Fire And Life Safety


Simulation


Fire & Life Safety
Fire safety is achieved by applying calculations, science, and engineering to determine how a building would respond to fire, rather than by showing that it meets a checklist of prescriptive building and fire codes that may not be appropriate due to a building's unique characteristics or may unnecessarily increase the cost of equipment, installation, maintenance and repair.
The performance criteria are usually related to ensuring that the space remains tenable so that its occupants are not exposed to untenable amounts of smoke or heat, and ensuring that structural collapse does not occur.

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.

Fire Smoke Simulation
A fire breakout in an occupied enclosure such as a mall,airport etc generates a large amount of heat and smoke which prove fatal for any human presence.
Simulation is an excellent tool for simulating a Fire Scenario in an occupied enclosure and visualizing the crucial parameters and conditions for human presence in case of fire.

Evacution Simulation 
The most important objective of a fire and life safety design is to ensure that people can safely escape from a building in an emergency fire scenario.
Evacuation simulation is the prediction of time required for all occupants to escape from the fire zone.
