Which factor is not used to determine the required number of exits?

• A. Color of interior finishes
• B. Travel distance
• C. Occupant load
• D. Egress width

Answer: (A)

The factor being tested is what drives how many exits a building must have to safely evacuate occupants. The required number of exits depends on how many people might need to exit (occupant load), how far they may have to travel to reach an exit (travel distance), and how much people can flow through each exit (egress width). A higher occupant load requires enough exits to handle the crowd. If travel distance is too long, additional exits or closer ones are needed to keep evacuation times acceptable. The width of the egress paths determines the flow rate; wider exits can support more people and may reduce the need for additional exits. Color of interior finishes is cosmetic and does not influence egress calculations, so it does not affect the required number of exits.
