Specifically, an investigation is made, based on the Policy and Quality Objectives adopted by construction companies who engage in the sector of vertical buildings, in the Metropolitan Region of Recife, whatever may be the determining data for this enterprise and the types of objectives which include each of the sectors researched, namely Safety at Work and Quality of Life at Work. The methodology used, based on case studies, initially considered the analysis of the recognizably successful experience of one civil construction company which implemented actions for improving quality of life on its building sites. Thereafter, using the data collected in selected companies, pieces of information were obtained which pointed to features lacking in the objectives of the system of quality management which contemplated the object of this study. Therefore, as a practical suggestion arising from this study, ten actions have been proposed for improving the conditions of life and/or safety of workers on building-sites, set out step-by-step, in such a way as to guide and facilitate their implementation by building firms. / Esta dissertação tem como objeto de estudo a qualidade de vida e segurança do trabalho em canteiros de obra e objetiva analisar o comprometimento de empresas da construção civil que possuem um sistema de gestão da qualidade implantado e certificado de acordo com a NBR ISO 9001:2000, com a segurança e a qualidade de vida no trabalho dos seus funcionários em canteiros de obra. Investiga-se, especificamente, a partir da Política e dos Objetivos da Qualidade adotados por construtoras que atuam no setor de edificações verticais, na Região Metropolitana do Recife, quais os dados determinantes para esse empenho e os tipos de objetivos que contemplam cada um dos setores pesquisados, quais sejam, a Segurança do Trabalho e a Qualidade de Vida no Trabalho. A metodologia utilizada, baseada em estudos de casos, inicialmente contemplou a análise da experiência reconhecidamente bem sucedida, de uma empresa da construção civil que implantou ações de melhoria da qualidade de vida em seus canteiros de obra.

Neste sentido, como sugestão prática deste trabalho, foram propostas dez ações de melhoria das condições de vida e/ou segurança dos trabalhadores em canteiros de obra, conduzidas passo a passo, de modo a direcionar e facilitar a sua implantação por empresas construtoras.

The purpose of this project was to develop an employer handbook to assist them in developing a return to work program for industrially injured workers.

Background: Low morale is classified as a latent condition for performance variability in safety-critical environments. Morale management may assist in the control of performance variability as part of a systems approach to safety. A context-specific model for measuring and managing morale with reference to followership in a safety-critical air traffic control (ATC) environment could not be found. Purpose/Aim: The purpose of this study was to develop a model that enables the measurement and management of air traffic controller (ATCO) team morale. Research Design: An exploratory sequential mixed method design was adopted. A census approach to sampling was used to conduct 21 focus group sessions as the qualitative phase, providing the definition and drivers of morale. The Measure of Morale and its Drivers (MoMaD) survey instrument was created from qualitative data, then administered to 256 ATCOs in the quantitative phase. Statistical methods included exploratory factor analysis, correlation and regression analysis to construct the final MoMaD model. Results: A context-specific definition of morale is provided and communication management, team cohesion, leadership interaction, staff incentive, staffing level, workplace health and safety and mutual trust were found to be the drivers of morale in a safety-critical ATC environment. A single-item measure of perceived morale reflected the state of context-specific ATCO team morale more accurately than an existing generalisable multi-item measure. Conclusion: This study contributes to the body of knowledge by integrating applicable aspects of morale, followership, performance variability and organisational culture and climate in safety-critical ATC environments into a new theoretical framework. The MoMaD instrument is presented as a context-specific model for measuring and managing ATCO team morale in an ATC environment. Recommendations: Future research opportunities include the possible influence of morale as a predictor of morale in safety-critical environments and the development of a context-specific multi-item measure of morale for integration into the MoMaD model. / Business Management / D.

In industrial environments workers can be prone to dangerous situations that may cause harm. In order to prevent accidents and fulfill legislative requirements for safe working condition, a safety system can be needed to be installed in place. In an attempt to bring a principal improvement in the safety standards offered by conventional systems in existence, a radar sensor is proposed for the detection of dangerous situations. This thesis explores the limiting performance of the radar sensor in an industrial safety system. The radar sensor is an FMCW mode MIMO radar and we develop a model to simulate the radar sensor based on its hardware design. The model is utilized to deduce and analyze the performance limits of the radar sensor, by using a Finite Element Method to determine the electromagnetic scattering response of a target in the operating frequency band, 60-64 GHz. Appropriate dielectric and magnetic properties of human tissue is assigned to obtain accurate scattering responses of a human body target. The performance analysis is done by comparing the reflection from various protruding body parts, with the reflection from the torso, over a wide range of postures of the body. Further, CFAR, a common form of detection algorithm is applied on a few of the postures to detect a protruding part the body. Finally, a discussion on the limited performance is made, and potential methods to enhance the performance of the radar sensor in an industrial safety system are suggested. / I industriella miljöer kan arbetare utsättas för farliga situationer vilka kan orsaka skador. För att förhindra olyckor och uppfylla lagstadgade krav för säkra arbetsförhållanden kan säkerhetssystem behöva installeras på plats. I ett försök att åstadkomma en förbättring av de säkerhetsstandarder som erbjuds av konventionella system föreslås en radarsensor för att detektera farliga situationer. Denna avhandling undersöker möjliga begränsningar i prestanda hos en radarsensor, vilken ingår som komponent i ett industriellt säkerhetssystem. Radarsensorn är en MIMO-radar, som arbetar i FMCW-mod, och vi utvecklar en modell för att simulera radarsensorn utgående ifrån dess hårdvarudesign. Modellen används för att härleda och analysera begränsningar i prestanda hos radarsensorn, genom att med hjälp av finita elementmetoden beräkna spridningen av elektromagnetiska vågor från ett radarmål i frekvensbandet 60-64 GHz. Tillämpliga dielektriska och magnetiska egenskaper hos mänsklig vävnad har använts för att erhålla tillförlitliga data på spridningsresponsen för människokroppen. Prestandaanalysen görs genom att jämföra reflektionen från olika utskjutande kroppsdelar med reflektionen från bålen över ett stort antal kroppshållningar. Vidare, CFAR, en vanlig form av detektionsalgoritm tillämpas på några av hållningarna för att detektera utskjutande delar av kroppen. Avslutningsvis diskuteras begränsningarna i prestandan och potentiella metoder för att förbättra radarsensorns prestanda i ett industriellt säkerhetssystem föreslås.

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 & Organisational Psychology / D.

Thesis (MMed (Occupational Medicine))--Stellenbosch University, 2013. / Introduction Exposure incidents involving blood and body fluids represent a major hazard for medical undergraduates. Every medical teaching university experiences the problem of undergraduate medical students sustaining such incidents. Although Post Exposure Prophylaxis (PEP) is readily available and accessible to medical undergraduates following an incident, continuity and quality of care extends beyond the provision of PEP. This includes follow up consultations after receiving PEP according to protocol. Study Design This study was performed at the Tygerberg Campus of Stellenbosch University in Cape Town, South Africa to assess compliance with follow up consultations following an exposure incident. The study base consisted of all the medical undergraduates who reported an exposure incident at the Campus Health clinic. Cases were defined as medical undergraduate students of Stellenbosch University who had reported an exposure incident between January 2007 and December 2011. They were identified using the clinic database and records. Influential factors associated with the exposure incident, including compliance regarding follow up consultations were obtained from standardised reporting forms and medical records. The data was analysed in 2 sections, a cross sectional component (descriptive and analytical) and a retrospective cohort component. Two student cohorts were retrospectively followed from the beginning of their 3rd year to the end of their medical curriculum (6th year). Results There were 280 exposure incidents reported in the study period, of which 174 were low risk and were 106 high risk incidents for which PEP was prescribed (37.86% used PEP). For those who had high risk exposures, 90.57% (n=96) attended the 6-week follow up consultation, 48.11% (n=51) attended the 3 month visit and 34.91% (n=37) attended the 6 month follow up visit. There was an increase in the number of exposure incidents from 2010 (n=43) to 2011 (n=76). Internal medicine accounted for the most number of incidents (n=68), followed by Surgery (n=51), Obstetrics and Gynaecology (n=44), and Paediatrics (n=42). Drawing blood was the most common reported activity associated with exposures. Of notable importance was recapping, disposing of needles and insertion of blood into sample tubes. These activities accounted for 63 of the 280 exposure incidents. The 4th year students were the least at risk for exposure incidents compared to 3rd, 5th, 6th years. The annual average cumulative risk of having an exposure incident was found to be 5.7% (95%CI=4%-8%) and 6.8% (95%CI=5%-9%) amongst the 2 student cohorts over the duration of 4 years (clinical exposure time). Recommendations There is an urgent need for the number of exposure incidents to be reduced, e.g. needle recapping and disposal, and insertion of blood in sample tubes cause numerous preventable incidents. Various other strategies can be implemented in order to reduce the number of incidents across all undergraduate years of study. It is envisaged that by reducing the number of exposure incidents, there will be a subsequent decrease in the number of individuals requiring PEP. The importance of ensuring compliance with regard to follow up consultations needs to be emphasized. Factors that lead to noncompliance need to be investigated in a separate study.

Submitted in fulfillment of the requirements For the degree of Master of Technology: Environmental Health, Durban University of Technology, Durban, South Africa, 2016. / Work related injuries are of major public importance and have adverse economic and social impacts. Forestry work is one of the most hazardous occupations worldwide and accounts for a large proportion of occupational injuries. Employers frequently train workers in the proper and safe use of equipment, however the efficacy of these programmes are seldom rigorously evaluated. The aim of this study was to assess the effectiveness of health and safety training in reducing injuries among forestry workers in Kwa-Zulu Natal. A descriptive study was conducted among 300 Kwa-Zulu Natal harvesting contract workers. A questionnaire to assess the efficiency of health and safety training was administered. A retrospective review of the injury register and medical records of employees who sustained work related injuries, fatalities during 2009–2013 was done. The company injury data for harvesting contractors from 2009- 2013 reported 3 fatalities and 68 lost time injuries during post commencement of training. About 23.3% workers reported injuries during the study period. Slip, trip and fall injuries were the most reported cause of injuries. Almost 95% of respondents reported that they had received health and safety training at work, with 84% reporting satisfaction with the quality of training received. A decreased prevalence of work related injuries was reported post training. The health and safety program was successful in increasing workers awareness and responsibility of health and safety issues. On- going specific job training, sustained work place inspections and adult learning for supervisors will improve health and safety of workers and reduce injuries in the forestry industry. / M

The International Labour Organization (ILO) estimates that more than 2.3 million workers die yearly from work related accidents and diseases and this is probably an underestimation. Estimates indicate that occupational accidents are a serious problem in the world. The aim of this study is to investigate the nature and magnitude of health and safety challenges affecting workers in small-scale and informal woodworking enterprises and to develop guidelines for improvement. As a quantitative research, the exploratory-descriptive and contextual designs were used to conduct this research. Snowball sampling was used to collect data from all the 223 workers working in 88 small-scale and informal wood processing industries in Tiko, Mutengene, Buea, Ekona, and Muyuka areas from July 4th to 30th, 2016, using a structured interview and an inspection checklist. Data entry and cleaning was done using excel and exported to Statistical Package for the Social Sciences (SPSS) 20.0 for analyses. The findings revealed that a majority of the woodworkers were males, young and inexperienced, mainly trained through apprenticeship and worked for long hours. There was generally lack of knowledge and poor practices of occupational health and safety among respondents. The findings also showed a very high self-reported injury rate of 86.1% among woodworkers within the past 12 months which was significantly associated (P<0.05) with woodworkers’ age and practice of OHS. Major occupational injuries reported by the respondents include cut, sprain, backache, chronic joint, fracture of the upper and lower limbs and burns. The major sources of injuries included carelessness, insufficient use of PPE and fatigue caused by overworking. Further findings showed that most study sites did not comply with the Cameroon OHS Order No. 039/MTPS/IMT of 26 August 1984 as over half of the study’s workshops had narrow walkways with obstacle and were situated in dilapidated structures. Most workers were exposed to high vibration and noise, excessive heat and cold, hazardous chemicals and ergonomic hazards. The study thus recommends that effective measures be put in place to curb work-related injury rate by enhancing health and safety promotion programmes with emphasis on pre-employment OHS training for newly recruited workers, respect the 8 hours per day allocated for work, provide workers with suitable PPE, as well as other accompanying supplies such as appropriate fire extinguishers and first aids. / Health Studies / D.
