Compartmentation is one of the most important aspects of the fire
safety design of the building. For example, in high rise residential
buildings, each flat unit is designed in such a way that it is separated
from the other flat so that the fire spread from one flat another can be
avoided. And if the flat is large in area, then it gets compartmented
further internally to provide the occupants means of escape.
