When Cleanliness Counts, Count on Us Cleanliness is important for any industry, but for the EMS (Emergency Medical Services) industry, it's essential. At Bio Shield Tech, we help companies protect their employees, patients, and customers from potentially harmful bacteria with a full suite of antimicrobial and personal protection products. Inside an emergency vehicle, hospital, or health care facility, thousands of surfaces can potentially become contaminated by bacteria, mold, and fungi during the course of an ordinary workday. Our revolutionary antimicrobial protected coatings are applied to these surfaces to preserve hygiene and help ensure the longevity of expensive equipment.
