What is a containment zone, and how is it used during construction near patient care areas?

• A. A containment zone is a physically separated work area with barriers and controlled access designed to prevent migration of dust and contaminants into clinical spaces; it uses barriers, ventilation controls, and access restrictions.
• B. A containment zone is a storage area for personal protective equipment.
• C. A containment zone is a secure area for psychosocial interviews.
• D. A containment zone is a space designated for lunch breaks.

Answer: (A)

A containment zone is a physically separated work area created around construction activities near patient care spaces to keep dust, debris, and contaminants from spreading into clinical zones. It works by surrounding the work area with barriers and controlled access, and by managing airflow so that air moves from clinical spaces into the construction zone or through filtration rather than the other way around. Typical features include sturdy barriers or plastic sheeting that fully enclose the work area, sealed penetrations, dedicated entry and exit points, and ventilation controls that may create negative pressure relative to surrounding spaces. Entry is limited to trained personnel, with proper PPE and decontamination procedures to prevent cross-contamination, and housekeeping is heightened to keep dust contained and waste properly disposed of. This setup protects patients, staff, and visitors from construction-related exposures. The other uses listed—storing PPE, conducting interviews, or providing break areas—do not address containment of dust and contaminants and are not how a containment zone is used.
