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
The purpose with this report is twofold. 1) To examine the safety-work in Swedish communities and 2) how progressive changes can be integrated into the present work. The aim is to counsel community risk- and safety work through: - Describing different safety actors involved in the areas of responsibility and cooperation. - Give suggestions on present models to achieve safe communities. - Summari
The aim of this project is to create basis for streamlining the risk management process for health care activities within Västra Götalandsregionen. The scope of the project is to develop a framework for risk management regarding health care activities and to perform a survey of the present situation, with respect to the developed framework, on a couple of health care facilities. Conclusions are ma
Currently many Swedish municipalities have big problems with increasing damage costs and difficulties in getting good insurance solutions. Therefore the purpose of this report is to give a proposal of a model for municipal safety management in Gothenburg. This has been achieved by studying statistics and by doing interviews concerning the safety culture in different municipal activities. The most
This report is comparing about ten different routes for transportation of dangerous goods to the harbour area in the city of Helsingborg in southern of Sweden. This is done by the use of three different methods for risk analysis. The report is pointing out one of the alternative routes as the best regarding societal risk and individual risk. A comparison is also made between the three different me
This report considers improvements in Swedish Rescue Service Agency’s obser- vation activity on occurred accidents. A model is constructed to develop the work for observers and decisions-makers.
The aim of this report is to present conclusions about factors of great importance for the evacuation efficiency from underground spaces such as road or train tunnels. Quantified information about the duration of different stages in the evacuation process is presented as well as conclusions about means to fasten the evacuation process. Of special interest from a risk management perspective is the
Based on a new Swedish legislation for accident prevention and protection the support of the establishment of municipality accident prevention programs with documented basic data sets for decision-making is discussed. A division into four documents of basic data sets is proposed. A process is projected for the production, decree and compliment of municipal accident prevention programmes and the do
The aim of this project is to make a model which could be used during risk identification in swedish underground stations. The model is based on a risk identification in T-centralen, Stockholm and will in a foreseeable way structure the risk sources that can affect personal safety. There will be suggestions concerning preventive measures in an underground station, both material and organizational.
The aim of this report is to survey the risks connected with home for old people to be able to enhance security and decrease the inherent risks. The goal is to create a tool that will facilitate working with risk management at home for old people, and thus be able to increase security in daily life for the people who live there as well as for personnel and visitors. The starting point of this repo
This project has resulted in an activity suited model for risk manage- ment. The objective is for the report and proposed model, to constitute a framework to the Swedish Rescue Services Agency (SRSA) as how to carry on risk management, well suited to its purpose of managing staff safety and security in humanitarian relief operations. The report con- tains an analysis of the composite of problems,
Investments in risk reduction are very complex with many factors that affect the overall profitability of the investment. Therefore, different models and approaches are used in the decision making process. An analysis of the problem is then made according to certain basic rules. When the risk situation is evaluated in this manner the decisions that are made are rational and consistent. By using th
This thesis is about how risks in Hvalfjörður Tunnel can or should perhaps be managed. Risk from collisions, vehicle fire and vehicles transporting dangerous goods accidents in the tunnel were quantified by using Probabilistic Risk Analysis (PRA) procedure. Frequencies were estimated using mostly historical data. Models to estimate consequences from these risks were then built by calculating physi
This report has resulted in a method to evaluate and map the safety culture within a company. The method consists of two templates. One template, the assessment template, which works as a reference point and one presentation template where simply the facts and status of the company will be presented and evaluated compared to the assessment template. Safety culture relates to attitudes, behaviour,
For a very long time the municipal fire services in Sweden have been formed due to tradition and different laws. This design does not take the actual risks in the municipal into consideration. The purpose of this report is therefore to create a model for designing municipal fire services. This model will take more factors into consideration than the population structure as has been done before.
The main objective is to investigate if hypoxic environment is a viable fire prevention method in occupied enclosures. Hypoxic environment is a technique where the oxygen concentration is constantly reduced inside an enclosure. The purpose with the technique is to prevent fires and in case of a fire reduce the risk for fire spreading. The risks are studied and different reduced oxygen concentratio
Using fireworks is a tradition in Sweden, in conjunction with celebration of New Year, Easter and last day of April. Fireworks are also used in conjunction with concerts, displays and sport events. The usage of fireworks is associated with risks for people, the environment and property. The purpose of this report is to study the risks for people that are caused by the handling of fireworks and the
