Occupational Exposure Limits (OELs) are used as an important regulatory instrument to protect workers’ health from adverse effects of chemical exposures. The OELs mirror the outcome of the risk assessment and risk management performed by the standard setting actor. In paper I the OELs established by 18 different organisations or national regulatory agencies from the industrialised world were compared. The comparison concerned: (1) what chemicals have been selected and (2) the average level of exposure limits for all chemicals. In paper II the OELs established by 7 different national regulatory agencies of EU member states are compared to those of the European Commission (EC). In addition to the same comparisons as performed in the first study a comparison level was introduced (3) the similarity between the OELs of these EU member states and the OELs recommended by the EC.

List of OELs were collected through the web-pages of, and e-mail communication with the standard-setting agencies. The selection of agencies was determined by availability of the lists. The database of paper I contains OELs for a total of 1341 substances; of these 25 substances have OELs from all 18 organisations while more than one third of the substances are only regulated by one organisation alone. In paper II this database was narrowed down to the European perspective. The average level of OELs differs substantially between organisations; the US OSHA exposure limits are (on average) nearly 40 % higher than those of Poland. Also within Europe there was a nearly as large difference. The average level of lists tends to decrease over time, although there are exceptions to this. The similarity index in paper II indicates that the exposure limits of EU member states are converging towards the European Commission’s recommended OELs. These two studies also showed that OELs for the same substance can vary significantly between different standard-setters. The work presented in paper III identifies steps in the risk assessment that could account for these differences. Substances for which the level of OELs vary by a factor of 100 or more were identified and their documentation sought for further scrutiny. Differences in the identification of the critical effect could explain the different level of the OELs for half of the substances. The results reported in paper III also confirm the tendency of older OELs generally being higher. Furthermore, several OELs were more than 30 years old and were based on out-dated knowledge. But the age of the data review could not account for all the differences in data selection, only one fifth of the documents referred to all available key studies. Also the evaluation of the key studies varied significantly.

This thesis focuses on exacerbating chemicals risk in workplaces under the background of rapid industrialization in developing countries. The overall aim is to investigate the development of regulatory tools which aim at minimizing the health risks from chemical substances in the workplace. The contents of the thesis are divided into three sections: the profile of occupational diseases in China (paper I), occupational exposure limits (paper II and III), and comparison between chemicals regulat ions in Europe and China (paper IV). Paper I presents an analysis of the development of occupational diseases in China between 2000 and 2010. The number of recorded cases of occupational diseases increased rapidly in China during this period and the majority of cases were attributable to dust and other chemicals exposures. Difficulties in diagnosis and inefficient surveillance are major impediments to the proper identification and mitigation of occupational diseases. Migrant workers are extremely vulnerable to occupational hazards. Paper II investigates the state of harmonization of OELs between twenty-five OEL systems in Europe and Asia. The majority of the investigated organizations declare themselves to have been influenced by the American Conference of Governmental Industrial Hygienists (ACGIH), and in many cases this can be empirically confirmed. However, large international differences still exist in substance selection and in the level of OELs among organizations. Paper III explores the setting of risk-based OELs on non-threshold carcinogens. Relatively few agencies set risk-based OELs. Differences exist in policy, both regarding the magnitude of risk considered as tolerable or acceptable and whether a general risk level or case-by-case substance-specific risk levels are determined. In regards to the level of the OELs both differences in science and policy contribute, and it was not possible to determine which has the larger influence.

Paper IV systematically compares the regulation systems for chemicals in the EU and China in terms of substances covered, requirement on information, risk assessment and risk management. It shows that the European and Chinese chemicals legislations are remarkably similar.The differences are larger in terms of substance coverage and data requirements than in terms of risk assessment and management. Substitution of hazardous substances is driven more by updates of the EU regulatory system than of the Chinese system.

As empresas produtoras de pedra britada têm uma atribuição fundamental para o desenvolvimento socioeconômico da população que é a produção de material básico para construção civil. A pedra britada está entre as cinco primeiras substâncias minerais com maior valor de produção, e mesmo assim, os dados de consumo per capita indicam que no país existe uma demanda latente de agregados para construção civil, representada por um alto índice de falta de moradias e por uma infra-estrutura sanitária deficiente. A crescente demanda da produção de bens minerais associada à falta de controle dos riscos ocupacionais, acentuam os problemas de saúde e segurança do trabalho na mineração. A presente dissertação aborda a avaliação da concentração de poeira contendo sílica cristalina no ambiente de trabalho em uma empresa de mineração a céu aberto produtora de brita na região metropolitana de São Paulo. Com o objetivo de estimar os riscos da exposição ocupacional à poeira de sílica cristalina foram obtidas doze amostras de poeira na fração respirável em cinco atividades realizadas na lavra de brita. As amostras de poeira respirável foram coletadas junto aos trabalhadores, utilizando-se bombas de amostragem de uso individual, ciclone Dorr-Oliver e filtros de membrana de PVC. O método analítico adotado para quantificação da sílica cristalina utilizou a técnica de espectrometria de difração de raios X. Os resultados obtidos nos processos de perfuração e britagem indicaram que os riscos de exposição à poeira são inaceitáveis. Mesmo em condições ambientais apresentando chuviscos ocasionais, a perfuratriz provida de sistema de umidificação proporcionou concentrações de poeira respirável acima dos limites de exposição. Na atividade de movimentação de rochas os resultados apresentaram riscos aceitáveis de exposição para o operador da pá carregadeira devido à cabina dispor de sistema de ar condicionado, isolando o trabalhador do meio externo.
The crushed stone companies have a fundamental attribution for the economic development and well-being of the population that is the production of basic material for civil construction. The crushed stone is between the five first mineral substances with larger production value, and even so, the consumption data per capita indicate that in the country exists a latent demand of aggregate for civil construction, represented by a high index of dwellings lack and for a deficient sanitary infrastructure. The increasing demand of the production of mineral goods associate to the lack of the risk control, accentuate the occupational safety and health problems in the mining activity. The dissertation presents the evaluations of dust concentration contend crystalline silica in the working environment in a quarry in São Paulo's metropolitan area. With the purpose of risks assessment estimation of the occupational exposure to crystalline silica were obtained twelve dust samples in the respirable mass fraction in five activities accomplished in the mining process of crushes. The respirable dust samples were collected close to the workers, using personal samplers pump, Dorr-Oliver cyclone and PVC membrane filters. The analytic method adopted for quantification of crystalline silica used X-ray diffraction spectrometry. The results obtained in the drilling and crushing processes indicated that the exposure risks to the dust are unacceptable. Even in environmental terms happening occasional fine drizzle, the drill resulted from wet system provided concentrations of respirable dust above the exposure level. In the rocks transport activity the results revealed acceptable risks of exposure for the operator of the shovel due to the cabin have air conditioner system, isolating the worker of the external area.

Att kunna arbeta med systematisk hantering av brotts-, brands- och arbetsmiljörisker är en eftertraktadkompetens. Det syns inte minst i både näringslivets och den offentliga förvaltningensarbetsannonser när man söker chefer, handläggare eller samordnare till säkerhetsavdelningar.Trots det finns mycket lite skrivet på svenska om riskhantering och riskanalys i kontexten skyddmot brott. Ännu ovanligare är litteratur som jämför riskhantering mellan brandskydd, arbetsmiljöoch brottsskydd.Bristen på litteratur påverkar även studier av riskhantering inom fysisk och organisatorisk säkerhet,i synnerhet på akademisk nivå där det i Sverige är ett relativt nytt ämne. Att flytta fram positionernaoch vidga kunskapsfältet är därför angeläget både för ämnet fysisk- och organisatorisk säkerhetsåväl som för näringslivet. Detta kandidatarbete är ett tidigt bidrag till ett ämnesområde som ser utatt växa. Genom att kartlägga engelsspråkiga handböcker och det vetenskapliga kunskapsläget inomnärliggande discipliner har arbetet haft ytterligare ett mål: att nå ut med kunskap till de som arbetarmed riskhantering i praktiken och på så sätt vidga gruppens medvetenhet och yrkeskompetens.Uppsatsens syfte är att redovisa kunskapsläget och samtidigt visa på riskhanteringsprocessensbredd och djup. Mer konkret har det skett genom att identifiera likheter och skillnader i destuderade områdenas begreppsapparater, processbeskrivningar, problem, framgångsfaktorer ochsamtidigt redovisa eventuell kritik som riktas mot riskhantering som fenomen. Resultaten visar attdet finns fler likheter än skillnader mellan både riskhanteringsprocesser som riskanalysmetoder,oavsett om syftet är att skydda mot brott, ohälsa eller brand och olyckor.Arbetet har genomförts som en deskriptiv litteratursstudie och jämförande textanalys. Riskhanteringsprocessenhar beskrivits med utgångspunkt i den generiska ISO-standarden (31000:2009,Riskhantering - Principer och riktlinjer). Tio riskanalysmetoder som täcker samtliga steg i riskbedömningsmomentethar valts ut och beskrivits. Redovisning med tillhörande analys har följtsamma ordningsföljd som standardens processbeskrivning. Materialet har kompletterats ochjämförts med facklitteratur och vetenskapliga artiklar från tre riskhanteringsområden: (1) skyddmot ohälsa i arbetsmiljön, (2) skydd mot brand och olyckor samt (3) skydd mot brott.Uppsatsen ger även exempel på den inkonsekventa begreppsanvändningen som förekommer bådemellan och inom olika discipliner som sysslar med riskhantering. En av uppsatsens slutsatser äratt det sannolikt inte går att skapa en enhetlig begreppsapparat varken inom akademin eller i denpraktiska verksamheten samtidigt som det heller inte är nödvändigt. Istället kan missförstånd undvikasgenom att tydligt och i varje enskilt fall definiera vad man avser med ett visst begrepp.
The competence to manage risks related to health, security, fire and safety is a sought-after skill.This is especially noticeable in both business and public administration job postings for therecruitment process of managers, administrators or coordinators to security departments. At thesame time there is little specialist literature available in Swedish on the subject of risk managementin the context of protecting assets and people from physical security threats. The lack of literatureaffects the study of risk management from a physical and procedural security perspective,particularly at an academic level where this is a relatively new topic. To move forward and expandthe field of knowledge is an important step, not only for the scientific community but also for theindustry. This bachelor thesis attempts to be an initial but significant contribution to a topic thatis likely to grow. By mapping what has already been published on the subject in English as wellas summing up and analyzing the scientific knowledge from similar disciplines the thesis has alsohad an additional goal: to reach out with knowledge to those dealing with risk management inpractice, and thus raising their awareness and developing their professional skills.The purpose of this study is to present the current state of knowledge and at the same time toshow the width and depth of the risk management process. This is done by identifying similaritiesand differences in definitions, process descriptions, problems and best practice of the studied areaswhile at the same time account for any criticism offered against risk management as a concept.The results show that there are more similarities than differences in the risk management processand methods regardless of whether the purpose is to protect people and assets from healthhazards, crime, fire or accidents.The paper has been conducted as a descriptive literature study and a comparative textual analysis.The risk management process has been described with reference to the generic ISO standard(31000:2009, Risk management - Principles and guidelines). Also, ten common risk analysismethods that cover all steps in the risk assessment process have been described. The narrative andrelated analysis follow the same order as the ISO-standard process description.The material has been supplemented and compared with guidelines and scientific papers from threetypes of risks management contexts: (1) health hazards, (2) fire and safety, and (3) security.The paper also provides examples of the inconsistent use of terms and definitions both between andwithin different disciplines involved in risk management. One of the conclusions of the report is thatcreating a unified, universal terminology to be used in the security context probably is impossibleas well as being not necessary. Instead, certain terminological misunderstandings can be avoided byproviding clear definitions and explanations of their meaning in each particular case.

Disasters are complex events characterized by damage to key infrastructure and population displacements into disaster shelters. Assessing the living environment in shelters during disasters is a crucial health security concern. Until now, jurisdictional knowledge and preparedness on those assessment methods, or deficiencies found in shelters is limited. A cross-sectional survey (STUSA survey) ascertained knowledge and preparedness for those assessments in all 50 states, DC, and 5 US territories. Descriptive analysis of overall knowledge and preparedness was performed. Fisher’s exact statistics analyzed differences between two groups: jurisdiction type and population size. Two logistic regression models analyzed earthquakes and hurricane risks as predictors of knowledge and preparedness. A convenience sample of state shelter assessments records (n=116) was analyzed to describe environmental health deficiencies found during selected events. Overall, 55 (98%) of jurisdictions responded (states and territories) and appeared to be knowledgeable of these assessments (states 92%, territories 100%, p = 1.000), and engaged in disaster planning with shelter partners (states 96%, territories 83%, p = 0.564). Few had shelter assessment procedures (states 53%, territories 50%, p = 1.000); or training in disaster shelter assessments (states 41%, 60% territories, p = 0.638). Knowledge or preparedness was not predicted by disaster risks, population size, and jurisdiction type in neither model. Knowledge: hurricane (Adjusted OR 0.69, 95% C.I. 0.06-7.88); earthquake (OR 0.82, 95% C.I. 0.17-4.06); and both risks (OR 1.44, 95% C.I. 0.24-8.63); preparedness model: hurricane (OR 1.91, 95% C.I. 0.06-20.69); earthquake (OR 0.47, 95% C.I. 0.7-3.17); and both risks (OR 0.50, 95% C.I. 0.06-3.94). Environmental health deficiencies documented in shelter assessments occurred mostly in: sanitation (30%); facility (17%); food (15%); and sleeping areas (12%); and during ice storms and tornadoes. More research is needed in the area of environmental health assessments of disaster shelters, particularly, in those areas that may provide better insight into the living environment of all shelter occupants and potential effects in disaster morbidity and mortality. Also, to evaluate the effectiveness and usefulness of these assessments methods and the data available on environmental health deficiencies in risk management to protect those at greater risk in shelter facilities during disasters.

The management of health and safety risks in the oil refinery tends to be centred on the collection and simulation of technical data which can then be used to make decisions on the wellbeing of the workforce as well as the refinery installations. While the number crunching in the process is immensely vital, there tends to be a problem of ignoring or, at the very least, side-lining the social-cultural values of the people dealing with health and safety risk assessment processes. The economic driver for the operation of the oil refinery tends to be more important because of the generally huge initial financial outlay, and the eventual high costs of maintenance; hence health and safety risk management should have evidence of ensuring that the installations, as well as the people that work in them, are well catered for. In the Kuwait Gulf Oil Company this problem is more evident in newer installations where lean management processes have been instituted by oil firms so that they can reduce waste in the oil refining process without compromising the occupational health and safety needs of the refinery. Therein lies the initial problem of integrating health and safety risk assessment processes because most approaches concentrate on the technical elements of waste elimination while ignoring the social-cultural factors that impact on the health and safety of the workforce. This is an exploratory piece of research that examines the impact of rational and cognitive decision theories – herein called the psychology of risk – and how they impact on the occupational health and safety systems in the oil and gas refining sector of Kuwait. The research concludes that the application of lean concepts in the oil refining process is noble in itself but it needs to be integrated with the rational and cognitive detection factors that are necessary to incorporate and support the social-cultural tendencies of the workforce. The research recommends a framework for incorporating social-cultural values in the decision making process pertaining to health and safety risk assessment in oil refining process plants. Key Words: occupational health and safety risk assessment; lean management; social-cultural values; rational and cognitive decision making; oil and gas process plants.

Introduction: Lower extremity (LE) work-related musculoskeletal disorders (WMSDs) are known to occur with cumulative exposure to occupational and personal risks. The objective of this dissertation study was to find if creating a quantifiable risk detection model for the LE was feasible. The primary product of the literature review conducted for this study resulted in focusing the attention of the model development process onto creating the initial model of the LE for assessing knee disorder risk factors. Literature Review: LE occupational disorders affect numerous industries and thousands of people each year by affecting any one of the musculoskeletal systems deemed susceptible by the occupational and personal risk factors involved. Industries known to be affected tend to have labor intensive job descriptions. Some of the numerous industry examples include mining, manufacturing, firefighting, and carpet laying. Types of WMSDs noticed by the literature include bursitis, osteoarthritis, stress fractures, tissue inflammation, and nerve entrapment. In addition to the occupationally related disorders that may develop, occupationally related discomforts were also taken into consideration by this study. Generally, both the disorders and the discomforts can be traced to either a personal or occupational risk factor or both. Personal risk factors noted by the literature include a person's physical fitness and health history (such as past injuries). Meanwhile, occupational risks can be generalized to physical postures, activities, and even joint angles. Prevalence data over a three year interval (2003-2005) has found that LE WMSDs make up on average approximately 7.5% of all the WMSD cases reported to the US Occupational Safety and Health Administration (OSHA). When the literature is refined to the information pertaining to occupational knee disorders, the mean prevalence percentage of the same three year range is about 5%. Mean cost for knee injuries were found to be $18,495 (for the year between 2003 and 2004). Methodology: Developing a risk model for the knee meant using groups of subject matter experts for model development and task hazard analysis. Sample occupational risk data also needed to be gathered for each of a series of tasks so that the model could be validated. These sample data were collected from a sample aircraft assembly plant of a US aerospace manufacturer. Results: Based on the disorder and risk data found in the literature, a knee risk assessment model was developed to utilize observational, questionnaire, and direct measure data collection methods. The final version of this study's knee model has an inventory of 11 risk factors (8 occupational and 3 personal) each with varying degrees of risk exposure thresholds (e.g., high risk, moderate risk, or minimal risk). For the occupational risk assessment portion of the model, the results of task evaluations include both an occupational risk resultant score (risk score) and a task risk level (safe or hazardous). This set of results is also available for a cumulative (whole day) assessment. The personal risk assessment portion only produces a risk resultant score. Validation of the knee risk model reveals statistically (t (34) = 1.512, p = 0.156), that it is functioning as it should and can decide between hazardous and safe tasks. Additionally, the model is also capable of analyzing tasks as a series of cumulative daily events and providing an occupational and personal risk overview for individuals. Conclusion: While the model proved to be functional to the given sample site and hypothetical situations, further studies are needed outside of the aerospace manufacturing environment to continue testing both the model's validity and applicability to other industrial environments. The iterative adjustments generated for the occupational risk portion of the model (to reduce false positives and negatives) will need additional studies that will further evaluate professional human judgment of knee risk against this model's results. Future investigations must also make subject matter experts aware of the minimal risk levels of this knee risk assessment model so that task observational results are equally comparable. Additional studies are moreover needed to assess the intimate nature between variable interactions; especially multiple model defined minimal risks within a single task.

A novel strategy was used to assess the risk to health from exposure to polycyclic aromatic hydrocarbons (PAHs), an important class of chemical carcinogens, in workers in the paving and roofing industries using bitumen. The aim was to evaluate the risk of exposure to PAHs at three different stages: these were external exposure "external dose", internal exposure "internal dose" and biological effect "biologically effective dose". The approaches used for quantifying the risk at these stages were ambient monitoring, biological monitoring and biological effect monitoring, respectively. Ambient monitoring was carried out by personal air sampling and measurement of PAH-exposure. Excretion of thioethers (a non-selective biomarker) and 1-hydroxypyrene (a selective biomarker of exposure to pyrene) in urine were determined. Urinary d-glucaric acid, sister chromatid exchange in peripheral blood lymphocytes and micronuclei in exfoliated cells were use for biological effect monitoring. Seven groups of workers were studied. These were office workers, departmental staff and manual workers who were not occupationally exposed to PAHs and who were included as controls, and two groups of payers and roofers who were exposed to bitumen fumes during their work. The ambient monitoring program revealed that concentrations of PAHs in environmental air could be as high as those found in the payers' and roofers' occupational environments. The contribution of these background levels to the external dose of the pa yers and roofers was considerable. Payers and roofers were occupationally exposed to low levels of PAHs. The PAH profile in the personal air sample of the workers was different between the two industries. This was attributed to the presence of PAH-emission sources other than hot bitumen, such as vehicle exhaust. The concentration of naphthalene measured in air samples was a good indicator for identifying the existence of these sources. The quantitative evaluation of the carcinogenic risk inherent in the external dose using the 8 hour TWA concentration as a measuring stick did not seem to be effective due to the low "noise" levels of carcinogenic PAHs present. A semi-quantitative measure of the external exposure was suggested which appeared to be a better reflection of the carcinogenic risk. Urinary thioethers are not sensitive enough to be used as a nonselective biomarker of exposure to low levels of PAHs; however, urinary 1- hydroxypyrene was a good indicator of internal exposure to pyrene and therefore PAHs in bitumen fume. The relationship between 1-hydroxypyrene in urine and specific airborne PAH-exposure indices in the results of the payers, but not the roofers, suggested that the route of exposure in the latter is mainly dermal while that in the payers is more related to respiratory uptake. This observation, however, did not agree with the subjective occupational hygiene assessment where it was observed that the roofers were closer to the source of PAH-emissions due to the nature of their job and both groups did not use any respiratory or personal protective equipment. The measurement of urinary d-glucaric acid excretion suggested, but not strongly, that hepatic enzyme activity was induced in the occupationally PAH-exposed groups in comparison to controls and reflected the internal dose of pyrene or total PAHs. These observation; however, need further investigation. Micronuclei in exfoliated epithelial cells could not be measured in these populations as insufficient bladder epithelial cells were obtained for analysis. Sister chromatid exchange in peripheral blood lymphocytes of payers and roofers was significantly elevated in comparison to control and manual worker group. The group mean frequencies of SCE were significantly correlated with the external exposure to carcinogenic PAHs. This observation suggested that sister chromatid exchange is a very sensitive cytogenetic endpoint and is useful for evaluating the risk of exposure to low levels of carcinogenic PAHs. Risk assessment, such as the one conducted in this study, allows a quantitative estimation of risk associated with long-term exposure to moderate and low levels of airborne exposure to PAHs in bitumen fume. Knowledge of dose response relationship may allow a review of current Occupational Exposure Standards (OES) and Biological Exposure Limits, which are at present either unavailable or based on poor background scientific knowledge for most PAH compounds. In this study we have suggested an Occupational Exposure Limit for PAHs based on the sum of fourteen PAH-species.

Durante o ciclo de vida dos produtos químicos, é possível que estes sejam lançados no ambiente ou ainda que sejam absorvidos por indivíduos de uma população, podendo ocorrer danos ambientais ou alterações no estado de saúde desses indivíduos expostos. Por haver a possibilidade de riscos à saúde é imprescindível investigá-los nas diversas situações possíveis de exposição, a fim de estabelecer, quando necessário, medidas preventivas ou emergenciais, visando a proteção da população e das demais espécies presentes nos compartimentos ambientais. Um dos requisitos básicos para o processo de avaliação de risco é a identificação dos perigos que os produtos químicos podem oferecer à saúde devido suas propriedades químicas e fisico-químicas. Este estudo teve como finalidade realizar um levantamento sobre a existência de informações relativas à toxicidade e comportamento no ambiente de produtos químicos fabricados, importados e ou com capacidade de produção no Brasil maior que 500 toneladas por ano, os quais não estão sendo objeto de investigação nos principais programas atualmente existentes no mundo destinados à avaliação de risco de substâncias químicas. O método proposto por este estudo possibilitou uma análise crítica da falta de informação sobre dados de produção ou importação de produtos químicos utilizados no Brasil, além de possibilitar o levantamento sobre a existência de informações toxicológicas para produtos químicos fabricados em larga escala no país. Como resultado, foi constatado que apenas 3,9 % de 461 produtos químicos possuem as informações necessárias para o processo de avaliação inicial de risco.
Chemical products during their life cycle may be absorbed by individuals of the population, consequent1y causing environmental damage or interfering in the health of the exposed individuals. Due to the possibility of health risks, it is imperative to evaluate these risks in all possible situations. If needed, prevention and emergency measures, aiming at protecting the population and the species present in the environment, should be established. A basic requirement for risk assessment is the hazard presented to health by chemical products due to their physic-chemical properties. The objective of this paper was to raise the available data related to the toxicity and the impact on the environment of high volume chemicals manufactured, imported or with a production capacity in Brazil greater than 500 t/year, that are not included in the major world programs of risk assessment. The methodology used in this paper enabled a critical analysis of the lack of data on production or imports of chemicals used in Brazil, in addition to the screening of toxicological information for high production volume chemicals produced in Brazil. As a result, it was found that only 3,9% of the 461 chemicals have the information required for a initial risk assessment.

Increasing applications of nano materials in medicine, construction, textiles, computers, and other consumer goods have lead to increasing concerns of their effect on human health and ecology during synthesis, manufacturing, use, and disposal of nano-materials. Though much scientific progress has been made in nano material synthesis, manufacturing, and application in consumer goods and other sectors such as medicine, textiles and more, not much progress has been made in understanding the adverse effects of nano materials on human health and the environment. Physical, chemical, toxicological characteristics of these nano materials and their fate in the environment are important in understanding their adverse effects on the environmental and human health. This study is aimed at developing a preliminary framework for risk assessment (RA) and risk management (RM) of nano materials based on fundamental principles of chemistry, physics, toxicology, and other related disciplines.

Occupational Exposure Limits (OELs) are used as an important regulatory instrument to protect workers’ health from adverse effects of chemical exposures. The main objective of this thesis is to study risk assessment practices in the setting of OEL in order to produce knowledge that will help improve the consistency and transparency of OELs. For the purpose of paper I a database of OELs for a total of 1341 substances was compiled. Of these, only 25 substances have OELs from all 18 included organisations while more than one third of the substances are only regulated by one organisation alone. The average level of OELs differs substantially between organisations; the US OSHA exposure limits are (on average) nearly 40 % higher than those of Poland. In paper II six EU member states’ OELs are compared to the European Commission’s OELs. Also within Europe there is a large difference concerning the average level of OELs (35%). The average level of lists tends to decrease over time, although there are exceptions to this. There are also indications that the exposure limits of EU member states are converging towards the European Commission’s OELs. The work presented in paper III identifies steps in the risk assessment that could account for the large differences in OELs for 14 different substances. Differences in the identification of the critical effect could explain the different level of the OELs for half of the substances. But the age of the data review could not account for all the differences in data selection, only one fifth of the documents referred to all available key studies. Also the evaluation of the key studies varied significantly. The aim of paper IV was to investigate how the Scientific Committee on Occupational Exposure Limits (SCOEL) of the European Commission uses assessment factors when proposing health-based indicative OELs. For only one third of the investigated OELs were explicit assessment factors given. On average the safety margin of the recommendations was 2.1 higher when an explicit assessment factor had been used. It is recommended that the SCOEL develop and adhere to a more articulate framework on the use of assessment factors. Paper V focuses on the Derived No-Effect Levels (DNELs) which are to be calculated under the new European Union REACH legislation. It is a comparison of the safety margins of 88 SCOEL recommendations with those of the corresponding worker-DNELs, derived according to the default approach as described in the REACH guidance document. Overall, the REACH safety margins were approximately six times higher than those derived from the SCOEL documentations but varied widely with REACH/SCOEL safety margin ratios ranging by two orders of magnitude, from 0.3 to 58.

Traditional methods of project management are not appropriate for complex projects anymore. Since projects are becoming increasingly complex and uncertain, interaction between activities and resources is growing in ways not considered by these methods. Nowadays, managers need more agile project management methods that are able to recognize and deal with uncertainty and to produce the expected results. Lean project management, the most recent approach of lean methodology, appears as an alternative approach capable of dealing with complexity and uncertainty. The latest investigations in the field show that traditional methods are still adequate for simple projects, while lean methods are more appropriate for complex projects. This thesis aims to investigate the nature of lean project management and to examine project risk management processes so that managers can assess the complexity of projects before their beginning and decide which method to apply in order to manage them.

ENGLISH ABSTRACT: Risk management is a widely used term meaning different things to people in different economic sectors. To some, it refers to auditing and, to others, it means Occupational Health and Safety (OHS), compliance or any risk management activity dominant in the user’s frame of reference. Risk management probably includes all these associations. Viewing this study field from different angles prevents the visualisation and grasping of the whole. Business schools do not lead the way in overcoming this fragmented study field, as an all-inclusive theory basis and course outline are not yet available. The whole is taken to be the complete answers to a list of very basic questions, namely who must do what, how, when and why, and what then. This introductory study starts with the what question. Risk management activities within a sample of companies from banking to mining and manufacturing were researched. The result is a proposed map of common risk types and sector or industry-unique risks dominant in a specific environment. Three risk management training programmes were evaluated to determine whether or not the basic questions are addressed: the UNISA Advanced Programme in Risk Management, the USB Programme in Risk Management and the Enterprise Risk Management Integrated Framework developed by COSO. These programmes were assessed to determine whether they address the practical risk management questions of who must do what, when and why, and what then. A combination of some of the strong points of the courses is proposed as a starting point for overcoming the theory gap.
AFRIKAANSE OPSOMMING: Risikobestuur is ŉ algemeen gebruikte term wat verskillende dinge vir verskillende gebruikers beteken. Vir party verwys dit na die ouditfunksie, vir ander beteken dit beroepsgesondheid en -veiligheid, wetlike voldoening of enige ander risikobestuursaktiwiteit wat deel van ŉ persoon se verwysingsraamwerk vorm. Risikobestuur sluit waarskynlik al hierdie assosiasies in. Die benadering van die studieveld vanuit verskillende verwysingspunte maak dit egter moeilik om die studieveld as geheel te sien en te begryp. Bestuurskole neem ook nie die leiding om die gefragmenteerde aard van die studieveld te oorkom nie, want ŉ omvattende teoretiese grondslag en raamwerk is nie beskikbaar nie. Die geheel word geag te wees volledige antwoorde op ŉ paar basiese vrae, naamlik wie moet wat, wanneer, hoe en wat daarna doen. Hierdie inleidende studie fokus op die wat vraagstuk. Risikobestuursaktiwiteite in ŉ steekproef van firmas vanuit die bankwese, mynwese en vervaardigingsektor word ondersoek. Die resultaat is ŉ voorgestelde raamwerk van algemene asook omgewingsunieke risikosoorte. Drie risikobestuuropleidingsprogramme, naamlik UNISA se Gevorderde Sertifikaatprogram in Risikobestuur, die USB se Risikobestuursprogram en COSO se Ondernemingswye Risikobestuursprogram, is geëvalueer om te bepaal in watter mate hulle op die praktiese risikobestuursvraagstukke, naamlik wie moet wat, wanneer, hoe en wat daarna moet doen, ingaan. ŉ Kombinasie van die verskillende kursusse se sterkpunte word uiteindelik as beginpunt vir die oorbrugging van die gaping in die teorie voorgehou.

This thesis studies the Chinese banks’ credit risk assessment using the Post Keynesian approach. We argue that bank loans are the major financial sources in emerging economies and it is uncertainty, an unquantifiable risk, rather than asymmetric information about quantifiable risk, as held by the mainstream approach, which is most important for the risk attached to credit loans, and this uncertainty is particularly important in China. With the universal existence of uncertainty, borrowers and lenders have to make decisions based on convention and experience. With regard to the nature of decision-making, this implies the importance of qualitative methods rather than quantitative methods. The current striking problem in Chinese banking is the large amount of Non-Performing Loans (NPLs) and this research aims to address the NPLs through improving credit risk management. Rather than the previous literature where Western models are introduced into China directly or with minor modification, this work advocates building on China’s conventional domestic methods to deal with uncertainty. We briefly review the background of the Chinese banking history with an evolutionary view and examine Chinese conventions in the development of the credit market. Based on an overview of this history, it is argued that Soft Budget Constraints (SBC) and the underdeveloped risk-assessing mechanism contributed to the accumulation of NPLs. Informed by Western models and experience, we have made several suggestions about rebuilding the Chinese convention of credit risk assessment, based on an analysis of publications and interviews with Chinese bankers. We also suggest some further development of the Asset Management Companies (AMCs) which are used to dispose of the NPLs.

International bodies and networks within occupational health and occupational health psychology have over the last years highlighted a pressing need to understand how research and best practices can be translated into sustainable business practice. To stimulate and support organisations in strengthening their psychosocial risk management there have been a number of initiatives, guidance and frameworks that focus on best practice principles for managing the psychosocial work environment (BSI, 2011; Leka, Jain, Cox & Kortum, 2011; WHO, 2010). An essential question is how the frameworks launched by international initiatives, frameworks and standards can be re-interpreted and adjusted to fit the language and systems of particular business contexts, such as that of the petroleum industry. To explore this issue, this research has looked at how an oil and gas company has integrated a sustainable and comprehensive system for managing psychosocial risk. This research has two aims. First, it explores how the oil and gas industry can develop and implement a psychosocial risk management system by applying research and best practice in a Norwegian oil and gas company, in order to raise awareness of how psychosocial risk management practices can be integrated into a company’s internal management system. Secondly, it aims at raising awareness and stimulate to the application and use of established knowledge at organisational and national levels in this area. In this sense, the ultimate aim of this research is to inform policy makers about what it takes to actually implement and integrate policy into company context and at the same time to promote a comprehensive approach to worker protection and the promotion of their health. In all, four studies describe aspects of how this integration process has evolved. The first study explored the development and testing of a performance indicator for psychosocial risk in the oil and gas industry (Bergh, Hinna, Leka, & Jain, 2014b). This resulted in the establishment of a proactive exposure psychosocial risk indicator automatically published in the internal organisational performance management system of the organisation. The second study assessed the relationship between the psychosocial risk indicator (PRI) and objective measures, such as installation weight, age and leakage sources, of health and major accident potential, such as hydrocarbon leaks (Bergh, Ringstad, Leka & Zwetsloot, 2014c). Results from the analysis showed that only the psychosocial risk indicator significantly accounted for variation in hydrocarbon leaks. Only partial support was found for the relationship between technical factors and hydrocarbon leaks on the basis of correlation analysis. The third study describes the development of an internal audit tool of the psychosocial work environment in the oil and gas industry, focusing on offshore units (Bergh, Hinna, Leka & Zwetsloot, 2016). Psychosocial risk auditing is a proactive method for monitoring the status of psychosocial factors influencing the risk of stress and ill-health. The last study considered available quantitative and qualitative risk data collected through the PRIMA method over the last 8 years in the organisation to explore specific and common psychosocial risks in the petroleum industry in particular (Bergh, Leka, Zwetsloot, 2017). The results from the analyses confirmed the hypotheses proposed in the study that there was a significant correlation between job resources, job demands and symptoms of work-related stress and that there were differences in psychosocial risk factors and symptoms of work-related stress onshore and offshore. Future research should focus on testing the methods and tools developed in this company. Moreover, research should explore how other companies can incorporate and implement established knowledge on psychosocial risk management.

Earthquakes are amongst the worst natural disasters on Earth, resulting in an annual average of around 10,000 fatalities last century and progressively increasing in the amount of economic damage they cause, reaching US $20 billion per annum this decade. The mitigation of the unwanted consequences of earthquakes is normally achieved by Risk Management Strategies (RMS), which rely on the development of Earthquake Risk Assessment (ERA) techniques. This thesis aims to develop a framework for ERA for medium seismicity regions that incorporates the spatial aspects of the hazard and risk evaluation. The framework is used to undertake ERA for the island of Cyprus, and the information is used to propose RMS. The ERA framework relies on comprehensive data on the location, value and vulnerability of buildings and the population distribution. These data were collected from the various Cyprus Government Departments. Various hazard and attenuation models are examined, and the effect of their variability is taken into account through Monte Carlo simulations. The estimated annual risk for Cyprus is just below £ 10 million CY. This value was estimated based on the use of the re-appraised historical data for the past-century. Comparisons with other seismic hazard assessment methods, such as recurrence relationships, have revealed that, without a spatial distribution model, such approaches are unsuitable for ERA. Though the maximum intensities predicted are in line with the ones that underpin the aseismic code of Cyprus (CCEAA-CFEE, 1994), the predicted design accelerations are higher than given in the code. Hence, new seismic accelerations are proposed. Despite that, the current reduction in risk is comparable to the additional cost of aseismic design. Seismic retrofitting was also examined and it was found that as part of a general modernisation scheme seismic upgrading is cost effective. However, whatever the state of the building, it is recommended that earthquake insurance should be made mandatory. The current seismic insurance rates appear to be fair, though they seem to underestimate the risk in the areas of high seismicity. The number of likely human losses is also estimated. This study concludes that the result of ERA is heavily dependent on the models and data used, and both require constant updating for the ERA results to remain meaningful.

In the past century the occurrence of natural disasters and man-made disasters have steadily increased with a significant loss of life, damage caused to infrastructure and property, and destruction of the environment. There is much evidence that natural disasters are growing on a global level. Dealing with disasters demand the involvement of a range of agencies collaborating and making collaborative decision. This research has identified the need for a collaborative platform to bring together a variety of information to enable multi-agencies to prepare for disasters and to enhance the resilience of cities. Risk assessment is a crucial aspect within the activities of multi-agencies. Risk assessment enhances emergency planning which can then be tested by detailed appraisals and exercises. Whenever risk assessment is updated, plans are revised and additional tests are carried out. Risk assessment helps multi-agency planners decide what resource requirements they need and what multi-agency activities need to be planned collaboratively in order to prepare for disaster. The aim of this research is to investigate the nature of an interactive map that can enhance multi-agency team collaboration in the risk assessment process in disaster management. This research uses the six-step risk assessment process used in Australia and New Zealand which is widely recognized as being good practice. These steps are Contextualization, Hazard Review, Risk Analysis, Risk Evaluation, Risk Treatment and Monitoring and Reviewing (Standards Australia/Standards New Zealand Standard Committee, AS/NZS ISO 31000:2009). In this research, the characteristics of a suitable interactive map for risk assessment was defined in collaboration with the senior practitioners within a multi-agency team in the UK. Semi-structured interviews were conducted with the senior managers of Category 1 responders in The Greater Manchester Local Resilience Forum (GMLRF) to capture the requirements for a multi-agency collaboration platform. The outcome of these interviews were used to capture the characteristics and develop the a prototype of the interactive map that can support risk assessment. Once implemented, the validation of the interactive map prototype was conducted involving senior practitioners of stakeholders in the GMLRF development group. The experiment was held in the THINKpod in ThinkLab, at the University of Salford. A total of 23 senior practitioners took part in the evaluation experiment. After a demonstration of a scenario and using the interactive map, the participants evaluated the prototype as a group and then completed questionnaires that xv featured range of open, closed and rating scale questions. These questionnaires were designed to evaluate the perceived effectiveness and impact of the interactive map on strengthening collaboration among the multi-agency teams during risk assessment. The outcome of the evaluation shows a good level of satisfaction among the practitioners. The overall result suggests that the professionals view the interactive map as a good platform to support collaboration multi-agency teams in risk assessment activity.

The objective of the three studies in this dissertation was to improve methods to prevent musculoskeletal disorders among workers in high-risk occupations. The first two studies, Strain Index (SI) Studies I & II, addressed this problem by better characterizing the performance of a commonly used observational method of estimating potentially hazardous biomechanical exposures, the SI. The SI combines measures of several biomechanical risk factors into a single value (SI score). Strain Index scores are usually categorized into four ordinal SI "risk categories." In Strain Index Study I, multivariate survival analysis models were compared to evaluate the predictive validity of the original SI risk category cut-points to a new set of empirically derived cut-point values among 276 manufacturing workers. The results from this prospective study indicated that the empirically derived cut-points were a better predictor of incident hand-arm symptoms than the original cut-points, especially among women. In Strain Index Study II, Aim 1, exposures to forceful exertions, repetition and non-neutral wrist posture estimated with SI methods were compared to analogous exposures estimated with alternate methods. Statistically significant associations between separate methods designed to assess specific risk factors were observed only for those measuring non-neutral wrist posture. In Aim 2, a multivariate survival analysis model examining associations between incident hand-arm symptoms and biomechanical exposures estimated with the SI was compared to a model examining associations between incident hand-arm symptoms and biomechanical exposures estimated with separate estimates of biomechanical risk factors. Results favored the SI risk category metric to characterize biomechanical exposures compared to separate measures of exposure. he third study, light-weight block (LWB) Intervention Study, was a repeated measures laboratory study of 25 bricklayers performed to estimate the effect of block weight (LWB vs. standard-weight block (SWB)) and course height on low back disorder (LBD) risk factor exposure. Mixed-effect models showed that LWB was associated with reduced exposure for percent time spent in sagittal flexion >30°, lifting rate, LBD risk probability score, and non-dominant upper trapezius muscle activity. Bricklaying at ankle or chest heights was generally associated with higher exposure to risk factors than bricklaying at knuckle height.

Dissertação para obtenção do Grau de Doutor em Engenharia Industrial
The construction industry is plagued by occupational risky situations and poor working conditions. Risk Assessment for Occupational Safety (RAOS) is the first and key step to achieve adequate safety levels, particularly to support decision-making in safety programs. Most construction safety efforts are applied informally under the premise that simply allocating more resources to safety management will improve safety on site. Moreover, there are many traditional methods to address RAOS, but few have been adapted and validated for use in the construction industry, thus producing poor results. The contribution of this dissertation is a qualitative fuzzy RAOS model, tailored for the construction industry, named QRAM (Qualitative Risk Assessment Model). QRAM is based on four dimensions: Safety Climate Adequacy, (work accidents) Severity Factors, (work accidents) Possibility Factors and Safety Barriers Effectiveness. The risk assessment is based on real data collected by observation of reality, interviews with workers, foreman and engineers and consultation of site documents (working procedures, reports of work accident investigation, etc.), avoiding the use of data obtained by statistical tecnhiques. To rating each parameter it was defined qualitative evaluators - linguistic variables - which allow to perform a user-friendly knowledge elicitation. QRAM was, firstly evaluated by “peer” review, with 12 safety experts from Brazil (2), Bulgaria (1), Greece (3), Turkey (3) and Portugal (3), and then, evaluated by comparing QRAM with other RAOS tecnhiques and methods. The safety experts , concluded that: a) QRAM is a versatile tool for occupational safety risk assessment on construction sites; b) the specific checklists for knowledge elicitation are a good decision aid and, c) the use of linguistic variables is a better way to make the risk assessments process more objective and reliable.

Real-world problems especially the ones that involve natural systems are complex and they are composed of many non-deterministic components. Uncertainties associated with these non-deterministic components may originate from randomness or from imprecision due to lack of information. Until recently, uncertainty, regardless of its nature or source has been treated by probability concepts. However, uncertainties associated with real-world systems are not limited to randomness. Imprecise, vague or incomplete information may better be represented by other mathematical tools, such as fuzzy set theory, possibility theory, belief functions, etc. New approaches which allow utilization of probability theory in combination with these new mathematical tools found applications in various engineering fields. Uncertainty modeling in human health risk assessment and groundwater resources management areas are investigated in this thesis. In the first part of this thesis two new approaches which utilize both probability theory and fuzzy set theory concepts to treat parameter uncertainties in carcinogenic risk assessment are proposed. As a result of these approaches fuzzy health risks are generated. For the fuzzy risk to be useful for practical purposes its acceptability with respect to compliance guideline has to be evaluated. A new fuzzy measure, the risk tolerance measure, is proposed for this purpose. The risk tolerance measure is a weighed average of the possibility and the necessity measures which are currently used for decision making purposes. In the second part of this thesis two decision making frameworks are proposed to determine the best groundwater resources management strategy in the Savannah region, Georgia. Groundwater resources management problems, especially ones in the coastal areas are complex and require treatment of various uncertain inputs. The first decision making framework proposed in this study is composed of a coupled simulation-optimization model followed by a fuzzy multi-objective decision making approach while the second framework includes a groundwater flow model in which the parameters of the flow equation are characterized by fuzzy numbers and a decision making approach which utilizes the risk tolerance measure proposed in the first part of this thesis.

Petroleum Transportation Systems (PTSs) have a significant impact on the flow of crude oil within a Petroleum Supply Chain (PSC), due to the great demand on this natural product. Such systems are used for safe movement of crude and/or refined products from starting points (i.e. production sites or storage tanks), to their final destinations, via land or sea transportation. PTSs are vulnerable to several risks because they often operate in a dynamic environment. Due to this environment, many potential risks and uncertainties are involved. Not only having a direct effect on the product flow within PSC, PTSs accidents could also have severe consequences for the humans, businesses, and the environment. Therefore, safe operations of the key systems such as port, ship and pipeline, are vital for the success of PTSs. This research introduces an advanced approach to ensure safety of PTSs. This research proposes multiple network analysis, risk assessment, uncertainties treatment and decision making techniques for dealing with potential hazards and operational issues that are happening within the marine ports, ships, or pipeline transportation segments within one complete system. The main phases of the developed framework are formulated in six steps. In the first phase of the research, the hazards in PTSs operations that can lead to a crude oil spill are identified through conducting an extensive review of literature and experts’ knowledge. In the second phase, a Fuzzy Rule-Based Bayesian Reasoning (FRBBR) and Hugin software are applied in the new context of PTSs to assess and prioritise the local PTSs failures as one complete system. The third phase uses Analytic Hierarchy Process (AHP) in order to determine the weight of PTSs local factors. In the fourth phase, network analysis approach is used to measure the importance of petroleum ports, ships and pipelines systems globally within Petroleum Transportation Networks (PTNs). This approach can help decision makers to measure and detect the critical nodes (ports and transportation routes) within PTNs. The fifth phase uses an Evidential Reasoning (ER) approach and Intelligence Decision System (IDS) software, to assess hazards influencing on PTSs as one complete system. This research developed an advance risk-based framework applied ER approach due to its ability to combine the local/internal and global/external risk analysis results of the PTSs. To complete the cycle of this study, the best mitigating strategies are introduced and evaluated by incorporating VIseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) and AHP to rank the risk control options. The novelty of this framework provides decision makers with realistic and flexible results to ensure efficient and safe operations for PTSs.

Infrastructure development represents one of the major hindrances to economic growth and social development across all countries worldwide. A one percent increase in GDP is expected in a country with an estimated ten percent increase in infrastructure assets. Private project and structured financing is identified as the most effective tool for the provision of the required infrastructure. The complexity, formidable risks and highly leveraged nature of project and structured financing transactions account for the mismatch between the numbers of infrastructure financing transactions that reach financial close compared to the available pipeline. Increased literature focusing on the public sector procurer and private sector contractor is available in project and structured financing transactions, but scarce research focuses on the risk assessment processes applied by financiers to the due diligence of transactions. In this study, 15 in-depth semi-structured interviews were conducted with financing experts representing a diverse set of expertise with varying levels of experience in different markets. ATLAS.ti was used to analyse, code and identify themes in the data collected. The findings indicate a wide range of risks and scenarios are considered by financiers with the top risks being political or sovereign risk followed by construction risk. From the findings discussed, a financiers generalized risk assessment framework is created that can be applied to a wide range of project financing transactions and markets in context.

Environmental risks are traditionally assessed and presented in non spatial ways although the spatial relations between the risk assessment components and the spatial distribution of the risk assessment variables strongly influence exposure estimations and hence risks. According to the scale of the problem, two different spatial risk assessments approaches can be identified: site-specific spatial risk assessment and regional risk assessment. In the present Ph.D. thesis the first approach applies geostatistic interpolation methods for mapping the distribution of contaminants concentration in order to support the risk-based zoning of the site. It was implemented in DESYRE (DEcision Support sYstem for the REqualification of contaminated sites) and applied to the Porto Marghera case study. At regional scale, an innovative methodology integrating a relative risk approach and spatial analysis was developed to select sites at regional scale where a preliminary soil investigation is required first. It was implemented in SYRIADE (Spatial decision support sYstem for Regional rIsk Assessment of DEgraded land) and applied to the Upper Silesia case-study.
Tradizionalmente nella valutazione dei rischi per l’uomo e per l’ambiente, le relazioni spaziali tra le componenti dell’analisi di rischio e la distribuzione spaziale delle variabili coinvolte non vengono adeguatamente considerate, sebbene esse influiscono sulla valutazione dell’esposizione e quindi del rischio. In base alla scala di analisi, si possono identificare due approcci di analisi di rischio (AR): l’AR spaziale sito-specifica e l’AR regionale. Nella presente tesi di dottorato è stata sviluppata una procedura di AR spaziale sito-specifica che utilizza metodi di interpolazione spaziale per ottenere delle mappe di distribuzione della contaminazione al fine di supportare la zonizzazione del sito sulla base dei livelli di rischio. A scala regionale è stata sviluppata una metodologia innovativa che integra un approccio di AR relativo con analisi spaziali, per selezionare i siti dove le attività di caratterizzazione sono urgentemente richieste. Le due metodologie sono state implementate rispettivamente in DESYRE (DEcision Support sYstem for the REqualification of contaminated sites) e in SYRIADE (Spatial decision support sYstem for Regional rIsk Assessment of DEgraded land) e applicate al sito di Porto Marghera e alla regione dell’Upper Silesia.

The continuous desire to improve health and safety in UK construction has in recent years been challenged to adopt offsite strategies in order to address the poor health and safety record of construction. Despite the benefits of using offsite there has been little research on the actual benefits and disadvantages of the effect of offsite on occupational health and safety. This is important given that the UK government has promoted the use of offsite to improve health and safety performance. This thesis provides a strategy for the management of offsite risk and a risk management tool has been developed. The study investigated offsite manufacturers views on offsite activities and risks in comparison with insitu activities and risks. This was achieved through three phases: phase I comprised two expert group interviews, phase II involved ergonomic audits and phase III consisted of three semi-structured interviews with three offsite manufacturers. The thesis identified that there are significant health and safety benefits of offsite. The benefits relate to specific activities within the offsite categories and context studied. Examples include the elimination of work at height, reduction in noise, reduction in work in confined space, reduction in congested work with trade overlap and greater control over work in the factory. The research revealed that there are still potential health and safety risks with offsite. Examples include; transportation and delivery of units of large size and weight with associated high consequence craneage and handling risks (unit fall and hand injury), whole body vibration, cuts, MSDs, RSIs, fumes and slips trips and falls. There appears to be little in the literature to support the identification of offsite risk issues. The study identified strategies to eliminate and reduce offsite residual risks. The case study investigated solutions to further reduce residual risks, which were further explored in phase III the semi-structured interviews. The solutions are grouped into four approaches: process change, workplace environment designing out risks, automation and the use of tools. An offsite risk management tool was developed which transfers knowledge from the study to provide awareness and management of offsite risk. The thesis provides a contribution to knowledge by providing a better understanding of offsite risks, offsite residual risks and strategies used to reduce residual risks.

The field of modern project management is not new, and what seems to have changed over the past decade is the evolution of techniques applying theory into practice. This had as a consequence for the need to standardise and structure different processes of project management, in a detailed, documented and formal manner. On the other hand, change management seen as an integrated process within project management is a rational process for exploring decision and behaviour alternatives in an attempt to realign the course of ‘derailed’ deliverables due to change and ensure project success. However, models contained in such frameworks often lack formal semantics and clarity; generally fail to address and assess organisational change management risk reasoning, in a rather detailed way as they do for the majority of the project management processes. Since, uncontrolled changes might have an effect on the projects’ success, it is vital to assess the probability of materialisation (risk) of success before the decision is made and whether to proceed with the change or not. For example, if the change dramatically increases the risk of failure then it is logical to assume that avoiding that implementation is the right decision. Ideally, a change or consequence based upon a decision should have a low impact and a fairly high level of predictability. This research, takes the challenge to propose a novel modelling approach, which will contribute significantly to the missing formality of business models especially in the change risks assessment area. The introduction of Change Risk Assessment Model (CRAM) allows the identification and definition of speculative relationships, between change risks in the form of hierarchical risk tree analysis. Overall, the method is dynamic and flexible enough that can be tailored to various project requirements, taking into account significant environmental risk factors which influence project deliverables. Project success is a key objective for today’s organisations; professionals can make use of a new methodology for risk assessment, compatible with project management frameworks which currently seems to be missing from literature. Project management methodologies are not a panacea against project failure; nevertheless, CRAM can be regarded as a comprehensive modelling approach which combines both quantitative and qualitative risk criteria analysis in decision making processes.

ENGLISH ABSTRACT: Whenever projects fail, analysis of the causes has shown that risks were present from day one. Often individuals at some level in the project team have knowledge of these risks and they could have been identified and appropriate remedial action taken. Risk, whether identified or not, generally results in some increase in financial exposure on behalf of the organisation, but, if managed well, offers a potential that could lead to increased profits. There has been a tremendous explosion regarding the amount of data that organisations generate, collect and store. Managers are beginning to recognize the value of this asset and are increasingly relying on intelligent systems to access, analyse, summarise and interpret information from large and multiple data sources. These systems help them to make critical decisions at a faster rate or with a greater degree of confidence. Data mining is a promising new technology that helps bring intelligence into these systems. The purpose of this thesis is to present a methodology that integrates a data mining technique with a decision support system in order to form an intelligent decision support system. The implementation of such an intelligent decision support system will enable project and project risk managers to improve the management of and reduce risk within a project. This thesis consists of two sections. The first section describes the processes and characteristics of project management, project risk management, data mining and decision support systems. The aim is to provide the reader with a background about these four management methodologies. The second section describes the methodology of how the processes of project and project risk management can benefit from the integration of a data mining technique and a decision support system. An application that uses the case-based reasoning approach as a data mining technique to intelligently profile a project according to its risks is demonstrated.
AFRIKAANSE OPSOMMING: Wanneer projekte misluk, toon 'n analise van die oorsake dat risiko's vanuit die staanspoor daar teenwoordig was. Individuele persone op verskillende vlakke in die projekspan is dikwels daarvan bewus. Hierdie risiko's kon geïdentifiseer gewees het en regstellende stappe kon geneem gewees het. Risiko, hetsy geïdentifiseer of nie, loop gewoonlik uit op 'n sekere mate van toename in finansiële blootstelling namens die organisasie, maar wanneer dit goed bestuur word, bied dit 'n potensiaal vir verhoogde wins. Daar is 'n geweldige vermeerdering in die hoeveelheid data wat organisasies genereer, versamel en berg. Bestuurders begin alreeds die onskatbare waarde van hierdie bate besef en steun toenemend op intelligensiestelsels vir toegang, analise, opsomming en interpretasie van inligting van omvangryke en veelsoortige databronne. Hierdie sisteme stel hulle in staat om kritieke besluite vinniger of met 'n groter mate van vertroue te neem. Dataontginning is 'n belowende nuwe tegnologie wat daartoe bydra dat intelligensie in hierdie sisteme ingebring word. Die doel van hierdie tesis is om 'n metodologie wat 'n dataontginningstegniek met 'n besluitnemingsondersteuningsisteem integreer sodat 'n intelligente besluitnemingsondersteuningsisteem gevorm kan word. Die implementering van so 'n intelligensie besluitnemingsondersteuningsisteem sal projekbestuurders en projekrisikobestuurders in staat stelom die bestuur van 'n projek te verbeter en die risiko binne die projek te verminder. Hierdie tesis word in twee dele aangebied. Die eerste deel beskryf die prosesse en karakteristieke van projekbestuur, projekrisikobestuur, dataontginning en besluitondersteuningsisteme. Sodoende word aan die leser agtergrondinligting van hierdie vier bestuursmetodologieë verskaf. Die tweede deel beskryf die metodologie en hoe die prosesse van projekbestuur en projekrisikobestuur voordeel kan trek uit die integrasie van 'n dataontginningstegniek en 'n besluitondersteuningsisteem. 'n Toepassing is ontwikkel wat die gevallebasis beredeneringsbenadering as 'n dataontginingstegniek gebruik om 'n projek op 'n intelligente wyse volgens sy risiko's uit te beeld.

Risk assessment and risk management now underpin environmental protection in the UK. Risk assessment provides for a structured and systematic analysis of a problem, and is an objective tool to inform risk management decisions. In particular, risk assessment can assist in the prioritisation of management activities to direct resources more effectively to significant risks. However, the application of risk assessment remains ad hoc and often focused on quantified approaches. The problem of how to integrate the results of a risk assessment into decisionmaking processes remains. The objective of this research was to assess whether a knowledgebased approach could be usefully applied to risk management decisions associated with the protection of groundwater. The use of a knowledge-based system offers considerable potential to support regulatory decision-making relating to environmental risks. Such systems utilise expert knowledge to solve specific problems as an expert would but without requiring specialist or skilled users. This research describes the development of a prototype decision-support system to assist non-specialist regulatory personnel, in the prioritisation of risks and management activities relating to groundwater threats from hydrocarbon point-sources. The research focused on the knowledge acquisition process using semi-structured interviews, concept sorting and risk rating to identify the type of information required by the expert in their decision-making processes and also to distinguish any differences of approach between experts and 'non-experts'. A conceptual model was developed that represented expert decision-making and problem solving. This model was used to develop the prototype decision-support system which was subsequently evaluated by experts and users, resulting in system refinements. A positive response to the usability and utility of the system was received from both expert and user groups, suggesting a knowledge-based approach can be usefully applied to risk management decisions associated with the protection of groundwater.

This research thesis examined the risk of upper limb musculoskeletal disorders for cleaning workers while performing vacuum cleaning tasks in the normal course of their employment. The cleaning workers in this study were from three sectors of the workforce – government schools, hospitality and commercial office space. The vacuum cleaning tasks were divided into those performed with a back pack style vacuum cleaning machine and those using a canister/barrel machine. Three observational risk assessment tools were selected to measure the risk of these tasks to cleaning workers. The selected tools were the Manual Tasks Risk Assessment Tool (ManTRA) version 2.0; the Quick Exposure Check (QEC) (Li & Buckle, 1998); and the Rapid Upper Limb Assessment tool (RULA) (McAtamney & Corlett, 1993). Results of this thesis study demonstrated that vacuum cleaning is a risk to the musculoskeletal health of cleaning workers, with some variation between the tool ratings, reflecting the specificity and/or sensitivity of each tool. Differences were found between the three cleaning sectors in terms of overall risk posed by vacuum cleaning tasks. The sector with the greatest risk was found to be the government school cleaners, followed by the hospitality and then commercial office space cleaning sectors. The ‘risk experience’ difference between the sectors cannot be attributed only to vacuum cleaner characteristics, but also, the environment and length of shift worked by the cleaning staff. Further research is required to determine the difference in risk exposure between the two types of vacuum cleaner (back pack and canister).

The construction industry is a large industry with approximately 320,000 employees according to the Swedish construction industry. As the work environment at construction sites affects a large number of individuals, it is important that there is good security at the construction sites, in order to reduce and prevent workers in the construction industry from being injured. The work thesis has been carried out in collaboration with Tuna Förvaltning & Entreprenad AB with the aim of creating better conditions for work environment and strategic safety work at Tuna Förvaltning & Entreprenad AB's construction sites, as well as highlighting risks and safety aspects. This qualitative study has been carried out at Tuna Förvaltning & Entreprenad AB, where semi-structured interviews and observations were conducted to then use the information as the foundation of the study. The work has also been based on reviewed literature studies in the form of pre-review. In order to have a good working environment and safety at the construction sites, a number of factors are involved. The study shows that time, cleaning, communication, education and experience are the factors that have the greatest impact on the work environment and safety. According to some of Tuna Förvaltning & Entreprenad AB's workforce, there will always be deficiencies in safety, while some claim that a "zero vision" is possible to reach, so far no occupational accidents has occurred at Tuna Förvaltning & Entreprenad AB's construction sites, however, it seems that the subject does not get enough time, resources and like to prevent future accidents with "safety-first". The Work Environment Authority requires employers to systematically work with environment and safety issues with a vision of "zero tolerance", in which is strengthened by the work environment act. The interviews show that the viewpoint of the working environment differs depending on what perspective is being analyzed, for example, the supervisor has a wider perspective and greater responsibility whilst the professional worker has more narrow perspective and less responsibility. The survey shows that planning and preventive work can prevent workplace accidents with a systematic follow-up. In order for professionals and supervisors to understand the risks and preventive work they should be educated and thus gain an awareness of the problem. Improvement needs to create more awareness and prevention for work environment and safety with "safety deadline" have always been a goal to reach. One hope is that the working environment and security policy will contribute to improved security at the company's construction sites. systematic environmental work simplified by existing routines in environmental work for construction workers, leads to increased workplace safety and fewer occupational accidents.
Byggbranschen är en stor bransch med ca 320 000 sysselsatta personer enligt Sveriges byggindustrier. Då arbetsmiljön på byggarbetsplatserna påverkar ett stort antal individer är det viktigt att det råder en god säkerhet på byggarbetsplatserna, för att minska och förhindra att de anställda inom byggbranschen inte kommer till skada.Examensarbetet har utförts i samarbete med Tuna Förvaltning & Entreprenad AB i syfte att skapa bättre förutsättningar för arbetsmiljö och säkerhetsarbete ute på Tuna Förvaltning & Entreprenad AB:s byggarbetsplatser samt att belysa risker och säkerhetsaspekter. Kvalitativa studie har utförts på Tuna Förvaltning & Entreprenad AB:s byggarbetsplatser där semi-strukturerade intervjuer och observationer utförts för att sedan använda informationen som grundpelare i studien.För att det ska råda god arbetsmiljö och säkerhet på byggarbetsplatserna spelar ett flertal faktorer in. Studiens resultat visar att tid, städning, kommunikation, utbildning och erfarenhet är de faktorer som har störst inverkan på arbetsmiljön och säkerheten. Enligt en del av yrkesarbetarna på Tuna Förvaltning & Entreprenad AB kommer det alltid att finnas brister inom säkerheten medan en del påstår att en ”noll-vision” är möjlig att nå. Tuna Förvaltning & Entreprenad AB:s ett ungt företag och hittills har inga större arbetsolyckor inträffat på deras byggarbetsplatser. Emellertid tycker en del att ämnet inte får tillräckligt med tid, resurser och dylikt för att förhindra framtida olyckor med ”safety first”. Arbetsmiljöverket ställer krav på att arbetsgivaren skall arbeta systematiskt med arbetsmiljö och säkerhetsfrågor med en vision om ”noll-tolerans” vilket styrks av arbetsmiljölagen.Intervjuerna visar att synen på arbetsmiljön skiljer sig åt beroende på vilket perspektiv som analyseras, exempelvis har arbetsledare ett bredare perspektiv och större ansvar medan yrkesarbetaren har ett smalare perspektiv och mindre ansvar.Undersökningen visar att planering och förebyggande arbete kan förhindra arbetsplatsolyckor med ett systematiskt uppföljningsarbete. För att yrkesarbetare och arbetsledare skall ha förståelse för risker och förebyggande arbete bör de utbildas och därmed erhålla en medvetenhet kring problemet.Förbättringsbehov föreligger när det gället att skapa mer medvetenhet och ha ett förebyggande syfte för arbetsmiljö och säkerhet med ”safety first”. En förhoppning är att en bättre arbetsmiljö och en ny upprättad säkerhetspolicy kommer att bidra till en förbättrad säkerhet på företagets byggarbetsplatser. Det systematiska arbetsmiljöarbetet med förbättrad befintliga rutiner i arbetsmiljöarbetet för byggnadsarbetare bör leda till ökad säkerhet på arbetsplatsen samt undvika arbetsolyckor.
