An Air Filtration Device (AFD) is used to create negative air pressure differentials between which areas?

An Air Filtration Device (AFD) is primarily used to create a negative air pressure differential between a containment area, where hazardous materials or contaminants are present, and unaffected areas of a property. This negative pressure is crucial for preventing the spread of contaminants from the affected area to other parts of the space.

By establishing this pressure differential, the AFD helps to confine particles, airborne pathogens, or volatile organic compounds within the designated containment space, thereby protecting the health of the workers and occupants in the unaffected areas. The function of the AFD is specifically aligned with the goals of the Trauma and Crime Scene Technician (TCST) course, highlighting the importance of safety and containment in dealing with trauma or crime scenes.

The other options discuss different areas but do not address the main purpose of the AFD in relation to contamination control. The primary function of the AFD is not applicable to interactions between restrooms, cleanup sites, storage areas, or offices regarding negative air pressure differentials.
