Which of the following is not a primary focus of NFPA 101?

• A. Occupant safety
• B. Means of egress
• C. Fire protection system design specifics like hydrant sizing
• D. Exterior site security

Answer: (D)

NFPA 101 focuses on protecting people inside buildings during emergencies, so its main emphasis is on how occupants stay safe and can evacuate. This includes ensuring safe means of egress—the paths, exits, doors, stairways, and lighting that allow people to leave quickly and safely—and the overall provisions that keep occupants protected as a fire or other hazard develops. It also covers fire protection features—like alarms, detection, and basic system capabilities—that support safe evacuation and response.

Exterior site security, such as perimeter protection or access control around the building, falls outside this life-safety scope. Those concerns are typically addressed by security standards and policies rather than by NFPA 101. Fire protection system design details, including hydrant sizing, are technical design considerations that may be related to life safety but are governed by other standards; NFPA 101 centers on whether the available protection features contribute to occupant safety rather than on in-depth hydraulic calculations.
