The maximum occupant load when the exit serves more than one floor is an important element in determining the ________.

• A. Exit capacity
• B. Fire resistance rating
• C. Vertical travel distance
• D. Sound level

Answer: (A)

The main idea is how many people may need to pass through an exit and how that drives the exit’s capacity. When an exit serves more than one floor, you must look at the total number of occupants on all floors that could use that exit. That peak occupant load becomes the demand on the exit, so the exit capacity (how many people can move through the exit safely in a given time) must be enough to handle that load. If the combined occupant load exceeds what the exit can support, you’d need additional exits or wider egress paths to meet the requirement. The other factors don’t determine exit capacity. Fire resistance rating concerns how long a barrier lasts under fire conditions, not how many people can pass through an exit. Vertical travel distance affects how far people must go to reach an exit, which influences egress time but not the capacity of the exit itself. Sound level relates to acoustics and has no bearing on how many people can evacuate through an exit.
