In future, male employees in our company will have to wear a beard protector (cleanroom class 8). Is there a statement on how many mm or more this must be worn?
Hair is one of the biggest risks in the cleanroom. Beard protection therefore really makes sense. The longer the hair, the more hair pieces fall off and dirt particles can stick to them. There is no precise statement as to how many mm or more a beard protector must be worn, as this really depends on the risk of contamination. A usual average value is from 2 mm.
