidity,and pressure,can be controlled” The main objective of the Clean room is the control of dust,and the density of the dust in given room is determined according to the requirements of the products to be handled in the room.
|
| BIOLOGICALLY CLEAN ROOM (BCR) |
| |
| Unlike clean rooms, whose main aim is to control dust,the prime objective of the bio-clean room is the control of microorganisms. Germ-free operating theaters and wards fall into the category of biologically clean room
|
| BASIC PRINCIPLE OF CLEAN ROOM |
| |
| Not only visible dust but also invisible airborn ........ |
| ........ particles are kind of enemy for quality control. |
Not to bring any dust
1. No dust leakage from HEPA filters and frames.
2. To keep positive pressure in the rom.
3. Person to enter into the room after changing clothes and shoes and though air shower.
4. To being material and equipment into the room after cleaning.
|
 |
Not to generate any dust
1. Persons to wear dust-free garment.
2. Not to use any material or equipment which easily generate dust.
3. Not to move unneccessarily.
4. Not to bring disused articles.
|
To remove any dust quickly
1. To increase air-change rate.
2. To provide exhaust apparatus near the dust generating source.
3. To make appropriate air flow cleaning work.
4. Prevents dust adhesion on the products.
|
|
Not to accumulate any dust
1. Not to make any such corner or surrounding of equipment which makes cleaning works difficult.
2. To try not to expose duct or piping in the room.
3. To observe standardized routine cleaning work.
