When we walk, every step releases around 215,000 particles—bacteria, dust and other contaminants—into our surroundings. Before they enter the anteroom, staff members remove their shoe coverings using a hands-free, externally vented, pneumatic shoe cover remover. Then, upon entry into our anteroom, everyone immediately steps onto a Dycem® contamination control mat. This electrostatically charged, antimicrobial floor covering retains up to 99.9% of foot and wheelborne particles, helping to remove any outside contaminants potentially on staff facility shoes. Another shoe covering is then applied. Only then are staff members ready to cross the line of demarcation—embedded in the floor, not taped, to avoid any contaminants in the adhesives.
