Question 79

The roof of a building used as a sundeck must have vent stacks terminating at least 5 feet above the deck.

The roof of a building designated as a sundeck requires that all vent stacks terminate at a minimum height of 5 feet above the deck for safety and functionality.

A) all vent stacks terminating through the roof MUST terminate AT LEAST how far above the deck

This option does not provide a specific measurement and is therefore not accurate. While it states a requirement, it lacks the definitive answer regarding the minimum height for vent stacks.

B) 6 inches

Terminating vent stacks at 6 inches above the deck is insufficient for a sundeck. This height does not comply with safety regulations and could lead to issues with ventilation, making it an incorrect choice.

C) 5 feet

This is the correct answer as it specifies the required height for vent stacks on a sundeck. A minimum of 5 feet ensures adequate clearance for ventilation and safety.

D) 7 feet

While terminating vent stacks at 7 feet would provide more clearance, it exceeds the required minimum. This makes it an incorrect choice since the question asks for the minimum height.

E) 10 feet

Like option D, 10 feet is significantly higher than the necessary minimum. Although it provides ample clearance, it is not the required height, rendering it incorrect.

Conclusion

The correct answer is 5 feet, as it meets the necessary safety and functional requirements for vent stacks on a building's sundeck. Other options either do not provide a specific measurement or exceed the minimum height, which is not what the question seeks. Thus, option C is definitively the only correct choice.
