What is the maximum horizontal spacing for fireblocking within concealed spaces of wood-framed stud walls?

1. 5 feet

2. 8 feet

3. 10 feet

4. 12 feet

The correct answer is: 10 feet

The maximum horizontal spacing for fireblocking within concealed spaces of wood-framed stud walls is established at 10 feet. This requirement is based on fire safety standards that aim to prevent the spread of fire within walls and other concealed areas of a building. Fireblocking is critical because it helps to compartmentalize fires, slowing their spread and providing additional time for occupants to escape and for firefighters to respond. In wood-framed construction, concealed spaces can allow fire to travel quickly. By limiting the spacing between fireblocking to 10 feet, it ensures that any potential ignition source is contained more effectively, reducing the risk of a fire spreading across larger undivided areas. Proper installation of fireblocking using materials appropriate for the application also plays a role in overall structural integrity and safety. Understanding this requirement is crucial for residential inspectors as they evaluate compliance with fire safety codes during inspections. Familiarity with the latest building codes ensures that inspectors are up-to-date on best practices for fire safety in residential construction.
