14	Evaluation of thermal desorption as an alternative technique for the measurement of coal tar pitch volatiles / Cornelius Johannes van der Merwe Van der Merwe, Cornelius Johannes January 2011 (has links) Motivation: The accurate and reliable measurement of the concentration of coal tar pitch volatiles (CTPVs) in ambient air has proved to be a challenge for occupational hygienists. The challenge must however be confronted due to, amongst others, the carcinogenic properties of some poly–aromatic hydrocarbons (PAHs) contained in CTPVs. Aim: To determine the feasibility of a thermal desorption (TD) technique based method as an alternative method to be used for the measurement of the concentration of CTPVs in ambient air by assessing it along criteria such as ease of use, cost, accuracy and precision by comparing it to NIOSH’s Method 5515 and OSHA’s Method 58 and to determine the level of exposure to CTPVs on the anode paste floor of an electric furnace, used for the smelting of platinum group metals (PGMs) concentrate. Methodology: To satisfy the research objective, two accepted methods the National Institute of Occupational Safety and Health’s (NIOSH) method 5515 and the Occupational Safety and Health Administration’s (OSHA) method 58 were used for the measurement of the concentration of CTPVs with a TD technique based method used as a third, alternative method. All three methods were used concurrently to measure the concentration of CTPVs in ambient air, at the anode paste floor of a platinum group metals (PGMs) concentrate smelter. Results and conclusions: The NIOSH method proved to be the most precise method while the TD technique based method proved to be the most accurate. The TD technique based method proved to measure the widest range of individual CTPVs and were able to measure the highest concentration of Benzo(a)pyrene, an individual CTPV that is classified as a Group 1 (carcinogenic to humans) chemical substance by the International Agency for Research on Cancer (IARC). The OSHA method measured on average almost four times less total CTPVs than either the NIOSH or the TD technique based method and failed to readily measure individual CTPVs with a molecular weight lower than that of Phenanthrene. / Thesis (M.Sc.

No. of bitstreams: 1 Ribeiro_IvanAugustoVall_M.pdf: 11470420 bytes, checksum: 7b4d66edae261245bb8810ee6aa0e792 (MD5) Previous issue date: 2007 / Resumo: A Tomaticultura constitui-se num dos maiores mercados agrícolas brasileiros, gerando mais de duzentos mil empregos diretos. Atualmente a exigência por produtos seguros se fortalece num ritmo muito acelerado, fazendo com que o beneficiamento pós-colheita dos produtos agrícolas se constitua numa atividade em grande expansão no Brasil. A Movimentação Manual de Cargas (MMC) nas unidades de beneficiamento de tomates (UB) é a atividade laboral mais freqüênte nas etapas do processo de beneficiamento e a que mais expõe os trabalhadores a riscos de lesão do sistema osteomuscular. O objetivo geral desse estudo foi analisar as tarefas de MMC das Unidades de Benrficiamento de Tomate de Mesa, visando contribuir para a prevenção das ocorrências de distúrbios osteomusculares nos trabalhadores. Para a realização do estudo, foram escolhidas seis Unidades de Beneficiamento, todas localizadas no estado de São Paulo. A compreensão do funcionamento geral das UB, foi possível a partir da aplicação do método da Análise Ergonômica do Trabalho (AET). Através de ferramentas que compõem o método da AET, como as observações sistemáticas, que possibilitaram o conhecimento do fluxo de produção, e as verbalizações dos trabalhadores, foi possível a identificação das etapas do processo de beneficiamento em que a MMC se apresentava com maior predominância. Para avaliar o risco de lesão do sistema osteomuscular dos trabalhadores nas etapas selecionadas dentro do processo de beneficiamento onde a MMC se apresentava de forma predominante, foram aplicados os métodos da equação National Institute for Occupational Safety and Health (NIOSH), que é um método de análise quantitativa e que determina o Limite de Peso Recomendado (LPR) para cada tarefa e o método do Diagrama das Áreas Dolorosas que é um método subjetivo em que os trabalhadores através de um questionário apontam para as áreas do corpo que apresentam desconforto. Em todas as etapas do processo de beneficiamento estudadas, o peso real da carga movimentada manualmente superou o limite de peso recomendado (LPR) pelo NIOSH. O Diagrama de Áreas Dolorosas identificou extremo desconforto na área posterior do tronco, ombros, braços e antebraços, corroborando os resultados obtidos pela equação do NIOSH / Abstract: Tomato cropping is one of the biggest Brazilian agriculture markets, that generates more than 200,000 direct jobs. Nowadays the demand for safe products increases in a very accelerated rhythm, making the post harvest beneficiary process of the agriculture products an activity with a great expansion in Brazil. The manual material handling (MMH) in the fresh tomatoes packing houses is the most frequent labor activity in the phases of beneficiary process and the one of major risk of bone-muscle system lesion to the workers. The main goal of this work was to analyze the MMH tasks in six table tomato packing house in order to contribute to the prevention of the bone-muscle disturb occurrences in them. To accomplish this six packing houses located in São Paulo state were chosen. The comprehension of the packing house general functionalities was accomplished from the application of Work Ergonomic Analyses (WEA) method. Using WEA method tools, as the systematic observations, made it possible the identification of beneficiary process phases in which the MLM was predominant. In order to evaluate the risk of bone-muscle system lesion of the workers in the selected phases of the beneficiary process where MMH was predominant, two methods were applied: the first one was the Equation Method of the National Institute for Occupational Safety and Health (NIOSH), which is a quantitative analysis method that determines the Recommended Weight Limit (RWL) for each task. The second one was the Painful Area Diagram method, which is a subjective method where the workers indicates, through a questionnaire, the body areas which present discomfort. In all studied phases of the beneficiary process, the actual load weight manually moved overcome the NIOSH recommended weight limit (RWL). The painful area diagram identified extremely discomfort in the posterior area of the trunk, shoulders, arms and forearms, reaffirming the results obtained by the NIOSH equation / Mestrado / Planejamento e Desenvolvimento Rural Sustentável / Mestre em Engenharia Agrícola Lesões por esforços repetitivos Armazenamento e transporte de cargas Ergonomia Tomate Lycopersicon Unidades de beneficiamento Tomato cropping Tomato packing house Manual material handling Ergonomics work analysis NIOSH equation

18	Bullying: Out Of The School Halls And Into The Workplace Cooney, Lucretia 01 January 2010 (has links) The primary purpose of this study is to identify those people at most risk of being bullied at work. While much research is being conducted on school bullying, little has been conducted on workplace bullying. Using data gathered from a 2004 study conducted by the National Opinion Research Center for the General Social Survey, which included a Quality of Work Life (QWL) module for the National Institute for Occupational Safety and Health (NIOSH), linear regressions indicated significant findings. As predicted, workers in lower level occupations, as ranked by prestige scoring developed at National Opinion Research, are more likely to be victimized. Data also suggest that being young, Black, and relatively uneducated may contribute to being bullied in certain situations. Future research is needed to examine influences of socio-economic, legal, and other demographic factors that may predict the chance of being bullied. psychological abuse mobbing verbal abuse workplace bullying workplace harassment workplace mistreatment workplace aggression psychological violence employee employee emotional abuse emotional emotional abuse bullying job workplace bully occupational mobbing incivility interpersonal conflict harassment psychological violence employee abuse psychological service service positions women black non-white narcissists work boss bosses managers target age IPV interpersonal violence younger females marital status divorced single married occupation positional power relational power Marx Marxist social social conflict education health minority education region attendance church religious professional educational NIOSH prestige put down act upset upset shout personal space space sociology policy victim business academia co-worker humiliation intimidation slander social isolation isolation perpetrator stress discriminatory discrimination hospital court harassment Sociology
