Calculations show the predicted contamination levels in cleanrooms with turbulent mixing air and with vertical unidirectional airflow when people are dressed in modern cleanroom clothing systems. Comparisons are made between operation theatres and cleanrooms.

Study results show that the state of a cleanroom clothing system–new or much used–influences the protection efficacy of the system.

The limitation-of-risks (LR) method can be used as an engineering tool in risk assessment work for the identification, minimization, and evaluation of potential airborne risks, and for the identification of adequate monitoring points.
