1.5.4 Travel Distances

Shop and Commercial use:

Maximum travel distance where escape is possible in:
One direction only (m) More than one direction (m)
Shop and Commercial
18m 45m
The graphic below shows a review of travel distance provision in the model store.

Figure 2-2 Travel Distance Assessment

In this instance, the travel distance limitations for escape in two directions are satisfied. It is
noted that a designated fire escape route should be kept clear (both Front-of-House and

Back-of-House) and consideration should be given to the onward external escape path from
the rear final exit. In instances where the single direction of travel cannot be met from all

areas of the store, it may be appropriate to designate a secondary means of escape to allow
for the assessment to take account of the provision of escape in more than one direction.

1.5.5 Exit Signage

All escape routes should be distinctively and conspicuously marked by an exit sign in

accordance with BS ISO 3864-1 and BS5499-4.
