What Is
Fire Compartmentation?

Fire compartmentation is an important element of ‘passive fire protection’ and is achieved by dividing the premises into ‘fire compartments’ through the use of fire doors, floors and walls of fire-resisting construction, cavity barriers within roof voids and fire stopping to services that penetrate through these dividing elements.

Fire Compartmentation

In certain premises, particularly those where there is a sleeping risk such as Care Homes, Hotels, Apartments etc. the buildings are designed and constructed in such a way as to prevent the spread of fire and smoke from one part of the building to another, this is known as “compartmentation”. This is achieved by constructing fire compartment walls, ceilings and floors in such a way that prevents fire spread.

Where there are door openings within compartmentation walls, they should be provided with appropriate fire doors. Any other penetrations that pass through the compartment walls, ceilings or floors such as pipes, ducts, cables, conduits, joists, purlins and rafters must be fire-stopped to prevent the spread of fire and smoke via these routes.
