In all of these examples the following basic
principles apply:
• The farthest point on any floor to the final
exit or storey exit to a protected stairway is
within the overall suggested travel distance
(see Table 2).
• The route to and the area near the exit is
kept clear of combustibles and obstructions.
• The fire-resisting stairway is kept clear
of combustibles and obstructions.
• The escape route leads to a final exit.
• Where the stairway is not a protected
stairway, the final exit is visible and
accessible from the discharge point of the
stairway at ground floor level.
• High-risk rooms do not generally open
directly into a protected stairway.
• If your fire risk assessment shows that
people using any floor would be unaware
of a fire you may require additional fireprotection
measures, e.g. an automatic
fire-detection and warning system.
• There should be more than one escape
route from all parts of the premises (rooms
or storeys) except for areas or storeys with
an occupancy of less than 60. The figure of
60 can be varied in proportion to the risk,
for a lower risk there can be a slight
increase, for a higher risk, lower numbers
of persons should be allowed.
