Analysis of employee participation in occupational health and safety activities in a cement manufacturing organisation in South Africa

Brijlall, Mathurapersadh 11 1900 (has links)
Globally organisations face unacceptable levels of fatalities that translate into financial losses and bad publicity, which can be attributed to the inadequate employee engagement in decision making in daily work activities. This study explores the participative role of employees in the management of occupational health and safety (OHS), and investigates the impact of employee participation on the decision making processes that create a safe workplace. The joint labour-management committees encourage employee participation that improves the injury and disease prevention programs. Four participative approaches exist in the decision making processes, namely Directed Participation, Involvement, Pro-active Participation and Ownership, that are interrelated and integrated with the decision making process. When employees are required to abide by set guidelines and procedures, Directed Participation is appropriate. This has been observed to occur with little or no input from employees, whilst the application of legislation requires the process of involvement where critical decisions are made outside the domain of the employee. The pro-active participation process entails the sharing, consulting and making of joint decisions, which is most suitable in the Safety Health and Environmental committees, ensuring the process of Ownership empowers employees to champion the OHS activities. In OHS management there are instances when numerous participative approaches are utilised simultaneously to make decisions. All employees, both blue collar workers and management have a positive influence in creating a safe workplace, with the likelihood of older and experienced employees participating more than their younger counterparts in the decision making processes within the various OHS forums. Also, the more employees assume full responsibility for their health and safety, the greater is their influence to find solutions to the safety challenges. Additionally, making joint decisions to create a safe workplace will, in turn, encourage employees to participate more. The use of the participative approaches results in an improvement in the iii decision making processes within S.H.E. committees and OHS management processes, thereby making a positive contribution. More research is recommended to explore the relationships between employee participation in decision making and the compliance to OHS legislation, employee training, the safety culture and the influence of trade unions. / Business Management / DBL

Risk assessment and the effects of overhead work - an automotive industry example

Elliott, Andrew Brent January 2008 (has links)
The focus of this investigation was an analysis of the work demands being placed on South African automotive industry workers as there is a recognised problem with regard to the prevalence of musculoskeletal disorders (MSDs). Preliminary work was conducted to highlight the dominant risks and areas which elicited higher numbers of MSDs within the chosen automotive plant. An area of concern was highlighted through medical record analysis and the use of risk assessment tools, thereby prioritising the need for ergonomic intervention. In particular, the effects of varying restricted and overhead work heights on the biomechanical, physiological and psychophysical responses of an individual were investigated. Twenty-eight subjects were required to complete sixteen conditions. The conditions consisted of the adoption of restricted and upright overhead static postures, with half requiring the holding of four kilograms of weight in the hands and the remaining eight conditions having no weight. Testing was carried out using an electromyography unit, ergospirometer and a perceptual Body Discomfort Map and Scale. This involved a habituation and testing session. The results of the testing revealed the biomechanical and physiological responses were dependant on the change in height. Body discomfort was also shown to be variable over the changing height conditions. This indicates that there is a significant effect of height on an individual’s responses during overhead work. The extreme restricted (-200mm and -100mm) and upright (+300mm and +400mm) overhead conditions within this study were limiting, as they elicited the highest muscle activation, physiological responses and body discomfort ratings. Positions that are preferable to adopt, which were identified from the results in this study, indicate conditions closer to head height (0mm and +100mm) were favourable. The results therefore illustrate how awkward working postures during work are likely to elicit higher demands from an individual, which could lead to an increased risk for the development of a musculoskeletal disorder. The added factor of weight elicited significant results over all variables, excluding a respiratory The focus of this investigation was an analysis of the work demands being placed on South African automotive industry workers as there is a recognised problem with regard to the prevalence of musculoskeletal disorders (MSDs).

Developing and evaluating a coaching program to improve safety leadership

Esterhuizen, 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 & Organisational Psychology / D.

Occupational blood and body fluid exposure incidents amongst undergraduate medical students over a period of 5 years

Essop, Ziyaad Hoosain 12 1900 (has links)
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.

Effectiveness of health and safety training in reducing occupational injuries among harvesting forestry contractors in KZN

Nkomo, Gladys Hloniphile January 2016 (has links)
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

Knowledge, attitude and practice of coal mineworkers pertaining to Occupational Health and Safety at the Leeuwpan Mine in Mpumalanga Province, South Africa

Mavhunga, Khuthalo 21 September 2018 (has links)
MPH / Department of Public of Health / The occupational health and safety of coal mine workers is one of the major occupational challenges in the mining industry. Coal mine workers face the looming perils of potential falls of volatile rocks, the ergonomic challenges caused by bending and lifting heavy objects in their daily work, the challenges caused by inhaling coal mine dust which can cause coal workers' pneumoconiosis (CWP) and a plethora of other hazards in both underground and open cast mines on a daily basis. The aim of the study is to assess the knowledge, attitude and practice of coal mineworkers pertaining to occupational health and safety at the Leeuwpan mine in Mpumalanga province of South Africa. The study adopted a quantitative, cross sectional descriptive design. Self-reported questionnaires with closed-ended questions were administered to the eligible participants. The study targeted the 3200 coal mineworkers who were employed at the Leeuwpan mine in Lephalale. A sample of 356 mineworkers was used as derived from Slovin’s formula and data was collected over a period of 5 days at the Leeuwpan mine. Measures to ensure validity and reliability were ensured and ethical considerations were observed. The Statistical Package for Social Sciences (SPSS) version 23.0 was used to analyse the data. Results and recommendations are based on the findings of the study. / NRF

Managing and implementing occupational health and safety policies in selected Tshwane South primary schools, Gauteng Province

Ferreira, Jenet 01 1900 (has links)
Occupational Health and Safety focuses on the well-being of individuals or groups of people in the workplace. Barnett-Schuster (2008:1) states that Occupational Health and Safety is a concept compiled from many different disciplines. Among others, it includes: biological hazards, physical hazards, chemical hazards, mechanical/electrical hazards and psycho-social hazards. The employer has to understand that Occupational Health and Safety should follow a holistic approach. Occupational Health and Safety is a Constitutional imperative – a command, - not a request. Chapter 2 of the Constitution of South Africa no. 108 of 1996, The Bill of Rights provides protection to such an extent that human dignity may remain intact. Therefore, compliance with Occupational Health and Safety legislation is of cardinal value to any organization or business. An organization or business can also improve their financial standing and public image by complying with Occupational Health and Safety legislation. Occupational Health and Safety in the workplace is guided by the Occupational Health and Safety Act of South Africa no. 85 of 1993, which was implemented in 1994. The Occupational Health and Safety Act further aims to present clear explanations on concepts related to Health and Safety and enables both employers and employees to gain an understanding of their distinct responsibilities. Occupational Health and Safety is a concept that has been around for decades – especially focusing on the mining sector of South Africa. Occupational Health and Safety is observed in the South African technical schools. Statistics from the Children’s Institute show that 350 000 of these children are currently not attending school. In most cases, many parents/guardians do not take the time to assess the safety of their children at school before enrolling their child. This assessment should not only be looking at security measures applied in the school, but if and how true Occupational Health and Safety measures are in place. Occupational Health and Safety (OHS) is measures put in place so that learners/children are free from risk, injury, disease or harm. The lack of Occupational Health and Safety in South African schools is in direct conflict with the Constitution of South Africa. As stated earlier, Occupational Health and Safety is a Constitutional imperative which is the responsibility and the right of each individual in South Africa. The lack of Occupational Health and Safety in South African schools is a human rights issue based on the dignity of children. The lack of Occupational Health and Safety in South African schools can be seen as a policy flaw. This study intends to create a holistic view of the managing and implementing Occupational Health and Safety in the South African school environment. Occupational Health and Safety is an integral part of teaching and learning. The research problem addressed in this study is: “How School Management Teams (SMT) experience, manage and implement Occupational Health and Safety policies in South African schools?”. The main aim of the research is to investigate how School Management Teams (SMT) experience, manage and implement Occupational Health and Safety policies in South African schools. By exploring Occupational Health and Safety in South African schools, this study would strive to obtain clarity on whether enough is being done to ensure the health and safety of learners in the school environment by means to explore the current Occupational Health and Safety management in the South African schools, identify the guidance provided on the Occupational Health and Safety implementation policy, investigate provisions for continual assessment of the process of the Occupational Health and Safety policy and provide recommendations for the lack of Occupational Health and Safety in South African schools. / Educational Leadership and Management / M.
