In facility construction planning, the Infection Control Risk Assessment (ICRA) is used to mitigate sources of microbes through which aspect?

• A. Staffing Schedules
• B. Architectural Design
• C. Equipment Procurement
• D. Cleaning Protocols

Answer: (B)

The main idea is that infection risk during construction is controlled by how the building is designed and how spaces are arranged and protected. The Infection Control Risk Assessment focuses on proactive design decisions that limit how microbes, dust, and contaminants can move through the environment. Architectural design sets up physical barriers, containment zones, and dedicated construction pathways that keep patient care areas isolated from dusty work zones. It also defines ventilation strategies, such as appropriate air changes per hour and pressure relationships (for example, negative pressure in construction areas or isolation-like setups where needed), to prevent contaminated air from spreading. The choice of durable, cleanable materials and sealed building interfaces reduces microbial harborage and simplifies disinfection. Even aspects like separate waste and water systems are planned to minimize biofilm and cross-contamination.

Operational elements like cleaning protocols and staffing schedules remain important for ongoing infection control, but they work within the framework created by design. They cannot substitute for design decisions that physically reduce sources and pathways of microbes in the built environment.
