What is the minimum height required for a vent extension on a roof used for assembly purposes, such as a promenade?

• A. 5 feet
• B. 6 feet
• C. 7 feet
• D. 8 feet

Answer: (C)

The minimum height required for a vent extension on a roof used for assembly purposes, such as a promenade, is 7 feet. This height is established to ensure safety and functionality in areas that are accessed by people. A vent that is properly elevated reduces the risk of obstruction or interference by individuals engaging in activities on the roof. By maintaining this height, the vent extension is less likely to become a tripping hazard or be accidentally bumped into, which is particularly important in spaces where people congregate or move about. Moreover, an elevation of 7 feet helps ensure that any odors or exhaust emissions vented from plumbing systems are adequately dispersed and do not negatively affect the comfort of individuals in the vicinity. This requirement emphasizes the need for consideration of human activity and safety when designing plumbing systems, especially in areas intended for public assembly.
