As quality regulations within industrial production cycles became more and more stringent, action had to be taken to control contamination between different production departments. One of the ever-present issues is that of dirt carried by the wheels of the trolleys and pallet trucks that circulate, but also by the soles of the shoes of the operators themselves. The WZ washable decontamination mats were therefore installed in some strategic steps of the production cycle. In a couple of areas, action was also taken with absorbent an anti-slip mats, DRY RL MAT, because of wet and damp residues remaining on the floor.
