Abstract

In the Secretary of State’s view, requirement B3 is met by achieving all of the following.
a. For defined periods, loadbearing elements of structure withstand the effects of fire without
loss of stability.
b. Compartmentation of buildings by fire resisting construction elements.
c. Automatic fire suppression is provided where it is necessary.
d. Protection of openings in fire-separating elements to maintain continuity of the fire separation.
e. Inhibition of the unseen spread of fire and smoke in cavities, in order to reduce the risk of
structural failure and spread of fire and smoke, where they pose a threat to the safety of people
in and around the building.
The extent to which any of these measures are necessary is dependent on the use of the building
and, in some cases, its size, and on the location of the elements of construction.
