What term is used for material placed on both sides of a door to remove contaminants from shoes or carts?

• A. Walk-off mats
• B. Abatement
• C. Vector
• D. Short-term care facility

Answer: (A)

Walk-off mats are designed to reduce cross-contamination as people and carts move between different cleanliness zones. Placing them on both sides of a doorway creates a transition area where footwear and equipment are wiped or dragged across a rough, absorbent surface, removing soil, moisture, and some microbes before entering a cleaner space. This mechanical removal lowers the microbial load carried into the next area, which is a simple yet effective part of infection control. Abatement refers to reducing a hazard overall, not a specific doorway feature. A vector is something that carries pathogens, not a material used at doorways. A short-term care facility is a type of healthcare setting, not a mat or device.
