The purpose with this report is to calculate the flash point for alcohols that are mixed with water. This report describes how the flash point can be calculated. During the work with the report some experimental work has been done to verify the theoretical values. Some deviation between the theoretical and experimental values was established. The phenomenon flamespread over a fluid surface has als

Studien som ligger till grund för rapporten har som syfte att utvärdera en metod att med hjälp av en masspektrometer mäta lokala värden för bränsleluftblandningar i realtid. Metoden bygger på att ett litet prov kontinuerligt sugs genom en reaktor med ett överskott på syre och därefter genom en masspektrometer. I reaktorn oxideras allt bränsle till koldioxid och vatten. I masspektrometern mäts däre

Hög personalomsättning har varit och är fortfarande ett stort problem inom ett flertal branscher. Tidigare forskning har visat på negativa konsekvenser såsom ekonomiska kostnader och ojämn kvalité i arbetet som utförts. Intressant var därför att undersöka ett företag inom en av branscherna med hög personalomsättning för att se vad konsekvensen innebar för företaget, samt vilka faktorer som påverka

Risk evaluation of Kemicentrum, Lund, Sweden. Risk analysis, assessment and improvements on how to make the handling with flammable substances safer. The risk analysis covers the consequences and probabilities of large incidents with flammable liquids or gases. The risk level is compared with risk criteria made by Kemicentrum and the demands of the legislation in Sweden. (Swedish)

The aim of this report is to carry out a risk assessment for a company, DuPont Chemoswed, and to analyse how to present and evaluate risk. A new method of how to present and evaluate risk is composed, which is suitable for plants like DuPont Chemoswed. (Swedish)

This report identifies and estimates the risks in areas of security, health and environment, which are connected to the activity at the oil depot Lucerna in Västervik. Policy of risk management at the oil depot is being discussed. CPQRA methods to present individual and societal risk are used. Several uncertainty analyses are presented. By using the same analysis structure as in the report it can,

The aim for our project is to examine natural disasters contribution to the European Unions risk situation. Further on the project will describe co-ordination and organization connected to rescue services in occurrence of a natural disaster. With statistics from occurred natural disasters and their consequences, the expected risk in a future perspective will be calculated. The purpose with the pro

This report contains a risk analysis for transportation of dangerous substances within Stockholm northern region. The analysis refers to transportation by road and railroad. In order to estimate the danger these transports will have on the society, computer-aided calculations as well as hand calculations have been made. Conclusions and suggestions how to increase the safety level are made in this

The aim of this report is to present a proposal of how to derive input parameters to risk analysis regarding fires in buildings, with consideration taken to uncertainty. A risk analysis method of how to calculate and present risk, also with consideration taken to the uncertainty, is presented. The method is also used in an example. (Swedish)

The aim of this report is to evaluate fire risks onboard the Swedish stealth naval vessel Visby. By means of quantitative risk analysis methods including uncertainty analysis with Monte Carlo simulation together with zone model fire simulations, the risk, expressed as probability of component damage, is assessed. Also, a CFD simulation of an accommodation cabin is carried out. Finally the report c

This report describes the problems with fire safety in high rise buildings. A quantitative risk analysis has been carried out for a 24 stories high building. The level of risk is presented by F/N curves.

A model, BrandFeldt-model, is developed to decide if a component's damage criterion will be met as a consequence of fire. The component is placed in an adjoining room to the fire room, the only opening between the two rooms is a door (opened or closed).

This report contains a quantitative as well as a qualitative risk analysis of smoke control system in accommodation areas aboard large passenger ships. A discussion of the current prescriptive rules in SOLAS and the introduction of performance based design is made. Finally, areas of further research are suggested. (English)

This report describes the methodology for performing a quantitative risk analysis for a unidirectional road tunnel. By using representative accident scenarios, a basic queue model and performing an evacuation analysis the amount of casualties for each scenario can be estimated. By using the described methodology it gives the decision-makers a good idea of the risk level in the tunnel. The results

This report discusses the organizational influences on protection systems which influence the overall risk level. A number of projects concerning the effect of organizational factors on risk have been studied. A model showing the organizational influences on fire and business interruption following mainly fires have been produced. Projects relating to risk management in small SMEs have been studie

This report is an analysis of the personal safety and the administration of maintenance work at the nuclear power plant of OKG. The analysis is divided into four sections: admini- stration, radiology, fire and evacuation along with the conventional working environment. The analysis includes literature studies, visits to the plant, interviews of personnel, Prelimi- nary Hazard Analyses, and review

In this report, methods for risk and vulnerability analysis of technological infrastructure and transport are examined. Fault Tree Analysis, Event Tree Analysis, and QRA can, along with Anticipatory Failure Determination, Hierarchical Holographic Modelling, and System Action Management, be used as methods for risk and vulnerability analysis of technical infrastructure. For risk and vulnerability a
