Winners of 2024 Poster Prize winners agree with the AIOH Workplace Exposure Assessment Committee on RCS
Congratulations to the AIOH Workplace Exposure Assessment Committee (WEAC) for their insightful and significant work in the production of the position paper Respirable Crystalline Silica and Occupational Health Issues, released late last year. It was reassuring to read that the conclusions of the position paper were in line with the independent research and findings at the Perth Conference of the AMCOSH best conference electronic poster award winners, Pieter Bertier and Steven Verpaele: An evaluation of validation schemes for the direct-on-filter X-ray diffraction method for analysis of respirable crystalline silica.
Although an abstract of the poster can be found in the conference proceedings (Poster 26, p. 235), this abstract did not include the findings and extra detail that was presented at the conference. In particular, one of the take-home messages of the electronic paper included the statement: “This implies that for typical samples of 1 m of air, compliance cannot be demonstrated analytically for OELV below 50 µg/m ” . This accords well with the findings of the AIOH WEAC independent position paper. 3

I was surprised to find at the conference that some hygienists were sceptical of the conclusions of the AIOH WEAC RCS position paper, however, the findings of this independent laboratory research should provide reassurance to these members. I expect a full copy of the winning poster is accessible through the AIOH 2024 Conference scientific committee.

Hamish Rae, a Senior Occupational Hygienist at GCG Health Safety and Hygiene, recently published a case study regarding the presence of Hexavalent Chromium VI within exhaust systems of mining trucks The full case study can be found here
Calcium chromate is a powdery, yellow coloured toxic compound that is used as a corrosion inhibitor and to depolarise batteries. It is produced when chromium is presented with an oxidant (such as air or water) at a high temperature ( 200°C or above). This substance contains hexavalent chromium CrVI, which is genotoxic, listed both as an IARC Group 1 carcinogen and a non-threshold genotoxic carcinogen.
Exhaust systems on large mining trucks typically have components manufactured from stainless steel, which contains chromium in some sections to strengthen the steel. Truck’s exhaust systems (particularly with turbos) can reach temperatures of greater than 200°C Lagging blankets can be wrapped around the exhaust system for insulation, and are usually made of glass fibre. Glass fibre lagging blankets are produced by melting a range of compounds, including calcium oxide. When combined with the chromium containing steel when exhaust temperatures reach 200°C or more, calcium chromate can be produced.
To determine risk to workers conducting exhaust rebuilds, monitoring was undertaken for each task with the purpose of determining exposures by task in addition to calculating the time-weighted average of a full shift Results in this case study indicated low full shift results, however specific tasks had the potential to expose workers to moderate airborne concentrations.
To reduce the risk of hexavalent chromium exposures in the workplace the case study recommends the following:
Preventing the occurrence of calcium chromate by using insulation that doesn’t include calcium (or another oxide such as sodium).
Make sure that exhaust components are not cleaned using power tools or dusty methods
Introduce an assessment protocol:
Is this an at-risk component? Do I need to put PPE to do the initial assessment?
Is there any yellow discolouration or powdery deposit present?
Use an initial screening tool – use a hex check colorimetric indicator kit. There are a couple of different types available, for example, a swab kit similar to a lead testing kit The indicator changes colour if there’s hexavalent chromium present.
The outcome of the above steps points to what further controls may be required.
Develop a procedure for cleaning and disposal of exhaust components.

While the LTIFR calculator provided useful insights into the relationship between poor WHS and productivity, it had limitations when used alone to measure overall WHS performance. In response, Safe Work Australia engaged in extensive consultation to explore alternative methods that enable users to more accurately assess, measure, and report on WHS performance.
EXPLORE THE NEW WHS DATA REPORTING TOOLS ON SAFE WORK AUSTRALIA’S DATA WEBSITE
Drawing on Safe Work Australia’s National Dataset for Compensation-based Statistics and ABS Census data, a new WHS profile of the nursing, care, and support workforce has been published. This profile highlights the common risks workers in these sectors face in the course of their duties. These insights can support PCBUs and workers in better understanding and managing the specific risks associated with their industry.
SafeWork SA has launched a two-year compliance campaign targeting businesses involved in lead risk work to ensure they are meeting legal obligations and protecting workers from the serious health risks associated with lead exposure. Inspectors will conduct audits and site visits in response to lead risk notifications, with enforcement action taken where non-compliance is found
The workshops are designed for managers and supervisors to build foundational skills in identifying, assessing, and managing risks to psychological health and safety. Aligned with the Mentally Healthy Workplaces Toolkit, the workshops are split into two modules: Psychological Health and Safety, which covers relevant legislation, hazard identification, and mental health promotion; and Early Intervention and Supporting Recovery, which focuses on recognising warning signs, having supportive conversations, and managing recovery in the workplace. Sessions are available both inperson in Brisbane and online via Zoom, with flexible module selection and no prerequisites. Workshops are free but have limited capacity, so early registration is encouraged.
The AIOH have partnered with GCG TechLab to offer a series of awareness courses on the fundamentals of dust, mould, and mould remediation for cleaners. All courses are 100% online.
About this course
Dust occurs naturally and from man-made activities like driving on a dirt road or sawing a piece of timber. In most workplaces, dust is considered problematic and a hazard, especially as dust can impact your health. This course is designed to give you a fundamental level of knowledge and understanding of dust. You will learn what dust is, how to identify dust and the risks associated, the negative health effects of dust, and the controls use to manage the risks associated with dust.
AIOH Mould Cleaning for Cleaners
About this course
Mould is everywhere It's a naturally occurring organism that plays an important role in nature's ecosystem
Low levels of mould can virtually be found everywhere, even in the most sterile rooms Mould may grow indoors in wet or moist areas lacking adequate ventilation, including walls/ wallpaper, ceilings, bathroom tiles, carpets, insulation material and wood
AIOH Mould Awareness
About this course
If moisture accumulates in a building mould growth will often occur. Mould affects people differently depending on their health and the type of mould. It can cause nasal and sinus congestion, hay fever, sore throats, headaches, eye irritations, body rashes and other aches and pains. Mould not only has the potential to cause health problems, but it can also cause damage to the buildings and surfaces it inhabits. AIOH's Mould Awareness online training module is designed to help learners identify mould, understand the conditions that can promote mould growth and develop an awareness of the steps for safely managing the presence of mould.
WorkSafe has laid the first charges under Victoria’s engineered stone ban, prosecuting bathroom wholesaler Fienza Pty Ltd for allegedly breaching new regulations.

SafeWork NSW is urging workplaces in flood-affected areas to prioritise safety as cleanup begins Common hazards include contaminated water, broken glass, unstable surfaces, damaged electrical systems, and potential asbestos exposure especially in buildings constructed before 1990. Workplaces should thoroughly assess risks, follow emergency service advice, and ensure workers have proper training, PPE, and rest breaks. The five-day asbestos removal notice has been waived to allow for urgent cleanup, but only licensed professionals should handle suspected asbestos. Employers must ensure all tasks are well-planned and risks controlled to protect workers' health and safety during recovery.

SafeWork SA is warning DIY home renovators to be cautious of asbestos, which remains present in thousands of South Australian homes, especially those built or renovated before the late 1980s. Even simple tasks like drilling can disturb asbestos materials and release deadly fibres. Although asbestos use was banned in Australia in 2003, removal notifications have increased significantly, with more than half from residential properties. Asbestos-related diseases cause about 4,000 deaths annually in Australia, making professional removal strongly recommended. SafeWork SA urges homeowners to avoid disturbing asbestos, use licensed removalists for safe handling,anddisposeofasbestoswasteproperlytoprotecthealthandsafety.

Occupational hygiene often takes professionals to unexpected places — from the depths of underground mines to the peaks of remote mountains. Sometimes the fascination lies in the nature of the contaminants being investigated or the scale of the work, while other times, it’s the location itself that makes the job unforgettable.
In early 2020, just as the world was beginning to grasp the implications of the COVID-19 pandemic, I was fortunate to undertake one of the most memorable assignments of my career — a rapid deployment to Antarctica to carry out asbestos inspections at two Australian research stations.
The journey began in late January aboard the Aurora Australis, embarking on its final voyage south before retirement. The mission was designed to be a tightly coordinated 15-day round trip: 11 days at sea, a short stop at Davis Station, followed by a quick inspection at Casey Station, before returning to Hobart in mid-February.
The scope of work was straightforward — an update to the asbestos registers at both stations and a post-project inspection of a removal job completed at Davis during the winter of 2018. However, "straightforward" takes on a new meaning in Antarctica. In subzero temperatures and extreme conditions, tasks that typically take an hour — such as a visual clearance — are often allocated a full day to ensure safety and accuracy.
To ensure a job is completed, as it is not an easy task to get back to site if you need additional information. This was quickly evident when onsite and discussing potential work that an Occupational Hygienist could complete whist at the Research Station, opportunistic jobs such as Indoor Air Quality or noise surveys were potential options
but accessing the right equipment was not an option. These risk assessments became a qualitative assessment and review of controls rather than the data based assessment most of us really appreciate.
As with most things during the early months of the pandemic, the best-laid plans were quickly upended. Weather conditions delayed our progress, and the evolving COVID situation added layers of complexity to the logistics. An unexpected three-day delay at sea extended my stay at Davis indefinitely, as poor weather made the flight to Casey impossible until conditions improved.
Despite the challenges, the trip was a powerful reminder of the adaptability required in occupational hygiene — and of the once-in-a-lifetime opportunities this career can provide.

In response to emerging health risks and high-profile safety incidents, significant reforms have been introduced to Australia’s work health and safety (WHS) framework. These updates reflect a growing emphasis on both traditional hazards and emerging psychosocial risks.
From 1 September 2024, amended model WHS Regulations introduced stricter controls on crystalline silica substances. These regulations mandate detailed risk assessments, air monitoring, and a silica hazard register for all workplaces handling materials with 1% or more crystalline silica. The changes aim to combat the rising cases of silicosis linked to engineered stone and similar materials.
Addressing the mental health toll of work, the Managing Psychosocial Hazards at Work Code of Practice 2024 was adopted by federal and most state regulators in November 2024, setting clear expectations around identifying and controlling stress, fatigue, bullying, and traumatic exposure. While adoption is nationwide While adoption is nationwide under the model laws, implementation timelines vary across jurisdictions.
From 1 July 2024, industrial manslaughter offences came into effect in multiple states, including South Australia. These laws impose penalties of up to 25 years' imprisonment for individuals and $18 million fines for corporations found responsible for workplace deaths due to gross negligence.
Further reinforcing health protections, amended lead regulations from March 2025 now define lead risk work using tighter blood lead level (BLL) thresholds—5 µg/dL for women of reproductive capacity and 20 µg/dL for others—prompting mandatory health monitoring and notification. Looking ahead, SafeWork NSW will be replaced by an independent WHS regulator on 1 July 2025, aimed at improving enforcement and oversight in the state.
These updates collectively signal a shift toward more proactive, enforceable, and health-focused WHS regulation across Australia, demanding increased vigilance and compliance by employers and PCBUs.

The presence of lead oxide in welding fumes is a significant occupational hygiene issue. In 2021 the Institute for Health Metrics and Evaluation (IHME) estimated that, globally, over 1.5 million deaths were attributed to lead exposure Within Australia, a study conducted on workers whose tasks involved welding found that 76% of respondents were exposed to welding fumes at a high level. If work is likely to cause the blood lead level to exceed 20μg/dL (or 5μg/dL for a female of reproductive capacity), this is classified as lead risk work under the Work Health and Safety Regulations 2022.
Lead oxide is dangerous because lead is a poisonous metal that interferes with the body’s crucial regular functions Lead can enter the body in various ways, with welding fumes containing lead oxide entering the body through inhalation, ingestion, and skin contact. Such fumes are solid airborne particles (<0.05 µm) formed by vaporisation of a solid which has been condensed by cool air Material containing lead may be invisible to the naked eye or appear as smoke or mist. Welding tasks including heating materials through an electric arc, gas welding torch, heat guns, and other heat sources can result in welding fumes. As these sources heat the material above its boiling point, this causes the solid to convert into a gas This gas then disperses through the air where it cools and converts back into a solid state in the form of tiny particles, forming lead oxide.
Common industries where lead oxide fumes may be produced through welding include automotive repairs, construction, and manufacturing, especially metal fabrication. These industries are more prone because of the increased likelihood of operating on lead materials They also use certain forms of welding that produce more fumes compared to others, including Shielded Metal Arc Welding (SMAW) (also known as stick welding), and Flux-Cored Arc Welding (FCAW). These forms of welding use consumable electrodes (welding rods), which are comprised of a metal alloy that acts as filler metal and may contain lead. However, other forms of welding are still susceptible to producing welding fumes, such as Gas Metal Arc Welding (GMAW/MIG), Gas Tungsten Arc Welding (GTAW/TIG), and oxy-fuel welding
The severity of the health consequences induced by lead is influenced by the route of entry, biological traits of the person involved, and the dose and the length of exposure
Inhalation is the main route of entry because welding fumes contain lead oxide particles Depending on their size, these particles will either deposit in the upper or lower respiratory tract. The smaller particles can bypass the body’s defences, not exiting through sneezing or coughing, and therefore reach the lungs. Within the lungs lead particles can then enter the bloodstream and spread throughout the body’s organs. Lead is also harmful via ingestion, which can occur through ingesting contaminated food, water, or cigarette matter. This route of entry is uncommon but can result in lead reaching the digestive organs Skin absorption can occur in rare cases if the skin is exposed during welding processes, or if personal protective clothing is not properly decontaminated. Lead can then make physical contact with exposed skin and be absorbed into the body.
Another factor that impacts the severity of lead poising is dosage. The dosage depends partly on the metal alloy and how much lead is being vaporised. It also depends on the duration of exposure to lead oxide. The stronger the dosage and longer the exposure period (or frequency of exposure), the greater the potential for lead to spread deeper within the respiratory system
Despite the toxic nature of lead, short-term exposure usually only results in relatively mild short-term health effects. These include irritation to affected organs, headaches, joint and muscle pain, dizziness, chest and abdominal pain. However, long-term exposure is likely to cause severe and long-term health effects. These include reproductive issues, cardiovascular issues, nerve damage, kidney damage, and deteriorating brain function such as intellectual deficiencies. In extreme cases lead poisoning can cause death. As lead oxide is suspected to be able to cause cancer of the organs including the brain, kidney, and lung, it is labelled as ‘carcinogenicity: category 2’
Lead poisoning is clearly a serious chemical hazard that must be addressed in relevant workplaces It is crucial to implement numerous risk management measures to effectively lower the risk of lead poisoning. Through the hierarchy of controls, potential workplace controls include:
If reasonably practicable, do not weld on or have any materials containing lead within the workplace;
Operate welding practices on safer metals rather than using materials containing lead; Use welding methods that produce less fumes, such as TIG welding (Gas Tungsten Arc Welding);
Physically distance welding processes from other tasks where possible;
Have a clean space for food and drink consumption where personal protective equipment (PPE) is not to be worn;
Use operational local exhaust ventilation (LEV) systems to capture fumes;
Administration:
Provide adequate training on safe work practices including hygiene and decontamination of PPE; Implement job rotations to minimise duration of exposure;
Continual monitoring and record keeping of lead levels in the air to ensure the workplace exposure standards (WES) eight-hour time weighted average of 0.05 mg/m3 is not exceeded; Personal Protective Equipment: Provide and correctly wear all required protective equipment, including long sleeved shirt, pants, gloves, shoes, and welding helmets with powered air purifying respirators (PARs); Workers should be fit-tested and clean-shaven prior to commencing tasks.
The burden of this hazard is avoidable, as appropriate implementation of various risk management controls prevents dangerous and repetitive exposure to lead Persons conducting a business or undertaking (PCBU’s) have a duty of care over their workers which requires emphasis on prevention rather than the treatment of lead-based health adversities once developed. PCBU’s and workers need to be appropriately aware and equipped for working with lead as this is crucial for their health.

Why are you passionate about OH, and what keeps you dedicated?
Being an occupational hygienist has been a privilege to have a job where I can make a difference to protect worker’s health Working with both senior managers and workers has been challenging, both technically and having the right influencing skills to make a difference It has often been long hours however it has been a lot of fun working closely with amazing people to improve the health and safety in their workplace. Being an occupational hygienist opened the door to a career working throughout Australia and internationally. Working at the biggest mine sites in the world as well as working in all aspects of the petroleum industry. From refinery workers, to aviation refuellers, to asphalt workers, to oil traders making multi-million dollar deals, there was always a health issue
Occupational hygiene has given me an opportunity to meet many inspiring people as well as making lasting friendships throughout my career. Hence I continue to support young people and the profession through my volunteer activities, especially OHTA, https://ohtatraining.org/. Istheresomethingyouwouldlikepeopletoknowaboutyouand/orOccupationalHygiene/AIOH
In my travels, I have created a collection of Georgian and Victorian door finger plates of international standing. My next goal is to establish a website to showcase the fabulous workmanship of these unknown artisans Along with the fabulous beauty of the door plates, I hope to tell their stories about working conditions and health risks.

Why are you passionate about OH, and what keeps you dedicated?
I’ve always been driven by a deep commitment to protecting worker health. Istheresomethingyouwouldlikepeopletoknowaboutyouand/orOccupationalHygiene/AIOH There’s nothing more meaningful than knowing your work helps someone make it home whole and healthy What keeps me going is the opportunity to create a lasting impact through education, leadership, and advocacy, and to influence the next generation of professionals who will carry that mission forward.
The effect of an Occupational Hygienist is a bit like the invisible hazards we work to control, only ours is a positive kind of invisible It is measured by the illnesses that never happen and the lost-time injuries that never occur, and although we may never fully quantify the extent of what we prevent, we know our work makes a real difference. And yes, we all get a little too excited about new equipment, spreadsheets, and good data. It’s all part of the magic!

Why are you passionate about OH, and what keeps you dedicated?
I am passionate about improving workers health outcomes so that workplaces as safe and health places to be Improved worker health improves lives for all
Istheresomethingyouwouldlikepeopletoknowaboutyouand/orOccupationalHygiene/AIOH
Occupational Hygiene is a professional focussed on improving the health of all It is a great career if you like working with people and are happy to have a work life that is constantly changing You also need to have a passion for continue to learn and grow in your know of occupational health.
What is your role in the committee, and how did you get here?
I have represented the University of Wollongong on PD&E for the last 16 years.
WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
After working in industry for over 25 years, seeing countless cases of illness that should never have occurred and striving to improve occupational health outcomes, I realised I was doing the same things, just in different places
Joining UOW enables me to have a much greater impact and to touch the future by equipping today’s occupational hygienists.

Working across many organisations, there is always a strong focus on prevention of acute, physical injuries. The support and resourcing for prevention of chronic and latent occupational illness has traditionally been limited as the outcomes are not immediately visible. My passion is supporting better health outcomes for the workforce

What is your role in the committee, and how did you get here?
I am an active member of the PD&E Committee, contributing to several key projects such as reviewing chapters for the Principles of Occupational Health and Hygiene and the AIOH Report Writing Guidelines among others. I joined the committee as a representative and Program Manager of the Master of Occupational Health and Safety (Occupational Hygiene Stream) program at RMIT University, Melbourne
WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
With over 25 years of experience in high-risk industries, I’ve witnessed firsthand the painful effects of occupational hazards on workers. These frontline encounters have shaped a deep sense of empathy and a strong desire to make a difference My passion for occupational hygiene is driven by the urgent need to protect workers, and what motivates me daily is the awareness of the serious consequences that can result from inaction in reducing workplace exposures.

I am an industry representative member of the PD&E committee who is passionate about continual growth and learning in our industry I became a committee member to support the Institute and help our members who are facing new and dynamic workplace challenges.
WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
Fundamentally I believe no person should suffer any ill health effects as a result of simply going to work and I will continue advocating for worker health wherever I can.

What is your role in the committee, and how did you get here?
II’m part of the PD&E Committee, where I help shape the professional development and education programs we offer at the AIOH. I ended up here thanks to a mix of saying “yes” to opportunities, a genuine love of learning, and a strong belief in giving back to the profession. I’ve always been passionate about helping others grow and develop, so this committee felt like a natural fit
WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
Occupational hygiene brings together everything I love: science, problem-solving, and most importantly, people I’m especially passionate about education and research, and I find it incredibly fulfilling to support students as they grow into confident, capable professionals. Watching them develop their skills, challenge ideas, and go on to have rewarding careers in OH is one of the best parts of what I do. That, and knowing that our work really can make workplaces healthier, happier places.

What is your role in the committee, and how did you get here?
I’m one of three facilitators for the Basic Principles of Occupational Hygiene (BPC) course. I’ve been involved in delivering these courses for many years my first one was way back in 2008! In 2021, I was fortunate to step into a more permanent role alongside the fabulous Linda Apthorpe, and more recently, Melanie Cox joined us last year
I love being part of the Basic Principles of Occupational Hygiene (BPC) course. We get such a wide variety of people coming through, from those who’ve only just heard the term “occupational hygiene,” to others who have been working in the field for some time, often in a specific area like hazmat, and now want to broaden their understanding. We also see doctors preparing for occupational physician exams who need a solid foundation in the principles The energy in the room is always high, even though the course is intense, it’s five days of content that can feel like drinking from a fire hose! But it often whets their appetite, and it’s incredibly rewarding to see so many go on to further study in the field.
More broadly, occupational hygiene has such a tangible impact,it’s about protecting people’s health at work and preventing harm before it happens That proactive, evidence-based approach really resonates with me We’re helping to create healthier workplaces, prevent illness and injury, and educate people,many of whom are genuinely interested in how they can make a difference. That sense of purpose, and knowing our work can improve someone’s long-term health and wellbeing, is what keeps me inspired and dedicated.

I’m one of the AIOH Basic Principles of Occupational Hygiene Course facilitators I’ve been teaching this AIOH course for over 15 years The course sits under the remit of PD&E
WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
I love sharing my passion for occupational hygiene and how to protect worker health during teaching and training opportunities, including facilitating the AIOH BPC
Learning is a lifelong adventure, and I’m honoured to be a BPC facilitator and to have the chance to grow and learn more by teaching the course, meeting new people and learning from our wonderful students in diverse workplaces who want to know more about occupational hygiene!

WhyareyoupassionateaboutOH,andwhatkeepsyoudedicated?
The basic premise that everyone deserves to come home to their families without illness or injury is the reason I remain passionate about occupational hygiene.

We kicked off our first NSW SLOW meeting in 2025 with a ‘lunch and learn. Paul R Pickering (Aeroqual) and James Thompson (EP Risk) provided insightful case studies on managing contaminants at legacy industrial sites and how real time monitoring was a valuable tool in monitoring controls and quick decision making. A big thank you to for our guest speakers sharing their expertise on a wide variety of contaminants such as arsenic, lead, PAHs, VOCs, diesel particulate, crystalline silica, and noxious gases including CO, NO₂, and H₂S.
The session highlighted the importance of utilising multiple monitoring strategies— whether personal, static, or handheld—to assist with compliance requirements and site-specific risks. A key message was the value of real-time data to support fast, informed decision-making in dynamic work environments.
Special thanks to Richard Wilkinson (Tetra Tech) for hosting and Jason Foster (ETS) for sponsoring the speakers.

If you have a presentation idea or an experience to share, we encourage you to get involved. These meetings rely on collaboration, and your insights can provide valuable takeaways for others.
Thank you to our state liaisons for providing a space where professionals can exchange knowledge and build connections. We look forward to hearing from more members and seeing new contributions to our Chapter Meetings.

The Australian Institute of Occupational Hygienists (AIOH) is conducting an important survey to evaluate workplace health performance. We’re seeking insights to help define good health practices, identify gaps in occupational health management, and establish a framework to improve worker health outcomes.
What will the survey achieve?
Define what constitutes good health in the workplace
Identify gaps in occupational health management
Establish a baseline for continuous improvement
Provide a framework for safeguarding worker health
Participation in the survey is voluntary and anonymous.
We expect that the survey will take 15 minutes to complete. Your input will help shape the future of worker health.

We’re thrilled to announce that registrations for AIOH25 have officially opened!
In 2025, we are embracing the theme of 'Evolution, Insights, Into Impacts' a concept at the heart of our profession as occupational hygienists, in the beautiful city of Sydney, New South Wales
Since AIOH21, our themes - Challenge for Change, Simple Sustainable Solutions, Future Ready, and Scientific Storytelling - have all pointed to one word: Evolution AIOH25 explores the ongoing evolution of occupational hygiene and the challenges shaping our industry
Post 2020, changes have placed occupational hygienists in greater demand than ever Driven by legislative updates, technological advances, rising workplace expectations, and a world-class commitment to progress, it's an exciting time for our profession. But key questions remain: Have we done enough? Are we truly future-ready? Are we guiding the next generation? What insights can we provide to make meaningful impacts?
AIOH25 will explore:
The next generation of occupational hygienists - how we promote, train, and inspire
Insights, the changes in legislation and what impact it is having
New sampling methodologies and cutting-edge technologies
How we continue to anticipate, recognise, evaluate, and control
And most importantly: Are we there yet, or is there still more to do?

Following the success of last year’s members’ debate, we are excited to announce preparations for this year’s debate are underway!
We are now seeking Expressions of Interest from those who would like to be involved as Team Captains or Debate Participants The debate aims to showcase diverse perspectives on key issues that shape our profession and provide an engaging, thought-provoking session at the upcoming conference
This year’s format will again feature two teams, each consisting of three members, including a Team Captain, debating on a topical occupational hygiene theme The session will be facilitated by a neutral moderator, and audience voting will determine the winning team.
We are currently considering a range of debate topics that reflect both emerging and ongoing challenges in occupational hygiene, including:
The potential of AI and automation to enhance or hinder hygiene practice
The need to shift focus from exposure control to health outcomes
Whether universal exposure standards are appropriate across industries
The practical limitations faced by SMEs in adopting best-practice controls
And whether it’s time to rethink the traditional hierarchy of control
These are just some of the possible topics under consideration the final debate theme will be selected based on relevance, balance of perspectives, and participant interest
If you’re interested in taking part whether to lead, debate, or contribute, please let us know by submitting your EOI.

As 2025 gathers momentum, the first three BPC courses have been presented in Melbourne (March), Sydney (April-May) and Perth (May), with all participants successfully completing the OHTA201 certification. Congratulations to all who attended!
Do you know that the AIOH BPC has a long history?
First held in 1985, the original concept was a two-day crash course conceived and written by Brian Davies and Doug Rhodes - and presented to a class of two students! From there, the course grew to a 4-day course with practicals and an exam Around 2012 the AIOH became accredited with the OHTA (International Occupational Hygiene Training Association), and now the current BPC course merges the original practical AIOH content with the OHTA201 course to provide that ‘AIOH extra’!
To celebrate the 40 years that the AIOH has been providing practical training for OHs, we will be bringing you some words from some of our alumni - both recent and from across the decades. They’ll be sharing some of their thoughts and memories of the AIOH BPC and how it ignited that special spark to begin a career in occupational hygiene and set them on their pathway to their current careers.
Alumni Interview
Mark Reggers (COH, MAIOH) who attended the BPC in Sydney 2010/2011
What is your current Job Title?
Occupational Hygienist/Specialist Application Engineer
Why did you sign up for the BPC?
At the time I was working in a PPE & safety technical sales role, so I attended this course to improve my knowledge to better assist support my customers Also to know when to refer a customer to an Occupational Hygienist
Did the BPC influence your decision to enter or remain in the OH field?
Absolutely. I really enjoyed the course and found it so interesting. This is what then lead to me enrolling into the Occupational Hygiene Graduate Certificate Program at Uni of Wollongong. It was then at UOW I decided to pursue a career in Occupational Hygiene, so without the BPC and exposure to Occ Hygiene I would not be in the profession I am today!
Would you recommend the course to future Occupational Hygienists?
No doubt about it We all don’t know what we don’t know The BPC does an amazing job of exposing attendees to an inkling of the breadth of OH and there are so many areas that people can focus on, thinking of work/career engagement/satisfaction. This is on top of the genuine drive and passion to protect workers' health which is a worthy endeavour itself. Then you have the most amazing network and connections of Occupational Hygienists Plus, the conference The fun never ends in Occupational Hygiene ��
Thank you Mark for telling us your story!
We would love to hear your story, too! If you have completed the AIOH BPC and would like to share your experience or memories, please contact Claire Phypers at office@aioh.org.au

Isabel Kotzee - Dual Masters of Occupational Hygiene / Occupational Health and Safety at The University of Queensland
Comparative Analysis of DPM Sampling Techniques:
Measuring Respirable Elemental Carbon vs Submicron Elemental Carbon in an Underground Coal Mine
Isabel Kotzee is new to the world of Occupational Hygiene – after finishing school, she thought she
wanted to do medicine as she loved biology, science and wanted to make a tangible difference in people’s lives. Thus, she pursued the Biomedical Science pathway at The University of Queensland in 2020 After completing obtaining her bachelor’s she realised that medicine was not the right fit and discovered occupational hygiene! She enrolled in a dual Masters of Occupational Hygiene / Occupational Health and Safety at The University of Queensland.
With GCG’s support Isabel conducted her research project on a Comparative Analysis of DPM Sampling Techniques in an underground coal mine in Central Queensland
Isabel is a student member of the AIOH with the intention of applying for Associate soon.
The current recommended workplace exposure standard (WES) in Queensland for DPM is 0.1mg/m3, based on the submicron size fraction (<1 μm). However, at the time Safe Work Australia had proposed a new WES for DPM measured in terms of REC (5μg REC/m3). Several questions were posed with regards to surrogate measurement techniques for DPM; would using a GS-3 Respirable Dust Cyclone with respirable elemental carbon (REC) analysis lead to higher concentrations of REC as a replacement for measuring DPM concentrations? Does using a DPM Plastic Cyclone with submicron elemental carbon (SEC) analysis, impact the amount of interference from coal mine dust on the inferred concentration of DPM? What potential insights could these findings provide for the Queensland Mining Inspector (QMI) with regards to the proposed new REC WES for DPM?
In response, area sampling was conducted in an underground coal mine located in the Central Queensland Bowen Basin region of Australia. Sampling consisted of utilising a GS-3 Respirable Dust Cyclone with REC analysis and sampling using a DPM Plastic Cyclone with SEC analysis, as a surrogate for measuring DPM concentrations Sampling was undertaken on two development panels (Panel 601 and 602).
Three different locations were sampled at each panel. Overall, the results demonstrated that SEC concentrations were consistently lower than REC concentrations, irrespective of the location. Potential interference from coal dust and other carbonates was identified, as the presence of coal dust can artificially elevate the carbon measurement that is attributed to DPM.
Therefore, the proposed change in REC WES for DPM would present significant limitations in measuring and regulating DPM in underground coal mines, where interferences can occur. This suggests that the submicron sampling method using an impactor should be utilised in an underground coal mine environment to avoid this. However, DPM and dust have been found to agglomerate together, meaning that this method may miss supra-micron DPM, therefore, additional research is required. This should include multiple mines, thus increasing the sample size to enhance the reliability of the results due to potential variations that exist between mines

levels of the organisation A lack of a robust communication network can lead to failures in sharing important information, with potentially devastating consequences for individuals and workers (Cameron, 2024).
When managing chemicals, health and safety practitioners heavily rely on information provided by manufacturers or suppliers. This information outlines the dangers of handling, storing, and transporting hazardous substances, as well as the necessary safety precautions workers should take to protect themselves and others. It also includes procedures to follow in the event of a spill, exposure, or fire. However, the hazard communication tool known as the Safety Data Sheet (SDS) has often been criticized as a flawed document. The predecessor to the SDS, the Material Safety Data Sheet (MSDS), faced significant scrutiny regarding its accuracy, readability, and comprehensibility (Eastlake , et al., 2011; Hodson et al , 2019; Eastlake et al , 2012; LeBouf et al , 2018; Phillips et al , 1999)
Medical professionals have raised concerns about whether the MSDS effectively conveys the medical consequences of chemical exposure (Bernstein, 2002; Greenberg et al., 1996). Many stakeholders including those working with chemicals, providing expert advice, and regulatory bodies hoped that the introduction of the Globally Harmonized System for the Classification and Labelling of Hazardous Chemicals (GHS) would ensure consistency in chemical classification, improve readability, and eliminate vague language in favour of a more straightforward approach. Eight years after the adoption and implementation of the GHS in Australia, the question remains: Are workers and health and safety professionals better equipped to communicate the hazards associated with handling hazardous chemicals and dangerous goods?
Research conducted as part of a PhD program found that, despite efforts to harmonise both the structure of the SDS and the classification of hazardous chemicals, it has fallen short in certain respects, particularly regarding content and context. To grasp the significance of the SDS, it is important to recognize that it is not only a legally required document detailing scientific information but also a valuable resource for workers handling chemicals throughout their lifecycles. Emergency services personnel and first responders require clear communication regarding hazards and emergency responses before addressing a worker's needs, managing a chemical spill, or extinguishing a fire.
Although the SDS is often authored by chemists, toxicologists, or safety professionals, numerous companies are now developing software programs to assist in creating customized Safety Data Sheet documents. Using a common chemical substance such as liquid nitrogen highlights the challenges faced by workers and health and safety professionals. In Australia, there are only a few producers of liquid nitrogen; therefore, minimal variation between suppliers might be expected. However, this was not the case.
While health and safety professionals are generally familiar with several well-known physical properties of nitrogen in its liquid state, some basic information appears to have been overlooked in favour of more detailed and complex information that is often irrelevant in workplaces "Red flags" emerged in the form of non-GHS precautionary statements, irrelevant first aid advice related to exposure to liquefied petroleum gas, multiple references to compressed nitrogen and gas cylinders, and a 20-degree Celsius discrepancy in the recommended ambient storage temperature for portable liquid nitrogen containers These discrepancies suggest that those authoring the SDS may not fully understand how misinformation can impact the ability to conduct an informed risk assessment. Statements such as "consideration should be given to the possibility that overexposure to materials other than this product may have occurred; try to stop release; stop the flow of gas if safe to do so while continuing cooling water spray; or avoid heat, sparks, open flames, and other ignition sources" can lead workers to several potential actions that may jeopardise their health.
In many cases, the SDS is written by production chemists, toxicologists, or safety professionals; however, many companies offer self-authoring software to facilitate this process. With the rise of AI technology in both our personal and professional lives, questions arise regarding the accuracy of AIgenerated safety data sheets
At this juncture of the research project, it is clear that misleading and/or inaccurate SDSs impact the ability of workers to undertake an informed risk assessment. One of the biggest challenges is countering misinformation and correcting erroneous information. WHS regulators often cite the SDS as being a key resource in the development of risk assessments and the management of chemicals in the workplace. How does the safety professional credibly counter the misinformation.

If you are going to EXPO 2025 in Osaka, Japan the IOHA will be presenting and exhibiting as part of the Global Initiative for Safety, Health, and Wellbeing. The presentations will focus on the future of work and the challenges and opportunities of occupational hygiene in advancing worker health into the future
Jan-Mar 2025 edition Global Exposure Manager (GEM) has been released with articles considering the Expanding Role of Occupational Hygienists in a Changing World of Work which considers the how social and financial expectations of companies in relation to the human sustainability of the work they conduct An article on control banding provides an informative overview of the topic specifically in relation to the management of chemical risks For some fun and creativity there is a piece on the Occupational Hygiene Chronicles a comic strip which is a great awareness communication piece on hygiene in the workplace and wider society.
The BOHS has been involved in a number of initiatives and outreach since late 2024 to 2025. The BOHS has been involved in a report on women’s workplace health “The UK’s Hidden Crisis in Women’s Workplace Health” The BOHS asserts through the report that women are unfortunately having higher rates of long-term sickness, worse health outcomes in most exposure categories including MusculoSkeletal Disorders (MSDs) and mental health. It also notes the UK Health Safety Executives (HSE) highest predicted cancer is breast cancer is associated with night shift work and includes other negative health issues such as premature menopause and miscarriage. A significant barrier for women is raising health concerns at work, due to the uncomfortable and personal nature of these health concerns
The BOHS is preparing for OH2025 The Workplace Health Protection Conference will be in Newcastle UK (June 16-19) will focus on innovation in workplace health.
The AIHA continues to advocate for the reinstation of the full functionality of the National Institute for Occupational Safety and Health (NIOSH) with a nationwide campaign in the USA.
In April the AIHA released the 2025 update to it Grand Challenges for Worker Health, Safety, and Well-being. The Grand Challenges identify challenges in the field of worker health, safety, and well-being which if accomplished would significantly reduce occupational injuries, illnesses, and fatalities and improve workers’ quality of life. Four challenges were decided as areas which filled this purpose:
The Changing Work Environment
Promoting Health Equity and Eliminating Precarity in the Workplace
Improving Exposure Assessment
These challenges were approved by the AIHA Board of Directors in February 2025 after four years of development of the Grand Challenges project and now looks at the next steps of addressing these challenges.

We are in challenging times. Times that require our resolve to stay the course on behalf of the people we serve and identify and implement innovative solutions. Times that require growth and change in occupational health and hygiene. Why? Our current strategies, systems, models, and approaches are not working. Around the globe and locally, we are not effectively preventing chronic non-communicable occupational disease. We need to do things differently. The time is upon us for innovation including new ways of thinking. What does innovation in occupational health and hygiene look like? It includes integrated, holistic approaches, impactful partnerships, it is silo free, it is meaningful investment in workers, families, and communities – investment in prevention and wellbeing, and it is aligned with efforts in social sustainability and the United Nations Sustainable Development Goals and other important strategies to future proof our world and its people– such that we leave no one behind. Together, let’s drive change in occupational health and hygiene.
