Use as disinfecting foot baths at fish hatcheries and farms. When used with the disinfecting solution, the mats will disinfect a person's footwear before entering a controlled area. The unique design reduces evaporation of the solution and it also helps to reduce contamination of the disinfectant. These mats feature a permeable upper fabric, which enables disinfection of shoes, and boots. The bottom and sides are made of non-permeable material to prevent leakage or leaching of the disinfection solution. Simply pour disinfecting solution onto the top to fill.
