Customer wants to control direct production and warehouse access to offices and laboratories so as to limit contamination and general dirt while having little space available. In the case of raised floors, we opted for 60×60cm pre-adhesiviized panels (http://www.acsupply.it/en/products/cleanroom/item-997), having first laid the bottom of each tile with a thorough cleaning. High visibility perimeter edging has also been inserted to give greater emphasis to the area where operators have to pass, as well as protection for any rolling carts that have to pass. Where instead the bottom was made of smooth and compact resin, we used an ultra-thin and pre-adhesive antibacterial decontaminant mat (http://www.acsupply.it/en/products/cleanroom/item-1267) and completed on request with the high visibility edging for the above reasons. The result is all evidence and impact for operators entering critical areas Ordinary maintenance remains easy and fast, even with the small dimensions of the three carpets (120×120cm). When mats are worn then just remove them and replace them with new mats always inside the high visibility frame.
