In order to avoid the uncontrolled entry of particles, clean rooms are in contact with the outside world only to the absolutely necessary extent. Since humans cause over a third of the contamination occurring in clean rooms, clean rooms may only be entered in special clothing that primarily serves as a filter between the surface of the human body and the clean room environment. Special working materials must be used in clean rooms. Not only the clothing, but also the working materials used in clean rooms must meet special requirements. Clean room paper therefore has a special low-particle surface, and clean room pens are manufactured with particularly tightly sealed sleeves and smear-free ink to keep contamination from these utensils as low as possible. Furniture used in clean rooms must have abrasion-resistant surfaces and a design that prevents particle deposits. Clean rooms at OHB. OHB operates class ISO 8 and ISO 5 clean rooms.
