Fire compartmentation is a fundamental concept in fire safety and building design. It involves dividing a building into separate compartments or areas to limit the spread of fire, smoke, and heat from one area to another. The purpose of fire compartmentation is to contain a fire within a defined space, allowing occupants to evacuate safely and providing time for firefighting operations.

  • Compartments: A compartment is a designated area within a building that has fire-resistance-rated walls, floors, and ceilings, which are intended to prevent or delay the spread of fire. Compartments can be individual rooms, floors, or sections of a building.

  • Fire Resistance: Fire-resistance-rated construction materials, such as fire-rated walls, floors, and doors, are used to create the boundaries of compartments. These materials are designed to withstand fire for a specific period, known as the fire-resistance rating. The rating depends on factors such as the type of building, occupancy, and local fire safety regulations.

  • Fire Barriers: Fire barriers are construction elements that separate compartments or divide large compartments into smaller ones. They are typically fire-rated walls or floors that extend from one side of the building to the other, creating a continuous barrier against the spread of fire.

  • Fire Doors: Fire doors are specially designed doors that have fire-resistance ratings. They are installed within fire barriers and compartment boundaries to allow access between compartments while maintaining their fire integrity. Fire doors should remain closed and self-close in the event of a fire to prevent fire and smoke from spreading.

  • Penetrations and Openings: Openings and penetrations in fire-rated walls, floors, and ceilings, such as doors, windows, ducts, and pipes, should be properly fire-stopped or protected to maintain the integrity of the fire compartment. Fire-resistant materials, such as fire-resistant seals or intumescent products, are used to seal these penetrations and prevent the passage of fire and smoke.

  • Compartmentation Strategy: The design and implementation of fire compartmentation depend on various factors, including the building's use, occupancy, size, and local fire safety regulations. A comprehensive fire safety strategy considers factors such as exit routes, emergency evacuation plans, fire detection and suppression systems, and the placement of fire-rated compartments to maximise safety.

Fire compartmentation plays a crucial role in preventing the rapid spread of fire, protecting lives, and reducing property damage. It forms a fundamental part of building codes and regulations to ensure adequate fire safety measures are in place.
