5 Tips For Keeping Contaminants Out of Your Cleanroom

It can be difficult to keep contaminants out of the manufacturing process. When your product depends on a highly controlled manufacturing area it is especially important to ensure the proper processes. As products become smaller and more sensitive to dust, vapors, and other airborne particles, the use of cleanrooms and clean manufacturing operations becomes more important. In these environments, the maintenance challenge is to increase cleanliness, minimize contamination, and keep equipment running. That challenge requires using materials, tools, and processes that will not affect the cleanliness of the finished product.

 

The four main sources of contamination in cleanrooms or clean manufacturing are: environment, process, tools, and people. Cleanliness levels vary, based on customer needs, but operating costs are directly proportional to the level of cleanliness required. These 5 tips can help you increase the effectiveness of your cleanroom and help control unnecessary costs due to lost time and/or product.

  1. Environment – Adjust for seasonal changes. Following OEM (Original Equipment Manufacturer) recommendations on filter and Deionized water changes is normal procedure. But in the spring and fall filters must be changed more frequently to offset increased outdoor particle counts caused by such natural occurrences as airborne pollen and water contaminated with leaves and algae.
  2. Process – Encourage routine preventive maintenance. Every few hours, all cleanroom operators should monitor their own workstations with a surface particle counter for contamination. If particle counts are high, they should immediately wipe down all surface areas and determine the particulate source.
  3. Tools – Dedicate cleanroom tools and equipment. Keep one set of tools and test equipment inside the cleanroom. This approach saves the time and aggravation of having to clean tools before bringing them into the cleanroom and the danger of cleanroom contamination caused by someone in a hurry.
  4. People – Train your staff. Anyone who might enter the cleanroom must understand the importance of proper cleanroom protocol. They must be shown how a “quick trip” to the cleanroom without proper attire to retrieve a forgotten tool, for example, releases millions of particles, requires immediate full-scale cleaning, and could downgrade cleanroom classification.
  5. Partners – Working with a commercial cleaning company who has cleanroom expertise and a commitment to quality assurance is your #1 defense against costly contaminants.
