This master thesis was written for Arla Foods and the result of the thesisserves to gain Arla Foods in its work with chemical hazardous and to bringnew academic results. The thesis aims to create a common methodology forrisk analysis with the handling of chemicals.The theories displayed in this thesis focuses on different risk managementmethods in order to build up a framework out of which a risk management toolwas created. The main primary data source consists of interviews held withemployees within Arla Foods at different facilities.The risk management tool can be found in appendix K.Available recommendations for how to evaluate risks with chemicals can befound at appropriate government agencies. These recommendations aredrawn up to suite small and medium enterprises and therefore are to narrowto make a good foundation for analysing chemical risks at large companies.With the legislation and government demands in mind, a tool has beencreated to fit a large company?s needs when managing chemical risks.
Simulering av översvämningar i Nedre Dalälven
Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.
Risk för exponering av växtskyddsmedel i växthusmiljö
Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.
Risks Related to the Maritime Transportation of Oil and Gas (mainly Crude oil, LPG, and LNG) -A Conceptual Study and Empirical Outlook on the Baltic Sea and UK Territorial Waters to Mitigate Risks
Transportation of oil and gas by the Sea characterizes challenges from a safety viewpoint. In this type of transportation, different sizes of special tankers carrying oil and gas. The marine transportation of these scarce natural riches is involved with risks and hazards, which may lead to many losses; for instance, wasting oil and gas, injuries of people, damaging ships and properties, and damaging environment. The main purpose of this thesis is to evaluate the risks, hazards, and accidents during transportation of oil and gas (mainly Crude Oil, liquefied petroleum gas, and Liquefied natural gas) by the Sea with concentrating on transport safety. Hence, a better understanding of these risks and hazards can contribute to decrease of addressed losses.This study is carried out on risks associated with maritime transportation of oil and gas starting with describing the general casual chain (dealing with causes, incidents, accidents and consequences/causalities), continuing with describing risk analysis techniques (including event tree analysis and fault tree analysis) and risk control measures/options, and finally implementing aforesaid investigations on real data from two areas; namely UK territorial waters and the Baltic Sea.In this study, the results of analyzing data from 1991 to 2010 in UK territorial waters revealed that collision and grounding were two most common accidents in terms of crude oil tankers, LPG and LNG carriers in which 44% of all accidents were equally divided between collision and grounding.
Höjning av vattennivån i Mälaren : Ett hot mot Stockholms centrala delar vid en framtida klimatförändring?
In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.
HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder
On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.
Varningssystem för översvämningar orsakade av vårflöden och kraftig nederbörd
Översvämningar förekommer regelbundet på stora delar av jordklotet. Utgående från de klimatförändringar vi ser idag med, bland annat, kraftigare och intensivare nederbörd är det troligt att det blir fler och större översvämningar framöver. Områden som inte tidigare varit översvämmade kan komma att bli översvämmande. Varje land eller område med regelbundna översvämningar har någon form av varningssystem. Översikter över olika typer av system för att varna för översvämningar är svåra att finna. Syftet med denna uppsats är att:Undersöka viktiga principer för effektiva varningssystem för översvämningar som orsakas av kraftig nederbörd och/eller vårflöden.Skapa en systematisk och strukturerad sammanställning över nuvarande system för att varna för översvämningar orsakade av kraftig nederbörd och/eller vårflöden.Ge praktiska exempel på några svenska kommuners system för att varna för översvämningar. Litteratur- och internetsökningar kring varningssystem för översvämningar samt intervjuer med ?översvämningsansvariga? i Ödeshög och Vetlanda kommuner utgör grunden för informationen i denna uppsats. Exempel på olika typer av varningssystem för översvämningar presenteras.
Översvämningsrisker i Sverige- en kunskapsöversikt
Översvämningar är ett stort problem på flera håll i Sverige och klimatförändringarna väntas förvärra situationen i vissa delar av landet. I syfte att strukturera arbetet med översvämningsrisker togs översvämningsdirektivet (2007:60:EG) fram i EU år 2007. Direktivet genomförs som förordning (SFS 2009:956) i Sverige och denna infördes i svensk lagstiftning den 26 november 2009. Enligt förordningen om översvämningsrisker har Myndigheten för Samhällsskydd och Beredskap en viktig roll då de ska utföra den preliminära bedömningen av översvämningsrisker, bl.a. genom framtagande av kartor som redovisar översvämningshotade områden.
"...som ett trappräcke i en brant, brant trappa" : En religionspsykologisk studie av riter och kultur i copingprocesser hos drabbade av tsunamikatastrofen i Thailand 2004
Coping theory asks what the cognitive and behavioral patterns of individuals dealing with stress are. This essay includes, besides the perspective of the psychology of religion, theories of culture and ritual in exploring two Swedes coping with the natural disaster in Thailand year 2004. The vacation paradise was struck by an enormous flood wave, called a tsunami, causing vast destruction and the death of over 200.000 people. Among these 543 were Swedes on vacation. When a disaster of such measures happens, what kind of stress does it cause? How do you cope? Are religion and ritual important? What is the function of the culture in the copingprocess? Using hermeneutical analysis this essay interprets the material from two books by Swedes, who not only experienced the disaster, but lost two children and husband and wife in the flood wave.
Katastrofal rapportering : En kritisk diskursanalys av svenska dagstidningars rapportering om jordbävningen i Haiti respektive översvämningen i Pakistan 2010
This study deals with the distinct difference in media attention the earthquake-disaster in Haiti and the flood-disaster in Pakistan got in 2010. There may be many reasons to this divergence, but this study focuses on how news articles can create compassion. This study, with its critical perspective, examines how two daily papers in Sweden portray the suffering of the victims of the catastrophes in Haiti and Pakistan, and create compassion for them. Furthermore it asks the question who benefits from the newspaper?s description of human suffering in the third world. The result shows that the manner of which Swedish daily newspapers report from the catastrophe in Haiti creates an emotional involvement, which most likely leads to compassion. Furthermore it shows potential to lead the readers to identify with the suffering people in Haiti. The Swedish daily newspapers report of the catastrophe in Pakistan on the other hand, does not involve the reader on an emotional level, but gives them the role of a spectator.

Much of the information gathered for the report comes from interviews with personnel working in and with the military rescue services. The overall conclusion is that the basic conditions for a good ARFF tactic are there, but a lot needs to be improved and optimized..
Utredning och uppföljning av adoptionshundars situation
There are some hazards associated with mediating dogs for adoption to Sweden from foreigncountries. Contagion is considered to be one of them, but this report focuses solely on what adoptionsmay signify to the dogs concerning animal welfare. The aim of this study is to investigate how thebusiness in Sweden is run and what this can imply to the adopted dogs. Websites of the organizationswhich perform mediation of dogs, has been examined to show which information is available. A webquestionnaire was sent to these organizations to learn more about their standard procedure.

Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara
The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
