It simulates the logical and stochastic interdependences of the various events involved with the fall of an object or crane and its consequences. This logical model consists of two main parts (a) the part incorporating the events preceding the falling object/crane on a person consisting mainly of preventing measures; and (b) the part incorporating events following the fall of the object/crane on a person and consisting mainly of measures mitigating the effects of the accidents. Safety measures engineered or procedural aimed at preventing the fall of an object on a person, mitigating the impact of this event on a person and influencing the consequences of a given impact are presented along with the required data for quantification of the logical model. Three levels of consequence severity are considered; lethal injuries; non-lethal permanent injuries; and recoverable injuries. Quantification results are presented for the risk of contact with collapsing, overturning cranes and falling loads from cranes.

Sixty four logical models quantifying corresponding occupational risks are developed under the WORM project. The overall objective of quantifying occupational risk through detailed logic models in WORM is twofold: First from a qualitative point of view the model

From the NH3-t.p.d. experiments it could be concluded that two types of acid sites are present in H-ZSM-5: Weak acid sites corresponding with desorption at low temperature and small &/-/des, and strong acid sites corresponding with desorption at high temperature and large &Hdes. Especially the desorption at high temperature could be explained satisfactorily by theoretical models as presented in literature. From the n-hexane cracking experiments information about the initial activity and the deactivation were obtained. Combination of the results of both methods led to a relation between the initial activity and the amount of strong acid sites. However, it was impossible to relate the deactivation with one of the acidic properties.

For example, way finding is believed to be strongly dependent on the lay-out of the building and seems to be hardly dependent on (escape) route signs. Though some aspects are investigated, it is not discussed at great length. In particular there is little insight in how persons find their escape route, and how this process can be supported with lay-out and design measures has been hardly examined. Thus, there is need for insight in the decision-making processes which evacuees pass through. In this paper are the results presented of 83 evacuation experiments in a hotel building at night. The main focus of the study is on way finding during fire evacuation. In the evacuation experiments we investigated the possible influence of smoke and low placed exit signs on the human fire response performance. The experiments are carried out with a traditional research method, namely the registration and evaluation of unannounced fire drills. The study is conducted as part of the validation of a new research method that makes use of serious gaming. The results of the study suggest that smoke has influence on the route choice: when no smoke is perceptible the majority of the participants escape via the main exit and when smoke blocks the route towards the main exit, the majority of the participants escape via the fire exit. Furthermore, low placed exit signs appear to have a positive influence on the use of the nearest fire exit. The personal feature of prior knowledge of the surroundings (or type of surroundings) is also found to have a positive influence on the use of the nearest fire exit. Self-assessments and interviews after a fire evacuation are found to be a disputable method for research on human behaviour in fire. A real-time observation of the people's behaviour during evacuation is considered to give more reliable results.

The fire risk is based on human behavior and on the determinants of a safe evacuation of occupants during a fire. An extensive review of literature on human behavior in fires revealed the determinants for fire safety engineering with regard to the survival of occupants. In this paper the determinants are set out for the assessment of fire risk of in particular high-rise buildings.

The possibilities of virtual reality for studying human behaviour in fires are so far hardly adopted by researchers. Nevertheless, the application of a behavioural assessment and research tool (BART) in virtual reality is expected to be a valuable supplement on the existing research methods. The innovative instrument will be validated by comparing the results of experiments in a virtual environment with results of the same experiments in real life. In this paper some results of case studies on evacuation behaviour in a real hotel building, as well as in a virtual hotel building in BART are given. The participants' route choice, pre-movement time, pre-evacuation behaviour, movement time and evacuation behaviour are part of the analysis in the paper.
