What is the minimum number of exits required for a story or portion thereof with an occupant load of 500 or less?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

Two means of egress are required for a story or portion with an occupant load up to 500. This ensures there are at least two independent paths to exit, providing an alternate route if one path is blocked by fire or smoke and helping to prevent overcrowding on a single exit. It also helps keep travel distances and exit capacities within safe limits so all occupants can evacuate in a timely manner. A single exit would create a bottleneck and reduce safety, which is why two exits are specified for this occupant load.
