Which practices help prevent cross-contamination between HD and non-HD areas?

• A. All of the above
• B. Dedicated equipment and storage
• C. Clear workflow separation
• D. Validated cleaning processes between spaces

Answer: (A)

Preventing cross-contamination between areas handling hazardous drugs and non-HD spaces relies on layering controls that address different routes the contamination could take. Dedicated equipment and storage keep HD residues from hitching a ride on shared tools or in general shelves, reducing transfer at the source. Clear workflow separation creates physical and procedural barriers so that materials and staff move through the facility in a way that minimizes contact between HD and non-HD work areas. Validated cleaning processes between spaces ensure there is proven, repeatable removal of any residues, with documented evidence that surfaces meet cleanliness criteria before they are used for non-HD work again. Each control tackles a distinct risk—equipment, movement, and cleanliness—and together they provide a comprehensive defense. That’s why implementing all of these practices is the most effective approach to prevent cross-contamination.
