Which NFPA 72 operating mode is defined as an area where someone is at a constantly attended location at one or more locations and is concerned with implementing emergency actions?

• A. Public
• B. Attended
• C. Nominal
• D. Private

Answer: (D)

In NFPA 72, the operating mode describes who is actively involved in responding to alarms and who implements emergency actions. The scenario described—someone being at a constantly attended location at one or more sites and having responsibility for carrying out emergency actions—fits the private mode. This mode is centered on a designated individual or team who is always present at a fixed location and is tasked with taking action during an alarm, such as initiating evacuations, coordinating with responders, or following a preplanned emergency procedure. Public mode would imply occupants in the area respond themselves or that the space is publicly accessible, without a designated responder at a fixed station. Attended mode indicates a person is present, but the description here emphasizes continuous attendance and assigned emergency actions, which is more specific to private mode. Nominal isn’t a mode that describes this kind of proactive, action-oriented staffing. So the private option best matches the described situation.
