What is the maximum vertical spacing allowed for fireblocking?

The maximum vertical spacing allowed for fireblocking is at floor and ceiling levels, which serves as a crucial measure in fire safety within a building. Fireblocking is a method used to prevent the spread of fire and smoke through concealed spaces in a building, and is essential in protecting the integrity of a structure during a fire event.

By limiting the vertical spacing of fireblocking between floors and ceilings, it effectively reduces the potential for fire to travel upward or downward through these concealed spaces. This is particularly important in multi-story buildings where the risk of fire spreading between floors can pose a significant threat to the safety of occupants.

The other options mentioned do not reflect established regulations regarding fireblocking. For instance, while fireblocking is important at roof eaves or around windows and doors, these do not represent the maximum vertical spacing requirement in the same way that spacing at floor and ceiling levels does. Fireblocking requirements are outlined in building codes and are primarily focused on ensuring that vertical spaces that connect different levels, such as those between floors and ceilings, are adequately protected against the movement of fire and smoke.
