In such cases, the walls and floors are referred to as compartment walls and compartment floors.

Introduction

Fire separation is the art of protecting buildings, areas within buildings or dwellings by walls and floors that have been constructed to resist the spread of fire into adjoining areas for designated time periods. These time periods will be stipulated in accordance with the Building Regulations and local authority dictates. Thus, the walls and floors become fire separating elements and taken together will divide the building into distinct fire zones called ‘fire compartments’. In such cases, the walls and floors are referred to as compartment walls and compartment floors.

In general, when any of those elements is prefixed by the word compartment, it designates that it has been designed and constructed to have a specific period of fire resistance, typically for 30, 60, 90 or 120 minutes. The level of performance will depend on the type of building in question and the requirements of Approved Document B of the Building regulations (England and Wales) or Part E (Scotland and Northern Ireland).

A compartment wall or floor will resist the passage of fire into adjoining compartments or accommodation for the specified time period before it becomes structurally compromised. The period of time during which the element acts as a barrier to the spread of fire is designed to contain the fire; prevent it from developing into a much larger fire, gives people in adjoining accommodation sufficient time to escape the building, and limits the damage caused.

In cases where the fire separating element includes an opening, such as a door, internal window, penetrating duct or access panel, it too must have the same fire rating as the element in question in order to maintain the fire separation qualities of the construction. If this were not the case, the fire separating qualities of the element would be compromised. When a duct penetrates a compartment wall or floor, it must be ‘fire stopped’ (ie material is packed around the duct to create a seal and so achieve the same fire resistance as the wall or floor and ensure the opening does not form a route for fire spread).

In a simple four-storey office building, with each floor comprising two escape stairs and an open plan office area with no internal partitions, the escape stairs will be enclosed by fire walls and fire doors. This makes each staircase a multi-storey fire compartment which will be designed to ensure that any outbreak of fire in the office areas cannot penetrate into the protected stair for the designated fire period.

Other considerations that will affect the degree of sub-division are the height of the building, its fire load and the availability of a sprinkler system.
