Humans are the main source of contamination in cleanrooms<\/a>, accounting for up to 40% of all contamination in cleanrooms. This is true for both particulate contamination and microbiological contamination. Cleanroom clothing acts as an excellent protective barrier, creating a barrier between the individual, the cleanroom, and the product. Therefore, cleanroom personnel must wear special clothing in addition to following hygienic principles. In this article, we will discuss cleanroom clothing.<\/p>

Employees are often the largest and most important source of contamination when processing products and materials that require a higher level of cleanliness and hygiene. Other sources of contamination can also impact cleanliness levels, but people are the most important source. Four independent sources of contamination can be identified at the product processing site:<\/p>

Humans (employees) Ambient air Ambient surfaces Product and or process (the main work that employees do)<\/p>

The four sources of contamination, namely employees, air, surfaces, and product; are all interconnected, as shown by the two-way arrows. In general, all four are equally important, but in practice, it is necessary to see which ones are of the highest importance in relation to the work being done.<\/p>

Employees can contaminate a product or production process through the surrounding air, direct and indirect contact with various surfaces, and also through direct or indirect contact with the product or process equipment. The most important source of human-origin contamination is the natural process of continuous shedding of epidermal cells.<\/p>

Cleanrooms and other controlled environments are designed to protect the product, process, or employees from various contaminants and are of great importance. Proper design and construction of a cleanroom is not enough for protection,<\/p>

\"Cleanroom<\/p>

When people enter a cleanroom, the cleanliness of the room changes significantly, as humans produce a significant amount of particles (including non-viable particles and microorganisms), which is largely due to the replacement of the outer layer of skin. The process of replacing the outer layer of skin is continuous and ongoing twenty-four hours a day. It usually takes about four days to replace the entire surface of the skin, which shows that the rate of exchange of this process is very fast. Old skin turns into dried-up skin flakes and, after loosening, separates from the body.<\/p>

Cleanroom clothes prevent many of these detached flakes from being released and hold them in place. However, some of these particles enter the air of the room around us. During this process, the human body releases between 6 and 13 grams of skin per day. In this way, about 3.5 kilograms of skin is separated from the body annually. The number of particles produced by men is higher than that of women, which is mainly due to hormonal reasons. Also, the amount of skin particles produced by younger people is more than that of older people.<\/p>

Despite the fact that these flakes are made of dead materials, they are considered to be important contaminants for biosensitive activities (i.e., work with materials and production processes that may be contaminated by microorganisms). This is because the surface of our skin is more or less covered with microorganisms that are part of our natural flora. In practice, this means that even if the released flakes are “dead,” they should also be considered as “viable particles” because they are likely to contain live microorganisms.<\/p>

Why is it important to wear cleanroom clothing?<\/h2>

Cleanroom clothing is clothing worn by personnel working in a cleanroom or controlled environment and is considered one of the personal protective equipment. Cleanroom clothing is designed to prevent the release of particle contamination from human body into the cleanroom.<\/p>

The use of such clothing is essential to protect personnel, especially when they are handling chemical hazards. Cleanroom clothing is typically non-shedding, meaning that it leaves nothing behind. Additionally, these garments are not woven and are completely safe to wear in a controlled environment.<\/p>

Cleanroom Clothing Requirements<\/h2>

Different types of cleanrooms require different cleanroom clothing. The cleanroom gown protocol is designed to ensure contamination control and compliance with standards such as ISO, EU-GMP. According to the ISO classification, the use of cleanroom gowns is only permitted in ISO Class 7 and ISO Class 8 cleanrooms. Additionally, personnel entering ISO Class 5 and Class 6 cleanrooms must wear cleanroom gowns with a cap, gloves, and boots.<\/p>

The material of cleanroom clothes<\/strong><\/p>

The purpose of wearing cleanroom clothes is to prevent the spread of human contamination into the cleanroom. The choice of cleanroom clothing material is of utmost importance. For example, natural materials such as cotton are not suitable for use in cleanrooms as they release dust and particles. Instead, synthetic materials are preferred for cleanroom clothing. Three types of synthetic materials are used, depending on the application:<\/p>
