Tolerable Fire Risk Criteria for Hospitals

The aim of this study was to establish tolerable fire risk criteria for hospitals. The event tree technique was used to assess the safety level in a model hospital building. Risk profiles were derived and tolerable criteria established by evaluating the risk. The motivation behind this methodology is that buildings designed completely in accordance with today’s regulations must be considered safe by society. A representative hospital geometry was equipped with three different fire safety designs, all complying with performance-based regulations. A standard method for the application of fire safety engineering principles when designing fire protection in buildings is presented. An extensive quantitative risk analysis has been carried out. The probability and consequences of each sub-scenario have been calculated by analysing fire development and the evacuation process
