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.

As the ability to computerize processes and tasks increase, the proliferation of complex systems in our society continues. How these systems are deployed in the organizations where they are meant to be utilized has been shown to have a large impact on how well they function.In January of 2011 the Enköping hospital initiated the deployment of an IT-support for drug management, a module in the general health care system Cambio COSMIC. Other health care providers in the county, and in the rest of Sweden, have had mixed feelings toward the module. Some have outright refused the module, claiming that it is detrimental to patient safety. One of the arguments for deploying the module in Enköping, however, was that it was needed to improve patient safety.The Enköping hospital is considered to be a well organized institution with good leadership and earlier good experiences regarding IT-systems.

Stockholm city has recently raised its ambitions for bicycle traffic, the goal is to achieve a larger andsafer bicycle traffic. But cyclists are more vulnerable on the roads than other vehicle users because of the lack of protection. This means that a large proportion of road safety for cyclists is based on the design of the traffic environment. Since most serious bicycle accidents are those that occur in conflict with motor vehicles, and the majority of these accidents occur at intersections, these areas are of great importance forcyclist?s safety.The  purpose  of  this  paper  is  to  highlight  bicycle  accidents  at  intersections  and  to  suggest improvements  in three accident-prone junctions  in Stockholm.  This is  achieved  by  the study of accident statistics, literature and finally three case studies.The literature study focused on cyclists, traffic safety and traffic safety measures.

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 aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

In my essay I'm studying what aspects of the school environment that influences the pupils experience of safety and what aspects that strengthens the experience of safety. I'm introducing three different dilemmas from three different places in the school environment. The three dilemmas have that in common that they focus on safety. I'm introducing the after-school centre commission according to the National Agency for Education, presenting results and theories from various researchers and authors about how you can work with safety regarding children's development and learning. My conclusion is that safety is a very important aspect when it comes to learning and for the overall development of children.

Safety in the construction industry has become a question of top priority in recent years. Despite a massive investment of time, money and knowledge, the occur-rence of fatal accidents in Sweden alone is around one a month.The purpose of this study is therefore to improve the safety on the construction site. By an examination of the role of the safety agents and their cooperation with the construction workers and supervisors as well as examine how safety agents can improve safety on the construction site, which is the goal of the study.Four questions were formulated based on the purpose and the goal of the study.The methods used to answer the questions were a questionnaire survey, multiple interviews, a literature review and a document analysis.The report describes the safety agent?s role as a complex one with many different tasks. The role of the safety agents is regulated in the health and safety law, but it can sometimes be difficult to interpret and the agents can therefore interpret their role differently.

Municipal safety work is an issue frequently discussed. The new legislation about accident prevention obeys the Swedish municipality to present an action program for accident prevention. In Borlänge municipality there has been no sanctioned proposal for a program. This report presents the problems found and gives proposals for improvements in the future safety work. The guiding words should be unambiguousness, able to control and not too complicated.

Fall accidents are a big problem in the construction industry today and stand forapproximately 23% of all accidents. Skanska is a construction company that has avision toachieve zero accidents. Eliminating fall accidents is one step on the way towards theirvision. The state of Skanskas fall safety has been analyzed in this thesis to show whichimprovements are possible in fall safety.A literature study has been performed in which Arbetsmiljöverkets (The Swedishwork environment authority?s) laws and rules, together with Skanskas own rules havebeen studied.

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 accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment.

The purpose of this study was to depict some elderly people?s experiences of personal safety alarms. Furthermore, the aim was to look into whether there is any difference in experience between men and women and depending on their level of care. Using a qualitative method, semi-structured interviews were carried out with eight elderly people; six women and two men. The main questions of the study were: How do the elderly people experience the practical use of personal safety alarms? In what ways, if any, do the elderly people experience that the personal safety alarm has changed their daily life? In what ways do the elderly people experience that the personal safety alarm effects their ability to stay in their own home? A cognitive perspective was mainly used to analyze the results.

Building Automation Systems in commercial buildings are often designed and installed by different contractors, using equipment and components from different manufacturers. The lack of an accepted communication standard has resulted in a few different standards. Many manufacturers of building automation systems only support one, a few or none of these standards, while developing proprietary system solutions. Regin, who develop such equipment, are planning to adopt an open communication protocol specially designed for building automation - BACnet. As a step in that direction this thesis was announced with the purpose to investigate the possibility to implement BACnet in one of their products and to gain more knowledge of the BACnet protocol.

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

Quality Control is a term often used within production and is referring to managing processes so they produce capable products. Within Quality Control, process capability index is a common measure to oversee processes. Safety Region Plots were introduced to do this graphically. In Albing & Vännman (2010) the concept of Safety Region Plots is expanded to incorporate an elliptical shape. The method of Elliptical Safety Region Plots assumes a normally distributed data.
