A message from the AIOH25 Scientific Chair
The development of the scientific program for AIOH25 has once again highlighted the depth and breadth of knowledge within our profession. This year’s theme, ‘Evolution, Insights into Impacts’, reflects the way occupational hygiene continues to adapt, innovate, and influence workplace health and safety in a rapidly changing world.
We were delighted to receive over 100 highquality abstracts from several countries, each contributing valuable perspectives on how our discipline is evolving and how these changes are impacting workers, businesses, industries, and communities. The submissions ranged across a diverse set of topics—from technological advances in sampling and data analysis, to emerging exposures, psychosocial risks, and innovative approaches to control
These contributions demonstrate not only the scientific rigour within our community but also the creativity in translating complex data into meaningful insights that can guide action. As always, our challenge is to take this knowledge beyond the technical and turn it into stories that resonate with decisionmakers, frontline workers, and the broader public.
The AIOH25 Scientific Sub-committee has worked tirelessly to review, assess, and shape these submissions into a compelling program which we are delighted to share Their dedication has ensured that the final selection reflects both excellence and
diversity, aligning strongly with our conference theme. We extend our sincere thanks to the sub-committee for their hard work, commitment, and expertise
New for AIOH25, we're excited to introduce a revamped poster presentation session. This initiative provides an additional platform for authors to showcase their work in a highly visual format, while also creating valuable opportunities to interact directly with delegates. Posters will encourage discussion, exchange of ideas, and allow presenters to receive feedback in a more informal and engaging setting, further strengthening connections across our community.
We also extend a heartfelt thank you to everyone who submitted an abstract Each contribution helps advance our profession and enriches the conversations that will take place during the conference Your willingness to share your research, case studies, and insights ensures that AIOH25 will once again be a rich learning experience for all.
Together, these efforts have created a program that not only showcases the evolution of our field but also provides critical insights into the real impacts of our work on people, workplaces, and society We look forward to hearing your stories and celebrating the continued growth of occupational hygiene at AIOH25

Gregor Riese of Giant Hygiene Services, delivered an informative presentation on Local Exhaust Ventilation (LEV) at the recent NSW AIOH state chapter meeting, 19 August. Gregor outlined what ‘good’ looks like in LEV performance testing, highlighting the importance of maintaining effective capture and transport velocity through hoods, passing smoke tests, and key design parameters for commissioning and installation.
Gregor also emphasised the need for safe filtration using HEPA or AS16890 filters, and the management of explosive dusts with ATEX-compliant filters and venting. His presentation reinforced that fit-forpurpose design is essential, with correct duct sizing, airflow, fan capacity, and noise levels maintained below 65 dB(A) and when you would need to contact a subject matter expert.
I would also like to extend thanks to the Australian Industry Group (AI Group) and fellow NSW Liaison Officers John Tiong and Shilpa Panyam, MAIOH, CProf for hosting and supporting this event.

AIOH Fundamentals of Dust
About this course
Dust occurs naturally and from man-made activities like driving on a dirt road or sawing a piece of timber. In most workplaces, dust is considered problematic and a hazard, especially as dust can impact your health. This course is designed to give you a fundamental level of knowledge and understanding of dust. You will learn what dust is, how to identify dust and the risks associated, the negative health effects of dust, and the controls use to manage the risks associated with dust.
AIOH Mould Cleaning for Cleaners
About this course
Mould is everywhere. It's a naturally occurring organism that plays an important role in nature's ecosystem. Low levels of mould can virtually be found everywhere, even in the most sterile rooms. Mould may grow indoors in wet or moist areas lacking adequate ventilation, including walls/ wallpaper, ceilings, bathroom tiles, carpets, insulation material and wood.
AIOH Mould Awareness
About this course
If moisture accumulates in a building mould growth will often occur. Mould affects people differently depending on their health and the type of mould. It can cause nasal and sinus congestion, hay fever, sore throats, headaches, eye irritations, body rashes and other aches and pains. Mould not only has the potential to cause health problems, but it can also cause damage to the buildings and surfaces it inhabits. AIOH's Mould Awareness online training module is designed to help learners identify mould, understand the conditions that can promote mould growth and develop an awareness of the steps for safely managing the presence of mould.
Breathe Freely Australia (BFA) aims to prevent dust-related occupational lung disease, such as silicosis, in workers, through education & awareness of safe work practices to control exposures.

Hedyeh Albokhamis is a Health, Safety, and Environment (HSE) professional with over six years of experience in high-risk industries. She is currently completing a Master of Public Health at Edith Cowan University, expanding her knowledge in health promotion and public health Although already an experienced specialist, Hedyeh undertook an internship with Transdev Western Australia in the Health and Safety unit to gain a deeper understanding of workplace health and safety legislation in Australia.
Hedyeh’s expertise includes integrated safety and health management, compliance, risk assessment, and the application of ISO standards. She is particularly interested in musculoskeletal disorder prevention, respiratory health, and proactive strategies to prevent incidents. Hedyeh is passionate about combining public health principles with safety management to create safer and healthier workplaces
Integrating workplace Safety compliance procedures with broader occupational hygiene and wellness programs is no longer a luxury; it is an operational imperative. In today’s high-risk industries, safety controls based solely on compliance are not enough to keep workers safe Health, hygiene, and safety hazards sometimes overlap. For instance, an employee with unmanaged musculoskeletal discomfort is more likely to have incidents linked to exhaustion, and psychosocial stress might make it harder for the employee to be aware of what is going on, leading to more mistakes
The Australian Work Health and Safety Strategy 20232033 makes this integration a national priority. It suggests that combining safety requirements, such as identifying and mitigating hazards with proactive health and well-being programs that focus on physical fitness, mental health and preventing chronic diseases not only lowers injury rates but also boosts productivity and workforce participation. According to Safe Work Australia, companies that use this dual approach see measurable drops in lost time injury frequency rate (LTIFR) and compensation claims, as well as healthier, more engaged workers.
Evidence from Australia
The Institute for Safety, Compensation, and Recovery Research (ISCRR) looked at workplaces in Victoria and found that combining safety compliance with promoting hygiene and well-being had clear benefits.
Their assessment showed that many organisations’ programs blended regulatory safety controls, like managing hazards and following PPE rules, with health and hygiene focused programs such as redesigning workspaces and providing nutritional support. This integration resulted in diminished injury rates and enhanced employee well-being
In one pilot program, AMP Group Australia added psychological health risk management to their WHS plan, which resulted in a significant shift in culture. AMP ensured that their compliance policies aligned with best practice well-being tools like FlourishDx, which meant that employees felt more comfortable raising concerns, and leaders were better able to respond. This led to fewer serious health and safety incidents and reduced turnover.
Safety, health, and hygiene work well together
Occupational hygiene, health and wellness programs often address risks that build up over time, such as respiratory diseases, musculoskeletal disorders, and mental health issues. Occupational Safety compliance, on the other hand, focuses on preventing short term, serious incidents, like falls from height, equipment malfunctions, and chemical spills Managing these areas separately could result in important issues being missed, however, combining them allows for holistic worker protection.
For instance, according to a Herald Sun report after the unexpected death of employee Adam Butterworth, who suffered a sudden heart attack on-site, Incat Tasmania started offering free cardiovascular health checkups on-site. Three employees with dangerously high blood pressure were identified and referred for immediate treatment (within two weeks) This treatment likely included professional diagnostic assessment (such as ECG and blood tests), direct hospital referral for clinical follow up, lifestyle interventions, and potentially antihypertensive medication, all aimed at rapidly reducing their cardiovascular risk
The 15-minutes challenge, developed by the University of South Australia, urged employees to commit to a short burst of activity every day. More than 11,000 Australian workers saw measurable improvements in their energy, mood, and overall fitness. These examples show that when safety and health measures are combined, companies can address both short-term and long-term health, making their workers more resilient.
When Safety Meets Health: COVID-19’s Dual Impact on Australia’s Workforce
The COVID-19 pandemic did not just disrupt workplaces; it redefined the way we understand the relationship between safety and health. What had often been treated as parallel streams suddenly had to merge into a single, coordinated strategy. In those high-pressure months, integration was no longer an ideal, it was a survival mechanism.
On the safety front, measures like PPE mandates, strict physical distancing and sterilization of equipment and surfaces were implemented (WHO). On the health side, employers rolled out on-site vaccination clinics, implemented regular nasal and throat swabs for early detection, tracked workforce wellness, and provided ongoing support for employees experiencing Long COVID symptoms, ensuring both quicker recovery and reduced reinfection rates In critical sectors such as manufacturing and logistics, this combined approach proved decisive
Without it, the sudden absence of a single skilled operator due to illness could idle an entire production line. That either meant halting operations completely or relying on less experienced staff in high-risk roles, both scenarios increasing the likelihood of incidents and operational losses.
Without it, the sudden absence of a single skilled operator due to illness could idle an entire production line. That either means halting operations completely or relying on less experienced staff in high-risk roles, both scenarios increasing the likelihood of incidents and operational losses
The figures are compelling: research from the University of Melbourne, ANU, and UNSW revealed that Australians with Long COVID led to average of 100 million lost labour hours in 2022, costing the economy approximately AUD $9.6 billion, equivalent to about one-quarter of Australia’s real GDP growth that year.
These statics clearly show that failing to integrate safety and health is not just a matter of risk, it is a serious economic liability. In contrast, workplaces that synchronised immediate infection control with long-term health strategies were better able to sustain operations, protect workers, and preserve productivity.
When safety meets hygiene: Silica dust management
Workers in a range of industries, including construction, mining, and manufacturing may be exposed to respirable crystalline silica a fine dust that can cause silicosis, lung cancer, and other serious diseases. In Australia, it is estimated that over 600,000 workers are exposed to silica dust annually, with silicosis emerging as growing health crisis The risk to workers is both acute (e g dust explosions) and chronic (e g long-term respiratory illness).
In mining, occupational hygiene monitors invisible hazards like silica dust through air sampling, health surveillance, and exposure limits, while workplace safety enforces visible controls like PPE, ventilation, and emergency protocols. Together, they reduce both chronic health risks and acute dangers by layering environmental, behavioral, and procedural protections, and dealing with different dimensions of risk. This integrated approach ensures workers are safeguarded from long-term illness and immediate harm, creating a safer, healthier work environment.
The integration of hygiene and safety is not just about compliance; it is a proactive and ethical means of managing risk that values worker safety and wellbeing.
Bringing together workplace health, safety and hygiene
When Safety prevents the sudden, and health and hygiene shield against the unseen, integration becomes the bridge to resilience Safety prevents the accidents you can see, and hygiene protects against the risks you cannot. Together, they ensure that the future of work is not only safer, but also stronger, where every worker goes home not just protected, but empowered to thrive

A Global Spotlight on Heat Stress
When four young university students from the United States found themselves presenting at the International Labour Organisation’s Youth Congress during Expo 2025 in Osaka, Japan, they carried with them more than research. They brought fresh perspectives, global empathy, and a resourceful approach to one of the most pressing workplace hazards of our time: heat stress.
The team, Jonah Lindsay, Kaylee Packer, Brinley Openshaw, and Parker Willis, first connected through their shared studies at Brigham Young University.
Today, they represent a new generation of occupational hygienists spanning institutions across Utah and Michigan. Each brings their own passion: Jonah’s love of writing and music, Kaylee’s focus on vulnerable populations, Brin’s drive to connect occupational health with the medical field, and Parker’s quiet but practical energy for finding solutions that empower workers.
From Idea to Osaka - A Journey of Discovery
Their path to Osaka was far from linear. Initially focused on migrant worker conditions broadly, they soon realised their project did not quite align with the scope of the congress. Rather than discard their passion for vulnerable populations, they sharpened their focus.
“As we thought about industries where migrant workers are most often employed such as agriculture, construction, and roadwork, it became clear,” recalls Parker. “Heat stress was the common hazard, one that is only intensifying in a warming world.”
What followed was a whirlwind of research. The team dove into global literature, consulted with professors, and uncovered how underrepresented groups were disproportionately affected by heat stress. They realised that much of the existing science relied on a “one-size-fits-all” approach, often based on a 70-kilogram male worker, leaving significant gaps in protection for others.
“As I began to see how these vulnerable populations were being overlooked, I felt strongly that we had to focus on them,” says Kaylee. “Equity in worker safety means recognising that not everyone faces the same risks in the same way.”
The Innovation - Personalised Protection in the Palm of a Hand
Out of this realisation came their solution: a mobile app designed for everyday workers, with no technical knowledge required. The app would integrate real-time weather data, humidity, and heat indices, while also accounting for individual factors such as body size, gender, clothing, and workload. It would then provide personalised alerts such as rest breaks, hydration reminders, or finding shade, delivered in plain, accessible language.
The students also looked for ways to encourage engagement. Inspired by modern media, they designed the app to use “streak psychology,” encouraging workers to build healthy habits in the same way popular social apps do. Employers could also incentivise safe practices, fostering cultures of prevention rather than reaction.
“We wanted something higher up the hierarchy of controls,” explains Brin. “Rather than just PPE solutions like cooling vests, we aimed for an administrative intervention that gives workers autonomy over their own health.”
Collaboration, Not Competition
One of the biggest lessons they took home from Japan was the power of collaboration. While they discovered that professional associations such as AIHA already had heat stress apps, they reframed their project not as a competitor but as a complement.
“At first we were a little disappointed,” admits Jonah. “But then we realised it was an opportunity. We could contribute to making these tools more inclusive, more multilingual, and more tailored to vulnerable groups.”
This perspective reflects the team’s broader philosophy: occupational hygiene is not a solitary pursuit but a collective mission. By partnering with professionals and existing organisations, they see the potential to bring their idea from student concept to global solution.
Looking Ahead- Youth, Innovation, and Impact
The Osaka congress was more than a milestone for these students. It was a signal for the profession. It showed how youth voices, unburdened by traditional frameworks, can spot overlooked gaps and propose creative, people-centred solutions.
Their next steps involve exploring collaborations with professional associations, refining the science behind individualised heat stress calculations, and seeking guidance from occupational hygienists worldwide. Most importantly, they are calling on the profession to provide mentorship and feedback.
“We are students,” Parker acknowledges. “We do not yet have the credentials to make these claims alone, but we are eager to learn, and we know that with the support of professionals, this idea could save lives.”
A Global Call
As Australia braces for hotter summers and the world reckons with climate change, the urgency of heat stress prevention is undeniable. What this team has shown is that innovation does not only come from labs or boardrooms. It also comes from 3am ideas, from spirited debates in desert heat, and from students daring to imagine better futures.
In their words: “It’s about putting health back in the hands of workers.”

What’s in a Name?
UNPO
How often do you get those quizzical looks at social functions when they ask you “What do you do?” and you reply “I’m an Occupational Hygienist.”? What about “don’t you get tired of telling people to wash their hands?” My pet hate is when you have to bite your lip listening to those insufferable jokes about cleaning toilets, and let’s not forget about the dental hygiene comments. I heard of one human resources department when questioned about recruitment, did not know there was a difference between occupational hygienists and occupational therapists.
Whilst the title does literally mean occupational health (hygiene derives from Hygieia, the Greek goddess of health) I still believe our title does not reflect what we do nor help us to explain our profession. This is not a new dilemma, there have been numerous attempts over the years in our profession across the world to resolve this issue. Some traditionalists dig their heels in and say it’s not about the name it’s how we promote our profession. This may be true to some extent, but it is definitely not helpful.
In 2017 the Annals of Occupational Hygiene changed its name to Annals of Work Exposures and Health, chosen to make the journal’s scope more relevant and to support the more expansive view of the concepts of work, exposures and health. Maybe it is time we seriously think about doing something similar.
It’s time for a change. Agree or disagree? What are your thoughts and suggestions?

NEW MODEL CODE OF PRACTICE TO MANAGE RISKS OF SILICA DUST IN THE WORKPLACE
Safe Work Australia has published a new model Code of Practice for managing risks of respirable crystalline silica in the workplace to help protect workers from silica.
Breathing in respirable crystalline silica (silica dust) can cause serious health conditions like silicosis and lung cancer. Silica dust is generated when processing material containing silica, such as cutting, sanding or polishing. All silica-related diseases are preventable by eliminating or minimising exposure to silica dust.
The model Code of Practice gives employers practical information on how to comply with the WHS Regulations to manage risks of silica dust to protect workers and others.
PEOPLE WHO WORK WITH OR NEAR LIVESTOCK ARE BEING WARNED OF THE DANGERS OF Q FEVER AHEAD OF THE SPRING AND SUMMER PEAK.
Q fever is an infection caused by Coxiella burnetii, a type of bacterium found worldwide except New Zealand. The infection is almost always related to direct or indirect contact with animals such as cattle, sheep, or goats, although a wide range of animals including cats, dogs, and kangaroos may carry the infection.
There have been 18 cases of Q fever reported to SA Health this year to date. There were 23 cases reported in 2024, and 21 cases in 2023.
Welding is a common activity in many Australian workplaces, but it comes with serious health risks Workers can be exposed to cancer-causing agents such as welding fumes and ultraviolet (UV) radiation from the welding arc. Recent research shows that over 90% of welders in Australia are exposed to welding fume, yet the use of effective control measures remains poor.

Transition to the new respiratory protection standards – ISO Respiratory Protection Devices (RPD Standards)
For years, Australian and New Zealand workplaces have relied on two key standards for respiratory protection:
AS/NZS 1715: Selection, use and maintenance of respiratory protective equipment
AS/NZS 1716: Respiratory protective devices
Overtime, the contents of these standards have become outdated. Advances in fit testing technology, modernisation of respirator testing techniques and a greater understanding of wearer factors.
Since 2015, the Standards Australia SF-010 Respiratory Protection Technical Committee, currently chaired by AIOH member Mark Reggers, have been adopting ISO standards. With the full suite of ISO standards now adopted by the SF-10 committee, the transition period has begun.
What are the benefits of the change?
The key benefits of the change include:
Harmonisation of global standards
Standardised terminology and definitions
Moving from performance of the respirator by design to performance required by the wearer –a human centric approach.
Greater consideration of the burden of RPD upon the wearer- including intensity of work and other individual factors.
Respirator classification on performance rather than ‘type’ – incentivising manufacturers to further improve products.
Though greater in number, the detail and clarity within the new standards reduce grey area and interpretation from the user – promoting best practice selection, use and maintenance of RPE across all industries.
The AS/NZS ISO Standards are a wider range of primarily shorter, detailed standards as compared to the current broad standards
Current Standard
AS/NZS 1715:2009 - Selection, use and maintenance of respiratory protective equipment
New AS/NZS ISO Respiratory Standards & Technical Specifications
AS/NZS TS ISO 16975.1:2023
Selection, use and maintenance – Part 1: Establishing and implementing a respiratory protective device
AS/NZS ISO 16975.3:2023
Selection, use and maintenance – Part 3: Fittesting procedures
AS/NZS TS ISO 16975.2:2023
Selection, use and maintenance – Part 2: Condensed guide to establishing and implementing a respiratory protective device
AS/NZS ISO 16975.4:2024
Selection, use and maintenance – Part 4: Selection and usage guideline for respiratory protective devices under pandemic/epidemic/outbreak of infectious respiratory disease
Current Standard
AS/NZS 1716:2009 - Respiratory protective devices
New AS/NZS ISO Respiratory Standards & Technical Specifications
AS/NZS ISO 16976.1:2024 Respiratory Flowrate
AS/NZS ISO 16976.3:2024 Physiological Limitations
AS/NZS ISO 16976.5:2024 Thermal Effects
AS/NZS ISO 16976.7:2024 Hearing and Speech
AS/NZS ISO 16976.2:2024 Anthropometrics
AS/NZS ISO 16976.4:2024 Work of Breathing
AS/NZS ISO 16976.6:2024 Psycho-physiological
AS/NZS ISO 16976.8:2024 Ergonomics Factors
There are also a range of standards – the AS/NZS ISO 17420 and AS/NZS ISO 16900 series –which are relevant to mask manufacturers. These standards address a wide range of performance benchmarks and testing requirements that must be met.
Is there a transition period to the new standards?
Yes. The transition period is current as the new standards have been adopted. The existing and adopted AS/NZS ISO standards will run in parallel unto 2030 – where the existing standards will be superseded.
The five year transition period is designed to allow regulators, manufacturers and users to adapt their current practices as required.
The SF-010 committee will continue to monitor the transition period – with the supersede date of 2030 to be reviewed in 2028 to assess practicability.
Does my current respiratory protection still meet the requirements?
Yes. Until such time as the current standards are officially superseded, it is acceptable to use RPE on site provided the requirements of AS/NZS1715 and AS/NZS 1716 are met.
Manufacturers will be required to update references and provide details on the classification of products as per the AS/NZS ISO standards. Workplaces will need to be aware of the new classification scheme for RPE to ensure they are selecting the appropriate RPE as manufacturers begin the transition.
What will change with respirator and filter classification?
The most visible and significant day to day change for and Occupational Hygienists and OHS professionals will be the respirator classifications.
The greater focus on human factors within the AS/NZS ISO standards are reflected in the classification scheme – with workplaces required to have a thorough understanding of employees ‘work rate’ as part of the selection criteria.
The following table summarises changes from the current AS/NZS standards to the AS/NZS ISO
Current AS/NZS Standards
AS/NZS ISO Standards
Total Inward Leakage (TIL) Lab Test
Basic Classification
Work Rates
Particle Filters
Gas and Vapour
Selection and Use
Type
(i.e half face with a P2)
Not Classified
3 categories - P1, P2, P3
Classified by capacity (AUS, Class 1, Class 2, Class 3)
Based on Required Minimum Protection Factor
(i.e how the individual product or combination of respirator and filter perform)
4 work rate classes W1, W2, W3, W4
Up to 20
(Four work classes and five efficiencies – F1, F2, F3, F4, F5)
Classified by capacity and work rate for wider range of gas/vapour classes
Based on ISO Classification –Protection level linked to TIL –Work Rates
Protection Class
One of the most significant changes is the move to Protection Level for each individual product based on it’s performance in the TIL test and assigned protection class (PC). This protection level is essentially the new ‘Assigned Protection Factor (AP)’ of the respirator.
Under the AS/NZS ISO system, a respirator can theoretically achieve the highest or lowest protection class regardless of type – as the result is based purely off the laboratory TIL test.
Further real world validation of the protection levels will be occurring – with the SF-010 committee continuing discussions around the final Protection Levels adopted.
Work Rates
The AS/NZS ISO standards places a greater emphasis on the effectiveness of RPE at various ‘work rates’. Respirator manufacturers will be required to test products to a ‘Work Rate Class’, whilst those selecting RPE must have a thorough understanding of employees work rates to determine which class is appropriate for the work process.
Work Rate Class Breathing Rates
W1
Moderate 35 l/min and lower
W2
Very Heavy 65 l/min and lower
W3
Extremely Heavy 105 l/min and lower
W4
Maximal 135 l/min and lower
Workplace Examples
Average for full work shifts including breaks light manual work (writing, typing) hand and arm work (small bench tools, inspection, To:
Sustained hand and arm work (hammering) arm and leg work (off-road operation of lorries);
Average for full work shifts including breaks Intense arm and trunk work carrying heavy material, shovelling, sledgehammer work, sawing, planning or chiselling hard wood, To:
Very intense activity at fast pace shovelling or digging, climbing stairs walking at a speed greater than 5,5 km/h
Continuous work for up to 2 h without breaks
Safety and rescue work with heavy equipment fit individuals pacing themselves at 50 % - 60 % of their maximal aerobic capacity; To:
· Continuous work for up to 15 min without breaks Rescue and fire-fighting work at high intensity;
· fit and well-trained individuals pacing themselves at 70 % to 80 % of their maximal aerobic capacity;
Continuous work for less than 5 min without breaks Rescue and firefighting work at maximal intensity;
· fit and well-trained individuals pacing themselves at 80 % to 90 % of their maximal physical work capacity;
Essentially, an organisation must determine the work rates of workers in order to appropriately select RPE.
Respiratory Interface
The respiratory interface (RI) of the RPE will also be displayed on products, providing clarity with respect to the style of the RPE.
more than head, up to complete body
more than head, up to complete body
Filter Efficiency
There are significant changes to the terminology and labelling of filters based on their various efficiencies. Key changes are as follows:
The P1, P2 & P3 particle efficiency system is replaced. The colour coding system for filter types is replaced Particle filters will remain white, gas/vapour filters will be blue.
There will be individual special application classes-including for firefighting, welding, abrasive blasting, escape, mining and others.
The following table summarises the filter classification system under the AS/NZS ISO standards (excluding special applications):
What will the classification look like?
Assume the following is true for a respirator
1. A filtering facepiece protecting the wearer against harmful particles
2. Total inward leakage of < 20%
3. Validated for ISO work rate 1 4. Minimum filter efficiency of 99%.
Under the AS/NZS ISO standards, the following classifications are met based the design and performance criteria.
Therefore, the RPE would be classed as: PC1 W1 bT F3.

As the world of work continues to evolve, so too does the vital role of occupational hygiene in safeguarding worker health and wellbeing. Across the globe, leading organisations are stepping up with fresh ideas, bold initiatives, and collaborative efforts that reflect the dynamic challenges of our time. These updates provide a snapshot of the international occupational hygiene community in action, advocating, innovating, and championing health where it matters most: at work.
International Occupational Hygiene Association (IOHA)
The latest issue of The Global Exposure Manager is out! In this edition, Dr Sharann Johnson provides an update from the National Accreditation Recognition Committee There’s also a highlight on Dr Ross Di Corleto’s webinar about heat stress, which included insights into using the AIHA Heat Stress App, a handy tool for understanding risks in hot environments.
Coming up: On Wednesday, October 22nd (10:30 pm AEDT), Alex Wilson and Samantha Connell will present a webinar on Soft Skills to Support Occupational Hygiene Technical Skills This session explores how strong communication and leadership skills can boost your effectiveness as a future professional. Register here Soft Skills to support Occupational Hygiene Technical Skills
British Occupational Hygiene Society (BOHS)
The BOHS recently responded to the ‘Call for Evidence on a Men’s Health Strategy’ stressing that workplace exposures remain a critical but often overlooked factor in men’s health outcomes. Alarmingly, poor workplace management contributes to more than 800,000 preventable cases of ill health each year, including 12,000 respiratory-related deaths.
Meanwhile, the BOHS is conducting an important Isocyanate Exposure Study Isocyanates, commonly found in paints, foams, and adhesives, can pose serious risks if not properly controlled. Because these exposures must be measured using the regulated MDHS 25/4 method, only licensed professionals can perform the assessments. With support from the Faculty of Occupational Hygiene, BOHS is building a database of exposure data, which could provide valuable insights for future health protection strategies
Date/Time: October 22, 2025 – 7:30am to 9am EDT; 12:30pm to 2pm BST; 7:30pm to 9pm AWST
Fees: Complimentary to all members of IOHA Associations. (IOHA is a not-for-profit organization so please consider donating through the QR code below if you are not a member or from a for-profit industry).
£80 for industry-sponsored and for-profit organization participants.
American Industrial Hygiene Association (AIHA)
Across the Atlantic, the AIHA is ramping up advocacy efforts to protect essential health and safety agencies in the U S Ongoing budget cuts are threatening the work of NIOSH (National Institute for Occupational Safety and Health) and the Chemical Safety and Hazard Investigation Board (CSB) amongst ongoing budget cuts which would severely limit or remove these organisations functions.
On a positive note, the AIHA Heat Stress App V2 has just been updated! The new version now includes guidance for indoor workers, making it a more comprehensive tool for managing heat risks. It’s available on both iPhone and Android.
Further articles about works being undertaken can be found in the News section of the AIHA with reports by NIOSH on Lead Exposures to Telecommunications Workers and Blatstomycosis outbreak at a paper mill, EPA rulings on chemical safety and new CSB investigation summaries.
