Can the Average Distance to be Covered to the Nearest Exit be Used as a Complementary Safety Parameter in a Building?
In a building environment design, the positioning, size and quantity of emergency exits arc fundamental aspects and have intense relationship with the fire safety of the environments.An aspect that is influenced by these parameters is the average distance to be covered by occupants to the nearest exits during an escape in an emergency situation.In certain specific situations, as some environments crowded with severe accident risks in the event of panic during an evacuation, the average distance could be an important factor.A lower average distance value indicates a probable faster evacuation rate, and can be used as a complementary index of safety of an environment.In this work, using a pathfinder type algorithm to determine the value of the average distances to be covered to the nearest exit during an escape of a circular environment, computational experiments were performed, and the relationship between positioning, quantity and size of exits and the value of the average distances were studied.The main general conclusion is the importance of keeping the exits as far away from each other as possible in a given environment, so that a smaller distance to be covered can be obtained.
