ICC Commercial Building Inspector Practice Test

What is the maximum exit access travel distance for a walkway with 50% opening and an automatic sprinkler system?

1. 200 feet

2. 300 feet

3. 400 feet

4. 500 feet

The correct answer is: 400 feet

The correct answer is based on the provisions found in the International Building Code (IBC) regarding exit access travel distances in different occupancy types and conditions. For a walkway that has at least a 50% opening and is equipped with an automatic sprinkler system, the maximum exit access travel distance can significantly increase due to the provided safety measures. When a space has a specific level of opening and is protected by an automatic fire suppression system, the intent is to provide an enhanced safety environment, which allows for longer travel distances to exits. In many cases, the distance can extend up to 400 feet, accommodating the design's safety features more effectively. This length is intended to ensure that, even in larger or more complex building designs, occupants have reasonable access to exits when sprinklers are in place to mitigate fire hazards. Other distances specified for various situations, such as without sprinklers or with limited openings, are generally shorter to reflect the increased risk associated with those configurations. Therefore, given the conditions of a 50% opening and an automatic sprinkler system, a maximum exit access travel distance of 400 feet is the appropriate standard to follow.
