Abstract :
Our aim in this project is to determine the
safe egress time in the two occupancies i.e. Business and
Institutional Buildings. Safe evacuation in an occupancy
depends on the several factors such as building design
parameters, human psychological behaviour and fire &
safety facilities installed within a premises. The scope of
this project is limited to Business and Institutional
Buildings where occupant load is low as compared to
Assembly building. Furthermore, the safe egress time is
completely based on two factors i.e. ASET and RSET.
Coming to the term ASET stands for Available Safe
Egress Time. ASET is defined as the time period between
fire initiation and onset of life threatening conditions.
The ASET is determined from the time the effects of fire
reach the defensive limits for the safe evacuation. On the
other hand RSET is Required Safe Egress Time. It refers
to the duration of time required for safe evacuation after
the signalling of the fire. RSET is calculated as the sum
of three separate components the alarm time, evacuation
delay and movement time. ASET depends on a variety of
variables associated with the fire scenario, including the
intensity of the fire and the geometry of the fire
(distribution of fire load), fire protection measures and
building spatial environment. However, in any case
ASET should be reasonably greater than the required
safe evacuation time (RSET) for a successful building
evacuation during fire emergencies.
