This report deals with fully developed fires in compartments where the boundary structure is made of mineral wool and plasterboard. The project was initiated due to new Swedish regulations (BBR 94) that allow buildings with wood structure to be built more than two storeys high. The temperature-timecurves in this report are computed according to authorized methods used in Sweden (method I and metho
This paper deals with the concept of trade-off and comparisons between different fire protection alternatives. Fire protection regulations concerning the building process and the nuclear power industry are being discussed. Different methods of decision analysis as well as risk analysis and uncertainty analysis are presented. A method of how to make quantitative risk and cost assessment between dif
The aim of this report has been to present a risk analysis method that can be used when the fire risk in a given industry is to be evaluated. The risk is presented as the expected monetary loss during one year due to fire. A way of comparing different fire protection strategies with respect to the expected monetary loss due to fire and the cost due to the fire protection installation during one ye
The Fire Risk Index Method is a tool for assessing fire safety in multi-storey apartment buildings. This report contains a description of how Version 1.2 of the Fire Risk Index Method was developed. The terminology frequently used in the development process of the method is also explained. The use of the Fire Risk Index Method is described and illustrated by an example. The method is applied to an
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).
