How many means of egress are typically required for most occupancies, and what factor influences this requirement?

• A. At least two means of egress; the required number can depend on occupant load, travel distance, and building type.
• B. Three means of egress; influenced by weather conditions.
• C. One mean of egress; determined by building height only.
• D. Four means of egress; independent of occupancy.

Answer: (A)

Two means of egress are typically required to ensure there is an alternate, unobstructed path to safety if one route is blocked by fire, smoke, or congestion. The exact number isn’t fixed for every building; it varies based on how many people might be inside (occupant load), how far people would have to travel to reach an exit (travel distance), and the type or use of the building (building type). In larger spaces, with higher occupant loads or longer travel distances, more exits or wider egress paths are required to keep the journey to safety within code limits.
