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
In this report networks of cooperation in crisis management are developed. The developed networks show the participant organisations in crisis management and on which level of decision they act. The networks will serve as a foundation for developing exercises in crisis management, but also as a foundation to establish contacts of cooperation in crisis management. A discussion of problems in crisis
This report considers how Mälardalens flood group should work to be able to handle county exceeding risks and vulnerabilities. A model is created which describes how to handle county exceeding risks and vulnerabilities. In the report it is also suggested how Mälardalens flood group should be organized to make the handling process work.
The new Civil Protection Act takes a more holistic view at accident prevention and protection than previous fire and safety regulations. The level of detailed regulation has decreased and national performance objectives have been formulated instead. The main purpose of this report is to present proposals for how municipalities, systematically and effectively, can plan and conduct inspection activi
The aim of this report is to make it easier for companies within the wooden industry to start with and improve their systematic fire protection. It hopefully also helps out keeping the documentation at a high level. For this purpose a model has been created. The model is based on the internal and external demands this type of industry is living with. Also the specific needs and opportunities have
The concept of intake fraction (iF) relates the emitted amount of a particular chemical to the subsequent human intake of that substance. Intake fractions have been calculated for more than 300 substances, spanning a range of up to seven orders of magnitude. It has furthermore been suggested that intake fractions can be estimated based on a few properties of the chemical. In this study, the follow
The Swedish system for crisis management is changing. Among other things, this has resulted in the law (2002:833) concerning extraordinary events in times of peace in municipalities and county councils, which states that municipalities must produce a plan for the management of extraordinary events. In this thesis, a hypothesis concerning how this plan can be based on risk- and vulnerability analys
Based on a new Swedish legislation for accident prevention and protection, this report is thought to be a guidance of making a municipality accident prevention programme. This work is following the process introduced by the Swedish Rescue Service Agency, Räddningsverket.
The purpose of this Master’s thesis was to investigate which factors influence the size of loss, insured by If, that occurred as a result of fire or explosion. Further on, this information shall be implemented at If to gain a better understanding towards risk. This to facilitate the assessment of insurance premium and reinsurance requirement.
This report contains a mapping of the different types of goods imported into Sweden by air during 2004. The process of the collection of statistical data resulted in a model. The model was developed with the purpose to make future updates easier and more accurate. Finally, the report contains a vulnerability analysis for the supply chain of pharmaceuticals in Sweden. The role of aviation was taken
The base of the work is the standard IEC 61511 “Functional Safety – Safety Instrumented Systems for the Process Industry Sector”. Developing a method for Hydro Polymers to decide a suitable Safety Integrity Level, SIL, for the safety instrumented system is the purpose of this thesis project. Assigning a SIL to the process is one way to handle the risk assessment and make the process adequately saf
The producing of safe products is very important for the food industry today due to increasing awareness of the consumers and competition in the market. To reduce the risk of pathogenic bacteria in the food industry a structured decision analysis is needed. The purpose of the thesis is to investigate which hazardous events that have occurred in the food industry, in which way these events best are
The aim of the thesis is to present a framework for risk management at Trelleborg AB. In doing that a literature study concerning what constitutes good risk management has been performed. Several useful guidelines for how good risk management should be conducted were identified. Risk management documents at Trelleborg were evaluated using these guidelines. Furthermore, complementary interviews wit
This report evaluates USAR (urban search and rescue) search methods and technical equipment that are in use today by international USAR teams. In addition, improvements to both the search equipment and methods and to USAR in general are considered.
This master thesis presents a framework, aimed at assessing fire risk in large automated warehouses. The International Electrotechnical Commission’s (IEC) framework, Risk analysis of technological systems, provides the base, as to the functions of a risk analysis framework and this is subsequently adopted and expanded to better suit the fire risk analysis in high-bay warehouses. The framework pres
