However in ISO Class 5 or ISO Class 6 (or cleaner) clean rooms: coveralls, hoods, gloves, and shoe covers (also known as booties) are required. Precaution should be observed to assure that no sterile surfaces contact non-sterile surfaces during gowning, processing, or cleaning.Continue reading “Clean Room Gowning Procedure Step By Step” »
We begin by discussing the particle contamination issues in gown up rooms. Operating personnel enter gown up rooms to prepare for entry into the final clean room environment where items are processed. Without any static mitigating techniques, the operators and their clothing are statically charged causing substantial particle attraction.Continue reading “How to Reduce Particle Contamination via Ionization?” »
Every manufacturing environment contains some degree of airborne particles that can negatively impact your product or manufacturing process. These contaminating particles may already be present in the environment, or they may be introduced into your manufacturing area by people or things entering into that space.
Depending on the relative sensitivity of your product or process to those contaminants, you may require a clean room for your production. But just how clean a working environment do you require? The answer to that question is quite simply: “How many contaminants do you need to eliminate?”Continue reading “How To Select A Clean Room Classification Based On The Size Of Contaminants” »
