Contamination control mat acts by attracting particles, dust and contaminating agents down from the soles of shoes or conveyed by the wheels of carts and trucks, holding on its “tacky” surface. The positioning, along the walking direction allowing at least 3 steps for each foot or at least 3 of complete turn of wheels, is crucial for the functionality and efficiency of the mat. A preliminary survey of the internal layout of the flows of goods and workers should be considered carefully in order to optimize and maximize the action of the mat. Water or water and a low detergent or cleaner or sanitizer mix are the means to remove and clean then the mat with a mop or squegee. Simple, practical and efficient.
