Gowning is one of the most direct ways contamination enters or stays out of a cleanroom. Most of it comes from people, not the environment, and a breakdown in gowning protocol is rarely visible in the moment. It shows up later, in environmental monitoring trends or an audit finding.The difference between sterile and non-sterile gowning […]
USP 800 PPE Checklist for Hazardous Drug Handling
PPE failures in hazardous drug environments are rarely about the product. They happen when the right product is worn incorrectly, changed too late, or skipped entirely during lower-risk tasks that still carry exposure risk. USP 800 sets the standard for protecting personnel who handle hazardous drugs, and PPE is one of its most specific and […]
A Buyer’s Guide to Tyvek Suit vs Other Cleanroom Suits
Tyvek suits are one of the most commonly used options in controlled environments, but they’re not the only choice. In cleanroom environments, suit selection isn’t just about the material. It’s tied to your ISO classification, your gowning procedures, and how your team actually works inside the space day to day. This guide walks through how […]
Find Your Gaps in USP 800 Compliance
USP 800 officially went into effect on December 1, 2019. It is an excellent guide to protecting pharmacy techs, healthcare personnel, patients, cleanroom cleaning staff, and even our planet from contamination by hazardous drugs (HD). Earlier updates to USP 795 and USP 797 created some uncertainty around how USP 800 would be applied. Since both […]
How to Build a Cleanroom Monitoring Plan for ISO Compliance
Imagine this: your facility has operated comfortably within its ISO classification for years. Particle reports look acceptable at a glance. Then, during a routine review, your quality team notices a gradual upward trend near a high-traffic filling line. Nothing has technically failed, and no alarms were triggered. But the data reveals a pattern that wasn’t […]
Cleanroom ISO Classes & Standards: How to Choose the Right Disposable Cleanroom Supplies
ISO classifications shape nearly every decision made inside a cleanroom, but their impact is often misunderstood when it comes to disposable supplies. While particle limits define each class on paper, day-to-day contamination control depends heavily on what workers wear, touch, and discard during normal work. Disposable gloves, coveralls, masks, hoods, and boot covers form one […]
How to Conduct a Cleanroom Gowning Procedure Audit + Sample Checklist
Gowning is one of the few cleanroom controls that every operator interacts with daily. While that makes it an important barrier against contamination, it’s also a common source of variability. Even with well-documented SOPs, small “workarounds” or deviations can creep in over time and undermine compliance. A gowning audit gives you a structured way to […]
Double-Gloving and Layering Techniques for High-Risk Cleanroom Work
Single-layer gloves, even high-quality ones, have their limits. They can tear, degrade under chemical exposure, or allow microscopic contaminants to pass through. Double-gloving creates redundancy: if the outer glove fails, the inner glove continues to protect both the worker and the product. For example, during pharmaceutical compounding, an accidental spill of a solvent on the […]
Top 10 Key Factors for Cleaning and Maintaining a Controlled Cleanroom Environment According to USP 797
Designing and implementing a cleaning program for your cleanroom can seem daunting. Knowing where to begin or what to include can assist with maintaining the cleanroom long-term and help strengthen sterility assurance of the compounded sterile preparations (CSPs). In this article, we will discuss the top 10 key factors for developing an effective cleaning procedure […]
How to Stop Contamination Before It Starts with the Right Cleanroom Apparel
In cleanrooms, even the tiniest particle can affect product quality, worker safety, and regulatory compliance. For professionals in pharmaceuticals, biotech, semiconductor, or medical device facilities, preventing contamination starts with one of the simplest yet most essential tools: cleanroom apparel. Understanding how the right garments protect your facility, staff, and products is key to keeping your […]
Top 10 Pre-Saturated Cleanroom Wipes for Labs
Imagine this: a lab is in the middle of a critical experiment. Everything seems to be running smoothly. Samples are prepared, instruments calibrated, and researchers focused. Then, during a routine check, someone spots a tiny particle on a bench top. It seems harmless, but in a controlled lab, even a speck of dust can ruin […]
The Key to Using Sterile Face Masks Correctly in a Cleanroom
Maintaining a contamination-free cleanroom depends on many factors, and one of the most essential is proper use of sterile face masks. Sterile masks act as a barrier between personnel and sensitive products, protecting critical environments in industries like pharmaceuticals, biotech, and electronics manufacturing. Even a small misstep—touching the front of a mask, wearing it improperly, […]
