Effect of Safety Factors on Timed Human Egress Simulations

This report covers the effect of safety factors on the time taken for humans to escape a building where fire has initiated. Monte Carlo simulation is used to determine the probability of failure to escape in a given fire scenario. The simulations indicate that the safety factor is very influential...
