Since then National Fire Safety Code have been significantly strengthened.

In November 2010, a fire occurred at an elderly care center in Pohang city, and There were 17 deaths and 10 injured. As the number of elderly people increases, the number of elderly welfare facilities such as nursing homes is also increasing, and the number of elderly welfare facilities has increased to 75,708 in 2016 from 50,517 in 2003. In other words, comparisons of the simulation results give reason to conclude that in the building in question, users can safely evacuate outside the building before the critical fire parameters are exceeded.Currently, the number of elderly people aged 65 or older in Korea is increasing steadily, reaching 14.3%. Simulations with PyroSim proved that in the adopted calculation scenarios (variants), the value of temperature and the degree of smoke will not reach a level threatening the safe and effective evacuation. From the point of view of safety of the terminal under analysis, especially safe evacuation under fire threat conditions, the critical parameters that were mainly focused on were the temperature distribution (in quantitative terms) in the immediate vicinity of the fire source and the maximum smoke level (in qualitative terms). Obtained results from computer simulations using Pathfinder indicate that the determined evacuation time for the assumed assumptions and fire scenarios was 46 s for an evacuation of 50 people and 82 s for an evacuation of 600 people. The essence of the studies was to determine the time of effective and safe evacuation at two variants of the ignition source and differentiated configuration of the computational mesh and dimensions of elements (a total of four calculation scenarios). To achieve this goal, the PyroSim and Pathfinder software was used. The aim of this study was to determine the rate of formation of selected fire threats in the terminal of a local passenger airport and to estimate the time for safe and effective evacuation of occupants of the terminal covered by fire.
