Human behavior in critical situations is at the core of all concerns about the fire safety of buildings, regardless of their destination.
The way in which the human caught in the fire reacts to the risk factor to which he is exposed, his behavioral response to the direct
action of the fire, or his psychological response to the effect of the fire (temperature, smoke opacity, reduced visibility, exposure to
toxic combustion gases), are all factors that can drastically influence the required safe escape time. All these considerations underlie
the modern evacuation models used both in the design phase of fire-safe buildings and during the post-event investigation of these
undesirable situations. This paper analyzes the possibilities of using the computerized evacuation models and highlights the
advantages of using the engineering approach in the field of fire safety.
A study was conducted using Pyrosim specialized software and one of the most popular evacuation model, namely FDS+Evac, in
order to evaluate the numerical model’s capability to predict the occupant evacuation in the case of a presumptive building fire
scenario.
