摘要:
Today’s user is often faced with the challenge of meeting severalinternational standards and regulatory guidances as well asperforming sampling for airborne particles in a consistent andreproducible manner.
Internationalstandards for the monitoring of airborne particles are used by allindustries that employ cleanrooms or clean zones. Some form ofairborne sampling for particles is needed for these controlledenvironments in order to assure the quality of the product beingmanufactured or the success of the process that is being conductedin this controlled or critical environment. Many variables willaffect the success of the operations in these areas but theparticulate levels in the air are often a significant element inthe control of risk, or, inversely, the likelihood of success forthe controlled operation.
Today’s environments—especially asepticfilling operations but also mini-environments and other specialtyprocesses in electronics and aerospace—require consistent andreproducible results. The new calibration standards and recommendedpractices help with assuring the functionality of the particlecounter but there needs to be a significant focus on the samplingmethods and practices so that high quality data is obtained, andalso so that the act of obtaining the sample does not compromisethe process or product in the key areas.
Dynamic smoke studies can be extremelyvaluable to determine if the combination of airflow and activitywill result in risky patterns of flow that could draw contaminationinto the critical zones. The potential value of high flow particlecounters needs to be carefully weighed against the heightened riskof influencing airflow patterns. Perhaps new procedures need to bedesigned and implemented in your facility after reviewing smokestudies in order to maintain the quality and consistency of the airenvironment during activity.
