Penetration of fire walls must comply with which section of the NCBC?

• A. Section 714
• B. Section 715
• C. Section 716
• D. Section 717

Answer: (A)

The penetration of fire walls is specifically addressed in Section 714 of the North Carolina Building Code (NCBC). This section outlines the requirements and standards for any openings or penetrations in fire walls to maintain the fire-resistance rating of the assembly. These standards are crucial because they ensure that fire walls continue to perform their function of restricting the spread of fire and smoke, which is vital for the safety of the building's occupants and to protect property.

Section 714 stipulates the materials and methods that can be used for sealing or protecting these penetrations, ensuring that even when services like pipes, ducts, or electrical conduits pass through the fire wall, the integrity of the fire separation is maintained. This is essential for compliance with fire safety regulations, and adherence to these standards is often monitored during inspections.

In contrast, other sections like 715, 716, and 717 cover different aspects of fire protection systems, types of fire-resistant materials, and construction requirements but do not specifically address the penetration requirements for fire walls, which is why Section 714 is the correct reference for this matter.
