Is self-latching hardware required at doors within openings that are part of the smoke barrier?

1. Yes, it is mandatory

2. No, it is not required

3. Only if specified in the local code

4. Yes, but only during construction

The correct answer is: No, it is not required

Self-latching hardware is not mandated for doors within openings that are part of the smoke barrier according to existing codes and standards. The primary purpose of a smoke barrier is to restrict the movement of smoke and fire, ensuring protective measures are in place to enhance safety during a fire event. While self-closing doors are typically preferred to maintain the integrity of a smoke barrier, the requirement for self-latching hardware can vary based on specific code interpretations and local regulations. In many instances, smoke barriers are designed to function effectively with other forms of door hardware. This means that while self-latching hardware may be beneficial in certain scenarios to ensure that the door remains closed, it is not a strict requirement universally. Building codes might allow for alternative strategies to meet smoke barrier performance criteria, and that’s why simply adhering to self-latching hardware is not a necessity. In conclusion, since there is flexibility regarding the type of door hardware used on smoke barriers, it is accurate to state that self-latching hardware is not a required element for doors within smoke barrier openings.
