What is the minimum fire resistance period for a brick wall?

The minimum fire resistance period for a brick wall is typically marked at one hour. This duration reflects the ability of a wall constructed from brick to withstand exposed fire conditions without losing its load-bearing capacity or integrity.

Brick, due to its material properties, can effectively resist the passage of fire and limit its spread between compartments within a building for this established period. Regulations and building codes set these fire resistance ratings to ensure that walls contribute to the overall safety of a structure during a fire incident, allowing sufficient time for occupants to evacuate and for emergency services to respond.

The other options present lesser fire resistance periods, which do not align with standard building codes and best practices for fire safety concerning brick walls. Fire-resistance ratings lower than one hour would typically apply to other materials or less critical structural elements, but for brick, the one-hour rating is the generally accepted minimum to ensure adequate safety measures in building design.
