The Cleanroom Wiper Usage Audit
Cost reduction is no longer just a part of the overall continuous program; it is the critical requirement for survival.
Cleanroom Tip
Green Cleaning - Consider the cleaning process, not just the cleaning agent
You cannot be green and you cannot assure the safety of the worker based on selecting a supposedly safe and/or green cleaning agent. A supposedly green cleaning process that puts a high proportion of your product in the landfill may not be green for your purposes.
Cleanroom Tip
The Value of 3rd Party Certification
Once you have your cleanroom constructed, the HVAC system balanced, and the room(s) precision cleaned, your cleanroom is now ready to be certified to the classification of cleanliness it was designed to.
Cleanroom Tip
Gowning Practices
Proper gowning and gowning procedures reduce, but do not eliminate person-generated particles.
Cleanroom Tip
Controlling Cavitation Energy
In almost all cleaning applications, it is important to control the cavitation energy. When an insufficient amount of cavitation energy is provided, undesirably long process times may be required to obtain a desired level of cleaning, or in some cases, a desired level of surface cleaning may not be achievable.

Establishing and Implementing an Environmental Monitoring Program for Non-Sterile Operations
There are several positive advantages of establishing and implementing an environmental monitoring program.
Cleanroom Tip
Keep Product Clean In and Out of the Cleanroom
The first step in developing an effective precision cleaning process for the product is to determine where cleaning can be avoided. Keeping the product clean, particularly during transfer and storage, is an important part of your contamination control program.
Cleanroom Tip
Keep the Product Clean
Paperwork, raw materials for manufacturing the product, tools, and equipment must be successfully transferred to the cleanroom. The goal of a materials transfer program is to keep contamination from the outside world from entering the cleanroom.
Cleanroom Tip
Cleaning Protocol Training
Training, based on written protocols, is essential for proper cleaning of a cleanroom.Cleanroom personnel should have a good understanding of how and what they are to clean and why. They will perform much better if they know what they are expected to do.
Cleanroom Tip
How does the customer understand cleanroom wiper data?
How then does the customer understand the cleanroom wiper data presented and the degree of comparability between data presented by cleanroom wiper manufacturers?
Let's begin with a basic primer on the critical wiper data reported by most cleanroom wiper manufacturers in product data/information sheets:

Converting From an Uncontrolled Space to a Cleanroom
We are shifting our focus to manufacturing in a certified ISO Class 8 environment. We are converting a controlled manufacturing area into soft wall cleanroom with fan filter units providing the HEPA filtered air for the cleanroom. Where do I find information about cleaning of this cleanroom area, what garments our operators must wear, and personnel behavior while working in this new cleanroom?
Cleanroom Tip
Designing and Building a Cleanroom
I recommend the entire team review the Institute of Environmental Science and Technology recommended practice IEST-RP-CC 012.2, “Considerations in Cleanroom Design” as well as ISO 14644-4, “Cleanrooms and associated controlled environments – Part 4: Design, Construction and Start-up” prior to designing and building a cleanroom.
Cleanroom Tip
User-Friendly Operator Interface Systems
In the past, ergonomics have not been a prime consideration for industrial designs. But, when industrial engineers and designers omit ergonomics from their plans, they compromise the safe and efficient operation of equipment in controlled environments.
Cleanroom Tip
Identifying Genus and Species—Why Is It Important?
The identification of bacteria and fungi isolated from controlled environments ranging from Class 100,000 to sterility suits of Class 100 or less is accomplished biochemically by methods briefly set forth in USP and in greater detail by other methods.

Achieving True EH&S in Controlled Environments
What most organizations require is corporate-level, stringent process control. Beyond the perennial concerns of profitability and competitive advantage, life science organizations have a number of responsibilities to carefully consider each day in the area of environmental health and safety .
Cleanroom Tip
Effective Use of Alcohol Hand Sanitizers
Eliminating the risk of cross-contamination in pharmaceutical production areas, R&D labs, cleanrooms, and support areas includes effective methods for hand sanitization.

Learn How to Make Lean Manufacturing Work for You
Originated by Taiichi Ohno to analyze processes within the Toyota Production System, Lean principles have evolved into a development philosophy that strives to identify and eliminate waste by concentrating on what is valuable to the customer.
Cleanroom Tip
Maintaining Nano-Safety
Although nanomanufacturing is resulting in better, state-of-the-art products, it is still filled with a lot of unknowns, especially regarding exposure and worker safety.
Cleanroom Tip
Choosing a Green Fume Exhaust System
Facility and purchasing managers in the semiconductor industry have an excellent opportunity to leverage their technical knowledge, evaluate and prioritize initiatives, and pursue their final selection of a fume exhaust duct system that promotes and produces green rewards.
Cleanroom Tip
Exhausting Your Options
Semiconductor industry facilities and purchasing managers who are key decision makers for systems and materials selection need to rethink and broaden their approach in selecting, specifying, and purchasing an industrial fume exhaust duct system.
Cleanroom Tip
Cleanroom Consumable Cleanliness
My primary references for testing and evaluation of cleanroom consumable products has been the IEST (Institute of Environmental Science and Technology) recommended practices.
Cleanroom Tip
Wipe Specifications
With hundreds of choices and grades, selecting the most cost-effective wipe can be tricky. The most obvious criteria is the absorbency of the wipe. But, it is not well understood that absorbency varies by the contamination.
Cleanroom Tip
Capture-Only Technology
Almost all current filtration technologies are evaluated on the concept of “capture” rate, measuring the amount of particulates captured on the first pass through the filtration device. The higher the efficiency of a filtration device, the greater the number of particles captured.
Cleanroom Tip
Fact: All Humidity Sensors Drift
It’s an immutable law of RH measurement; relative humidity sensors drift. They do so for the simple reason that they are “air breathers.” Both fluctuating temperatures and contaminants significantly affect the accuracy of any RH sensor, more so over time.
Cleanroom Tip
The Challenge of Modeling Diffusers
Computation fluid dynamics (CFD) modeling provides the ability to accurately model air flow and heat transfer within a building, enabling heating and cooling systems to be optimized in a software prototype without the expense and time involved in making changes to the actual building.
