Cleanroom gowning is the term used for putting on specialized coveralls or personal protective equipment (PPE) to minimize contamination in a cleanroom environment. Cleanrooms are highly controlled spaces found in various industries, such as pharmaceuticals, biotechnology, electronics, and medical device manufacturing, where cleanliness and sterility are of utmost importance.

The primary purpose of cleanroom gowning is to ensure that personnel working in these environments do not contribute to the contamination levels inside the cleanroom. Cleanroom gowning protocol involves following a specific order of donning the garments to ensure maximum protection and minimize the risk of contamination.

In this blog post, we will walk you through the step-by-step process of scrubbing into a cleanroom effectively using two different methods. Before following either of these methods, you should enter the designated area adjacent to the cleanroom, often known as a gowning room or gowning area, to remove any outer clothing, including jewelry and watches, that could potentially shed particles into the environment. 

Careful Cleanroom Gowning 

1. Clean & Sanitize Hands

Before you start scrubbing into a clean room, it’s essential to prioritize hand hygiene. Clean, sanitized hands are the foundation for maintaining a sterile environment. You should thoroughly wash your hands following the recommended guidelines, ensuring the elimination of potential contaminants. 

2. Careful Gown Handling

When opening your cleaning gown package, take the utmost care to minimize contact with any potential contaminants. Wearing cleanroom gloves can provide an additional layer of protection to help with this. You should also consider disinfecting your gloves after opening the package to further enhance the cleanliness of your gown and minimize contamination risks. 

3. Putting on the Gown

Cleanroom gowning requires a meticulous approach to minimize contamination. Avoid touching undergarments, furniture, or the floor as you don your cleanroom gown. Focus on maintaining control over the gown throughout the process. Once you have it on, ensure the gown is aligned correctly and covers all critical areas properly.

4. Pay Attention to Detail

Pay special attention to the sleeves and legs of your gown, as they are particularly vulnerable to contamination. You can use techniques such as the “overall origami” method to ensure a proper fit and complete coverage. This technique involves folding and controlling the gown carefully, minimizing the risk of contaminants coming into contact with critical areas. 

Controlled Cleanroom Gowning

1. Controlled Touching of the Gown

In this method, adopt a controlled approach when touching your cleanroom gown. Roll the gown while maintaining contact only with the outside until you reach the head of the belt. This method reduces the risk of contaminating the inside of the gown. 

2. Sleeve and Leg Management

You should maintain a high level of control over the sleeves and legs as you put on your cleanroom gown to prevent contamination. Be mindful when dropping the legs of the gown into boots, ensuring no contaminants are introduced. Attention to detail in this step is crucial for preserving the cleanliness of the gown. 

3. Neck Closure

Closing the neck of the gown securely is essential for maintaining cleanliness in your cleanroom environment. Use an appropriate technique to ensure a snug fit without compromising comfort or movement. If you have assistance, it is best for someone else to do this step. This step acts as a barrier against contaminants, preventing their entry into the gown. 

Tips for Successful Cleanroom Gowning

Scrubbing into a cleanroom demands precision, caution, and adherence to proper techniques. Below are some more tips on how to ensure your cleanroom garments maintain a high level of cleanliness during your gowning process.

Adhere to Cleanroom-Specific Procedures

Depending on the cleanroom environment, you may have other best practices to follow for proper cleanroom gowning. Familiarize yourself with the gowning procedures specific to your cleanroom. Each cleanroom may have variations and requirements that should be followed diligently. By understanding and adhering to these cleanroom protocols and procedures, you ensure consistency and maintain the integrity of the cleanroom environment. 

Minimize Unnecessary Touching

Throughout the cleanroom gowning process, be mindful of unnecessary surface contact, touching your face, or coming into contact with any potential contaminants. These precautions help uphold a sterile environment and minimize the risk of introducing contaminants. 

Take Time and Focus on Technique

Cleanroom gowning should never be rushed. Dedicate plenty of time to each step of your gowning process and maintain focus on executing the techniques accurately. Attention to detail is crucial for maintaining cleanliness within the cleanroom environment. By taking the time to gown properly, you contribute to the overall integrity of the cleanroom. 

Regular Training and Practice

You should maintain and improve your cleanroom gowning procedure through regular training and practice. By actively practicing, you ensure consistency and adherence to cleanroom standards. Continuous training fosters a culture of cleanliness and helps prevent deviations that may compromise your cleanroom environment.
