Uncertainty and Risk Analysis in Fire Safety Engineering
… to perform and has been used extensively in many engineering fields. Both QRA methods have been applied to an example, structured with the event tree technique, to determine the risk to patients on a hospital ward. In addition to the two risk analysis methods, separate uncertainty analysis methods …

Driving safety and safety engineering: exploring risk compensation
… in driving can occur due to the use of safety belts. Risk compensation theories hypothesize that if individuals wear safety belts, they will . drive in a more risky manner than if they do not wear safety belts due to the increased perception of safety they provide. Although much of the …

Decision Analysis in Fire Safety Engineering - Analysing Investments in Fire Safety
… methods to the evaluation of investments in fire safety was investigated, particularly with the aim of being able to suggest a method for analysing a specific investment in fire safety for a specific factory. Attention was directed above all at the handling of cases of large epistemic uncertainty …

Development of pyrolysis models of composite materials for fire safety engineering
The one-dimensional pyrolysis computational tool ThermaKin was used to predict the thermal decomposition behaviour of widely used synthetic polymers (polypropylene (PP) and polyethylene (PE)) with and without additives, in order to investigate the suitability of ThermaKin for novel fire retarded …

A systems-theoretic security model for large scale, complex systems applied to the US air transportation system
… Recent work by Leveson in the area of system safety engineering has led to the development of a new accident model for system safety that acknowledges the dynamic complexity of accidents. Systems-Theoretic Accident Models and Processes (STAMP) applies principles from control theory to enforce …

Flamelet modelling of soot formation in diffusion flames
In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar …

Demand for Extinguishing Media in Manual Fire Fighting
… study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media. Data from the London Fire Brigade (UK) were used to investigate a possible correlation between the area …

The effect of physical properties on flame spread behavior for various paper/bagasse composition
Fire Safety Engineering is an application of science to improve the safety from the destructive effect of the fire. Paper is well known as a material that can easily catch fire. Nowadays, many researchers have been interested to produce paper by using other natural fiber to reduce the usage of wood …

Failure logic modelling: a pragmatic approach
The research discipline of model-based system safety assessment, which has emerged in the last two decades, has attracted a significant amount of interest from academia, industry and government agencies. However, the discipline remains largely unorganised with various individual, often conceptually …

Rail Tunnel Evacuation
In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. More specifically, a theoretical framework that can aid the understanding of human behavior is …

Safety-driven system engineering process
… pace. The creators of the traditional system engineering processes did not anticipate modern complex systems, and the application of traditional processes to complex systems such as spacecraft has repeatedly led to disastrous results. Too often, system safety is considered late in the design …
