A controlled environment is designed to provide a clean space, free of contaminants that can potentially damage products or compromise a process. Classifications range from ISO 3/Class 1 to ISO 8/Class 100,000 and are determined by the number of particles allowed per volume of air.

The highest level, most stringent controlled environments are those that house the manufacturing and production of semiconductors, medical devices, and pharmaceutical products. These cleanrooms have strict regulations and guidelines that must be closely followed to preserve and maintain product quality.

The causes of contamination can vary, and if we look closely, it’s often traced back to unsuspecting sources. Supplies, materials, and equipment used in the cleanroom are common sources. People and their behaviors are another cause of contamination. Unsuspecting products that are needed in the cleanroom such as tape are a major concern because non-cleanroom rated product are typically used. Read on to see a variety of hidden causes of contamination within a controlled environment. Read more >
