SRCMC Welcome to the July edition of The Filter.

As we move through another busy and productive year for occupational hygiene, this issue highlights the strength, expertise and commitment of our AIOH community. From scientific research and professional development to member achievements and industry updates, this edition showcases the many ways our profession continues to advance and influence healthier workplaces across Australia and beyond.

A highlight of this issue is a glimpse inside the 2026 AIOH Annual Scientific Conference & Exhibition, highlighting the insights, innovations and connections that continue to shape our profession.

The AIOH Members Hub celebrates the people who make our Institute thrive. We welcome new members, recognise certification achievements and milestones, and pay tribute to the late Dr Barry Chesson AM. Professional growth remains central to our mission, with updates on certification, training opportunities, webinars and educational pathways.

The feature article, Why 3D Printing Needs Better Exposure Control, explores an important topic for practitioners working to identify, assess and control exposures in all environments. Alongside this, readers will find research highlights, industry updates and award-winning contributions that demonstrate the depth and breadth of occupational hygiene practice.

On behalf of the Editorial Team, thank you to all contributors, volunteers, authors and members who continue to support The Filter and the broader occupational hygiene profession. Your expertise, enthusiasm and dedication are what make our community so vibrant.

I hope you enjoy this edition and find inspiration, knowledge and practical insights that support your professional journey.

Kind regards,

Kelly Jaunzems

The AIOH Comms and Marketing Update Community Hamish Rae - Marketing and Communications Sub-Committee Lead

Well, it’s been a reasonably busy start to the year but mostly behind the scenes! After the Beyond45 transition we were happy to welcome back most of our existing subcommittee members so thankyou for all that you do and for volunteering your time to: Andrea Holloway David Macgill, Alex Britton, Sarah Verry, and Georgia Csorba.

We also took the chance after the Beyond45 transition to take a step back and refocus on what projects and goals we wanted to accomplish over the next few years.

So, as a sneak peek, here’s a few details of what we are working on and planning: Continue to put out a good product in the AIOH newsletter “The Filter” but also look for ways to evolve it so to provide more content that is engaging and interesting to our members. If you have ideas or suggestions – we want to hear from you!

Look at what the AIOH creates and shares through it’s social media accounts, with a potential look to increasing the amount of more technically-focussed content shared. We are looking at this in consultation with our other technical committees, but we want to ensure that we are positioning the AIOH as the trusted technical experts in the field.

We are looking at how we market the profession to people outside of it, as well as the next generation of hygienists. This includes looking at trying to develop more engaging short-form content in video formats and similar, as well as looking at how we approach students and make them aware the occupational hygiene is a great career to get into!

Investigating expanding some key events such as the Safe Work Month Breakfast Series, to look at putting on specific, in-person state-based events during Safe Work Month to give occupational hygiene a platform in a period of time when health and safety is in focus.

Finally, we have an exciting idea in the works which will be a competition for everyone in the institute to get involved in, so stay tuned for the announcement of that one soon!

As all committees are, we are doing this for the broader membership, so if you have ideas, or content or just want to get involved, please, reach out and have a chat with me through the marcomms@aioh.org.au email address.

All ideas are very welcome and we would love to hear from people about what they want to see. Until next time!

Unpopular‌ Unpopular Opinion Opinion‌

What's in a Name? (Survey Response)

Back in 2025 The Filter launched a new section called Unpopular Opinion, and there was really only one topic I wanted to kick things off with: that old chestnut that just won't go away does "Occupational Hygienist" actually describe what we do, and does anyone outside our profession have a clue what it means?

Some of you will remember the short piece I wrote on it.

Whilst only about 85 members out of our ~1,700-strong membership responded, so let's not pretend this was a rigorous poll, the result wasn't even close: 84% said it's time to have a real conversation about changing our title. I was expecting something more like a coin flip. Instead, it was closer to a landslide.

Small sample, big signal. Maybe it's the newer, early-career members coming through with fresh eyes. Maybe it's the fact that more of us are out there talking directly to industry and the public than ever before. Either way, something's shifted.

Here's the thing, though. We've spent the better part of four decades building our profile as a profession. COVID gave us a huge, if slightly ironic, boos, suddenly everyone wanted to know what an occupational hygienist thought about masks and respirators. Great exposure (pun intended). But is that really the headline we want people to remember us for?

I'd say no.

What we actually do is much bigger than that. We're the ones who find, assess and control the hazards in a workplace before they turn into someone's illness. That's the job, in a sentence.

But try explaining that at a barbecue. Try to tell someone what we do and nine times out of ten you get, "Oh, so you test stuff?" Sure, monitoring and exposure assessment are a big part of the toolkit. But they're tools, not the point.

Collecting data isn't the job, using it to stop people getting sick is.

And that's exactly why this isn't a simple fix. We've worked hard to earn credibility with regulators, government, employers and industry under the banner we already have. Rip up the name overnight and we risk ripping up a chunk of that trust and recognition along with it. That would be a genuinely bad trade.

The real problem isn't that our profile hasn't grown it has, but it’s within our own circles. The issue is that the general public is still largely none the wiser about what we do day to day.

So maybe the fix, at least for now, isn't a new name. It's a better answer to "what do you do?"

Next time someone asks, instead of just saying "I'm an occupational hygienist" and watching their eyes glaze over, try adding a line like: ● "I use science to protect workers' health finding and controlling workplace hazards before they cause harm." ● "I help make sure people go home from work as healthy as they arrived, by spotting and managing the things that could hurt them."

If people understand what we do, they'll understand who we are, no rebrand required, at least not yet.

Will we eventually land on a new name? Possibly. But if we do, it needs to be the finish line of a carefully planned, long-term strategy not a knee-jerk starting point.

For now, our biggest opportunity is simply to keep telling people, consistently and clearly, what value we bring: We protect workers' health. Get that message to stick, and any future conversation about our name becomes a whole lot easier.

P.S. Still don’t like the name!

Tuesday 1st December 9:15am - 10:15am

Occupational hygienists work in a world where complex and often invisible risks need to be understood by very different people - workers, leaders, regulators, clients and stakeholders. And in those moments, communication becomes just as important as technical knowledge.

As scientists, we learn early on that technical expertise and achievement is what builds a career. What we've failed to convey is that the greatest measure of career success is in the impact and influence we have on others. Most occupational hygienists spend years developing skills in exposure assessment, toxicology, epidemiology, and biostatistics yet they receive little or no formal education in leading people, influencing change, or building highperforming teams.

Most of the 3D printers in schools and homes use thermoplastic filaments like Polylactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) to create solid objects. PLA is often seen as the lower-risk option for general use, especially compared with ABS, as it releases fewer fumes and particles, but that does not mean it is risk-free. The heating filament can still release fumes that may irritate the eyes, skin, nose, and lungs. For some people, especially in poorly ventilated spaces, that may also mean headaches or nausea.

The risk also does not stop when printing ends. Post-processing tasks, such as sanding, scraping, trimming, or polishing a printed object, can release fine dust and keep exposure going after the machine has stopped.

VOCs and resin printing The use of 3D printers can affect the air quality of indoor spaces. The amount and type of emissions of VOCs vary depending on the filament, the printer settings, the temperature, how long the printer runs, and how well the room is ventilated. However, VOCs such as aldehydes, hydrocarbons, aromatics and siloxanes can be released when filaments are heated, cured, or handled in a small room, and can accumulate and reduce indoor air quality.

The more important question is how much of the harmful volatile compound is being released into the air, for how long, and in what kind of space.

Resin printing adds another layer of concern. Resins look much cleaner and more advanced because it produces smooth and detailed objects. But that appearance can be misleading. Resin printing uses liquid resin that hardens under UV light. Some of these resins contain methacrylates, chemicals that can irritate the skin or make a person more likely to develop an allergic skin reaction over time. There is also usually more chemical handling involved. Printed objects often need to be washed, commonly in isopropanol, before they are cured under UV light. That means the exposure risk is not only from the printer itself. It also comes from the cleaning, washing, and curing stages.

This is why resin printing should be treated more like chemical work than a clean hobby activity. It should not be seen as a safer version of plastic printing just because the finished item looks polished.

Distance, ventilation, filtration, and careful handling all matter.

The other risks people forget Air quality is only part of the picture. 3D printers can create physical hazards because they generate heat, contain moving parts, and use electrical components. Hot nozzles, extruders, or build platforms can burn users, while moving parts can pinch or injure people if the printer is used carelessly.

YOUNG LEADERS ACADEMY

AIOH Young Leaders Academy The Australian Institute of Occupational Hygienists is pleased to announce the launch of the AIOH Young Leaders Academy (AYLA). A new initiative designed to support and develop the next generation of leaders within the occupational hygiene profession.

The ability to influence decisions, communicate risk clearly, and contribute to organisational outcomes is becoming essential. AYLA has been developed to address this need, equipping participants with the leadership capability to complement their technical expertise.

As the profession continues to evolve, occupational hygienists are increasingly required to do more than provide technical advice.

Strong leadership strengthens both individual careers and the long-term impact of the profession.

A Program Built on Proven Foundations AYLA draws on the success of internationally recognised leadership programs, including those delivered through AIHA and IOHA. These initiatives have demonstrated that early investment in leadership capability strengthens both individual career pathways and the long-term impact of the profession.

Tailored for the Australian context, AYLA brings together technical excellence, practical leadership skills, and real-world application.

What to Expect

Who Should Apply

The inaugural Academy will be delivered as a 2.5-day intensive program in Brisbane, immediately prior to the 2026 AIOH Conference.

AYLA is designed for emerging and midcareer professionals who are 40 or under that demonstrate leadership potential and a commitment to advancing occupational hygiene practice.

Understanding your personal leadership style and influence Leading teams and navigating complex workplace challenges Translating occupational hygiene expertise into organisational value Contributing to the future direction of the profession

More Than a Course AYLA is not simply a training program - it is an investment in the future of the profession. Participants will leave with practical leadership tools, increased confidence in influencing outcomes, and a strong professional network across the AIOH community.

Be part of shaping the future of occupational hygiene.

Apply Now Join a cohort of emerging leaders, develop your leadership capability, expand your network, and help shape the future of occupational hygiene

New Guidance Alert!

Safe Work Australia has published new best-practice guidance on air monitoring and the workplace exposure limits to support the transition to the new WELs from 1 December 2026.

The existing Guidance on the interpretation of Workplace exposure standards for airborne contaminants will be replaced by two new documents providing practical, targeted information for specific audiences with very different needs: Technical guide: Air monitoring and the workplace exposure limits for airborne contaminants Guide for PCBUs: Air monitoring and the workplace exposure limits for airborne contaminants The technical guidance has been developed specifically to support the work of occupational hygienists and was drafted by technical experts in consultation with the AIOH, regulators and occupational hygienists from around Australia.

As well as comprehensive information on planning and conducting air monitoring and interpreting results, this guidance also covers a range of challenging areas of occupational hygiene practice, such as use of real-time monitors, assessing exposure to mixtures, and consideration of RPE in compliance assessment. This guidance will assist occupational hygienists to use air monitoring effectively to protect and improve worker health and safety.

A Tribute

to Dr Barry Chesson AM

A Life of Quiet Influence, Lasting Impact, and Generous Mentorship.

We celebrate the life and legacy of Dr Barry Chesson AM, a remarkable leader, mentor, and lifelong contributor to occupational hygiene and the broader community.

Barry may have been modest in stature, but his presence in the profession, and in the lives of so many people, was anything but small. He was steady, thoughtful, and quietly influential in a way that shaped people and systems over decades. For those who knew him, his impact was not only professional, but deeply personal.

Laurie Glossop, a colleague of Barry's for 45 years and a close friend of Barry and Theresa for more than a decade, reflected on a man whose technical expertise was matched only by his generosity, patience, and unwavering focus on people.

Barry’s academic and professional achievements were exceptional. He held a Master of Applied Science in Occupational Health and Industrial Hygiene and a Doctor of Philosophy in Chemical Safety. He was a Certified Occupational Hygienist with the Australian Institute of Occupational Hygienists, and a Certified Industrial Hygienist (retired) with the American Board of Industrial Hygiene.

His contribution was formally recognised across many decades. He was a Fellow of the AIOH, recipient of the Celebration of Achievement Award, inducted into the inaugural AIOH Hall of Fame, and awarded the Pam de Silva Medal, the Institute’s highest honour. In 2016, he was appointed a Member of the Order of Australia for his significant service to occupational health science, professional associations, and education.

Across more than 50 years, Barry worked with Alcoa, Chevron, and later through his consultancy Occupational Hygiene Solutions.

A Tribute

His work extended across Australia and internationally, contributing to occupational hygiene programs in a wide range of industries and countries. He had a particular passion for noise control and hearing conservation, always focused on practical solutions that made a real difference in workplaces.

Laurie Glossop, a long-time colleague and friend, captured something fundamental about Barry: “Barry may have been modest in height, but he was a giant of a man in many ways.”

That sense of steadiness carried through everything he did. Whether working in industry, advising government, or supporting professional bodies, Barry brought calm, clarity, and a consistent focus on what would genuinely improve worker health and safety.

He played a significant role in shaping occupational hygiene in Western Australia, including more than two decades as an Expert Member of the WA Commission for Occupational Safety and Health. He often reflected on the importance of collaboration in this work: “It was a privilege to be present as that approach matured into what we see today.”

Within the Australian Institute of Occupational Hygienists, Barry was a founding member and one of the defining contributors to its development. He joined in 1980, became a Fellow in 2004, and went on to serve as Councillor, President Elect, and President in 2012. He also supported the Institute through committee leadership and his long-standing role as WA State Liaison Officer, where his encouragement and quiet persistence helped strengthen the profession in Western Australia.

But it is not his titles or positions that people speak about most. They speak about how he made people feel.

Tracey Bence captured this in a way that many in the profession will recognise “Barry was both mentor and sponsor for so many of us. He opened eyes and he opened doors.” She also described him as: “Legendary in the Western Australian hygiene community.”

Daniel Cronje shared a similar reflection, grounded in personal experience: “He didn’t just provide advice, he saw the potential in me.”

And perhaps most simply, but most powerfully: “Barry was quick with a smile, genuinely caring, and always wanting the best for you.”

These are not descriptions of a formal leader alone. They are the reflections of someone who consistently invested in people, often early in their careers, and continued that support quietly and without expectation of recognition.

Barry had a way of noticing people before they had fully noticed themselves.

Barry also believed strongly in developing future leaders within the profession. He often encouraged people to step forward when they saw a gap in leadership, reminding them that leadership was not about having all the answers, but about being willing to contribute and learn. Many occupational hygienists can recall being personally encouraged by Barry to take on committee roles, volunteer positions, or leadership opportunities they may not have otherwise considered. His confidence in others often came before they had confidence in themselves, and many later reflected that accepting those challenges helped them grow professionally and become better occupational hygienists.

He was also deeply committed to education As an Adjunct Associate Professor at Edith Cowan University, Barry taught and mentored generations of occupational hygienists.

He took genuine pride in seeing former students grow into senior roles, often reflecting: “To know that you may have sparked an interest in our profession at an earlier point is very rewarding.”

Dr Kelly Johnstone, President of the AIOH, reflected on his legacy: “Barry was a remarkable leader, mentor, and lifelong contributor who shared knowledge generously and fostered the next generation of occupational hygienists.”

A legacy carried forward through mentoring.It is perhaps in his role as a mentor that Barry’s influence is most enduringly felt.

The AIOH has acknowledged this legacy through the establishment of the Dr Barry Chesson AM Mentoring Award, a perpetual Council award recognising excellence in mentoring young and emerging occupational hygienists.

This recognition reflects what so many already knew, that Barry’s greatest contribution was not only in the systems he helped build or the roles he held, but in the way he invested in people. He gave his time generously, offered practical guidance without hesitation, and consistently encouraged others to grow into their potential.

For many, he was the person who quietly opened a door at just the right time, or offered reassurance when it mattered most.

Beyond his professional life, Barry’s influence extended into community and sport. He was a founding figure and inaugural President of the Murdoch University Melville Cricket Club, serving for eighteen years. He was a captain, organiser, and mentor, and for many, a steady guiding presence whose influence shaped both culture and character within the club.

His legacy there is not only in trophies or records, but in the standards he set, the people he supported, and the example he lived.

Earlier this year, we were fortunate to record conversations with Barry, Tracey Bence, and Laurie Glossop at the Chesson home. In those discussions, what stood out was not only reflection on achievement, but a consistent focus on people, on relationships, and on the importance of giving others opportunity. Those recordings now carry even greater meaning.

At the heart of Barry’s career was a simple but powerful belief, that the greatest value of his work was not in technical achievement alone, but in the people who grew through it.

He often spoke, and demonstrated through action, that success was measured in the success of others.

There is a phrase that has been shared across the profession in recent days: “Go and find yourself a Barry Chesson.”

It speaks not only to admiration, but to a standard, a way of leading, mentoring, and showing up for others that is increasingly rare, and deeply valued.

Barry, leaves behind a legacy that is both professional and deeply human. He shaped systems, strengthened a profession, and influenced practice across decades. But more than that, he shaped people.

He will be deeply missed by his family, friends, colleagues, and the many across occupational hygiene whose careers and confidence were shaped by his guidance.

His influence continues in the people he mentored, the standards he set, and the quiet example he lived every day.

Thank you, Barry.

Occupational Hygiene in the Mining & Mineral Processing Industries Course (OHTA1001)

Earlier this year, AIOH proudly delivered the first Occupational Hygiene in the Mining & Mineral Processing Industries Course (OHTA1001) in Brisbane, marking an exciting milestone in the expansion of our professional development program.

The five-day course was developed for occupational hygienists and suitably qualified occupational hygiene technicians looking to build on their foundational knowledge and develop specialist skills relevant to the mining and mineral processing industries.

Meet the course facilitators This course is facilitated by Dr Ross Di Corleto (Monitor Consulting Services) and Ian Firth (IC Firth OHs Solutions).

Together, they bring over 70 years of combined experience in the mining sector, offering participants practical insights and real-world knowledge drawn from extensive industry experience.

Throughout the week, participants explored industry-specific hazards, exposure assessment, control strategies and practical approaches to managing occupational hygiene challenges unique to the sector.

Dr Ross Di Corleto

The overwhelmingly positive feedback from attendees confirmed the strong demand for specialist training in this area and highlighted the value of expanding professional development opportunities for occupational hygiene practitioners working within the mining sector.

To enquire about a private course, please email office@aioh.org.au.

We look forward to welcoming you to a Basic Principles Course in 2026 / 2027.

Who attends our AIOH Basic Principles Courses?

While most students attending the BPC are emerging occupational hygienists, we also find many who come from allied or adjacent fields.

These students attend with different aims in mind, including how to: Manage and support the occupational hygiene professionals in their workforce (operations managers) Request appropriate assessments from consultant occupational hygienists Understand and interpret the occupational hygiene reports provided to their workplace, especially with regard to controls and compliance requirements Understand occupational health risks as part of their study or profession (eg. occupational physicians and nurses)

Understand how to assist workers in rehabilitation programs (eg. wellbeing coordinators and occupational physicians) Recognise how worker exposure affects health monitoring outcomes (eg. occupational physician and nurses), or Gain more knowledge in specific areas of interest in the workplace.

The one thing they all have in common by the end of the course is a great appreciation for their site occupational hygiene consultants or in house occupational hygienists!

Is there anyone in your workplace who would similarly benefit from attending the AIOH BPC?

Kristen Williams (HSE Manager - Wellbeing), who attended a 2026 Brisbane BPC has kindly agreed to share her feedback about the course Why did you sign up for the BPC? I attended to refresh and strengthen my understanding of occupational hygiene, particularly around exposure monitoring and exposure standards, to better support health risk management in the workplace.

How/Did the BPC influence or assist you in your ongoing management of OH in your workplace?

The course reinforced my knowledge around monitoring processes and interpreting exposure data, which has helped me feel more confident when reviewing results and understanding compliance against exposure standards. It has also supported more informed conversations with consultants and internal stakeholders.

April Sydney Course

CONSUMABLES NEEDED PLEASE! The BPC needs some expired charcoal tubes (226-01) for teaching purposes.

If you had any to donate, we would be very grateful, thank you!

Please contact office@aioh.org.au

What aspect of the course (if any) did you find the most useful for this, and why?

The most valuable aspects were the practical discussions around monitoring and exposure standards, along with the opportunity to engage directly with Certified Occupational Hygienists.

Being able to ask questions based on real workplace scenarios made the learning highly relevant and immediately applicable.

Would you recommend the course to others who manage OH or employ occupational hygienists, and why?

Yes, definitely. The course provides a strong practical foundation which is critical for anyone involved in managing workplace health risks or working alongside OH professionals.

May Perth Course

The latest BPCs held in April (NSW), and May (Perth) courses were completely sold out. If you or someone from your workplace would like to attend the BPC, please go to the AIOH website for online registration at Events – AIOH.

AIOH REACHES 1700 MEMBERS A milestone in protecting worker health.

From 29 members in 1980 to 1700 members in 2026. Thank you to our growing community of Occupational Hygiene professionals across Australia and abroad.

tute! i t s n I ur It’s yo

As the AIOH closes out another financial year, we are pleased to celebrate a significant milestone, reaching 1,700 members for the first time in the Institute's history.

What began in 1980 with just 29 members has grown into Australia's largest professional community dedicated to the protection of worker health. Over the past 45 years, the AIOH has evolved alongside the occupational hygiene profession, supporting members through professional development, certification, advocacy, networking, mentoring and the advancement of occupational hygiene practice across Australia.

While membership numbers naturally fluctuate throughout the year, reaching 1,700 members reflects the continued strength of the profession and the value members place on belonging to a professional community committed to protecting worker health.

Today, the AIOH represents a diverse membership base spanning all career stages, from students and emerging professionals through to highly experienced to Full and Fellows.

Of our current membership, more than 94% are active members, demonstrating strong ongoing engagement with the Institute and the profession.

The growth of the profession is also reflected in the depth of expertise within our membership. The AIOH currently includes 242 Certified Occupational Hygienists (COH)®, representing the highest level of professional certification awarded by the Institute. We are also proud to have 48 Fellows recognised for their distinguished contribution to occupational hygiene and the profession. In addition, more than 700 members currently hold professional membership grades, demonstrating the strength and maturity of occupational hygiene practice across Australia.

Encouragingly, female participation within the profession continues to grow, with women now representing 34.3% of the AIOH membership. The strongest membership representation sits within the 35 to 54 year age brackets, highlighting a mature and experienced professional workforce while also demonstrating healthy participation from emerging practitioners entering the profession.

AIOH REACHES 1700 MEMBERS

The AIOH's membership extends across every Australian state and territory, with particularly strong representation in New South Wales, Queensland, Victoria and Western Australia (don’t worry South Australia and Tasmania are slowly but surely growing a strong cohort too). This national reach ensures the Institute remains well positioned to support worker health outcomes across a diverse range of industries and workplaces.

Membership growth is not simply about numbers. It reflects the increasing recognition of occupational hygiene as a critical profession in protecting workers from health hazards and preventing occupational disease. Every new member strengthens our collective ability to share knowledge, support professional excellence and advocate for healthier workplaces.

As we celebrate this milestone, we acknowledge the many volunteers, committee members, Council, members and staff who have contributed to the growth of the Institute over the past four and a half decades.

As our membership continues to grow, maintaining accurate member information becomes increasingly important. Up-to-date member records help ensure the AIOH can effectively communicate with members, recognise milestone achievements, support certification and professional membership processes, and maintain services such as the Find a Consultant register. Members are encouraged to regularly review and update their details through the MYAIOH portal to ensure their information remains current.

We also encourage all members to help shape the future of the Institute. The AIOH Annual Member Survey is now available through the MYAIOH dashboard, and your feedback plays an important role in informing the AIOH Strategic Plan and future priorities. Whether you have been a member for 30 years or 30 days, your views matter. We encourage you to take a few moments to complete the survey. Your feedback is valued, needed and helps ensure the AIOH continues to reflect the needs of its members. After all, it is your Institute.

From 29 members in 1980 to 1,700 members in 2026, this milestone is a testament to the strength of the profession and the commitment of those who continue to champion worker health across Australia.

Thank you to all members for being part of the AIOH journey. Together, we continue to build a stronger profession and healthier workplaces for the future.

Will occupational hygienists be recognised as our own occupation?

By Kate Cole OAM, Lead Public Policy Sub-Committee

If you’ve ever tried to fill out your tax return and been frustrated that “occupational hygienist” wasn’t an option in the drop-down box, and wondered why, you’re not alone.

In Australia’s occupation classification system, occupational hygienists are not recognised as a separate profession. Instead, they are grouped as a specialisation under Occupational Health and Safety Advisers. As we know, this does not reflect what our profession actually does.

The AIOH Public Policy Sub-Committee recently submitted a case to the Australian Bureau of Statistics Occupation Standard Classification for Australia (OSCA) to recognise occupational hygienists as a separate occupation within the OSCA framework.

This is a long-standing issue that AIOH has been advocating on for some time.

Occupational hygiene is a distinct discipline with a clear focus on the anticipation, recognition, evaluation and control of workplace health hazards. Practitioners work across chemical, physical and biological exposures, with our grounded in exposure science, drawing on fields such as toxicology, chemistry, physics and epidemiology.

This is fundamentally different from the role of an Occupational Health and Safety Adviser, which typically focuses on safety systems, compliance, training and incident management.

While both roles contribute to workplace health and safety, they operate in different domains and require different skill sets.

Will occupational hygienists be recognised as our own occupation?

The current classification has practical consequences. When occupational hygienists are grouped with a much larger OHS workforce, it becomes difficult to accurately measure workforce size, demand and shortages. This affects labour market data, workforce planning and policy development.

There are also implications for skilled migration. If occupational hygiene is not recognised as a separate occupation, demand for these specialised skills may not be visible in migration settings. This can make it harder for employers to recruit qualified hygienists, even where there is clear demand.

Evidence shows that the demand is real and growing. Job advertisements across mining, construction, consulting and government regularly seek occupational hygienists as dedicated roles, with responsibilities focused on exposure monitoring, health risk assessment and control strategies. At the same time, membership of the AIOH has increased significantly in recent years, indicating growth in the profession and increased recognition of its role.

Regulators across Australia also consistently recognise occupational hygienists as specialists in exposure assessment and control. Guidance from Safe Work Australia and state regulators identifies hygienists as the appropriate professionals to design monitoring programs, interpret exposure data and manage complex health risks.

Recognising occupational hygienists as a distinct occupation would improve the accuracy of occupational data and strengthen workforce planning. It would also better align formal classifications with how the profession is already understood by regulators and industry.

Formal recognition is a practical and necessary step. It reflects the way the profession operates in practice, supports more robust data, and helps ensure the capability required to manage workplace health hazards is clearly understood and appropriately planned for. We will continue to advocate for this change and keep members informed of progress.

AIOH CERTIFICATION

CERTIFICATION EVOLUTION: ALIGNING THE COH PROGRAM WITH INTERNATIONAL STANDARDS Dr Jennifer Hines - Certification Board Chair

On 21 May 2026 the AIOH received the news they had been successful in the re-certification of the AIOH National Accreditation Recognition (NAR) status. This is an important milestone for the occupational hygiene profession in Australia.

NAR recognition provides international acknowledgement that the AIOH Certified Occupational Hygienist (COH) credential meets globally recognised standards for professional certification, supporting the mobility, credibility and recognition of Australian occupational hygienists both locally and internationally.

As part of the re-certification process, several amendments to the Certification Policy were required to ensure ongoing alignment with the latest NAR criteria. These policy amendments have now been approved and will take effect from 1 July 2026.

However, recognising that certification candidates require adequate time to plan their professional development and career pathways, the key eligibility changes will not apply until 1 July 2028.

Why the Changes?

The NAR framework continues to evolve as occupational hygiene matures as a global profession. A key focus of the updated requirements is ensuring that certification applicants possess both an appropriate educational foundation and sufficient practical experience before seeking professional certification.

The amendments strengthen the link between formal qualifications, professional competence and certification, while maintaining pathways for experienced practitioners from diverse backgrounds.

AIOH CERTIFICATION

CERTIFICATION EVOLUTION: ALIGNING THE COH PROGRAM WITH INTERNATIONAL STANDARDS What Has Changed?

1) Introduction of Pathways to COH Exam Eligibility From 1 July 2028, the updated policy requires all COH exam applicants to have attained Full Membership status via one of following pathways.

Pathway Route

Pathway Qualifications a. Undergraduate degree qualifications in occupational hygiene or related fields such as science or engineering;

Pathway 1

b. Postgraduate qualifications in occupational hygiene at an AIOH - accredited university or course; or c. Certification as a hygienist under any IOHA recognised certification scheme

Patway 2

a. Other qualifications acceptable to the AIOH Council

The revised policy introduces minimum occupational hygiene experience requirements in line with NAR prior to COH examination eligibility depending on the pathway: Pathway 1 Minimum of five years' occupational hygiene experience.

Pathway 2 Minimum of seven years' occupational hygiene experience.

These requirements are intended to ensure candidates have developed sufficient breadth and depth of professional practice before undertaking certification.

Expression of Interest for 2027 Certification Exams are now open. Sound preparation is key to success, applicants are encouraged to self-assess their readiness and allow time to build the required knowledge and experience. It is perfectly fine to wait until you are confident and ready to sit the examination.

AIOH CERTIFICATION

CERTIFICATION EVOLUTION: ALIGNING THE COH PROGRAM WITH INTERNATIONAL STANDARDS

Importantly, the delayed implementation date of 1 July 2028 provides a two-year transition period from policy commencement, allowing members sufficient time to complete studies, gain additional experience, or finalise certification plans under the current arrangements.

Ethics Training for COH Maintenance Another important change relates to maintenance of certification.

Effective 1 July 2028, all COHs will be required to obtain a minimum of 0.2 Certification Maintenance (CM) points in ethics training during each five-year certification maintenance cycle.

Ethics training may be delivered by the AIOH or another recognised professional body, provided the content is relevant to professional ethics in occupational hygiene or related professional practice.

What Does This Mean for Members?

For current COHs, the immediate impact is limited. 0.2CM points must be obtained if your certification review cycle falls after 1st July 2028.

For prospective COH candidates, the most significant changes relate to the experience requirements for different qualification pathways. Members who may be considering certification in the coming years are encouraged to review the new criteria and consider how their education and professional development plans align with the future requirements.

COH

Looking Ahead Maintaining NAR recognition is critical to preserving the international standing of the COH credential. The changes introduced through this review ensure that the AIOH certification framework remains aligned with global expectations while continuing to support a diverse and capable occupational hygiene profession in Australia.

The Certification Board would like to thank all those involved in the NAR recertification process and looks forward to supporting members through the transition to the updated requirements.

Additional Clarification Voluntary Temporary Suspension has always been available to COHs during the five‑year accreditation cycle? This option supports members who may need time away due to circumstances such as serious illness, parental leave, unemployment, or other extended leave.

Our updated Certification Policy now makes it even clearer what is required to maintain your certification while your COH status is temporarily suspended, helping ensure a smooth transition back when you’re ready to return.

Members seeking further information are encouraged to review the revised Certification Policy via the COH webpage in the first instance, and then contact either Alicia in the office or the AIOH Certification Board

The AIOH Journey

Advancing Occupational Hygiene Through Leadership, Innovation and Service

Behind every AIOH award recipient is a story of dedication, growth and a passion for protecting worker health.

In this feature, we share the experiences and insights of individuals whose contributions have helped shape occupational hygiene and support the advancement of the profession.

Their journeys highlight the diverse pathways available within occupational hygiene, from technical practice and research through to leadership, mentoring and service to the profession.

Their stories remind us that success is rarely a straight line. Instead, it is built through curiosity, persistence, learning from others and a commitment to making workplaces healthier and safer for all.

Let’s Celebrate

From Australia to Europe, A Young Hygienist’s Journey of Professional Growth Lee Cherry, winner of the 2024 AIOH Draeger Young Hygienist Award, shares insights from a once-in-a-lifetime professional development journey across the United Kingdom and Europe.

Receiving the Young Hygienist Award provided an opportunity that extended far beyond travel. It became a journey of learning, connection, and professional growth across some of the world’s leading occupational hygiene organisations and workplaces.

This report outlines the key activities, learnings, and outcomes from my attendance at the BOHS Conference 2025 and associated professional site visits conducted across England, Amsterdam, and Germany in June 2025.

Kate Jones shared her research into exhaled breath condensate and respirable crystalline silica, both of which have significant implications for exposure assessment and worker health.

The 3.5-week European program commenced in Manchester, United Kingdom, followed by engagements at the Health and Safety Executive (HSE) in Buxton, the Sellafield nuclear facility, Newcastle for the BOHS Conference and Local Exhaust Ventilation (LEV) refresher course, Amsterdam for the International Lead Association Conference, and concluded with an in-depth professional experience at Dräger in Lübeck, Germany.

The professional experiences covered a broad range of occupational hygiene themes and technical focus areas, providing opportunities to engage with leading practitioners, researchers, and innovators from across the globe.

Learning from industry leaders The visit to the Health and Safety Executive in Buxton provided valuable insight into current research and challenges within occupational hygiene.

Meeting with Helen Chambers provided an overview of the challenges associated with an increasingly reduced team at HSE, along with several innovative projects currently underway.

The visit also included experiencing the organisation’s soundproof room, an environment that was notably disorienting and offered a unique insight into the acoustic research being undertaken.

John Saunders presented ongoing research relating to dust control using on-tool local exhaust ventilation (LEV), focusing on verifying manufacturers’ claims regarding the effectiveness of LEV systems in reducing worker exposure to hazardous dusts and fibres.

Alan Beswick provided an overview of research into aerosol generation and spread during coughing, sneezing, and vomiting. This work, particularly during the COVID-19 pandemic, contributed valuable insights to national response efforts. He also discussed high-risk research involving biological hazards and potential bioweapons, including studies related to Anthrax transmission risks within postal networks.

The visit to Sellafield nuclear facility provided another unique opportunity to observe occupational hygiene principles applied within a high-hazard environment.

The facility’s operations include nuclear waste processing, waste storage, and nuclear decommissioning. Hosted by Andrew, the visit provided valuable insight into the operational challenges encountered on site and the systems in place to manage risk.

A key observation was the strong safety culture demonstrated by the team leaders who guided the tour. Their embedded knowledge of occupational hygiene practices and their ability to clearly articulate effective hygiene risk management principles demonstrated the importance of experience and competence within high-risk industries.

I also gained insight into the Site Ion Exchange Plant (SIXEP), which removes the majority of radioactive isotopes from water used in nuclear operations, ensuring discharged water remains safe and within permitted limits.

The practical value of this experience was significant, with learnings already being applied to current projects.

From Australia to Europe, A Young Hygienist’s Journey of Professional Growth Building knowledge through collaboration In Newcastle, I attended the Vent-Tech course and assisted with the practical assessment component. As I already held the relevant qualification, Adrian Sims provided the opportunity for me to facilitate the practical assessment and grade candidates.

This experience allowed me to contribute to the training process by sharing practical insights while also developing my leadership skills in an area of professional interest.

It was inspiring to see the level of education offered by Adrian and the work he continues to do through BOHS and iLEVE to raise awareness around effective ventilation and risk management.

The BOHS Conference 2025, Workplace Health Protection Conference, was a highlight of the journey, bringing together leading occupational hygiene practitioners and researchers.

Representing Australia and the Australian Institute of Occupational Hygienists (AIOH) was an invaluable experience.

Networking with professionals across Europe created opportunities to exchange knowledge, build meaningful relationships, and showcase the expertise of the Australian occupational hygiene community.

Sessions covered a broad range of topics, including: Unlocking the power of Industrial Hygiene for a Resilient and Sustainable Future – Dr Lali Japaridze, BP Regulating Occupational Hygiene Consultants – Rob Williams, HSE Mental health and personality disorders, and the role of occupational hygienists – Kelvin Williams Heat stress management and preventing heat exhaustion cases – Nezar Ali Hydrocarbons to Hydrogen, and changes in fire and gas safety – Megan Hine Isocyanate exposure sampling – Mary Cameron A particularly valuable session was “How to Give Added Value for Clients With OH Reports” presented by Kelvin Williams and Gordon Smith. The session provided practical guidance on improving occupational hygiene reporting and review, reinforcing the importance of clear, professional, and scientifically robust communication.

The New Tech Dragon’s Den session also provided an engaging look into emerging technologies and equipment designed to advance occupational hygiene practice. Presenters introduced new tools, discussed applications, and encouraged attendees to critically evaluate innovation and implementation within the profession.

The conference also provided valuable networking opportunities through social events, trade exhibitions, poster presentations, and discussions with professionals whose work has influenced the field.

From Australia to Europe, A Young Hygienist’s Journey of Professional Growth Sharing knowledge internationally The journey continued to Amsterdam, where I had the privilege of presenting as a plenary speaker at the International Lead Association Conference during their lead workshop.

The presentation, “Scientific Storytelling”, explored the importance of communicating complex technical concepts through narrative structures that engage, educate, and inspire audiences from the shop floor through to management.

The presentation was very well received, with attendees providing positive feedback. One participant later engaged my services to help communicate a challenging message to their workforce, an unexpected but rewarding outcome.

This event marked my first time presenting to a large international audience and was a significant milestone in my professional development.

A memorable conclusion at Dräger The visit to Dräger in Lübeck was undoubtedly the highlight of the trip. The experience was exceptional, not only because Dräger sponsored the award, but because of the hospitality, support, and professional engagement provided throughout the visit.

The experience began with Experience Dräger, a guided exhibition tour delivered by Heiko Schaffrath.

The interactive tour showcased Dräger’s technological evolution and current product range, demonstrating the depth of innovation within the organisation.

The visit continued through the Dräger Test Laboratories and Safety Division, where I engaged in discussions around personal gas detection, emerging technologies, reporting software advancements, calibration, bump testing, and automated processes.

The factory tour hosted by Rene Krüger was particularly impressive, providing insight into the precision and expertise involved in sensor production, SCBA headwear assembly, gas cylinder filling, and personal gas monitor construction.

The quality assurance standards, technical capability, and pride demonstrated by employees throughout the facility were truly inspiring.

The professional growth gained from this opportunity has been extensive, significant, and diverse. The learnings acquired will continue to influence my development as an occupational hygienist.

It has been an honour to represent both AIOH and Australia as a young hygienist throughout the United Kingdom and Europe, and to return as one of the recipients of the Young Hygienist of the Year Award.

I am committed to applying these learnings to advance the occupational hygiene profession in Australia and to promoting the critical role hygienists play in protecting worker health, an area of personal passion and professional dedication.

Airmet Professional Advancement Award 2025: Expanding Horizons in Occupational Hygiene This report has been written by Andy McCarthy as a summary of the Airmet Professional Advancement Award received in 2023.

This award meant so much to me, as I have applied multiple times and was incredibly honoured and humbled to receive the award. The Airmet Professional Advancement award trip was a once in a lifetime opportunity to Due to relocating back to Australia in February 2023, I was unable to schedule my trip in 2024. It was agreed with Airmet and the AIOH to postpone the trip until 2025 and travel with the 2024 recipient. The flexibility from Airmet and AIOH was very much appreciated.

The trip started very early in Adelaide to meet Peter Shiels in Melbourne to travel together. Jason Green had left Australia the week earlier for his site visit in Phoenix. From Melbourne we travelled to San Fransico and then onto Pittsburgh. First stop, in attempt to beat jetlag, as we had a full schedule for two weeks, was Primanti Brois, for a famous sandwich. This did not disappoint, and was not our only time there!

After some sightseeing, the Andy Warhol museum, the obligatory segway tour, a Pirates baseball game and a very competitive Duckball tournament, it was time to get to business.

Unfortunately, due to the political climate in the United States, I was unable to achieve my planned visits to the University of Arizona (Center of Mining Excellence) in Tucson, Arizona, MSHA in Arlington, Virginia, or NIOSH in Pittsburgh. I was however, able to meet with the people I had scheduled at AIHce in a more informal setting. We were able to spend a very informative and educational day with Dr Emanuele Cauda (of NIOSH) while in Pittsburgh who not only showed us around town, but gave us a tour of the history of Pittsburgh and its educational institutions and proud steelmaking history.

Although my trip was not quite executed as planned due to government circumstances beyond our control, it was still very valuable and was a privilege to attend, representing the AIOH and the professional Hygiene community in Australia.

Living in the United States 2022 – 2024 allowed me to create a network of Industrial Hygienists through AIHA and the Future Leaders Institute, meeting up with

these people, including members of the AIHA Mining Working Group of which I am a member) allows me to continue to maintain friendships and professional connections which are invaluable to me. Having a global network is immensely valuable in Occupational Hygiene.

Our AIOH group was hosted by SKC in Eighty-Four, Pennsylvania, which was not even close to what I expected. Seeing the equipment I have been using for decades manufactured in the United States was a surprise, as I did expect outsourced offshore manufacturing. SKC leadership and team members (Dan Baldauff (COO), Dusty Ott (Corporate IH), Andy Bragg (Sales)and Doug Dowis (Tech Support), among others, who spent their time showing us around the facility and answering our endless questions were knowledgeable, open and very accepting of the Australian team. We felt like part of the family, which extended to a local lunch and an invite to the AIHce SKC event.

Our second site visit was to Industrial Scientific in Pittsburgh. After a short, but scenic drive, we arrived to a state of the art facility. We met with Jamie Green and Brittany Sheets (Product Owner / Marketing Specialists) for a review of the history if Industrial Scientific, current flagship equipment and a preview of the yet to be released Vector gas detection system, which are going to be a game changer once released.

We were given the opportunity to ask any burning questions about gas detection, and take a look at the evolution of Industrial Scientific equipment, some of which we had all been using for well past a decade. All of this was followed by a tour of the entire facility which was amazing.

Airmet Professional Advancement Award 2025: Expanding Horizons in Occupational Hygiene

After Pittsburgh, we headed for AIHce in Kansas City. For me, the AIHce started with a full day on exposure decision analysis and statistics (PDC 105: The essentials of understanding exposure variability and IH statistics). The lead instructor for this course was Jerome Lavoue, who I had previously met while in Montreal. Having a very close interest in statistics related to exposure assessment, this course supported some of my existing knowledge and provided new information to supplement. Thankfully, I did pretty well on the quiz!

The AIHce is a phenomenal conference with so many sessions to try and schedule in. The key concurrent session I attended were based on Battery Electric Vehicles, Mining, Silica, Statistics and Total Worker Health.

All of these I hold a particular interest in, having studied, researched, published or just hold an interest in.

Every person I spoke with I recommended attendance at the AIOH conference and exhibition and I do hope this has led to some new attendees and presenters.

To sum up, the Airmet Professional Advancement Award was extremely valuable for me personally, and for the AIOH. Meeting existing and new colleagues and friend’s opens up opportunities and ensures there is always someone to call when there is a question I can’t answer.

An unmeasurable thank you to Airmet, Peter Shiels, AIOH and the Awards Committee. Andy McCarthy

Graduations

Our recent graduands included Dr Holly Fletcher whose research on won best paper at AIOH25 and recently took out the coveted AIHA Wigglesworth Award. If you missed her February AIOH webinar, we highly recommend you watch it!

Also a huge congratulations also to our recent graduates: Rashid Al Mafri, Austen Erickson, Matt Hall, Aman Kaur, Ajay Thomas and Spencer Varndell.

Research News Dr David Noi and Dr Jane Whitelaw shared their research outputs and how they inform future directions at the National WHS Research Futures Symposium in Adelaide in June.

David presented his success story which originated in his PhD research on calibrating direct reading dust measuring instrumentation (DRDMI). From his research, it has initiated DRDMI manufacturers, suppliers and users to re-think calibration and use of the instruments, and to question validity of results obtained. His research outputs ignited a spark for AIOH to produce a Technical Paper for provision of guidance on minimising uncertainties when measuring airborne dust and how users can calibrate and use the instruments, interpret results and understand potential errors and limitations when using the DRDMI. The Paper is a fabulous resource and it’s now available via the AIOH website.

How good is that?!

Course News During May, our occupational hygiene students have enjoyed a practical workshop teaching session for the ‘Occupational Hygiene: Control’ subject as part of the Masters of Occupational Hygiene postgraduate degree. The workshops are all about getting ‘hands on’ experience at undertaking ventilation assessments and going deeper into the variety of control strategies which can be used to reduce workplace exposures.

We are grateful for the support from our industry colleagues from various industry experts during the workshop who shared their knowledge with the students on specialised topics such as welding controls, spray nozzles used in dust suppression systems (with a personal presentation and demonstration from Jon Roberts who featured in a recent AIOH Webinar), pressurised heavy plant cabins (Liam Wilson), barriers to implementing controls and influencing change (Scott MacDonald), and respiratory protection (by the gregarious Mark Reggers).

Mark Reggers Talks about Changes to the Respiratory Protection AS/NZS/ISO Standards The new AS/NZS ISO respiratory protection standards are here!

Over the last year, Standards Australia, the AIOH and RESP-FIT have released a number of articles[1] and webinars[2] on different aspects of the new AS/NZS ISO standards. But to gain some personal insight and advice into what it’s all about and what we should be doing to prepare, we sat down with Mark Reggers (RESPFIT & SF-010 Chair & ISO standard member) to learn more. Thanks, Mark!

Why are the respiratory protection standards changing?

All standards have review dates, every 10 years or so, because obviously technologies change and make sure they are still relevant for what is going on in industry & workplaces. So, when it came to reviewing our respiratory protection standards, the SF-010 committee knew way back in 2010 that there were ISO standards being developed. So, it would have been silly to go and review or make their own Australian standards knowing the involvement we have in the international standards community. What wasn't quite as expected was the time it's taken for those international standards to be completed!

Australia is the first country globally to be going through this with what we are adopting locally.

We're in the front seat of this process and all the learnings that will come along with it!

Who the SF-010 committee are and what they do?

The SF-010 is the Standards Australia technical committee who overview standardisation in respiratory protection and include some amazing and hard working occupational hygienists from all areas within the field, regulators users of respiratory equipment plus a number of manufacturers and representative bodies.

What are the replacement AS/NZS ISO standards called?

The AS/NZS 1715, which as we all know covers the selection use and maintenance of respirators, will end up across 4 different standards called the 16975 Selection use and maintenance series.

SA/SNZ TS ISO 16975.1 covers the respiratory protection program requirement and selection steps, so for workplaces, is still going to be the one main standard they will use the most, I would say, and the one that the RESP-FIT online respirator selection tool is based on.

SA/SNZ TS ISO 16975.2 is a condensed version of Part 1 and is different only in the depth of detail that it covers. So, it will cover what is required but not go into the details of the ‘why’.

AS/NZS ISO 16975.3 covers the fit testing methodologies – the processes, the pros and cons. It is more detailed then the 1715 fit testing chapter section, so if you’re a workplace doing internal fit testing then that would be the reference you’d probably most likely want to get your hands on first, as a reference.

ISO 16975.4 was added during the pandemic years which to no surprise is about selection of respirators for pandemic/endemic/outbreak of infectious respiratory diseases.

What will we see instead of AS/NZS 1716?

Instead of the single AS/NZS 1716 testing standard, we’ll see a series of new standards, which will detail the testing requirements and capabilities of respiratory protection. There are quite a few but essentially, it is like taking all the elements of 1716 and spreading the sections into different documents, which makes them easier to update in the future. These standards will be very relevant for manufacturers, testing laboratories and accreditation bodies; however, most Occupational Hygienists will be concerned with the new standards replacing AS/NZS 1715 being what is used in workplaces for selection.

So, in a nutshell, what are the major changes with the ISO standards?

One of the major changes is we’ll be moving from a type-based respirator classification to a performance-based classification of an individual respirator product. So, as an example, currently all half-face respirators with a P2 filter from any manufacturer that meets the AS/NZS 1716 would be given a protection factor of 10 - so they’re all classified the same.

Under the ISO classification, the protection factor (or Protection Level to use the new terminology) will depend on how that individual product combination performs. Under the current standard, we know that the products may look similar, but their actual performance can be very different! We want manufacturers to be designing things that put technology to the test and demonstrate that it protects people which is what really matters.

Another key new difference is the introduction of work rates that products will be tested to and rated. As a wearer works harder, breathes heavier this will have an impact on the respirator thinking about the pressure impacts in the respirator and on the seal, the airflow through a filter cartridge etc. The standards try to factor this real-world impact into how products are rated. So, a respirator may have different rating for different work rates, meaning this needs to be assessed through the respirator selection process.

Something I really want to highlight, though, is that a respirator is still going to look like a respirator. A worker still needs to use it appropriately. It is still the lowest order in the hierarchy of controls. it still comes down to the wearer, fitting it, wearing it correctly, doing all the right things. Again, you know, it’s still the lowest order of hierarchy of controls - that doesn't change.

What other some other changes that stand out?

One of the key differences between AS/NZS 1715 standards and the AS/NZS ISO ones is the higher protection factors that will come with the AS/NZS ISO standards. When we look at our existing protection factors from 1715, they've been pretty the same since, you know, the 80s and 90s; whereas there's been a lot more work internationally looking at protection factor numbers. So most other countries do have many types with higher protection factors than Australia has had,

The SF-010 committee will be reducing a number of the ISO protection factor levels, because we are the first countries to adopt and there still information and knowledge to be determined about how these rated products will actually perform in the workplace. But the protection levels that the Australian committee have proposed in the AS/NZS ISO standards, will be higher than our current highest protection factors in AS/NZS 1715.

I think this a key thing for workplaces, but also important as it overlaps with the reduction of many WELs (workplace exposure limits) which we need to consider when thinking about reducing exposures. So having these products that have a higher protection factor will add to the scope of application in workplaces.

So, thinking about real world applications of the higher protection factors (the highest one being proposed by the committee is 500+) is that anything above 500 times the exposure standard should be highlighted as a very high risk environment! And as a way to proceed with this type of exposure, you’d be doing some pretty serious risk assessing and looking at all your controls, which should be happening anyway, and not relying on RPE as your primary control.

How will selection of RPE look under the new AS/NZS ISO standards?

Similar to how it looks now! When a respirator is selected under the new AS/NZS ISO standards, you’d start with the same questions as now, that is, ‘what do I need to do to reduce a worker’s exposure? Is it going to be suitable to be worn with other PPE and under what circumstances?’

However, under AS/NZS ISO ratings you wouldn’t just say ‘I need a P2 half face to achieve a protection factor of 10 from any manufacturer’.

Using our new AS/NZS ISO terminology, you might decide you need a Protection Class 2 (PC2) level of protection with a F3 particulate filter, which may be a half face or a fully face in a certain manufacturer’s range of products. This is more realistic to use actual proven performance and not limit innovation and technology to fit into ‘standards’. The standards will also be more human-centric as part of the selection process.

One of the things I really like about the ISO 16975.1 is the way that they've laid out that selection process in order. I think it's done well to make it easier for the reader to step by step, methodically, logically go through all those questions. And there's some fantastic flow charts.

Can you explain what human-centric means for workers?

The AS/NZS ISO respirator testing component (the TIL, or total inwards leakage test), will be based on the performance of the actual product combination, including what type of work are they doing and the physiological load as I alluded to earlier. How hard the worker is breathing also comes into the classification as a formal part that selection process, not just the filter. Under ISO, you'd be thinking about the worker’s physiological work and their metabolic work rate, when choosing a respirator as this makes up part of the rating. It might seem overwhelming but at the heart of it the process of selection is still the same. In summary, we're trying to fit the respirator to what the worker is doing, rather than fitting the person to the respirator.

Tell us more about the work rate component!

So, in ISO world, products will also have a W rating for work rate, work rate one, two, three and four. For example, if we think about a P2 product, if I'm standing or sitting at a desk my breathing rate's going to be much lower. So, pulling air through the filter, that negative pressure amount inside the facepiece is not going to anywhere near as high as if I'm doing a high physiological task. So, the product combination can be tested against increasing flow rates to determine the impact on a filter and inward leakage. Does an increased flow rate pull particles further into the filter, or all the way through a filter? Does the seal hold up with that increased negative pressure?

How will we determine this? Do we have to measure a workers work rate?

The AS/NZS ISO standards use very broad categories of type of work, which is linked back to ISO 8996, which occupational hygienists use thermal stress. Work rates will be based on the average work rate across your working day, which for most workers is likely to be W1 or W2.

Workers may have ups and downs, but on average, you know, it's going to be at a certain level that you can subjectively assign.

A work rate 3 and work rate 4 is more for the rescue response type, where, for very short periods, that you are going to maximal capacity.

You know, if you're wearing an SCBA, climbing a ladder, or doing some really hard physical work where there will be short, very high peaks of pressure, or air getting pulled through a

Certain special applications may mandate a product be a certain work rate rating to reflect the expected use case & environments e.g. fire fighting.

There is a lot of guidance of the sort of the type of work and trying to, you know, align some of these descriptive sorts of tasks to what is happening as well, in the standard.

Do you believe that there will be a tendency to over-protect for work rate, like workplaces tend do for hearing protection?

Well, I think it's human nature to want to go for the highest, thinking the highest is always the best. So, I tend to agree that there'll be workplaces that won't fully understand the ratings and will want to adhere to uniform protection, and that will probably happen. There's nothing stopping a workplace wanting to pick something as W4, but you'll probably find that there won't be too many products that will meet a W4, which may be used, for example, firefighting!

But let's say we have a respirator that meets a W4 as an example. Is that going to give you a higher, better filtration when you're not working at that high work rate? I would expect that it's going to be much higher breathing resistance for 90% of the task, because it is rated to perform very highly when you're sucking air through at those peak work rates when you're not, so you're actually likely going to be adding more physiological stress or breathing resistance on the wearer for 90% of the task.

I think that short periods of high work rates, on average, will still be covered by that W1, W2 work rate. I think hearing protection is a good analogy in that, you know, a class 3 hearing protector 3 can protect against a high noise environment over a short period.

Does the ISO standard involve learning lots of new terminology?

There is new terminology, which is a bit to like learning a new language, but I think people overestimate how difficult it will be to pick up! Some of it might feel overwhelming, but some of it's going to be, I think, going to be fairly obvious, for example, an organic vapor filter will now be labelled OV, as opposed to A! Most people are just going to want to connect the dots between the old and new world, for example, wanting to know what the P3 will be equal to? For that reason, an equivalence table was created in the online respirator selection tool (https://rpd.respfit.org.au/translate/) which is where the equivalent rating in the tool come from. There will also be future documents from Standards Australia to help with that as well. As you go through these resources, I'm hoping people are going to realise it's actually not that complicated. We just know that this now equals that… Soon, this terminology will be second nature!

What is the timeline for transition to the new ISO standards The current plan is that AS/NZS 1715 and 1716 standards will become superseded the start of 2030, which may seem a long time away, but will fly by before we know it. So, we’re trying to use this period to make industry aware of these changes and for manufacturers to start this journey. This isn't a quick flick of switch and all it all happens!

For most manufacturers, they're working today on the products that are planned to be released now until 2030 and beyond, because there is a process and it does take time. So, this current period is why we keep referring to the transition period, where we’re hoping that manufacturers will be doing that work so that in the coming years, you'll see ISO products starting to hit the market.

Just because AS/NZS 1716 is superseded in 2030, it doesn't mean that on that date you'll have to clear out every respirator out of every cupboard! It doesn't mean people can't continue to use respirators that meet the AS/NZS 1716 standard, and it also doesn't mean that manufacturers must stop selling AS/NZS 1716 products. But it should signal the intent that the AS/NZS ISO suite of standards is the more current standard and up-to-date standard technology! So hopefully in that time period, it will be a sort of phase out of AS/NZS 1716 products being released and phase in of AS/NZS ISO products will increase. I expect this will be over a significant period of time given how much AS/NZS 1716 products are out there.

Can you see a problem where no new ISO product matches your requirements?

Absolutely. With Australia and New Zealand being the first global country or regions to locally adopt this fully, we're going to be right in the overlapping transitional phase-in-phase-out period in the early stages when we start to see, you know, ISO classified products come to the market. There's not going to be many to start with. So, there will certainly be a period where you'll work out what your level of reduction is, but you can still use and select respirators that meet AS/NZS 1716. So yes, we're going to have a period of overlap where workplaces will have to be looking at both AS/NZS 1716 and AS/NZS ISO products.

What can we be doing now to prepare?

This whole AS/NZS ISO transition for people selecting respirators, is to be thinking about that new terminology and how it lines up with the ratings we are all so familiar with! Nothing will change for them except the fact that they need to know how it works and the new terminology. So, you should use the tools to become familiar with the new the terminology, use the equivalence table and then start applying it to respirator selections that you're actually already doing now. Occupational hygienists (or anyone) can use the free Online Selection Tool to do this! Start using it then then applying the results to the selections that you're actually conducting every day! Just as occupational hygienists were ‘trying out’ the WELs with current workplace exposures ahead of the transition in December 2026, people should be learning and applying the AS/NZS ISO standards!

Tell us more about the online selection tool The online respirator tool selection tool (https://rpd.respfit.org.au/) was created to get very close to aligning with the full content and processes that workplaces will go through when applying the SA/SNZ TS ISO standard 16975.1.

The Tool began with grant from the AIOH Foundation to begin the web development and framework process, and then the New Zealand Occupational Hygiene Society to also come on board and contribute financially enabled us to broaden the scope.

There was a gap that I could see that would help, hygienists, workplaces and workers overall to navigate this respirator selection process that has always been there, but put it in a form that is online, accessible and structured. The tool is free and it's not about any one manufacturer or brand because it's purely about the selection needs of what that person is doing and other selection factors as well.

The selection principles don't change between the old and new standards, so the Tool produces outcomes for both the AS/NZS ISO and the AS/NZS 1715/1716 ratings. This will also assist with connecting the dots between what we're familiar with and where we're going!

It was created to facilitate and benefit broadly the Australian and New Zealand community of hygienists, respiratory fit testers, workplaces and workers to use.

Which is why I'm so excited about it and put a lot of work into it that, it's out there and hopefully being used and helping people on this journey on ISO transition or just selecting respiratory protection to make sure it's suitable and appropriate for a worker. (Ed: the amount of work Reggers has put into this tool is remarkable )

😁

And so, this tool is, ultimately as a starting point is to make it easier for workplaces to go through all the elements of selection, to select a product, a rating that is suitable for what they're doing. And I keep going back to respiratory protection is more than the right filter.

I think people will very quickly pick this up. It will obviously depend on the time you have and how often you do respirator selection as part of your work, but the tools are there to help start you on that journey wherever you are.

This is also the first version. The more the people are using it and more questions about when it doesn't work or doesn't apply well - when in doubt, ask a question! There's also contact details on the online tool. We have certainly got plans to continue to evolve and iterate!

The selection tool is amazing - are there any other tools we can use?

Yes there will be! We’ve recently submitted to Standards Australia is a mapping document to line up each section of 1715 to the equivalent section in 16975.1 and 16975.2 to be published later this year.

Will anything change with the way we fit test ISO respirators?

No! At the heart of an assigned protection factor or protection level of a respirator (if it's a tightfitting respirator), is that fit is still critically important!

Traditional fit testing methods are part of the ISO standards. ISO and AS/NZS ISO 16975.3, includes the ATT, CNC & CNP methods, which we base the RESP-FIT program on the AS/NZS ISO framework of categories. There'll be different fit factor numbers with the ISO products, but at the heart of it, no, it still comes back to ‘does that respirator fit, can that respirator fit, does that wearer know how to wear it and how to achieve that fit replicating on the job’ within that fit test to give the worker confidence.

Can we have input into what are manufacturers are doing?

Well, the best thing is talk to manufacturers. We have a fantastic relationship with the respirator manufacturers, you know, as an occupational hygiene and safety community. We think about how many respirator manufacturers, distributors are involved in our conference every single year because we can't do what we do as hygienists and protecting workers without having these fantastic products that go into workplaces. They go hand in hand.

The other way to provide feedback is to the RESP-FIT board members. Additionally, Jane (Whitelaw), and I are regularly talking to the Australian Standards Committee, along with a whole number of occupational hygienists that sit on the SF-010 committee. I think there's number of different ways that communication can happen. And part of that is understanding what the AS/NZS ISO framework looks like, which is part of this kind of communication we're getting out there today.

The more that manufacturers hear about what the needs and gaps are, means they might be the first to fill that gap, so there's some incentive for them as well. It does get complex for global organisations when we have different certification and standards development, because when you change one little thing, there absolutely will be a ripple effect across the globe.

If we have questions regarding the standards, where can we go for help?

Australian Standards have a flagship respirator page (https://www.standards.org.au/flagshipprojects/respiratory-protection-standards) which is the place for all the current information on the transition. It has recordings of the webinars and FAQs, as this is where these new documents will eventually be once completed. There will be a lot of information on this page, plus an email address for contacting Standards Australia.

Also, the RESP-FIT webpage also has a number of links to all the resources that are out there, for people to begin the journey. For the really specific and detailed questions, there’s the general RESPFIT website which will come through to myself and the RESP-FIT board. There may be specific workplace situations where the very specific applications AS/NZS ISO standards need to be applied. By asking these questions, we all learn or may even find gaps which then also feeds back into the ISO consultation process as well.

This also speeds up the potential global adoption because we're going to be improving the standards because being applied. You know, there's only so many times you can bounce ideas around in the committee, and things looks good on paper, but until it hits the ground in the real world, you realise things maybe don't quite make sense. So, this is all part of that continuous improvement!

What are the most common questions you’re currently getting?

Most of the questions I commonly get asked are what we’ve discussed today! The when, why and how and comparison of the old world to the new! This really is a journey for Australia and New Zealand leading the world with our transition into ISO classified respirators. We will encounter things we haven’t anticipated so I welcome questions from all respiratory protection stakeholders (workplaces, manufacturers, distributors, fit testers, accreditation bodies, testing laboratories, regulators) to keep the conversation going to feed back into our Australian SF-010 committee and the ISO committees.

Thanks so much for your time and advice, Mark!
