Which factors determine the maximum travel distance to a means of egress in NFPA 101?

• A. Occupancy type, whether the building has automatic sprinklers, and whether the area is fully protected by fire protection features.
• B. Building age, exterior color, and window size.
• C. Number of stairs, elevator count, and ceiling height.
• D. HVAC system type, energy code version, and door material.

Answer: (A)

The key idea is that how far people may have to travel to reach an exit is tied to how hazardous the space is and how well it’s protected from fire. NFPA 101 uses occupancy type to classify the level of risk and then adjusts the maximum travel distance based on whether the area is fully protected by fire protection features, like automatic sprinklers and other controls. When the space is fully protected, the risk of a fire blocking the path is reduced, so a longer travel distance can be allowed. If protections are lacking, the distance must be shorter to reduce exposure.

Factors like building age, exterior color, window size, number of stairs, elevator count, ceiling height, HVAC, or door material do not determine the maximum travel distance in NFPA 101.
