The Large Entrance Disinfection Mat is designed to be placed at the entrance or exit of dairy barns, hog enclosures, poultry houses and fruit, vegetable or grain storage facilities of all types to disinfect the boots and shoes of workers. Disinfection Mat is made with tough poly mesh over a foam core with non-permeable bottom and sides to contain the disinfection solution. When filled, the Entrance Disinfection Mat repels dirt and stays effective for approximately one week before it should be lifted, rinsed, hung overnight to drain and refilled the next day. The mat is designed to be deep enough to disinfect yet shallow enough not to soak the feet. Used on a smooth, level surface, 34″ x 24″ by 1″ deep Large Disinfection Mat holds 2 gallons of solution.
