ICC Commercial Building Inspector Practice Test

In which situation would the horizontal exit not be the only exit?

1. When there are alternative paths available

2. When a single staircase is present

3. When it serves multiple floors

4. When it is a required exit for egress

The correct answer is: When there are alternative paths available

A horizontal exit is designed to provide a means of egress from one part of a building to another that is at the same or approximately the same level, typically utilized when vertical exits like staircases are not feasible. In situations where there are alternative paths available, the horizontal exit would not be the only exit since occupants would have other means to safely exit the building, whether through additional vertical exits, another horizontal exit, or multiple doorways on the same level. Alternative paths can include doorways leading outside, adjacent areas with exits, or even different sections of a complex designed to facilitate egress. Hence, if occupants have multiple options available that meet egress requirements, the horizontal exit's designation as the only route does not apply. This might be especially relevant in larger buildings where safety systems such as fire exits and multiple escape routes are integrated into the design for enhanced safety.
