The report aims at quantifying vulnerability of lakes by multiple linear regression, in which transparency of the water is used as a proxy for vulnerability and parameters such as area and depth of the lake as independent descriptors. Data was acquired from Swedish environmental monitoring programs. The analysis results in a model that can be used to predict this trend and thus predict the vulnera
This master thesis shows how microbial concentrations in raw water can be assessed by scenario modelling of microbial releases from known microbial sources. In this thesis an inventory of potential microbial sources in eastern Mälaren has been performed and 7 major sources of microbial pollution have been identified. The distribution modelling program SeaTrack Östra Mälaren has been used to model
The performance-based codes currently used for design of fire resistance of structural members are, implicitly or explicitly, based on maintaining a certain risk level. The risk level takes into account the potential injuries and casualties if structural collapse should occur in case of fire. Once the design is made, the risk level is not stated explicitly. A risk based design method is presented
Today several Swedish house-building companies are developing concepts based on industrialised house-building principles, due to problems with quality and delays. Skanska has a concept called ModernaHus that is using industrialised principles. In this report, the main purpose was to identify and analyse risks in the part of ModernaHus where concept documents are created and examined. This part is
This master ́s thesis investigates how the seasonal varying number of temporary visitors affects the number of emergency rescue efforts in a municipality. According to the Civil Protection Act municipalities should take varying risks into account. Also the result presented in this report indicates that all municipalities, and therefore BeRädd, should take this issue into account. A flow chart is p
This master thesis presents a qualitative model for performing a due diligence analysis of non- financial risks and their management, the DANFiRM model. The model includes a thinking process and a working procedure for identifying and evaluating the current non-financial risk exposure at the target enterprise and further required measures for altering risk exposure and risk management activities t
The aim of this master thesis is to present a risk assessment method to evaluate fire safety in high rise buildings. The method is essentially based on international building regulations and handbooks, interviews with Boverket (the Swedish National Board of Housing, Building and Planning) and interviews with the fire and rescue service. Two case studies have been carried out to investigate how ris
The purpose with this master thesis was to identify which problems that were related to the implementation of AFS 2001:1, examine what they were caused by and to some extent come up with solutions to the problems. In order to do this a feasibility study, a literature study and five interviews with people working with AFS 2001:1 were done. The people who got interviewed work in one large and one li
The aim of the thesis is to bring clarity to what extent the routines for risk management in different divisions comply with the ones used at OKG AB as a whole. A mapping of the risk management was made through interviews with members of staff. It was observed that a common risk identification method at OKG would serve many purposes. Literature on COSO’s framework for Enterprise Risk Management an
Today hazard studies are a self evident part of a project plan while creating a new process or making changes in an existing one in the chemical industry. Therefore it is important to make the hazard studies as efficient as possible. The objective for this thesis was to optimise the hazard study processes based on the main methods presently used at Neste Oil Oyj, Neste Jacobs Oy and Borealis Polym
This essay describes a comparison method that SÄRF can use to work in a simpler way to describe how the protection against accidents is within its area of activity. The method assume from the IDA-tool which is a tool The Swedish Rescue Services Agency has developed so the Swedish municipalities should be able to compare their own protection against accidents.
This report describes the differences between a risk analysis and a vulnerability analysis, when applied to a Flue Gas Desulphurisation (FGD) facility. A Preliminary risk analysis complemented by an Event Tree analysis is compared with An App-roach to Vulnerability Analysis of Complex Industrial Systems by Einarsson and Rausand (1998). The focus of this report is to demonstrate the different steps
In November 2004, Valdivia Cellulose Pulp Plant started operating in San Pedro de la Mariquina, 56 kilometers north-west of Valdivia in southern Chile. A few months later a decrease in the population of the Black Necked Swans (Cygnus melancoryphus) in the Carlos Anwandter Sanctuary, near the discharging point of the mill, was discovered. The aim of the thesis was to evaluate three alternative disc
According to the legislation for accident prevention and protection, which took affect January 1st 2004, all Swedish municipalities have to establish plans of actions for accident prevention and the fire service. Municipal risk analyses should constitute the foundations for these plans of actions. The purpose of this report is to describe and meet the requirements on municipal risk and vulnerabili
This master of thesis evaluates three methods for classification of areas where combustible dusts are or may be present. The methods have been applied to fictitious plant where chipboards are pro- duced. Current European directives that concern combustible dusts are also evaluated. The aim of this report is to accomplish a guiding work methodology for handling of combustible dust in the process in
The use of operating procedures at a nuclear power plant is of great importance. But improper composed procedures will increase the probability for mistakes. An inspection of the operating work at Ringhals AB carried out by WANO, has shown shortages in the way procedures are used. WANO suggests that procedures should be graded according to their importance of safety for the facility and for usage.
The development of modern enterprises goes toward more complex supply chains with many links and worldwide transportation. The trend of using centralized warehousing as logistic setup has grown more popular during the last years. This development has created new risks and implied increased vulnerabilities for many enterprises. To manage these issues the area of Business Continuity Management has g
The offshore industry means high risk activities on a daily basis and with a location far away from solid ground and handling large amount of flammable substances, these are two strong reasons that make it important to keep a high level of safety onboard. One of these safety measures is passive fire protection (PFP), in this report this means the surface coating (Chartek) protecting the load beari
The main objective of this master’s thesis is to construct a model, which can be applied on a region to investigate the possible future climate changes. This investigation is intended to lead to an analysis of the region’s changing risks regarding natural hazards affected by climate change. The hazards investigated are hydrological and climatological hazards and consist of cyclone, tornado and flo
