Correct conduct in a cleanroom

The demands are constantly increasing when it comes to how employees should work in cleanrooms. Well-trained employees should be able to follow these regulations blindfolded. Even small behavioural tips can make a lot of difference. We explain what is important to know.   

Why is correct behaviour so crucial?

Your company more than likely pays attention to cleanroom compatible clothing and the proper equipment already. But what about the human factor? Often, it’s the employees themselves that contaminate the cleanroom - without being aware of it. Despite hair coverings, face masks, overalls, and cleanroom shoes, even the smallest particles and microorganisms can still enter the cleanroom. Sources of contamination such as make-up, jewellery, and personal items are often underestimated. More needs to be done to prevent this from happening.

A lot also depends on the working equipment. Standard paper and writing utensils are not the only potential sources of contamination. It's necessary to find equivalent alternatives that are suitable for cleanrooms.

You put on overalls and gloves and then enter – it sounds easy, but it isn't. Everyone needs to be aware of the code of conduct for cleanrooms, and then make sure to follow it to the letter. For example, abrupt and uncontrolled movements whirl up particles that can settle on sensitive products. Take more care with your actions so that you can reduce particle movement.

Tips for working optimally in the cleanroom

No make-up, no jewellery, no smoking – your employees usually know these basic rules. However, experience shows that practice makes perfect. For example, if you know that your wedding ring and ear studs release particles and skin flakes due to friction, it is easier to just forego your jewellery.


Did you know, for example

  • that controlled, slow movements release fewer particles.
  • that it’s important to keep a distance between colleagues
  • that it’s important reduce communication to a minimum.



New habits can easily be trained, you just need the willpower.

We also shed light on details you may not have noticed so we can better demonstrate the importance of proper conduct.
