Social Impacts Of Climate Change And Occupational Heat Stress And Adaptation Strategies Of Mining Workers In Ghana, Victor Fannam Nunfam

Theses: Doctorates and Masters

Excessive heat exposure due to rising temperatures associated with climate change adversely affects workers’ health, safety, productivity, and psychosocial well-being in occupational settings. In the hot and tropical regions of developing countries, long hours of physically demanding work, coupled with inadequate adaptation policies to climate change, increases the occurrence of heat-related illnesses and injuries, and contributes to the loss of productive capacity, poor decision making, and other negative effects on the social well-being of workers.

Based on the theories of social impact assessment, risk assessment, adaptation and resilience planning, this study assesses the social impacts of climate change and occupational …

Does Facial Physiognomy In The Context Of Anoccupational Safety And Health Message Predict Outcomes?, Ian Parker

Theses: Doctorates and Masters

Physiognomy, the practice of looking to another person’s outward facial appearance to unmask the inner character of that person, has had a diverse historical impact within art, medicine, theology, anthropology, law, criminology, political history, psychology, psychiatry, and popular culture, since it was conceptualised in Greece during the 5th and 4th centuries B.C (Physiognomy, 1999-2009, 2009a). Aristotle, the prominent Greek philosopher, penned many chapters on physiognomic properties and touched upon strength/weakness, genius/stupidity, and other trait characteristics and their opposites in so far as such characteristics were associated with facial form (Physiognomy, 2006, 2009b).

In more modern times, facial recognition and evaluation …

Ethnographic Insights Into Safety Communication For Frontline Workers, Kelly Jaunzems, Lelia Green, David Leith, Christine Teague

Research outputs 2014 to 2021

Recent calls for organisation studies to embrace ‘the practice turn’ (Whittington, 2011) have expanded into an understanding of the potential for ethnographic research in occupational health and safety (OHS) research (Pink et al., 2016). The ethnographic project described here, with fieldwork conducted between 2008 and 2010, is one element of this growing appreciation of the potential for qualitative research in industrial settings. Ethnographies have not often been used in OHS settings, and ‘much practicebased knowledge remains undocumented, informal, unspoken and thus unaccounted for’ (Pink et al., 2016, p. 27). This study was motivated by an aim to make explicit the …

An Investigation Into Dust, Gases And Vapours Expulsed During The Oxidation Of Pyritic Black Shale, And Their Potential For Impacting On Employee Health, Tristan Lynn

Theses: Doctorates and Masters

Pyritic black shale (PBS) is occasionally extracted as a waste product of iron ore mining in the Pilbara region of Western Australia. Mineralogical studies such as Brocks, Summons, Buick, and Logan (2003) of the PBS located at Mount Tom Price Operations have established that PBS can contain elevated concentrations of pyrite, carbon, bitumens, polyaromatic hydrocarbons and volatile organic compounds (VOCs). The natural oxidative weathering of PBS can cause exothermic reactions leading to the shale reaching temperatures that cause the expulsion of toxic gases such as hydrogen sulphide, sulphur dioxide, methane and carbon monoxide.

Regulating Small Firm Safety Via The Supply Chain: Implications Of The Australian Work Health And Safety Act, Susanne Bahn, John Kitching

Research outputs 2013

The impact of the Work Health and Safety Act (WHS Act) highlights subcontractor working practices. By motivating contractors to influence subcontractor working practices, regulation influences the latter’s health and safety performance. Indirect routes of regulatory influence, working via supply chains, might prove to be a more effective means of improving small firm health and safety than placing obligations upon subcontractors directly, and limit contractor exposure to their new liability for subcontractor breach.

Australia strives to be a world leader in safety practice however improving safety cultures to reduce work-related injuries in the hazardous environment of the construction industry is a continual challenge. It is particularly difficult in Western Australia (WA) where the industry is engaging with the second development boom this century, often in isolated locations, and simultaneously adapting to the national harmonisation of OHS regulations. In 2006, Worksafe WA introduced mandatory certification in safety awareness training for all employees, before they could begin work on a construction site. This paper reviews the impact of this training on the construction industry, presenting …

The Unmet Promise Of Occupational Health And Safety Harmonisation: Continued Complexity For Small, Multi-Jurisdictional Firms, Susanne T. Bahn, Susan Mayson, Rowena Barrett, Llandis G. Barratt-Pugh

Research outputs 2013

Harmonisation of state-based occupational health and safety (OHS) regimes is a Council of Australian Governments (COAG) initiative designed to ‘cut red tape’ for Australian firms. However Western Australia’s, South Australia’s and Victoria’s lack of harmonisation makes it problematic for firms that conduct business in multiple jurisdictions. In this paper we investigate what impacts harmonisation has on firms generally and specifically smaller, multi-jurisdictional firms. First, we look at the requirements of the model WHS Act and what it said about managerial responsibilities for OHS. We focus on the due diligence clause which places personal liability on company directors or persons conducting …

Harmonisation Of Construction Health And Safety Laws In Australia, Manikam Pillay

Research outputs 2013

For over four decades all states and territories in Australia have maintained their own and separate set of laws for the management of health and safety risks in construction. This resulted in at least ten different sets of health and safety legislation. Responding to calls for national uniformity, a harmonised set of laws wer issued in 2011 by the Federal Government, in the form of Model Work Health and safety Act and Regulations. These, together with industry-specific codes of practice, are expected to provide construction organisations their first ever common set of standards and benchmarks across the states and territories …

The Impact Of Management Styles Upon Organisational Change And Safety Cultures, Susanne Bahn, Llandis Barratt-Pugh

Research outputs 2012

In this paper we discuss the findings of two large studies conducted during 2005/06 that illuminated the role of managers as change agents. We draw the findings together to conceptualise and model the leadership styles and behaviours that appear to be successful in reshaping organisational safety culture. The first study identified the instrumental influence that managers have on the safety culture within organisations. The second study revealed the influential role of managers as change agents during a cultural change initiative when they applied a flexible approach using formal and informal agencies of change. The paper situates these two studies in …

Research outputs 2012

Female hairdressers in Western Australia were surveyed to determine the occurrence of health problems that may be associated with their work environment. The cohort of 238 hairdressers reported poor health behaviours including a poor dietary and fluid intake; a high prevalence of smoking; and a low level of glove usage when undertaking wet work and handling non-discolouring chemicals. Younger hairdressers were found to be most at risk of increased respiratory illness, musculoskeletal problems, skin conditions, bowel issues and general poor health. When compared with data obtained from the Australian Longitudinal Study on Women’s Health (ALSWH), younger hairdressers reported a higher …

Limitations Associated With The Pooling Of Historical Data Sets: An Analysis Of Dust Monitoring Data Collected At A Typical Remote Australian Mine 2004 - 2008, Jacques Oosthuizen

Research outputs 2012

Dust monitoring data collected over a period of 5 years at a remote Australian mine site were pooled in order to create a large data set for analysis. Results adjusted for a 12-hour shift were compared to exposure standards and 90% of the respirable and 97% of the inhalable dust samples were found to be within the exposure standards. Median values appear to better describe exposures than the mean which is influenced by outliers. There was a declining trend in respirable dust results over time. However, inhalable dust levels remained fairly constant over the sampling period. Inhalable dust levels were …

Hard Or Soft? The Relationship Between Power And Organisational Incident Rates, Susanne Bahn, Llandis Barratt-Pugh

Research outputs 2012

This paper examines the power that managers have to impact on workplace safety and how in mixed method studies our preconceptions about the hardness and softness of the relevant data may be misplaced. The civil construction industry (CCI) in WA provides the case for this discussion. Workers in this industry are constantly battling between safety compliance and production pressures in an era of economic boom. The examination of 3,882 incident reports, upon which this paper’s conclusions are drawn, revealed that these ‘‘hard’’ data may often obscure incidents that occur as organisations may be pressured into providing reportable incident figures that …
