The customer wanted to contain cross-contamination in both directions, from production to offices and vice versa, due to the production of cosmetic bases and therefore limit the color of the floor itself. It was agreed to protect 3 different intermediate passage areas with the CZ washable decontaminant mat (https://www.acsupply.it/en/products/cleanroom/item-483) and to provide instead a rest and coffee break area with a non-slip and absorbent mat DRY ROLL MAT (https://www.acsupply.it/it/products/cleaning/item-1525). Already in the first two meters the traces left by the operator’s shoes are clearly visible.
