SAFE EGRESS TIME-ASET/RSET


Simulation


ASET/RSET

ASET (Available Safe Egress Time)
It is the amount of time available for safe evacuation of occupants from an occupied enclosure in case of a fire. It is calculated by simulating a fire scenario (fire & smoke simulation) and evaluating the time available to the occupants for safely evacuating the fire affected premises before the conditions become untenable in terms of temperature, visibility and carbon monoxide.

RSET (Required Safe Egress Time)
It is the actual amount of time required for safe evacuation of occupants from an occupied enclosure in case of a fire. In simple words, the ASET should be greater than or equal to 1.5 times the RSET.
