12. What is meant by start up and shut down sequence?
Pressure cascades and appropriate air flow directions play an important role in containment. Therefore pressure cascades and air flow direction should be maintained as designed. In cases where AHUs are turned off (e.g. when cleaning or maintenance takes place), a pre-determined sequence of shutting down AHUs should be followed to ensure that there is no risk of contamination or cross contamination due to migration of dust from dirty to clean areas. (The principle also applies when staring AHUs).
