Customer had a corridor access to a critical area both outdoor and internally from the offices and from the changing room and toilets. Previously a fixed sit over bench was also installed where workers wore shoecover and coats with a significant increase in time and cost. Now, providing the entire area of a washable fixed contamination control mat for about 1.2×8.0meters, the whole corridor can be run in any way without special obligations or sit-over bench. In the photo you see how contamination is already stopped within the first two meters, where you can access the changing room on the right. Also, keep in mind that in this way even the escape route, if necessary, without the fixed sit over bench, is safer and easier.
