In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.

The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.

The aim of this project is to study the work that has been done by the youth welfare to prevent accidents and to increase the preparedness in case of fire. Further the aim is to develop a basis to improve the interaction between the fire services and the youth welfare. The conclusions that were made during the project can be used to increase the safety of the environment that estates by the youth welfare..

The aim of this report is to improve the fire safety at Hallsta Paper Mill in Hallstavik, Sweden. In order to do so large parts of a fire-protection management system for the paper mill has been created. The report begins with giving a general description of management structures and fire-protection management systems. An account is given for how management structures are designed, and how they should be implemented, maintained and updated. Thereafter follows a description of what routines and instructions should be included in a fire-protection management system..

Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

The purpose of this report is to collect, compile and complement the scientific and experience based knowledge concerning high pressure fire fighting today. The goal is to produce a decision data for the Rescue Service concerning the use of high pressure systems for fire fighting. Focus is on hose reel high pressure systems but other systems are discussed too. The report begins by describing the technical properties of the different systems. Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

The purpose of this report is to study the relationship between the rescue service fire prevention activities and the number of arson fires in schools. An objective of the project is also to investi-gate the need of developing national methods for fire prevention. The results are based on a questionnaire study among 35 fire departments and further interviews with five of them. The results indicate that there is a relationship between the rescue service fire prevention activities and the number of arson fires in schools. The relationship is positive in the sense that arson fires in schools decrease with increasing prevention activities.

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..

Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.
