Inner rooms
Where the only way out of a room is through
another room (Figure 24), an unnoticed fire in
the outer room could trap people in the inner
room. This means of exit should be avoided
where possible. If, however, this cannot be
achieved then adequate warning of a fire
should be provided by any one of the
following means:
• a vision panel between the two rooms
providing adequate vision to give an
indication of the conditions in the outer
room and the means of escape;
• a large enough gap between the dividing
wall and the ceiling, e.g. 500mm,
so that smoke will be seen;
• an automatic smoke detector in the outer
room that will sound a warning in the
