Fire compartmentation is a crucial strategy utilised to prevent the spread of fire and smoke within a building. This is achieved by dividing the structure into smaller compartments that feature fire-resistant walls, floors, and doors, which are built to contain the fire and decrease its progression.

Fire compartmentation is a requirement in buildings where fire risks are high, such as hospitals, schools, and residential care homes. It is also commonly used in commercial and industrial buildings where the presence of flammable materials and equipment increases the risk of fire.

Apart from preventing the spread of fire and smoke, fire compartmentation can also safeguard the structural integrity of the building, giving occupants more time to evacuate and reducing the risk of injury or loss of life. Moreover, regular inspections and maintenance of fire-resistant barriers are vital to guarantee their effectiveness in the event of a fire.
