What is the maximum allowable spacing between fire blocking in a concealed wall?

The maximum allowable spacing between fire blocking in a concealed wall is defined by building codes to enhance fire safety by preventing the spread of fire through concealed spaces. By limiting the distance between fire blocking to 10 feet, the codes ensure that even if a fire starts in one section of a concealed wall cavity, the fire blocking will inhibit the vertical and horizontal spread of flames and smoke to adjacent areas.

This requirement is designed to compartmentalize the wall cavities and help contain potential fires to localized areas, giving occupants more time to escape and allowing firefighters to control the situation more effectively. The specifics can vary based on local building codes, but 10 feet is a commonly recognized standard that aligns with fire safety principles in construction.
