Best Practices for Cleanroom Cleaning and Sterilization

Certain processes require an impeccable atmosphere to avoid adverse effects and anomalies. To help create a stable environment and eliminate potential problems, many industries use cleanrooms. Cleanrooms are enclosed areas designated for specific usages. They’re utilized by lab technicians, electronics manufacturers, biotechnology industries, food manufacturing, and even within the automotive industry. By maintaining a stabilized environment that’s free from excessive contamination, whatever is being manipulated or manufactured is protected from substances that may skew or damage the end result. This helps to reduce wasted time, money, and effort within a variety of industries. 

Simply put, cleanrooms help control and maintain the required environment needed for certain procedures, testing, research, and manufacturing to be carried out efficiently. However, cleanrooms are not protected from contamination. Due to fluctuating personnel, handling equipment, and improper cleaning procedures, cleanrooms can become too decontaminated for use. To ensure that the environment stays in pristine condition, here are some best practices for cleanroom cleaning and sanitization

The Importance of Keeping Correct Frequencies in Cleanrooms

Cleanrooms are considered controlled environments where levels of pollutants, microbes, pathogens, and other particles are at a minimum. The level of contamination is measured in particles per cubic meter and the particle sizes are calculated for analysis. When levels of contamination pass a certain threshold, the cleanroom is considered ineffective and unable to provide a safe environment that’s necessary for whatever task is being carried out. For example, city environments tend to contain up to 35,000,000 particles per cubic meter on average. Many of these particles tend to be 0.5 microns or larger in diameter, making the air unfit for many industry standards. Cleanrooms have a far lower particle per cubic meter and particle size. In fact, to be classified as a cleanroom, the room cannot exceed a maximum of 1,000 particles per cubic meter measuring at 0.1 microns. This creates optimal environments for manufacturing, researching, testing, quality control, and more. However, as with many industries, the frequency varies according to your industry and requirements. Some cleanrooms require frequencies far lower than 1,000 particles per cubic meter. This is why finding a professional company that follows high-quality cleanroom cleaning procedures is essential. 

Different Cleanroom Cleaning Procedures

To make sure that the cleanroom achieves the necessary frequency of sanitization, it’s important to implement the correct procedures. One type of cleaning that’s commonly used is wet cleaning. This is a process of removing different sources of contamination using a specific type of cleaning fluid. Wet cleaning goes beyond simply killing pathogens and particles by removing the elements completely. Your professional cleaning company will utilize cleanroom cleaning supplies based on the surface being targeted and sterilization requirements and properly clean all medical equipment

Cleanroom cleaning can also include dry transfer to remove particles from different surfaces. During this process, it’s fundamental that the cloths used are durable enough to eliminate the transfer of particles, fibers, or other materials. To ensure that your cleanroom is completely disinfected and decontaminated, you need to utilize the right equipment. Through the use of HEPA vacuums, EPA-certified cleaners, and advanced misting systems, Bee Line will ensure that your cleanroom is restored to its required frequency.

Basic Cleanroom Cleaning Tips to Consider

In an effort to hold your cleanroom to the highest standards necessary to conduct your work, it’s important to be proactive about minimizing contamination throughout the workday. This is the best way to stay on top of cleanliness and help reduce large disruptions to your environment. To start, here are some basic cleanroom cleaning tips to enforce. 

1. Be Meticulous

Your employees should be familiar with cleanroom cleaning procedures to take care of any disturbances that occur during working hours. They should also make sure that while working in the cleanroom, they move carefully and meticulously to avoid creating disturbances that could spread contaminants. This includes making sure that all of the proper gowns and protective equipment are worn, carrying out actions with controlled motions, and cleaning any contaminants throughout the day. 

2. Avoid Exposure

One of the best ways to improve the stability of cleanroom environments is to limit the amount of contamination that it’s exposed to from the start. Make sure that every item that enters the cleanroom goes through the proper sterilization methods. This includes personnel, equipment, parts, tools, and anything else that crosses the threshold into the cleanroom.  

3. Change and Clean Filters Often

In conjunction with using the proper cleanroom cleaning services, take the time to ensure that all filters are cleaned and replaced regularly. This helps reduce the occurrence of particle accumulation and the spread of unnecessary contaminants. 

4. Keep Floors Clean

The floor inside a cleanroom is one of the easiest places for contamination to accumulate. To reduce the likelihood of excessive contaminants, have personnel utilize shoe cleaners before entering the room. You should also consider adding sticky floor mats near the entrance that will remove particles before they’re tracked into the cleanroom. 

5. Go Slow

Whenever you need to clean something, always use slow, controlled motions that push particles in the same direction as the airflow of the room. This helps to contain particles and contaminants throughout the workday. You should always clean your space from high to low and finish the process with the floor. Doing so will help you avoid recontamination of already disinfected areas. 

By communicating some of the above cleanroom cleaning tips, you’ll help your staff better understand how to keep their environment safe and reduce the risk of unnecessary contaminants. While choosing the correct type of cleanroom cleaning supplies is important, so is the manner in which they’re used. Go slow and avoid swift, rapid movements to keep particles stable, and try to avoid the number of particles that are brought into a room, to begin with.
