Performance-based fire safety engineering (FSE) is an important tool for constructing fire safe environments. The efficiency of such a tool is dependent on several areas of knowledge, such as the behaviour of humans in relation to fires and of course the nature of the fire itself. However, much of the necessary information for using the FSE tool efficiently is today either lacking or poorly understood. A fire hazard analysis is of course relying on the assumptions of fire growth that is done by the engineer. The time scale for the fire is depending on the selection of the design fire and this time scale will in most cases determine the time for further fire spread, the probabilities for casualties, the time available for escape and so on. Therefore, the method to arrive at a plausible design fire has been the objective for much research work over the years. However, methods that are envisaged internationally are still simple and rather crude and needs to be further improved to be more versatile.
