Health Care Occupancy is defined as an occupancy used for medical or other treatment or care of four or more persons where such occupants are mostly unable to self-preserve due to age or disability, or security measures not under the occupants' control.

• A. An occupancy used for educational purposes.
• B. Health Care Occupancy
• C. Residential Occupancy
• D. Mixed Occupancy

Answer: (B)

The main concept is the specific definition of Health Care Occupancy in NFPA 101. This category covers spaces used for medical treatment or care of four or more people who are largely unable to self-preserve due to age or disability, or when security measures required by licensing or facility policy are not within the occupants’ control. That combination—medical treatment or care plus limited ability to evacuate and/or reliance on staff or controls—defines health care occupancy.

This aligns with facilities like hospitals, nursing homes, clinics, and similar settings where patients or residents need assistance and safety systems are tailored to their needs. The other options describe uses that don’t fit this medical-care-and-evacuation context: educational spaces are for learning, residential spaces are housing, and mixed occupancy refers to combining different use types, none of which match the defining medical-care and vulnerability criteria.
