Paternal Exposure to Ionizing Radiation in Ontario Uranium Miners and Risk of Congenital Anomaly in Offspring: A Record Linkage Case-control StudyNahm, Sang-Myong 30 August 2012 (has links)
Objective: To determine if paternal preconception exposure to ionizing radiation through uranium mining increases the risk of congenital anomaly (CA) in offspring.
Methods: A population-based matched case-control study was conducted. Cases were infants with CAs recorded in the Canadian Congenital Anomalies Surveillance System and born alive in Ontario 1979-86 (ICD-9 codes 740-759); controls were liveborn infants without CAs identified from Ontario birth certificates and individually matched to cases (case-control file {CCF}). Exposed fathers were identified through the linkage of the CCF to the Mining Master File or the National Dose Registry file, which include those who worked in Ontario uranium mines 1952-1986. For men who linked with a case or control child, radon, gamma and total gonadal doses were estimated for three preconception periods: entire, 3-months and 6-months. Odds ratios were estimated using conditional logistic regression.
Results: Linkage of 28,991 uranium miners and 40,482 case-control pairs of fathers and offspring in the CCF identified 431 discordant pairs. There was no evidence of increased risk of a child having a CA if the father was ever a uranium miner before conception of the child (OR=0.89, 95% CI=0.74–1.08). Since gamma radiation (especially during the 6-month preconception period) is more biologically relevant to gonads than radon, further analyses were performed on 117 discordant pairs where data on gamma exposures were available. When ever/never miner, exposed to gamma (yes/no), and gamma dose-response variables were all in the model, there was no ever/never miner effect (OR=1.20, 95% CI=0.85–1.69, p-value=0.30), an inverse association for exposure to gamma (OR=0.42, 95% CI=0.25–0.71, p-value=0.001), but most importantly, there was no statistically significant dose-response relationship between gamma dose during the 6-month preconception period and all CAs (OR=1.15 per loge {mSv+0.01}, 95% CI=0.83–1.59, p-value=0.40). Similarly, no dose-response relationship was observed for exposure to gamma radiation in the 3-month preconception period, or for radon or total gonadal radiation in the 3- or 6-month preconception periods.
Conclusion: There was no increased risk of a CA among liveborn children of Ontario uranium miners who were exposed to radon, gamma or total radiation during the 3- or 6-month periods before conception.

Prerequisites and Possibilities for Manufacturing Companies to Prioritize and Manage Occupational Health and SafetyNordlöf, Hasse January 2015 (has links)
Legislation demands that health and safety of humans at work must be secured. Today, far from every company has a functioning systematic management of occupational health and safety (OHS) in place to fulfill its legal obligations. Instead, other day-to-day tasks appear to have greater priority. The overall aim of this thesis was to investigate prerequisites and possibilities for manufacturing companies to prioritize and manage OHS, with focus on professional roles, company size, safety culture, and financial performance. Four papers (I–IV) are included in this thesis, based on three data collections. A questionnaire measuring the priority accorded to work environment was completed by 249 representatives of 142 manufacturing companies (I & II). Focus group interviews were conducted with 66 workers at a large steel-manufacturing company, discussing their experiences and perceptions of safety and risks at work (III). A questionnaire measuring OHS management practices, safety culture, and priority given to work environment was completed by 280 representatives of 197 manufacturing companies (IV). Information regarding the companies’ financial performance was retrieved from a credit bureau database. The main findings of the four papers demonstrated that profitability was considered as the most prioritized interest in the companies (I), and that trade-offs between productivity and safety is an obstacle to working safely (III). Managers generally perceived their companies to prioritize work environment factors more than the safety delegates did (I & IV). Perceptions of work environment priority did, however, not differ depending on company size (II & IV). Responsibility for safety was perceived to rest on the individual to the largest extent, and risk-taking was believed to originate from a combination of individual factors and external circumstances in the work environment (III). Larger company size, positive safety culture, and low risk in creditworthiness were found to be associated with better OHS management practices in companies (IV). Correspondingly, smaller company size, negative safety culture, and high risk in creditworthiness were found to be associated with worse OHS management practices. In summary, structural, social, and financial aspects seem to be important in companies’ possibilities for prioritizing and managing OHS. Recommendations for industry and future research are discussed. / Arbetsmiljölagen kräver att människors hälsa och säkerhet på arbetet ska tryggas genom att risker kontinuerligt ska bedömas och åtgärdas. Många företag saknar idag ett fungerande systematiskt arbetsmiljöarbete (SAM) som uppfyller lagens krav fullt ut. Istället tycks andra dagliga aktiviteter ha högre prioritet. Det övergripande syftet med denna avhandling var att undersöka förutsättningar och möjligheter för tillverkande företag att prioritera och arbeta med säkerheten och arbetsmiljön; med särskilt fokus på yrkesroller, företagsstorlek, säkerhetskultur och finansiella nyckeltal. Fyra delstudier (I–IV) ingår i denna avhandling, vilka är baserade på tre datainsamlingar. En enkät som mätte arbetsmiljöprioritering besvarades av 249 representanter vid 142 tillverkande företag (I & II). Fokusgruppintervjuer genomfördes med 66 arbetare på ett stort ståltillverkningsföretag, där deras erfarenheter och uppfattningar om säkerhet och risker i arbetet diskuterades (III). En enkät som mätte SAM, säkerhetskultur och arbetsmiljöprioritering besvarades av 280 representanter vid 197 tillverkande företag (IV). Information om företagens finansiella nyckeltal hämtades från ett kreditupplysningsföretag. De viktigaste resultaten från de fyra delstudierna kan bland annat sammanfattas med att lönsamheten uppfattades vara det mest prioriterade intresset vid företagen (I), och att avvägningar mellan produktivitet och säkerhet ansågs vara ett hinder för att kunna arbeta på ett säkert sätt (III). Chefer uppfattade generellt att arbetsmiljön prioriterades mer på företagen än vad skyddsombuden gjorde (I & IV). Uppfattningar om arbetsmiljöprioritering skiljde sig dock inte åt beroende på företagsstorlek (II & IV). Ansvaret för säkerheten på arbetet ansågs främst vila hos den enskilda individen, och risktagande betraktades komma ur en kombination av individuella faktorer och yttre omständigheter i arbetsmiljön (III). Att vara ett större företag, ha positiv säkerhetskultur och hög kreditvärdighet visade sig ha samband med att också ha ett bättre utvecklat SAM (IV). På motsvarande sätt, att vara ett mindre företag, ha negativ säkerhetskultur och låg kreditvärdighet befanns ha samband med att också ha ett sämre utvecklat SAM. Sammanfattningsvis verkar därmed strukturella, sociala såväl som ekonomiska aspekter vara väsentliga för företags möjligheter att prioritera och arbeta med säkerheten och arbetsmiljön. Detta ger uppslag till rekommendationer för industrin samt vidare forskning. / Das Arbeitsschutzgesetz verlangt, dass die Sicherheit und Gesundheit (SG) von Menschen am Arbeitsplatz gewährleistet werden muss, indem Risiken kontinuierlich überprüft und behoben werden. Vielen Unternehmen fehlt heutzutage eine systematische Handhabung von SG, die den gesetzlichen Anforderungen vollständig entspricht. Stattdessen scheinen andere alltägliche Tätigkeiten eine höhere Priorität zu haben. Das übergeordnete Ziel der vorliegenden Abhandlung war es zu untersuchen, welche Voraussetzungen und Möglichkeiten herstellende Unternehmen besitzen, SG am Arbeitsplatz zu priorisieren und handzuhaben – unter besonderer Berücksichtigung von Berufsrollen, Unternehmensgröße, Sicherheitskultur und Finanzleistungen. Die vorliegende Abhandlung besteht aus vier Teilstudien (I–IV), die auf drei Datensammlungen basieren. Die Priorisierung von SG wurde mit einem Fragebogen untersucht, der von 249 Vertretern aus 142 herstellenden Unternehmen beantwortet wurde (I & II). Fokusgruppeninterviews wurden mit 66 Arbeitern eines großen Stahlherstellers durchgeführt, in welchen die Arbeiter ihre Erfahrungen und Wahrnehmungen von Sicherheit und Berufsrisiken diskutierten (III). Ein weiterer Fragebogen enthielt Fragen zur systematischen Handhabung von SG, Sicherheitskultur und Priorisierung von SG und wurde von 280 Vertretern aus 197 herstellenden Unternehmen beantwortet (IV). Angaben zu den Finanzleistungen der Unternehmen wurden einem öffentlichen Register entnommen. Die wichtigsten Ergebnisse der vier Teilstudien können unter anderem damit zusammengefasst werden, dass die Rentabilität des Unternehmens als höchste Priorität wahrgenommen wurde (I) und dass Kompromisse zwischen Produktivität und Sicherheit als Hindernis für eine sichere Arbeitsweise beurteilt wurden (III). Manager waren im Allgemeinen häufiger als die Sicherheitsbeauftragten der Unternehmen der Auffassung, dass SG priorisiert werden (I & IV). Der Unterschied in der Wahrnehmung der Prioritätensetzung hing jedoch nicht von der Unternehmensgröße ab (II & IV). Sicherheit am Arbeitsplatz wurde in erster Linie als die Verantwortung des einzelnen Mitarbeiters angesehen und das Eingehen von Risiken als eine Kombination aus individuellen Faktoren und äußeren Umständen im Arbeitsumfeld beurteilt (III). Ein großes Unternehmen zu sein, eine positive Sicherheitskultur zu haben und niedriges Risiko in der Kreditwürdigkeit, erwies sich mit einer besser entwickelten systematischen Handhabung von SG in Zusammenhang zu stehen (IV). Dementsprechend erwies es sich, dass kleine Unternehmen, eine negative Sicherheitskultur und hohes Risiko in der Kreditwürdigkeit, mit einer schlechter entwickelten systematischen Handhabung von SG in Zusammenhang stehen. Zusammenfassend scheinen also strukturelle, soziale und finanzielle Aspekte grundlegend dafür zu sein, ob ein Unternehmen die Möglichkeit hat, SG zu priorisieren und zu handhaben. Dies dient als Vorlage für Empfehlungen für die Industrie und zukünftige Forschung.

Durée de lʼexposition avec symptômes, séquelles et coûts de lʼasthme professionnel en relation avec le statut psychologique et socioéconomiqueMiedinger, David 04 1900 (has links)
Le facteur le plus important de pronostic de l'asthme professionnel (AP) est la durée des symptômes avant le retrait de lʼexposition à lʼagent causant lʼAP. La qualité de vie réduite, la détresse psychologique et les maladies psychiatriques sont des conditions souvent associées à l'AP. Notre objectif était d'identifier les facteurs, incluant le statut socioéconomique, qui ont une influence sur lʼintervalle de temps nécessaire pour présenter une requête à une agence médicolégale à la suite de lʼapparition de symptômes dʼasthme et de confirmer qu'un tel délai est associé à un moins bon pronostic respiratoire et à des coûts directs plus élevés. En outre, nous avons examiné la relation entre les variables cliniques et socio-économiques dʼune part et leur influence sur les facteurs psychologiques et économiques dʼautre part chez des travailleurs atteints d'AP. Ensuite, nous avons voulu évaluer si les individus souffrant de détresse psychologique (DP) et de morbidité psychiatrique pourraient être identifiés en utilisant un instrument mesurant la qualité de vie (QV). Lʼétude a été effectuée auprès dʼindividus ayant déposé des demandes d'indemnisation pourʼAP auprès du Commission de la sécurité et de la santé du travail du Québec (CSST). Les données ont été recueillies au moment de la réévaluation, soit environ deux ans et demi après le diagnostic. Outre la collecte des marqueurs cliniques de l'asthme, les individus ont été soumis à une évaluation générale de leur histoire sociodémographique et médicale, à une brève entrevue psychiatrique (évaluation des soins primaires des troubles mentaux, PRIME-MD) et à un ensemble de questionnaires, incluant le Questionnaire sur la qualité de vie - AQLQ(S), le Questionnaire respiratoire de St. George (SGRQ) et le Psychiatric Symptom Index (PSI).Soixante personnes ont été incluses dans l'étude. Etre plus âgé, avoir un revenu supérieur à 30 000$ CA etêtre atteint dʼAP dû à un allergène de haut poids moléculaire ont une association positive avec le nombre dʼannées dʼexposition avec symptômes avant le retrait. Au cours de la période de suivi, le nombre dʼannées dʼexposition avec symptômes était plus grand chez les individus ayant une hyperréactivité bronchique persistante. Par ailleurs, la présence de symptômes au poste de travail pendant moins d'un an est associée à une réduction des coûts directs. Les paramètres de QV et de DP avaient des corrélations modérées avec les marqueurs cliniques de lʼAP. Les plus fortes associations avec ces variables ont pu être observées dans les cas de la sévérité de l'asthme, des statuts dʼemploi et matrimonial, du revenu et de la durée de la période de travail avec l'employeur. Un seuil de 5,1 au niveau de la sous-échelle de la fonction émotionnelle de lʼAQLQ(S) sʼest avéré avoir la meilleure valeur discriminante pour distinguer les individus avec ou sans détresse psychiatrique cliniquement significative selon le PSI. Nous avons été en mesure d'identifier les variables socio-économiques associées à un intervalle plus long dʼexposition professionnelle en présence de symptômes dʼasthme. De même, une plus longue période d'exposition a été associée à un moins bon pronostic de la maladie et à des coûts de compensation plus élevés. Ces résultats s'avèrent utiles pour la surveillance de lʼAP qui pourrait cibler ces sous-groupes d'individus. La QV et la PS sont fréquemment réduites chez les individus atteints d'AP qui perçoivent une compensation. Elles sont associées à des marqueurs cliniques de lʼasthme et à des facteurs socio-économiques. En outre, nos résultats suggèrent que le questionnaire de lʼAQLQ(S) peut être utilisé pour identifier les individus avec un niveau de détresse psychologique potentiellement significatif. / The most important factor in the prognosis of occupational asthma (OA) is the length of exposure with symptoms prior to removal from exposure. Impaired quality of life, psychological distress and psychiatric disease are conditions frequently associated with OA. Our goal was to identify factors, including socio-economic status, that can influence the delay in submitting a claim to a medicolegal agency after the onset of asthmatic symptoms, and to confirm that such a delay is associated with a worse respiratory prognosis and higher direct costs. Further, we examined the association between clinical and socio-economic variables and their influence on psychological and cost outcomes in individuals with OA. Next, we wanted to evaluate whether individuals with clinically significant psychological distress (PD) and psychiatric morbidity could be identified by using a quality of life (QOL) measurement instrument. This is a study of individuals who filed claims for compensation for occupational asthma from the Workersʼ Compensation Board of Quebec (the CSST). Data were collected at re-evaluation, approximately two and a half years after diagnosis. Besides collecting clinical markers of asthma, individuals underwent a general socio-demographic and medical history evaluation, a brief psychiatric interview (Primary Care Evaluation of Mental Disorders, PRIME-MD) and completed a battery of questionnaires, including the Asthma Quality of Life Questionnaire - AQLQ(S), the St. Georgeʼs Respiratory Questionnaire (SGRQ), and the Psychiatric Symptoms Index (PSI). Sixty individuals were included in the study. Being older, having a revenue of >$30,000 Can. (CAD$) and having OA due to high- molecular- weight agents were all positively associated with the number of years of exposure with symptoms before removal from exposure. Individuals with persistent airway hyperresponsiveness at follow-up had a higher number of years with symptoms. Experiencing symptoms in the workplace for less than one year generated lower direct costs. QOL and PD parameters had moderate correlations with clinical markers of OA. Asthma severity, employment and marital status, income and length of employment with the employer showed the strongest associations with QOL and PD. More impaired QOL was associated with higher direct costs for compensation. A cut-off of 5.1 on the AQLQ(S) emotional function subscale had the best discriminative value to distinguish individuals with or without clinically significant psychological distress according to the PSI. We were able to identify socio-economic variables that were associated with a longer interval during which individuals remained symptomatic in the workplace before being removed from exposure. This longer exposure time was associated with worse disease outcomes and higher compensation costs. These findings could prove to be useful in surveillance programs that could be preferentially targeted for these subgroups of individuals. Impaired QOL and PD are frequent among individuals with OA receiving compensation and are associated with clinical markers of OA and socio-economic factors. Further, our findings suggest that the AQLQ(S) questionnaire could be used to identify individuals with potentially clinically significant levels of psychological distress.

Environmental risk assessment for the electricity sector : a case of Swaziland electricity companyVan Zuydam, Constance Sthembile 06 1900 (has links)
The provision of reliable, safe, affordable and accessible power supply is one of the most important cornerstones for economic development, particularly for third world countries. Notwithstanding all known benefits of power supply, there are environmental risks associated with electricity generation, transmission and usage that need to be identified, assessed and managed. These risks range from minor to major risks such as serious bodily harm and fatalities as well as environmental degradation. In order to minimise and control the operational risks, it is key for the sector to ensure that the risks are identified and assessed using appropriate tools and systems to ensure sustainability and safe work environments. This study explored, improved and designed a tool for environmental risk assessment within Swaziland Electricity Company, (SEC) based on clause 4.3.1 of ISO 14001 (2004), Environmental Management System and Occupational Health and Safety Assessment Series, OHSAS 18001 (2007), Occupational Health and Safety System. The previous risk assessment and evaluation tool used in the company ignored existing risk control practices employed and thus did not truly quantify identified risks.
The methodology presented in this study focused on the identification of hazards/aspects and risks associated with processes in electricity generation, transmission and distribution. Risks were evaluated and all possible measures to control the identified risks were suggested.
The top three significant hazards identified include; exposure to live wires, road hazards and the use of uncertified/ defective/wrong equipment and/or machinery whilst the significant impacts were: soil pollution, natural resource degradation/ depletion, loss of flora and fauna and social impacts. The distribution department was observed to have the most environmental risks when compared to the other departments. The developed tool and data could be used as baseline information by other sectors wishing to implement environment and safety systems. It will also continually improve the safety and environmental performance of SEC. / Environmental Science / D. Phil. (Environmental Science)

Development of practical guidelines to promote occupational health and safety for workers in the construction industry in Windhoek, NamibiaNghitanwa, Emma Maano 11 1900 (has links)
Text in English / The study, which considers that the construction industry is a high risk one due to the physical work demand and nature of the working environment, was conducted to develop practical guidelines for workers and employers that promote occupational health and safety (OHS) in the construction industry in Namibia. The study, conducted at 13 study sites in Windhoek, Namibia, used a quantitative descriptive study method to gather data regarding the OHS status of the construction industry.
Data was collected from the 13 study sites using a site interviewer-led questionnaire for 549 construction workers. In addition, both a site inspection checklist and document review checklist were used to collect the data from ten construction sites. A review of documents concerning occupational accidents, diseases and injuries encountered at construction sites that were held by the Ministry of Labour, Industrial relations and Employment creation for the five-year period from April 2011 to March 2016 was carried out. Data was analysed using the Statistical Package for Social Sciences (SPSS) software version 23.
The study findings show that most of the workers at the study sites were young and male, with most participants lacking awareness of OHS issues, which may hinder accidents and injuries prevention. It also emerged that occupational hazards are prevalent at the study sites and yet there were poor mechanisms for hazard prevention or mitigation measures.
The study notes that there was a high rate of occupational accidents and injuries, as well as a few incidences of health hazards, as indicated by few participants, although there was no documented occupational disease. It is also noted that most study sites do not comply with OHS legislations, such as having OHS policies that indicate the employer’s commitment towards OHS, which placed workers at risk of hazard exposure, occupational accidents, injuries and diseases. Practical guidelines to promote OHS in the construction industry of Windhoek, Namibia are developed as the primary output of this project. / Health Studies / D. Litt. et Phil. (Health Studies)

Developing and evaluating a coaching program to improve safety leadershipEsterhuizen, Wika 11 1900 (has links)
Legislators are placing increased pressure on mining companies to improve their
safety performance. The importance of safety leadership is highlighted by its role in
safety culture and improving safety performance. The aim of this study was to
develop and evaluate the impact of a coaching program on safety leadership.
The main constructs namely safety culture, safety leadership and coaching was
conceptualised along the humanistic paradigm, with theoretical definitions and
models. In this study, safety culture is employees’ shared attitudes, beliefs,
perceptions and values about safety that affect their behaviour in the workplace.
Safety leadership is the interpersonal influence that a leader exercises to achieve
the organisation’s safety performance goals. Coaching is an interpersonal
interaction that aims to improve individual performance through increased selfawareness
and action plans. A theoretical model was developed to explain the
elements that constitute effective safety leadership. A coaching program was
developed based on executive coaching and leadership development principles.
The empirical investigation was conducted in an organisation in the South African
mining industry. A nested mixed methods design was followed. In the quantitative
study, a 360 degree survey was employed to assess the ratings of a purposive
sample (n=54) along eight dimensions before and after the coaching. Data was
analysed with descriptive and inferential analysis. Results showed statistically
significant improvements on accountability, collaboration, and feedback and
recognition after the coaching. The results reflected differences in 360 degree
ratings according to gender, race, job level, age and geographical location. The
most significant improvements were for females, Africans, management, age 51-60
years, and site 2.
In the qualitative study, a semi-structured interview was employed to study four
cases to investigate managers’ personal experiences and changes in attitude
toward safety. Data was analysed utilising thematic analysis. The findings revealed
that coaching was a positive experience and contributed to changing managers’
attitudes toward safety.
The research added to the field of organisational behaviour by presenting a
theoretical model that enhances the understanding of safety leadership, the
development of a coaching program and providing empirical evidence that the
principles of coaching and leadership development can be applied to improve
safety leadership. / Industrial and Organisational Psychology / D. Admin. (Industrial and Organisational Psychology)

Previous issue date: 2015-11-24 / A pesquisa em questão foi direcionada ao estudo das práticas organizacionais de Saúde e Segurança Ocupacional (SSO), onde se relacionam diretrizes de uma gestão responsável baseada em normas e indicadores de Responsabilidade Social Organizacional (RSO), com o foco na promoção e manutenção de melhores condições de trabalho ao stakeholder interno. Existem diferenciais na ênfase das práticas de gestão nos setores públicos e privados, nos segmentos industriais de manufatura e serviços. Torna-se importante constatar as evidencias dessas diferenciações e tentar explica-las.O objetivo desta pesquisa é avaliar se existe dependência entre as práticas de gestão em SSO, em sinergia com a RSO, e o setor (público ou privado) ou o segmento industrial (manufatura ou serviço) em que as organizações se inserem, segundo a percepção dos profissionais que nelas atuam. A revisão da literatura que envolve a temática abordada possibilitou a construção de um questionário (survey), cuja aplicação foi realizada em uma amostra de 86 profissionais de distintas formações e áreas de atuação. Os dados obtidos foram tratados por meio de métodos, técnicas e ferramentas de estatística descritiva para avaliar a percepção destes profissionais acerca das práticas de gestão em SSO, em sinergia com a RSO, em suas respectivas organizações. Buscou-se verificar a dependência entre esta percepção com o setor e com o segmento industrial em que a organização se insere, através do teste de Qui-quadrado de Pearson ou Teste exato de Fisher. Como resultado, observou-se considerável adesão à estas práticas por parte das organizações. No entanto, esta adesão depende do setor e do segmento industrial em que a organização está inserida. Constatou-se maior adesão às práticas estudadas nas organizações privadas, comparadas com as públicas, e no segmento industrial de manufatura, comparada com as de serviço. / This research was directed to the study of organizational practices of Occupational Health and Safety (OHS), which relate guidelines for responsible management based on Organizational Social Responsibility (OSR) standards and indicators, with focus on the promotion and maintenance of best working conditions to the internal stakeholder. There are differences in the emphasis of management practices in the public and private sectors in industries of manufacturing and services. It is important to note the evidence of these differences and try to explain them. The objective of this research is to assess whether there is dependence between management practices in OHS, in synergy with the OSR, and the sector (public or private) or the industrial sector (manufacturing or service) in which organizations fall as perceived the professionals who work in them. A review of the literature involving the theme addressed enabled the construction of a questionnaire (survey), whose application was performed in a sample of 86 professionals from different backgrounds and areas of expertise. Data were treated by means of methods, techniques and descriptive statistics tools to assess the perception of these professionals about the management practices in OHS, in synergy with the OSR in their respective organizations. We attempted to verify the dependence of this perception with the sector and the industrial sector in which the organization is inserted through Pearson’s Chi-Square test or Fisher's exact test. As a result, there was a considerable adherence to these practices by organizations. However, this adherence depends on the sector and the industrial segment in which the organization operates. It was found greater adherence to the practices studied in private organizations, compared with the public, and industrial manufacturing segment, compared with the service segment.
