This is a case where customer was searching for more shoe cleanliness when acceding to an E.P.A. zone through on a test control of ESD individual protections. WZ mat was placed before the dual-foot metal plate ESD tester, so clean soles offer a more efficient test and true values. Stepping forward, another WZ mat mas placed before acceding to a cleaner zone (not literally a cleanroom) in front of changing room’s door right before moving into the critical area where more delicate operations will then take place. Again, shoe’s soles come cleaner with easy pass on. Same floor protection took place in from of the warehoues’s big door, where goods are coming in. To protect operators (small door) access from outdoor, it’s used a different kind of anti-slip, absorbent self-adhesive mat (DRY ROLL MAT – easy to install), where wet and gross residues is easily retained. Useless to say that this kind of mat is not offering same features as WZ mat does, but this is what customer needs for operators and drivers walking into.
