President’s Update Behind

the scenes with Tracey Bence

At the risk of sounding dramatic –has anyone else felt the last few months have been reminiscent of a Dickens novel?

As Dickens wrote in A Tale of Two Cities: “It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of light, it was the season of darkness.”

Things are moving fast for most AIOH members. We’re in high demand for our expertise in exposure assessment and passion for the science of worker health protection – is this perhaps our season of light?

For many of us, it’s a challenge to keep up with our ‘day jobs,’ let alone what we give to our professional development and the AIOH. So hard hats off, here’s a shoutout to the hardworking operations staff, committee members and external representatives. Thanks for your expertise – we value your wisdom.

As the season flew by, you may have missed my ‘Top Three Best of Times,’ something of a nod to our 2023-2028 Strategic Plan to advocate for raising standards in worker health protection. So here’s a recap:

1. After 10 years, hundreds of thousands of NSW workers reclaim their right to audiometry.

2. After one in four engineered stone workers gets silicosis, WHS Ministers agree to better protections from high-risk silica work.

3. After years in the SWA Workplace Exposure Standard (WES) review process, here’s a sneak peek of the first lowered WES as Respirable Crystalline Silica at 0.025 mg/m3 TWA.

As to my moments of incredulity and darkness, I’m pleased to say that’s not where this story ends. As always, for ideas, questions and connections – email me.

All About Psychosocial Hazards

Healthy people, healthy culture

If you’re an employer, it’s time to pay attention to psychosocial hazards. By understanding detailed facets of psychosocial hazards in the workplace, you can create a safe and healthy work environment while boosting productivity and employee satisfaction.

What are psychosocial hazards?

A hazard is something that can cause harm; to people, buildings, equipment, or the environment. In this context, psychosocial hazards relate to the design of work, how it’s organised and managed, and how that affects a worker’s psychological or social wellbeing.

Psychosocial hazards can take numerous forms including:

• Work strain

• Social isolation (working alone)

• Bullying and harassment

• Exposure to trauma or violence

• Job insecurity

• Long working hours

• Not enough work hours

• Organisational change

• Work pace

• Lacking leadership

• Lack of structure

• Shift work and fatigue

Discover more about these and additional information from Safe Work Australia.

The effects

Psychosocial hazards can be insipid; unlike physical hazards such as equipment or chemicals – they’re not always visible. Their subtle nature means they often go unchecked and can develop and worsen cumulatively. This can lead to chronic anxiety, stress and depression and even extend to physical health issues.

The big picture

A holistic focus is becoming the norm throughout Australia. In May 2021, NSW became the first region to execute a Code of Practice: Managing Psychosocial Hazards at Work. Western Australia followed suit in February 2022, then Tasmania in January 2023, and Queensland from 1 April 2023.

The new WA legislation, released in February this year, incorporated psychosocial hazard regulations for the first time, putting them in the same standing as physical hazards.

Importance of regulation

To ensure employees have the best possible working experience, employers must assess the risks and take action concerning issues which could cause psychological harm.

And in doing so – create an improved and more considerate work environment.

Psychosocial hazards can be subjective; every individual experiences and reacts differently to hazards. They can also be complicated and interconnected with far-reaching impacts, from mental health to relationships.

Take psychosocial care

Legislated or not, there are ways to put caretaking measures in place in the workplace. Understanding the environment and assessing potential psychosocial workplace hazards, then taking action to reduce or remove them is one such step.

Employers and employees can institute training to recognise and manage psychosocial hazards, then establish policies and procedures to mitigate hazards such as workload, stressful activities, anti-bullying and harassment. If an employee experiences a psychosocial hazard –access to counselling is crucial, as are having systems to report and examine these experiences.

The Filter: AIOH’s Official Publication Table of Contents | May 2023 Issue

Keep an eye on absenteeism rates, missed deliverable timeframes or increased work hours so you can identify trends. Increased rates in specific areas or roles can indicate psychosocial hazards in effect.

Some workplaces may need more distinct psychosocial hazard evaluation and safeguarding measures. Providing psychosocial hazard assessments and prevention measures helps identify and manage risks and add value to your workplace.

Business owners

For consultants who provide advice and manage psychosocial risks for clients and their organisations, there are several ways to approach wellbeing. To create a healthier and more successful work environment:

• Create boundaries around working hours

• Practise self-care

• Establish a support system

• Set realistic workloads and deadlines

• Communicate expectations

• Maintain social connections (even if virtually!)

• Review and learn from incident reports

• Evaluate prevention and control measures

• Seek professional help when needed

The COVID-19 Disruption

Effective management of psychosocial risks has become increasingly important. In the age of COVID-19, working from home, and social isolation – the pandemic has left lingering unpredictability and upset in daily life. As a result, there has been an increase in pervasive feelings of overwhelm, which can carry over into work environments.

Remote work and lasting social isolation have reduced social contact with colleagues, amplifying loneliness and disconnection. With the prevalence of working from home, the boundaries between work-life and personal-life separation have blurred. This has resulted in increased instances of burnout.

The people-first evolution

We’ve all felt stressed at work, some of us with no avenue for help or support. Gone are the days of suffering in silence – with the emerging focus on psychosocial hazards, proactive measures are not only a good idea, they’re becoming law. Awareness of these risks and the damage they can do is an important step forward that will positively impact all industries.

Emerging Hygienists Group

You’re not alone; grow in company

The Emerging Hygienists Group (EHG) has been busy since its official launch at the 2022 AIOH conference. We continue to build a following through our multiple networking and development events. Our LinkedIn group now has more than 250 members.

Ask me anything

This regular series offers opportunities for EHG members to learn from the best and brightest in our community. In January, our first presenter, 2022 president Kate Cole, graciously fielded questions about leadership in occupational hygiene.

Look out for our next Ask Me

Anything session. They’re your chance to ask a veteran of the field… anything!

In our April 2023 session, we heard from Andrew Orfanos about how he started in occupational hygiene and his most memorable career moments.

Mitchell Thompson, the AIOH membership and qualifications chair, will host an event on how to progress through the AIOH membership levels and how emerging hygienists can prepare to become certified occupational hygienists.

Talks over toast

In our recent online social event, Talks Over Toast, 12 emerging hygienists from across the country gave valuable insights into hygiene practices from various industries. Noise-induced hearing loss and emerging hearing protection technology was a central theme of the event. The group also discussed how crucial an enduring hygiene culture is on worksites.

These sessions are a fun way to meet fellow emerging hygienists, learn from each other and have a laugh. See you at the next one.

Cecilia’s rundown: a new attendee’s account

Recently, members of the EHG met for our Talks Over Toast session. The group addressed various issues hygienists face in workplaces and on job sites. The conversation flowed naturally: I felt comfortable sharing my views and opinions with the group.

It was great getting perspectives from hygienists working inhouse versus those working as consultants. Hearing from hygienists working in government agencies was also valuable.

Workplace culture and attitudes towards hygiene matters was an engaging topic, particularly within the construction industry. Everyone contributed, and I enjoyed the open, honest discussions and listening to diverse experiences.

Attendees of our most recent online event Cecilia Mason

We also explored occupational noise at length. I learned about different kinds of hearing protection devices and emerging technologies. It was great to have more experienced hygienists share their wisdom with the newer folk in the group.

I encourage anyone in the industry to join, especially newcomers or those hoping to grow their network and learn from others. The sessions are casual yet informative – I look forward to meeting more hygienists at the next one.

Get Involved

To build our community throughout the year, the EHG working group will host two monthly online events and an in-person event at the 2023 AIOH conference. If you consider yourself an emerging hygienist, please join our LinkedIn page using the QR code below. This is a space to share news, ask questions and build your network.

If you’re a senior occupational hygiene professional interested in hosting an event and sharing your knowledge with the EHG – let’s chat.

A conversation with career chameleon Chris White

We asked one of our WA hygienists, Chris White, to give us an insight into his journey as an occupational hygienist. And what a colourful and diverse journey he’s had.

Meet Chris

Chris currently works in occupational hygiene and occupational health and safety and has been a member of the AIOH for 18 years.

Much of his early work was as a scientific officer for WorkSafe WA and the then Department of Mines and Petroleum. In recent years, he’s been a consultant in the resources sector in offshore and onshore operations.

Having spent his early life in lighthouses and the merchant navy, it’s no surprise Chris likes remote work. He’s looking to return to the FIFO lifestyle soon.

An illuminating start

“My father was a lighthouse keeper in the years before electrification. Living on several remote and land-based stations around Western Australia and the Northern Territory, my early years were full of stories. Naturally, when I was old enough, I went to sea, spending time on the ships that service Australia’s lighthouses.

It wasn’t all smooth sailing; an accident at sea changed the direction of my life. In hindsight, I’m grateful because this led to a lifetime of constant change and new opportunities.

Chris White

Early career

I worked for several years in mechanical workshops, including a stint as a heavy haulage truck driver. I then started on the challenging and rewarding road of mature-age university study while training as a fabricator welder at night. Eventually, I became a TAFE welding lecturer.

After I graduated with a Bachelor of Health, I took on two roles as a research officer. The first was with the Fire and Emergency Services of WA, where I reviewed the literature on the potential effects of bushfire smoke on firefighters. I also worked with the University of Western Australia’s Occupational Epidemiology Group, following the Wittenoom asbestos exposure cohort.

I responded to an opportunity to work as an inspector at WorkSafe WA. It was probably logical that I’d work for the transport team, but that position evolved into an inspector/scientific officer role. Seeing so many types of workplaces and extensive workplace exposures through WorkSafe resonated with my life experiences.

During that time, I took on a Master’s Degree in Occupational and Environmental Health at Monash, going straight onto the Graduate Diploma Program of Occupational Hygiene at Deakin University.

Mine time

After WorkSafe, I worked at a remote WA nickel mine, initially as a lagger in the refinery before moving into a small troubleshooting team as a crane driver and rigger – very enjoyable! Given my background, I was soon transferred to the safety team to conduct a dangerous goods survey for the regulator. The refinery consisted of three separate major hazard facilities with plenty of other high-risk chemicals in play, so it was a real challenge.

In 2007, I became inspector/ principal scientific officer at the WA Department of Mines and Petroleum, starting a new chapter: occupational hygiene within the mining sector. While regulatory positions in occupational hygiene can be less hands-on concerning assessments, the sheer breadth of the role (across hundreds of mining and processing operations) was extremely rewarding.

In 2013, I left the department to become the compliance and hygiene manager of a large magnetite mine where fibrous minerals were a significant occupational hygiene hazard. In 2018, I consulted as a hygienist on a dust management project in a large gold mine.

Contract and consulting

Being exposed to a broad cross section of occupational hygiene topics has been a blessing, but sometimes I feel like a jack of all trades and a master of none. Maybe that’s why I’ve never felt like a true occupational hygienist and remained a provisional member of the AIOH for 18 years. I value the institute and its efforts and support the valuable work of those with extensive knowledge and experience.

Recently, I’ve worked in contract and consulting roles, some proving incredibly interesting, specifically working for Philip Hibbs and his team.

I conducted a noise and human factors survey on a Collins Class submarine, which was a real privilege. I spent a sweltering month surveying mercury and naturally occurring radioactive materials in the confined space compartments of a floating storage and offtake crude oil vessel. I was also involved in exciting research opportunities in fibrous minerals and respirable crystalline silica with my good friend and colleague, Laurie Glossop.

I love the limitless nature of occupational hygiene, its reach and impact in every workplace and its endless learning opportunities. With more advocacy and action needed to protect worker health, I’ll keep using my trade and engineering experience to reduce risk by developing and implementing controls.

I can’t wait to see what comes next.”

He managed a large team of (wonderful) hygienists covering many occupational hygiene hazards. Chris loves both the science of occupational hygiene and practical tasks. Chris spent an exhilarating 36 hours conducting a noise survey and associated human factors on a Collins Class submarine. He remains in awe of those who serve.

Committee Update

A COH board brief

Certified Occupational Hygienists (COH) exams

If you’re interested in sitting the COH, please submit your “expression of interest” form as soon as possible. There’s loads of interest but limited capacity.

The COH exam schedule for 2023:

• May 2023 New Zealand (one vacancy)

• September 2023 Perth

• December 2023 Melbourne

Preparation is everything

The COH exam tests the breadth and depth of your occupational hygiene and critical thinking skills, including how well you articulate your responses. Full members are eligible to apply, but past pass rates demonstrate that less than five years of field experience is unlikely to give you the appropriate skill set to successfully complete the exam (even with the relevant qualifications).

My advice? Get your hands dirty. Go into the field and undertake sampling in as many different environments as you can.

Surround yourself with mentors and occupational hygienists with more experience who can guide and challenge you.

For those intending to undertake the COH exam – please test yourself with a trusted mentor to gauge whether you’re ready before applying.

Certified Occupational Hygienists (COH) audits

The COH board updated the AIOH Certification guideline in December 2022. All COHs and full members intending to undertake their COH exam – please familiarise yourself with the policy update.

For COHs due for recertification, audits for the 2018-2022 cycle are currently underway. Final results will be available by the end of May 2023 with letters and updated stamps issued from June 2023.

Leaving a legacy

At the University of Wollongong, we’re not just about creating a community of practice and inspiring the next generation of leaders. We want to leave a legacy – this is the 5th pillar of our AIOH Career Development Pathway.

I’m excited to introduce our latest PhD conferral: Dr Kerrie Burton for her thesis on “Do AS/NZS respiratory protection standards for filter penetration ensure that worker health is protected against nanoparticle sized diesel particulate matter?”

The legacy of Jen Hine’s PhD on emission-based maintenance to reduce diesel exhaust emissions (DEE), worker exposure and fuel consumption was the starting point for Deon Swanepoel’s PhD research on improving the overall productivity of underground diesel fleets. Read his literature review here.

Photo by Bret Kavanaugh/Unsplash Kerrie celebrating with two of her supervisors: Jane Whitelaw and Professor Brian Davies

This systematic literature review focussed on the reported benefits ascribed to the utilisation of emissions-based maintenance (EBM). Although there is evidence to support EBM reduces diesel particulate matter (DPM) and worker exposure to DPM, the available quantitative evidence is limited to support that EBM improves fleet management, maintenance cost, or resulted in reduced dilution ventilation.

Are you a practitioner looking to become a professional?

Enrolments for spring 2023 are now open, so apply for the dual accredited Master of Occupational Hygiene. If you’ve decided to pursue a career in Occupational Hygiene, have completed the AIOH Basic Principles Course and have workplace experience, you might choose to get started with a Graduate Certificate in Occupational Hygiene.

Commonwealth-supported places are available and affordable for domestic students: a Graduate Certificate of four subjects costs as little as $4,000 in fees and can be completed part-time in one year.

Are you interested in making a difference and leaving a legacy? We have PhD scholarship opportunities coming up later this year so contact me now.

“One of the hardest things to do in the world in educational terms is the PhD, but the rewards are amazing. The self-fulfilment and satisfaction you achieve from it pushes you to go through all the hard work and toil,” says Prof Andrew George, Head of Graduate School, Imperial College London.

Our courses integrate practical hands-on time and networking with practising COHs to focus on occupational hygiene techniques and apply skills and knowledge to a broad range of workplace issues. What’s more – our support and networking are legendary. Contact Jane Whitelaw for more information or apply now.

Our newly accredited programs

We’re introducing two recently accredited programs in occupational hygiene. Firstly, the Master of Occupational Hygiene, which requires 18 months of full-time study, and the dual accredited (AIOH and AIHS) Masters of Occupational Hygiene/ Occupational Health and Safety Science, which requires 24 months of full-time study.

Both programs offer Commonwealth -supported positions for domestic students and emphasise hands-on learning, focusing on work-integrated experiences. Each week, students have the opportunity to learn from experienced, AIOH-certified occupational hygienists during lectures, practical classes and field visits.

In the final semester, students undertake an occupational hygiene research project, allowing them to apply their newly acquired skills and knowledge to real-world problems.

This semester, our students are researching various topics including:

• Welding fume exposure in a manufacturing setting

• Isoflurane anaesthetic gas exposure in animal research laboratories

• Chlorine dioxide exposure during disinfection activities in a gnotobiotic research facility

• Respirable dust and crystalline silica exposures for drill and blast workers in coal mines

• Polycyclic aromatic hydrocarbon (PAH) exposures of hot asphalt workers in road construction

PhD research programs are also available at UQ with current PhD students working on:

• Characterising coal dust exposures in underground mines

• Investigating the potential for psychosocial impacts from the use of respiratory and hearing protection

• Exploring the effects of time-ofday-dependent, dynamic indoor temperatures on the health and thermal wellbeing of workers.

The BPC Brief

The AIOH BPC is back for 2023

The first Basic Principles Course (BPC) has just wrapped up in Melbourne, with 18 students keen to learn more about the wonderful world of occupational hygiene. Presenters included Linda Apthorpe, Jen Hines and Kieran Brookes.

We also appreciated our guest presenter, Luke McKee from 3M Melbourne, who demonstrated fit testing equipment for respiratory protection. Airmet Scientific and Active Environmental Solutions (AES) generously supplied the course equipment to help students understand the practical side of occupational hygiene.

Our students always love the course, and this session was no exception. Here are some of their testimonials:

“I recently completed the Basic Principles Course in occupational hygiene. The course was well-structured, informative and well-presented. My biggest takeaway was how diverse the OH field is and how that translates to different industries. For a greater appreciation of occupational hygiene risk and management, I recommend anyone working in the safety space to attend.” Leigh

“Wow, what a course! There’s so much to learn about occupational hygiene, and the BPC is an excellent overview. The information helped me identify my team’s health risks and quantify and control them. Both the practical and trade sessions demonstrate best practices and multiple options. Thanks for a great course with knowledgeable and skilled trainers.” Anthony

“The Basic Principles Course opens up a world of further study. A fantastic overview of a range of topics, the trainers shared their wealth of knowledge, delivering clear and engaging information. I recommend this course to anyone looking to understand different hazards at their workplace and techniques on how to monitor and manage them.” Melbourne Student

A Global Perspective

Keeping a global eye on our profession


The American Industrial Hygiene Association (AIHA) is running their annual AIHce EXPO 2023 Conference from May 22-24 which is also available in a virtual format.

ANOH 2022 Conference

The 6th Asian Network of Occupational Hygiene Conference was held at the Sakala Resort in Nusa Dua, Bali, from September 19-23 2022. A sizable contingent of Australians made-up the 200+ delegates, including four former AIOH Presidents.

Prof Donguk Park is stepping down as ANOH President at the end of the year to be succeeded by Philip Hibbs (as an individual member of ANOH).

The ANOH event coincided with an Indonesian Industrial Hygiene Association (IOHA) board meeting. Norhazlina Mydin (Malaysia) is stepping down with Samantha Connell (Switzerland) elected as the next IOHA President.

The IIHA conference was attended in person by the Indonesian Minister for Industry and online by the Minister for Health, Minister for Manpower, and the Minister for Energy and Mineral Resources. Having four Ministers participate is a credit to the IIHA and its president, associate professor Mila Tejamaya from the University of Indonesia. University academics are highly regarded and regularly assist the government.

Since its inception in 2016, the IIHA has grown its membership to over 300 members and is currently seeking international recognition for its professional certification scheme.

The scientific program of the IIHA Conference spanned two and half days plus two days of professional development courses. Presentations covered the topics of COVID-19, climate change and WHS, chemical hazard management and regulation, PPE and psychosocial hazard management and regulation. Jacqueline Agius, WHS commissioner at WorkSafe ACT, addressed the latter.

The cultural context of WHS (the “Asian Way”) figured prominently. The informal sector in Indonesia is large (>50% of workers) and unregulated, with no provision for workers’ compensation. And this situation isn’t going to change any time soon. However, even poor workers have smartphones and access to social media, so technology has great potential to improve WHS awareness.

We expected world-leading hospitality, and we weren’t disappointed.

Meeting the Minister for Industry was a highlight for me. Alongside Dr Ismaniza Ismail (Izzie), I was delighted to be asked to give an unscheduled lecture to 40 Master of OHS students. The future for WHS in Indonesia looks bright – there were postgraduate OHS students from three universities (two Indonesian, one Malaysian) and several student helpers.

Mila Tejamaya’s son did a great job as MC (and part-time singer).

The 6th ANOH Annual Conference, organised by the Industrial Hygienist Association of the Philippines is in conjunction with the Asian Network of Occupational Hygiene. The venue is locked in: ANOH2023 will happen at the Acacia Hotel, Alabang, Metro Manila, Philippines, on August 26-30 2023.

Below is the updated conference flyer and call for papers which closes on May 12 2023. Please distribute these to any colleagues and relevant people in your network.

AIOH Foundation Update

Promoting the principles of occupational hygiene

It’s official – the AIOH Foundation has launched its grants program for 2023.

The first success story is the Cancer Council WA – you may be familiar with their work around silica dust. Their application to develop and deliver a program of initiatives relating to diesel engine exhaust got the go-ahead.

Cancer Council WA’s KNOW Workplace Cancer project will use the grant funding to build awareness of the health risks associated with diesel engine exhaust. This project will develop resources and run an online awareness campaign during National Safe Work Month 2023. The initiative seeks to engage stakeholders in improving current workplace standards for diesel engine exhaust.

Look out for updates – we’ll promote these initiatives as they launch.

Seize the opportunity

The Foundation is still accepting grant submissions. If you have a great piece of research or a project that meets our aim to reduce the incidence of workplace diseases –we want to hear about it.

And of course, if you want to help fund our work, please donate to The Foundation. Any amount (big or small), is gratefully accepted.

A lower asbestos exposure limit

As part of the Europe’s Beating Cancer Plan, European Union (EU) ministers of employment agreed their position on a proposal to tighten EU legislation protecting workers from the risks of asbestos. Their position is that the current occupational exposure limit (OEL) should be lowered to 0.01 f/mL as an eight-hour time-weighted average (TWA) and that asbestos fibre-counting should be carried out based on a more modern method (electron microscopy - EM). This “balanced approach” was said to be underpinned by a public health objective aiming at the necessary safe removal of asbestos.

Consequently, a Proposal for a DIRECTIVE OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL amending Directive 2009/148/ EC on the protection of workers from the risks related to exposure to asbestos at work has been published.

Before becoming law, the Council and the European Parliament need to agree on a joint position on the proposed revision. The Parliament is still in the process of defining its stance.

We (the authors) are of the opinion that such a reduction in the OEL is not justified for the following reasons:

1. The estimation of the risk of adverse health effects due to asbestos exposure (for example, mesothelioma and lung cancer) has been determined based on applying linear no-threshold (LNT) exposure‐response models. However, LNT risk extrapolation is being questioned in the peerreviewed literature as to its validity. Calabrese et al (2022) go further to say that LNT was made policy based on fraudulent research, manipulation of scientific literature and scientific misconduct by the US National Academy of Sciences.

2. There is mounting evidence that indicates there are protective mechanisms that can prevent carcinogenesis at low doses of genotoxic chemicals. Inflammation generally co-initiates cancer and transiently amplifies activated stem cells. Several non-genotoxic mechanisms have demonstrated threshold-shaped dose-response for cancer outcomes.

3. During the long latency period (typically 30-plus years) before the clinical diagnosis of cancer of the lung or of the larynx or diffuse malignant mesothelioma, genetic, chromosomal and epigenetic alterations occur. Recent biochemical studies have confirmed that oxidative damage to cytosine is a plausible biological mechanism leading to epigenetic alterations and development of cancer in association with persistent inflammation (IARC, 2012).

4. Various authors have suggested the existence of a chronic inflammation- driven threshold concentration of asbestos fibres that causes asbestos- related cancers. What that threshold concentration is, remains uncertain, but certainly, more than one fibre is required.

5. Even when using LNT exposure‐response models, there are difficulties in attempting to apply the dose-response data that does exist.

6. We believe that we are not seeing an increase in mesothelioma in Australia under current exposure scenarios. Due to the long latency period, most exposed workers in industries where asbestos exposure risk was high did not develop mesothelioma until decades later. The latest published data for Australia indicates a decrease in rates of mesothelima between 2013 and 2020 (AIHW, 2021). The asbestos mining and manufacturing industries in Australia have disappeared and exposures have been significantly less since the early 1990s. In addition, workers are now well protected with PPE and mandated work practices in asbestos removal, such that the working life exposure profile results in an extremely low cumulative exposure and subsequently extremely low risk of asbestos-related disease.

7. In terms of quantitative risk assessment, all the epidemiology studies used to determine risk are based on phase-contrast optical microscopy (PCM)/ membrane filter method (MFM) counts. PCM provides a relatively quick and cost-effective analysis of airborne asbestos samples, but it can’t distinguish between asbestos and non-asbestos fibres, nor differentiate between the different types of asbestos, and the MFM detection limit is at 0.01 f/mL. While electron microscopy (EM) can assess asbestos fibre exposure more accurately and has a lower detection limit, it is significantly more expensive and takes more time to analyse than a PCM sample. Most importantly, there is no simple relationship between results by PCM and EM counting methods. The ratio between PCM counts and EM counts varies considerably depending on fibre type and process/industry type and product type. The question that remains is, what EM-based OEL will be set as a PCM equivalent concentration?

8. In Australia, more than 90% of asbestos fibre monitoring is static sampling conducted for background, control and clearance monitoring for asbestos removal works and not for exposure risk assessment (R Golec & L Apthorpe, pers comm).

It seems somewhat academic whether the OEL is reduced to 0.01 f/mL as we should never be comparing these static monitoring results with an OEL in the first place as they were not taken in the breathing zone of workers. By default, we already use 0.01 f/mL as an action level which indicates the airborne fibre concentration is above the detection limit of the PCM method and control actions are required to be implemented.

The AIOH (2016) position paper on asbestos notes that the “AIOH believes that current exposure standards used in Australia are adequate and, as with any carcinogen, exposures should be maintained as low as reasonably practicable (ALARP).” We are unaware of any published evidence that suggests levels of exposure below 0.01 f/mL will provide significant reductions in ill health compared to the current limit of 0.1 f/mL, particularly when airborne concentrations above the PCM detection limit of 0.01 f/ ml require actions to control fibre concentrations. We believe that the 2016 AIOH position on asbestos is still relevant.

Whilst detection limits are improved with EM, it is impractical and expensive for most routine monitoring (that is, background, control and clearance monitoring) where quick results turnaround and reporting times are critical. The EM techniques can be used where lower detection limits are required and when identification of the fibre type in airborne samples is necessary.

A detailed technical paper has been prepared for distribution to AIOH members on this issue. It includes detailed analysis and references relating to the various aspects put forward supporting this opinion piece.

Past Conference Proceedings

A treasure trove of information

Past conferences: 2011, 2012, 2016, 2019

We have some exciting news – proceedings of the first 20 years of AIOH conferences are now available online. That’s two decades of valuable knowledge at the click of a button.

The AIOH has hosted conferences since 1982. These conferences have always provided a crucial platform for occupational hygienists, researchers and practitioners to share knowledge and insights on the latest developments in our field.

The proceedings of these conferences cover a wide range of topics, from exposure assessment and risk management to air sampling.

Having access to these proceedings is particularly useful for new members who may not have had the opportunity to attend the events in person (or were still in primary school).

This is also a highly-practical resource for researchers and students interested in the history and evolution of occupational hygiene practices within Australia.

If you’re an AIOH member – take advantage of the opportunity to access and learn from the bounty of expertise in these proceedings.

Go to the Conference section on the AIOH website, scroll down and start watching.

Lastly – sincere thanks to Noel Tresider AM for generously sharing his CD collection of conference proceedings. These helped facilitate this process.
