Changing in to Cleanroom Garments

The best method of changing into cleanroom garments is one that minimises contamination getting onto the outside of the garments. One such method is described below. Some of the suggested procedures may be unnecessary in poorer classes of cleanrooms, and further procedures can be introduced in cleanrooms that manufacture products very susceptible to contamination. It should also be noted that alternatives to the proposed method are successfully used in existing cleanrooms, and these are quite acceptable as long as they give a level of contamination control appropriate to the standard of the cleanroom.

The design of clothing change areas is discussed in Chapter 5 where it is explained that the change area is normally divided into zones. These may be rooms, or rooms divided by crossover benches. Change areas can vary in design, but it is common to find them divided into three zones

1. Pre-change zone
2. Changing zone
3. Cleanroom entrance zone.
