Segregation and Filtering Variations
Once the principles of segregation and filtering are understood it is
possible to vary the strategy to suit special requirements.
For example, the clean zone does not have to be a single entity. As
shown in the figure below, you can create separate local clean zones.
Refer to the chapter Segregating Sources and Victims for guidelines on
crossing zones.
