Even though nations and organizations were confronted with global health emergencies before such as SARS (2003), H1N1 (2009), and Ebola (2014-2015), many seem to have forgotten the lessons learned on developing fit-for purpose protocols for risk management and communication to protect and care for concerned populations. The COVID-19 crisis reminds us once again that a complete understanding of the basic principles of crisis communication response are essential, and lessons learned from previous events and disruptions are key for protecting citizen’s health and safety and preserving business continuity. The pandemic above all is a wake-up call that our well being is closely tied to the health of the planet. We must accept a hard lesson-markets depend on the health of our citizens and the natural environment. Markets cannot succeed in failing societies. There is not strong evidence that explaining the science of disease can directly change behavior, let alone habits (NASEM, 2016)* The key reasons people do not do things they should are cognitive preferences for old habits, forgetfulness, following the path of least inconvenience, applying politically motivated reasoning, and most importantly seeking information to confirm pre-existing beliefs. This presentation is designed to assist decision makers to identify communication strategies for increasing adherence to protective behaviors that can mitigate the spread of disease and features selected lessons derived globally from the COVID-19 response inclusive of the following: Pre-crisis: communication preparation and training Crisis response: communication response to the crisis Post-crisis: highlights to better prepare for the next crisis and application lessons learned to fulfill commitments made during the crisis response phase *NASEM (National Academies of Sciences Engineering and Medicine) (2016).

The link between work and silicosis has been known for hundreds of years and knowledge that silica can cause lung cancer emerged during the last twenty or thirty years. Each year around the world, about 50,000 people die from lung cancer as a consequence of silica exposure, with a further 10,000 deaths from silicosis. Globally the death toll has risen over the last 40-years as the number of workers exposed has increased, although in high income countries silica-related deaths have been slowly decreasing. Silicosis and lung cancer from workplace crystalline silica exposure can be prevented. However, we have been slow to learn how to effectively manage the risks and quick to forget the lessons of history. During the last forty years we have seen cases of accelerated silicosis amongst stone masons in Scotland, where exposures were 100s of times the permitted levels, and cases of silicosis in people sandblasting jeans or cutting granite tabletops. We really need to change our attitude to airborne dust at work to make it unacceptable. Only by completely eliminating the problem can we prevent these diseases.

Some construction sites encounter difficulties identifying effective controls aimed at minimising respirable crystalline silica (RCS) exposures during concrete cutting and grinding works due to their transient nature. Limitations are also encountered identifying practical controls capable of being transferred from one location to the next. This project evaluated the effectiveness of controls used in a transient environment by obtaining RCS exposure and background monitoring data. Feedback from workers was also received to gain an understanding of the perceived effectiveness of controls. The site was unable to introduce wet methods of works and trialled combinations of engineering and administrative controls and PPE. Certain combinations of control reduced RCS exposures, but were unable to reduce exposures below the workplace exposure standard (WES). Sites may encounter hurdles using wet methods of control however it is important they are trialled in conjunction with other levels of control to reduce RCS exposures below the WES.

An evaluation of worker exposure to respirable dust (RD) and respirable crystalline silica (RCS) found in fly ash during removal of fabric filter bags within the Fabric Filter Cells, was conducted at a coal fired power station. A qualitative survey explored the worker's understanding of the health risks associated with RD and RCS and current controls. The Quantitative measurements within the Fabric Filter SEG resulted in TWA concentration ranges of 0.22 mg/mÂ³ to 25.37 mg/mÂ³ for RD and 0.01 mg/mÂ³ to 1.49 mg/mÂ³ for RCS. UCL values of 30.46 mg/mÂ³ for RD and 0.94 mg/mÂ³ for RCS identifies that workers are at a high risk of developing chronic health conditions. Compressed air tooling was identified as a major contributing factor to high exposure results. The survey data also identified education and respirator fit testing was inadequate. With fly ash needing to be extracted from the production processes of more than 2000 coal fired power stations across the world, the project and its findings will be transferable across the power industry and fabric filter bag house operations.

Occupational exposure limit values for metals and metalloids are decreasing, especially for metals or metalloids identified as carcinogens or sensitizers. Increasingly, size-specific sampling fractions (e.g. inhalable and/or respirable) are prescribed by regulation. These very low OELVs bring challenges to the measurement methods. All portions of these methods, including sampling, sample dissolution and the analytical methods themselves must be optimized dramatically in order to attain lower method detection limits while maintaining high data quality. The learning outcome of this presentation is focussed on understanding the growing challenges in trace-level sampling and analysis for metals and metalloids, focussing on nickel as an example The practical application for IH/OH professionals is to offer help in selecting the right sampling equipment for trace-level metals and metalloids and ensure they understand the importance of proper laboratory analysis in obtaining the results they need for decision making.

This presentation theme will highlight if modern university anatomy laboratories are appropriately managing formaldehyde exposure. The current Australian formaldehyde workplace exposure standards (WES) are 1 ppm time-weighted average (TWA) and 2 ppm short-term exposure limit (STEL). Safe Work Australia recently proposed a TWA and STEL WES of 0.1 ppm and 0.3 ppm respectively. This study was undertaken using personal air monitoring and participant exposure questionnaire data to characterise exposure. Ventilation and personal protective equipment control measures were also assessed. The results highlighted exposure was not acceptable. The TWA and STEL geometric means were measured at 1.1 ppm and 1.5 ppm respectively and Bayesian analysis supported the conclusion. Powered air purifying respirators were introduced to enable further review of ventilation and substitution controls. Modern university anatomy laboratories may need to undertake detailed exposure assessments in preparation of a revised formaldehyde WES.

At the AIOH conference last year in Perth it’s unlikely anyone could have predicted the events that would unfold in the first quarter of 2020. The rapid shutdown of international borders caused an immediate slowdown in the global economy. As the virus spread, lockdown measures forced many workplaces to close or dramatically alter normal operations.There's no argument that the Covid-19 Pandemic created some significant challenges in occupational hygiene leadership and communication.But could these unforeseen challenges be a path forward to a new era in awareness of the importance of worker health and safety? The occupational hygiene community experienced an immediate call to action to develop and communicate control strategies to attempt to allow business and society as a whole to return to some sort of normalcy.....albeit drastically different. This presentation will highlight some of the challenges encountered as our profession had to rapidly pivot from what was normal occupational hygiene practice into Covid-19 management. As a result, public awareness of measures to control hazards in the workplace has never been at a higher level. As we continue to address these challenges by communicating with workers and the public are we paving the path to a much brighter future for our profession?A number of perspectives from global occupational hygiene leaders will be shared to help us all take a breath for a moment and look towards better days.

Currently, COVID-19 is a global pandemic which has disrupted not only the health of communities but also the socio-economic state of the world. In Indonesia, on the 24th April 2020, confirmed COVID-19 cases had reached 8,155, mainly concentrated at eight largest provinces. Perception of COVID-19 amongst Indonesian citizens were studied. An online questionnaire was developed by following a standard questionnaire on risk perception of an infectious disease outbreak (ECOM, 2015) and distributed through social media on first week of May 2020, 2 months after the 1st case in Indonesia.1,067 respondents participated in this study. It was found that the respondents of this study showed a good level of knowledge on COVID-19. Although their perception on the severity, seriousness and number of confirmed cases were high, they showed a moderate extent of anxiety. Moreover, the respondents showed a positive perception of COVID-19 prevention and control. Associated factors such as gender, age, educational background, and occupation were investigated.

Heavy bushfire smoke impacted workplaces in Sydney, regional New South Wales, and many other parts of Australia during 2019-2020. Advice for workplaces was issued by SafeWork NSW. Regional monitoring data from the EPA was available, but was not always useful at specific sites. On site airborne particle testing was conducted using aerosol photometers, with a calibration factor for ambient air. These instruments were configured to send SMS alerts at pre-set alarm levels. Advice on hazardous smoke levels (as PM2.5) has been issued by environmental authorities. Outdoor smoke exposure can be controlled by work scheduling, or respiratory protective equipment (RPE). Indoor smoke can be controlled by the use of recirculating air purifiers with HEPA (high efficiency) filters. After the event, surface smoke deposition can be tested by wipe testing, or micro-vacuum sampling with subsequent optical microscopy.

Fire Fighters are compelled by their employment to take all necessary steps for protecting and saving life and property, whilst preventing and extinguishing fires and when combating hazardous material incidents. As a consequence they may be exposed to a range of chemical, physical, biological, ergonomic and psychosocial hazards in response to call outs, including fires, HAZMAT spills and other emergencies. Their health concerns include cancer risk, cardiovascular risk, physical stress, heat stress, psychological stress, and infections. The acute toxic effects of smoke from fires include lacrimation, upper respiratory tract irritation and impairment of lung function. There are also potential synergistic effects of exposure to oxygen depletion, carbon monoxide and hydrogen cyanide, for example causing asphyxiation. Chronic effects include cardiovascular disease, respiratory disease, and cancer. Pyrolysis products in fire smoke consist of a cocktail of many chemicals including carcinogenic chemicals. The International Agency for Research on Cancer lists carcinogens that may be found in various fire smoke scenarios. Some limited research has shown, in small trials, that firefighting clothing can absorb a range of airborne contaminants that can then be later analysed to determine what was present during a fire event. There are no published studies that could be found relating to airborne exposures of Australian firefighters, and limited studies internationally, during major fire activities including either structural or wild fires. This presentation will discuss the initial results of a pilot study to identify some of the hazardous materials Fire Fighters are exposed to from constituents of the smoke of a structural fire.

While inspecting an offshore drilling rig operating on the North West Shelf off the coast of Western Australia, inspectors observed uncontrolled airborne hazardous chemicals during chemical mixing at the sack room manual hopper. The airborne, uncontrolled chemical mixture presented an occupational health risk to members of the workforce. The inspection, including discussions with the workforce regarding the effectiveness of the implemented safety management system and associated controls, found the risk of exposure to hazardous chemicals was not managed to as low as reasonably practicable. Enforcement action was taken firstly to address the immediate threat to the health and safety of workers by ensuring the workforce was provided with suitable respiratory protection, and secondly, to implement a series of controls at the source to reduce the risk of exposure to members of the workforce to as low as reasonably practicable (ALARP).

Mercury is a highly toxic, naturally occurring element encountered in various chemical and elemental forms throughout nearly all Oil and Gas production and processing systems. The Presence of mercury creates substantial health, safety and environmental issues that reduce efficiencies in maintenance activities and considerably add to costs in demolition. Understanding accumulation, distribution, and the sorption dynamics of mercury throughout process is instrumental in the application of improved chemical decontamination and waste management techniques used during plant turnarounds and the clean out of gas processing equipment. This paper aims to address these issues in the oil and gas industry by utilising cutting edge chemistry to remove the mercury up to 99%. The outcomes benefit the environment and people who are maintaining plant and equipment that previously was mercury contaminated. This technology is transferable to other industries that contain mercury contaminated equipment.

RESP-FIT is the exciting new AIOH program to accredit competent respiratory fit testers, approve training providers and trainers. A significant aspect of the practice of occupational hygiene in certain industries is the management of respiratory protective equipment programs, including fit testing. There is clear evidence that real world respiratory protective equipment (RPE) protection factors are improved when there is an RPE fit testing as part of a respiratory protection program (RPP). The specifics of RPE fit testing are coming under increasing scrutiny with such high reliance in many workplaces on RPE as a control and the increased respirator use due to the pandemic. However, there is currently no clear guidance in Australia on what defines a good RPE fit test and unfortunately, there are plenty of examples of poor fit testing practice and mis-information in many industries. Most industries/companies currently use their own definition/level of a competent person, but what is a competent person varies significantly between industry/companies. Over the past 2 years, the AIOH have had a working group to develop an industry self-regulated RPE fit testing training and accreditation program in close co-operation with many stakeholders to fill this gap in guidance and best practice to provide the means for improving the quality of RPE fit testing in Australian workplaces. This new program is called RESP-FIT. This presentation will cover the details of the new AIOH RESP-FIT program.

In the 2012 version of the World Health Organizations “Prevention of hospital-acquired infections-A practical guide” the recommended infection control team listed everyone from laundry service, housekeeping, and food service to physicians, pharmacists and nurses. Nowhere in the 72-page document did they mention the need for an occupational hygienist. With hospital acquired infection rates in industrialized countries ranging from 2-15 percent, and occupational exposures to hazardous infectious agents leading to significantly elevated illness in healthcare workers, the capabilities and knowledge of occupational hygienists is a greatly underutilized resource. Industrial hygiene methods of evaluation and control can be implemented in a number of technical areas that can substantially reduce both patient and worker infections, illnesses, and associated costs. In light of the recent COVID-19 global pandemic the need for ongoing input and service in occupational hygiene has become even more apparent. This presentation will provide an overview of where we have come from, and identify the roles occupational hygienists need to fill, in order to become part of the ongoing and permanent infection control team in health care moving forward.

Over the years the approach to hygiene monitoring has been largely based on the assumption of homogeneous similar exposure groups (SEGs). As workers multi-skill, SEGs are becoming more diverse and the monitoring data increasingly larger. This in turn is leading to high levels of variation in the data. Is too much time now being spent sampling to achieve better uniformity to meet perceived compliance requirements or is there a more pragmatic approach that can re-focus the hygienists time back to field assessments and control management rather than data collection?

Adopting a holistic approach to her work, she has honed her skills in project management and partnering with multidisciplinary teams.
Candice is passionate about driving better worker health outcomes through continuous improvement, harnessing technology and a strong focus on stakeholder engagement. Recently, her work has centered on the effective application of real-time and video technologies to ensure critical controls are in place to protect worker health.
The problem: Pressure for workplaces to become more agile and responsive to evolving customer and economic demands has led to significant changes in job role requirements. Increasingly, work occurs across multiple areas and tasks, with mutli-skilled workers contributing to improved operational efficiency. As a result, similar exposure group (SEG) sampling results can be highly variable, making it difficult to identify the underlying cause of high exposures and recommend effective controls. A new approach to exposure assessment: Real-time exposure and video monitoring enables a shift in focus from SEGs to high exposure areas and tasks, along with the identification of exposure sources for the development of effective controls. The technology is practical and versatile with occupational hygiene applications including: mapping high exposure areas and tasks; prioritising control measures; assessing control effectiveness; investigating sampling exceedances, developing job role profiles; informing training packages and combining multiple inputs for holistic personal exposure assessment. Key Benefits (immediate and evolving): This technology is more efficient and visual than traditional techniques for exposure and control assessments. The outputs enable clear and effective communication, training and feedback for stakeholders and inform the development of control solutions to drive better worker health outcomes. Real-time and video exposure assessment technology is an essential, accessible tool that enables occupational hygienists to become more effective and responsive in today's rapidly evolving workplaces.

Graduate Engineer, Boral
I am a chemical engineer in Boral's graduate program within their Quarries and Recycling division. I've been involved in dust monitoring across several sites, which has introduced me to the world of occupational hygiene. I'm passionate about keeping people safe and healthy at work, and making a worthwhile contribution to improving working conditions. I'm keen to learn more about the role of occupational hygienists!
Using real-time dust monitors in quarries provides a better understanding of how dust is generated on site and the ways in which workers are exposed to dust. Combining the data collected from real-time dust monitors with video footage gives valuable insights to both the management team and workers, encouraging collaboration and input from all levels to find suitable solutions and understand the dust environment they are working in. Compared to traditional monitoring methods, the ability to obtain real-time information allows for sites to quickly establish current working conditions and make well assessed decisions and improvements. Targeted control measures can be developed then swiftly implemented and tested for effectiveness, new activities monitored, and site specific dust maps generated. It is proving to be an extremely useful tool to assist with dust management and reduce worker exposure, which is of considerable focus within the quarrying industry, especially during the present time.

The exposures of workers to respirable dust (specifically the crystalline silica component) can have a significant impact on workers’ health. Traditional, and legislatively mandated, monitoring for respirable dust and crystalline silica has been undertaken by sampling in the worker breathing zone over the period of a worker’s shift providing a Time Weighted Average (TWA) result based on the volume of air sampled.Whilst the sample provides a result that may be compared to the relevant Workplace Exposure Standard (WES) it does not provide any information as to the events that occurred during the monitoring period.Samples taken in the traditional sense must be sent away to a lab and analysed before results will be known. Worker’s understanding of what risks are associated with their activities and how to control them, is essential to enhance their health and safety. A variety of applied training methods have been utilised within the wider industry, and the common method of using a training class has been found to have a limited effect due to a number of factor. Hence, more specific training is needed to increase awareness and educate the workers about their exposure. To address the pitfalls in training models that primarily rely on classroom based or after the fact training. By undertaking a sampling and training procedure whereby sampling is undertaken for respirable dust using a real time monitor and a personnel video recording device (GoPro) which recorded the subjects tasks for the duration of the sampling period. The information gathered from both devices can be combined using a software package (EVADE). This information when analysed, with the help of the worker to identify the activities/work captured on the video that co-insides with measured respirable dust levels. This evaluated video and data can then be used to educate the workers and work group around the high exposure tasks by being able to both graphically and visually demonstrate the impact certain tasks have on exposure. Through this education process it is expected that workers will have an increased awareness of the sources of exposure to respirable dust and thus present with either a change in behaviour or a greater intention to change in adverse and hazardous behaviour (as it relates to respirable dust exposure).
Acoustical Engineer, 3M Personal Safety Division
Cameron Fackler, Ph.D., is an Acoustical Engineer with 3Mâ€™s Personal Safety Division where he conducts research and development for the next generation of hearing protection devices. He is especially interested in hearing protection for impulsive noise and fit testing of hearing protectors for individual users. Cameron is a member of the American National Standards Institute (ANSI) working group on hearing protector attenuation and has contributed to the development of standards for assessing the performance of hearing protection devices in continuous and impulsive noises. He is a member of and has presented his research on hearing protection devices at meetings of the Acoustical Society of America (ASA) and the National Hearing Conservation Association (NHCA).
Impulsive noise presents unique challenges for hearing conservation, with peak sound pressure levels that may be 170 dB or higher. In addition to the very high peak levels, many impulsive noise exposures are interspersed with periods of relative quiet, where situational awareness or the ability to hear low-level sounds like speech may be important. This presentation will define impulsive noise and discuss challenges for measuring and characterizing impulsive noises. Hearing protection for impulsive noise and the measurement of impulsive noise attenuation will be explored. Finally, pros and cons of various types of hearing protectors for impulsive noise will be discussed, including how some types may provide impulsive attenuation along with enhanced situational awareness.

An acoustic engineer for over 30 years, I've spent many years working in occupational and environmental noise in Western Australia, providing training, consulting, and technical support to occupational hygienists, environmental health officers, consultants, industry and government.
After 8 years at the University of Salford Department of Applied Acoustics researching noise in the military environment, a move to Perth in 1997 broadened my experience and interest in workplace noise, and for over 20 years I've presented the DMIRS-approved Noise Officer Course and a range of other short courses in both occupational and environmental noise.
Occupational noise-induced hearing loss (ONIHL) has been the most prevalent workplace illness in Australia for decades. We know how noise damages hearing, we know the human and financial costs, and we know what to do about it in many cases - yet the incidence of ONIHL continues unchecked. Why is this? There are many reasons why noise is commonly overlooked as a hazard and a major cultural shift is required to significantly reduce exposures. This presentation identifies some of the barriers to improvement and suggests some paths forward.

COVID-19 disease is caused by a transmissible Coronavirus (SARS-CoV-2). This virus has jumped species and is rapidly adaptable. The virus has good environmental stability and is easily picked up on hands from contaminated surfaces or when an infected person is in close personal contact with an unifected person (touch). Once on the hands of an uninfected person, the virus can find its way to the intended receptor cells, most frequently in the mouth, oral palate, nasal lining or eyes. That’s because most of us touch our faces at least 20 to 40 times every hour. There is complexity in the selection of Hand Sanitiser because the regulatory arrangements are disjointed. There are five separate options for hand hygiene. At the top end are TGA registered products with high levels of certainty over safety and efficacy. At the other end at products which do not have any mandated requirements for either safety or efficacy. At this end, the products can fit into either the Industrial Chemicals bandwidth, or the Cosmetic products requirements. Ironically, it is illegal to make virucidal claims on any Hand Hygiene product. This presentation will review the science on hand hygiene and spread of infectious organisms via unwashed hands. There will be an outline of the regulatory arrangements and clarity given on expected product performance and appropriate pathways for hand hygiene compliance in the workplace.

Inhalation of respirable crystalline silica (RCS) may result in silicosis and/or lung cancer. The extreme variability of silica forms, depending on their source and preparation methods, has so far hindered a comprension of the molecular mechanisms that trigger such negative outcomes. Using a set of synthetic and natural quartz samples, we have now identified a unique subfamily of surface moieties that sit on the quartz surface and act as the determinant of silica particle toxicity. These moieties, namely pairs of "nearly-free silanols" (NFS), appear on the surface of quartz particles when crystals are fractured, and their amount can be modulated by thermal treatments. The peculiar spatial arrangement of these surface species was demonstrated to be the initiating event in the lytic interaction between quartz and cell membrane components and initiated RCS toxicity in vivo.

Background: Engineered stone (ES) workers have increased rates of silicosis and scleroderma. Notably accelerated silicosis has been observed and thought to be related to ES constituents such as crystalline silica and binding resin. The aetiology of ES-related silicosis initially involves interaction of stone dust with interstitial and intracellular lung fluids. There appears to be no reported biosolubility study of ES dusts. The aim of this study was to investigate the biosolubility of engineered stone dusts, of variable composition, including both high and low resin content. Method : A range of engineered stone dust samples, obtained by low temperature comminution of commercial ES, were reacted with simulated lung fluids (SLF), namely artificial lysosomal fluid (ALF) and Gambles solution, for periods of 3 hours, 1 week, 2 weeks and 4 weeks. Changes in organic and inorganic content of SLF and stone dust were assessed. Results: Early findings indicated that the degree and type of metal ions release varied with engineered stone type and the type of SLF. In general, greater changes were observed with ALF, likely due to lower pH and a greater potential for metal chelation. Conclusion: A systematic investigation of the engineered stone dust is required to understand the pathogenesis of accelerated silicosis.

Early studies of the hemp fibre production demonstrate a relationship between inhalable dust exposure and respiratory conditions such as byssinosis, chronic asthma and chronic obstructive pulmonary disease (COPD). More recently, attention has focused on the allergenic properties of C. sativa L. pollen exposure, as well as healthy and safety hazards on outdoor recreational cannabis farms in the United States. It is evident that there are multiple biological, physical and chemical hazards associated with cannabis cultivation and manufacturing procedures, some that are inherently unique to the plant. A greater understanding of the aetiological properties of medicinal otherwise referred to as drug or hybrid type, C. sativa L. containing greater than 0.35% delta 9-tetrahydrocannabinol (THC) content is required to determine if exposure control is required, including the development of an occupational exposure limit (OEL). Recently there has been a rapid development of the international medicinal and recreational commercial cannabis industry. The downgrading of Cannabis sativa L. to a controlled substance, in many countries, when prepared or packed for human therapeutic use, has heralded the introduction of a the medicinal cannabis industry. This presentation will present the toxicology of potential exposures in the hemp and related medicinal cannabis industries.

Indoor environmental quality (IEQ) is a term that refers to the quality of a buildings environment in relation to the health and wellbeing of the buildings occupants. The health and financial benefits of a healthy indoor environment have been well documented and linked to occupant productivity and wellbeing. Components of indoor environment quality include air quality, lighting and noise. Activities undertaken in a dental facility have been demonstrated to contribute worker exposures with possible detrimental health effects including particle and Total Volatile Organic Compound (TVOC) generation, noise and lighting. While various studies have looked at worker exposures to these various components, so far there are no studies that look at all factors of indoor environment quality. This paper will present the findings of exposure monitoring that was undertaken in a dental facility in Darwin, to determine exposures of workers to indoor air contaminants, noise and lighting.

In the United States, there have been fatalities and hospitalisations associated with heat-related illnesses within the rapidly growing courier delivery service. This study investigated the potential contributing factors, such as airflow, temperatures, and colour on vehicles. Courier services however do more than just drive as part of the work. Each delivery is unique due to the variations in the manual handling requirements with regards to package dimensions, weight and carry distances. This will also impact on the metabolic load and subsequently on the thermal balance. If not managed correctly, this could lead to heat-related illnesses. Parameters were measured using multiple WBGT monitors and an anemometer. This information was utilised to model the physiological impact using a rational index. The results have been used to develop a risk assessment tool based on the AIOH Basic Thermal Risk Assessment model. The modified assessment has been designed to cater specifically for the courier driver and their tasks.

We have conducted several projects around climate change associated heat wave impacts and adaptation strategies of vulnerable populations of outdoor workers in Africa (Ghana and Zimbabwe). Occupational heat stress has also been assessed in the Australian resources sector with a focus on quantifying heat exposures of various occupational groups and the loss of acclimatisation status by fly-in, fly-out (FIFO) workers where their time spent at home is in a cool climate. Interventions such as ingestion of ice slurry to reduce core body temperature, protective clothing and heat exposure control of firefighters have been assessed. The results of this work will be presented with a focus on what can be learned from the different populations in terms of adapting to extreme heat wave events, particularly for outdoor workers.

Blesson has a background in Health Science (Public Health) with First Class Honours and recently completed his PhD within the School of Public Health at the University of Adelaide. His PhD project titled "Worker's Health and Safety at High Temperatures: new perspectives on injury prevention", part of a multi-institutional Australian Research Council (ARC) grant examined the impacts of extreme heat on work-related injuries in Australia. His research interests include work-related injury epidemiology and prevention, climate change, workplace heat exposure, and infectious diseases. He has extensive experience conducting research using large administrative surveillance datasets and surveys. His recently completed work at the Bureau of Meteorology examined the correlations between demographic profiles, dwelling profiles, existing health risks factors, and the human health impacts of heatwaves. Currently he is part of a team examining the burden of disease of climate-sensitive or heat-attributable diseases and injuries in Australia.
Hot working conditions can lead to heat-related illness and increase the risk of physical injuries. To better understand the injury phenomenon, mixed-methods research was undertaken using workers’ compensation claims, national online surveys of workers, health and safety professionals and representatives, interviews with workers, and a telephone complaints database. This paper integrates the findings into a conceptual model of psycho-behavioural and physiological changes in workers induced by heat stress. Injury risk factors relate to work, worker and workplace. The qualitative evidence indicates limited awareness of injury mechanisms in hot weather. In contrast to traditional risk factors for heat-related illness, risk factors for injury include interacting hazards in particular tasks; altered work practices, vigilance and reduced use of PPE as a result of heat exposure, dehydration and fatigue; and moderately hot conditions rather than extreme heat representing the greatest injury burden, in indoor as well as outdoor environments. Injuries, themselves, are diverse including traumatic injury and chemical-related injury, leading to extensive misclassification in current injury reporting systems. Importantly, heat-related injuries, such as falls from height or hand injuries, can occur before the onset of frank heat illness.

Mining regulations in Western Australia require that undiluted diesel engine exhaust is to be tested in underground mines. As a minimum this shall be at intervals of no more than 250 hours, or 1 month if no hour meter is present. As consultants OHMS Hygiene have been carrying out monthly diesel exhaust emissions testing for 13 sites across Western Australia between 2015-2020. This paper will review the de-identified data to determine trends in why sites are exceeding the limits for EC (Elemental Carbon) and NOx (Nitrogen Oxides), and what sites have done to manage the diesel engine exhaust emissions. This research will help organisations understand how they can reduce their diesel engine exhaust emissions and therefore prevent exposure to their underground miners.

Dr Jennifer Hines is a Certified Occupational Hygienist with over 20 years’ industry experience in the mining, manufacturing and Defence sectors. She has a Masters in Occupational Hygiene and a PhD from the University of Wollongong. She is currently a consultant Occupational Hygienist and an academic at the University of Wollongong. Reducing worker exposure to contaminants in the underground mining environment has been a focal point of her career.
A particular aspect Jennifer has focussed on is controlling diesel exhaust emissions through maintenance of diesel engines, and importantly how this reduces the exposure risk to the workers. She has conducted significant work on proving there can be a significant reduction in employee exposures to diesel emissions and substantial savings in fuel use by conducting emissions based maintenance on diesel engines. This double benefit provides added incentive for companies to adopt emissions based maintenance.
There are many widely used and effective controls to reduce worker exposure to diesel emissions.Recent research has proven that implementing an Emissions Based Maintenance (EBM) system is a doable and realistic control for limiting occupational exposure to diesel particulate matter (DPM) at mine sites.This control falls within the engineering category of the Hierarchy of Control as changes are made to the engine and/or exhaust system to reduce the contaminants exiting the exhaust before it reaches the workers. This presentation will briefly cover findings of a site based, practical research project where EBM was implemented at one site, compared to a control site where no additional maintenance was conducted.Included will be strategies on how a similar control system can be duplicated elsewhere and other useful tactics can be employed to reduce DPM exposure. DPM and reducing diesel exhaust is the focus of significant research.There are numerous ways to reduce and quantify diesel exhaust.EBM is one practical, inexpensive method that has been proven to be successful.

Long term exposure to high-amplitude whole-body vibration is associated with adverse health effects, especially back pain. Operators of surface mining equipment are known to be exposed to whole-body vibration. Vibration amplitudes experienced by operators are dynamic, a function of equipment design; seat design, condition and adjustment; roadway or ground conditions; vehicle maintenance; activity being undertaken; and operator behaviour. Ad hoc measurements are consequently of limited utility in assisting mines to manage exposures to the hazard. This paper describes the background to the design and implementation of hardware and software which enable continuous monitoring of floor and seat accelerometer installed in earth-moving equipment at a Queensland coal mine. The data have potential to enable evidence-based decisions regarding the implementation of control measures
