Silicosis in retrospect is an overview of the year of 2021 with regards to silicosis related news, legislative changes, cases that were reported in the news, legal battles, national reports, technological advancement in monitoring and surveillance of silicosis amongst many other silicoses related news in Australia. Global Road Technology gives you 2021, January to December overview of silicosis in retrospect.
Crystalline silica, also known as quartz, is a natural component of sand and granite that is commonly found in construction materials. Exposure to crystalline silica dust can cause silicosis, a lung disease where scar tissue forms and reduces lung function. Construction workers are at risk of exposure during activities like sandblasting, jackhammering, cutting concrete, and tunneling. OSHA has regulations to limit crystalline silica exposure and requires employers to provide protective equipment and engineering controls to prevent workers from breathing in harmful silica dust.
Global Road Technology are silica dust control specialists servicing the mining, construction, renewables, quarrying and oil and gas industries. Dealing with silica dust at its source takes specific understanding of the particle size of silica dust in relation to the dust control product used. GRT has a range of different silica dust control products that can be utilized during activities such as drill and blast, tunneling, underground mining, stockpiling, transportation, haul roads, conveyor belt and transfer points amongst many other areas of application. Silica dust related terminology can be very confusing! There are must-know terms related to silica dust and these often find themselves being interchanged or misplaced in the thick of things.
Global Road Technology is a specialist in silica dust control serving various industries. They define the top 10 terms related to silica dust, which include crystalline silica, silica dust, and silicosis. Crystalline silica is a naturally occurring mineral composed of silicon and oxygen that can be found in rocks. Silica dust is generated from stone containing silica during processes like cutting and drilling. Silicosis is a group of lung diseases caused by exposure to silica dust, which can have acute, accelerated, or chronic forms.
The new OSHA standard aims to protect workers from respirable crystalline silica, a component of materials like sand and concrete that can cause serious lung diseases when inhaled. The standard requires employers to limit worker exposure to silica and implement certain safety measures by deadlines in 2017 and 2018.

Exposure to silica dust can increase the risks of silicosis and lung cancerCarolyn_Pope
Every day, thousands of Australian workers face different types of occupational hazards. The most common reasons for injuries and death include vehicle accidents and slips and falls. In some cases, however, the causes are so small to even matter in the beginning. What is worse is it can take several years before the symptoms manifest. By then, the disease may already become difficult to treat or incurable. A good example is exposure to silica dust.

Silicosis. Ifs a disabling and often
fatal disease that can strike land-
scape cjie;^ members, even those
laridscáplé^l
unaware of the hazards of crystalline
silica dust and how to protect their
workers.
Silicosis, which often has no symp-
toms in its early stages, develops as a
result of inhaling dust containing tiny
particles of crystalline silica. Crystalline
silica, which is a major part of the
earth's crust, can be found in many
materials at landscape construction
sites. Among these are soil, sand, brick,
block, mortar and concrete. Other
materials containing silica that may be
present at general construction sites
where your crews are working include
cement board, roofing aggregate, and
some drywall joint compounds.
Although there is no
cure for silicosis, there
are steps landscape
contractors and crew
members can take
to reduce the risk of
developing this disease.
Your crew members may be breath-
ing in harmful silica dust and not even
know it. That's because the small parti-
cles of crystalline silica that get into the
air are often not visible—and it can take
20 years or longer for the chronic form
of silicosis to develop. In the meantime,
though, as a crew member inhales the
dust, silica particles can scar the lungs,
causing the disabling, irreversible and
incurable lung disease called silicosis.
The presence of silica in the lungs
can also weaken the body's ability to
fight infections, so infectious illnesses
such as pulmonary tuberculosis can
lung cancer and chronic obstructive
pulmonary disease, and may be related
to kidney disease and other adverse
health effects.
Silicosis is a progressive disease, so
removing a worker from the job does
not stop its progression. As silicosis
progresses, symptoms may include
severe cough, chest pains, weight loss,
fever, weakness, night sweats, short-
ness of breath, respiratory failure and/or
death. (See "Resources for Employers"

Silica is a mineral found in many materials like glass and sand. Repeated exposure to crystalline silica dust can cause serious illnesses like silicosis and lung cancer. Employers must implement controls like ventilation, work practices, hygiene facilities and monitoring to limit worker exposure and comply with regulatory limits. A complete silica control program uses engineering, administrative and personal protective equipment controls along with air monitoring, training and medical surveillance.
This document provides health and safety advice for stonemasons regarding silica dust. It discusses how respirable crystalline silica (RCS) is found in many types of rock and stone. Exposure to RCS dust particles can lead to serious lung diseases like silicosis and lung cancer. The highest risk is from freshly fractured fine RCS particles generated during tasks like drilling, cutting, and grinding. The current workplace exposure limit for RCS is 0.1mg/m3. Control methods include suppressing, collecting, and containing dust through techniques like water sprays, ventilation, and encapsulation. Respiratory protective equipment is also important but should only be used as a last resort. Maintaining controls and conducting

Domestic hygiene focuses on maintaining cleanliness and sanitation in households, while industrial hygiene aims to prevent occupational hazards in workplaces like construction sites. Industrial hygiene involves assessing, preventing, and controlling hazards from noise, dust, chemicals, and other agents that can cause injury, illness or disease. It requires specialized knowledge to identify risks and implement controls using sophisticated equipment and techniques. Both domestic and industrial hygiene are important for environmental engineering and public health.
Scientific Evidence of Health Effects from Coal Use in Energy Generationjundumaug1
Coal combustion for energy generation produces air pollutants that negatively impact human health. Particulate matter, sulfur dioxide, and nitrogen oxides from coal-fired power plants cause respiratory effects like decreased lung function and increased illness. Long-term exposure to particulate matter also increases risk of lung cancer. Coal combustion also contributes to cardiovascular and neurologic disease as well as low birth weight and preterm births. An estimated 210,000 deaths and over 2 million illnesses occur annually worldwide due to health effects of air pollution from coal-fired power plants.
Mining is considered as a difficult and harmful job as it is done in a very
difficult physical and environmental condition. In addition to that, miners are exposed
to the dangers, damages and even death because of the bad condition of mines. The
dangers of mines are different in accordance with the kind of mine which may be
underground or surfaces. The dangers may be a bit different in different cities and
mines. Main harmful factors in mining are the physical damages, hyperthermia,
hearing loss, lung diseases, musculoskeletal diseases and facing with dangerous gases
and beams. The purpose of this essay is to examine the effect of physical, chemical
and biological harmful factor on miners. This survey has adopted descriptive method
and data are collected by library method. The results showed that the exposure of
chemical factors such as dust, methane and silica, and physical factors such as noise,
radiation, and biological factors may have great danger for miners.
1) The document discusses a study on incorporating visible light activated titanium dioxide (TiO2) nanoparticles into denture base resin to improve oral health.
2) In vitro tests found that denture base resin containing 3-5% TiO2 nanoparticles exposed to visible light significantly reduced colony forming units of common oral pathogens over time.
3) Preliminary in vivo tests also saw reduced bacterial plaque buildup on dentures containing TiO2 after 6 months of use, suggesting the nanoparticles maintain antimicrobial activity long-term.
The document discusses the environmental and health impacts of mine dust pollution. It notes that research has shown mining activities release dust particles into the air, water, and land that can negatively impact the health of mine workers and nearby residents. Mine dust pollution is a significant environmental concern as it can reduce vegetation and air quality. It is also a major occupational health hazard for mine workers as it can lead to respiratory diseases. The pollutants in mine dust also pose risks to public health as they may contaminate surrounding areas impacting domestic water and food security for nearby residents. Further research is still needed to fully understand the health effects of mine dust exposure.
This document discusses the use of metal nanoparticles as coatings on dentures to improve denture hygiene and reduce microbial adhesion and counts. It notes that poor denture hygiene in elderly patients can lead to health issues like aspiration pneumonia. Nanoparticles of titanium dioxide and aluminum oxide are proposed as coatings as they have shown antimicrobial properties in other applications. Specifically, titanium dioxide coatings have been found to inhibit adhesion of streptococcus sanguinus and candida albicans biofilms on dentures. Aluminum oxide nanoparticles have also been shown to inhibit growth of staphylococcus aureus bacteria. This study aims to investigate these two metal nanoparticle coatings on denture resin to examine their effects on reducing plaque
The document discusses two disciplines - organizational leadership and health professions - and how they relate to the oil and gas industry. It focuses on how organizational leadership is important for ensuring work is done correctly and safely. Health professions help protect worker and environmental safety, which is heavily regulated in the industry, particularly around issues like silica dust exposure and hydraulic fracturing. The goal of companies is to conduct extraction in a way that does not harm workers, the environment, or wildlife.
The document discusses the health and safety regulations for fracking in the UK. It states that the overriding objective of regulations is to ensure public safety for those near fracking activities as well as for workers. It outlines that before fracking can commence, operators must obtain licenses, negotiate land access, submit well plans to the HSE, and submit fracturing plans to DECC. Regular reporting to the HSE is also required during the operational phase to ensure well integrity is maintained. The document emphasizes that fracking can proceed safely if operations are carried out according to regulations with help from specialized legal advisors.
This presentation discusses OSHA's respirable crystalline silica standard 29 CFR 1910.1053. It was created by the North Carolina Department of Labor for safety training. It covers topics such as the new permissible exposure limit, definitions, compliance methods, exposure assessment, regulated areas, dates of implementation, and record keeping requirements. The standard applies to occupational exposures from dust generating activities involving materials that contain crystalline silica, such as quartz, unless objective data shows exposures will be below 25 μg/m3 or the employer complies with the construction standard.
The document discusses how silica nanoparticles (SiNP) can induce protein citrullination in lung cells. It summarizes previous research showing nanoparticles may cause autoimmune diseases by inducing protein citrullination. The study aims to investigate if SiNP-induced protein citrullination in lung cells is persistent after removing the SiNP. The researchers exposed lung cancer cells to SiNP and analyzed protein citrullination over time using high content screening and western blotting. They found SiNP significantly increased protein citrullination compared to untreated cells, and this increase persisted for up to 96 hours after removing the SiNP. This suggests SiNP-induced protein citrullination is irreversible and could explain harmful effects like

This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

- High levels of silica exposure are common in many parts of India and can cause respiratory diseases like bronchitis, pneumoconiosis, and silicosis. These diseases often go undiagnosed and are difficult to treat.
- Modern medicine has not found effective treatments for silica-induced diseases. However, an Ayurvedic formulation called Kamadgiri was found to significantly reduce cough and

An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Rainfall intensity duration frequency curve statistical analysis and modeling...bijceesjournal
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

1. Silicosis in retrospect – A 2021 Overview
Silicosis has been making headlines in 2021. This aggressive and deadly form of lung diseases
has different types namely; acute, accelerated and chronic silicosis. It is caused by exposure to
respirable and inhalable silica dust that is carcinogenic and lodges in the deep parts of the lungs
and destroys the normal functioning of the pulmonary system which is often fatal. Silicosis in
retrospect is an overview of the year of 2021 with regards to silicosis related news, legislative
changes, cases that were reported in the news, legal battles, national reports, technological
advancement in monitoring and surveillance of silicosis amongst many other silicosis related
news in Australia. Global Road Technology gives you a 2021, January to December overview
of silicosis in retrospect.
January
WorkSafe Victoria (WorkSafe), on behalf of the Victorian Government, is proposing to
strengthen the regulatory regime to better protect workers from exposure to respirable
crystalline silica by developing long-term crystalline silica regulations. The proposed
Occupational Health and Safety Amendment (Crystalline Silica) Regulations 2021 (proposed
Regulations) aim to improve risk assessment and information relating to the control measures
for reducing exposure to respirable crystalline silica dust. It will also maintain a ban on
uncontrolled dry-cutting of engineered stone and retains the ban on dry cutting of engineered
stone only, and includes a licensing system for workplaces that use engineered stone. As part
of this review, Deloitte Access Economics (Deloitte) was engaged by the Victorian
Government to develop a Regulatory Impact Statement (RIS) to provide an independent
assessment of the proposed Regulations. The RIS sets out the objectives of the proposed
Regulations, explains their effect and assesses the nature and scope of the problem that the
proposed Regulations seek to address. The proposed Regulations and associated Regulatory
Impact Statement (RIS) were released for public comment on 22 January 2021.
The McGowan Government has made an important change to the Occupational Safety and
Health Regulations 1996 that will increase protections for workers exposed to respirable
crystalline silica in the engineered stone industry. As from today, with a three-month grace
period, employers will be required to provide a low-dose high-resolution computed
tomography (HRCT) scan, supervised by an appointed medical practitioner, instead of the
previously required chest X-ray. HRCT scans are superior to chest X-rays and will assist in the
early detection of silicosis. Silicosis is a serious and potentially lethal occupational lung disease
caused by exposure to respirable crystalline silica in industries such as engineered stone
product manufacturing, installation, stonemasonry and construction work. The amendment will
assist in the early detection of silicosis and follows the McGowan Government's recent decision
to halve the workplace exposure standard for respirable crystalline silica to further protect
workers.
Low-dose high-resolution CT scans required for workers in engineered stone industry
Now mandatory for workers whose health is at risk of exposure to respirable crystalline
silica
WA is the first Australian State to require these more effective scans
2. The AWU (Australian Workers Union) requests for help to protect the 600,000 Australian
workers who are breathing in silica dust every single day. Workers are exposed to respirable
crystalline silica (silica dust) in mines, quarries road and tunnel construction projects, in the
manufacture of cement and concrete and excavating. Our safety standards and their
enforcement in Australia are so shameful that even workers in the USA and Mexico have better
protection from silica dust.
The AWU is calling for a national regulation setting out minimum benchmarks to protect
workers in every affected industry, with tough penalties for employers who fail to comply. We
also need a compensation fund, backed by employers and industry, to help provide financial
relief to workers (and their families) diagnosed with silica related disease, and who are
struggling to return to work, and are adjusting to life with the devastating impact of their lung
disease. The Federal Government is working on reforms right now, and we must ensure that
they cover ALL workers who are exposed to this deadly dust.
February
34-year-old mother-of-two, Joanna McNeil contracts silicosis by inhaling crystalline silica.
Even though she worked in administration for seven years, the silica dust she would inhale
from the Boral Montrose quarry resulted in her contracting silicosis. Her lung capacity
deteriorated and she ended up struggling to breathe. Her office was in an admin building but
she would go home and could feel the dust on her face, on her lips and in her hair. Mrs McNeil
supported a national campaign launched by the Australian Workers Union (AWU) calling for
tougher regulations with minimum benchmarks to protect all workers exposed to deadly silica
dust. AWU raises concerns over the National Dust Disease Taskforce recommendations
providing extra protection for stonemason but not for other workers in construction, mining,
quarries and tunnels.
Joanna McNeill was diagnosed with silicosis after coming back from maternity leave.

3. March
A 38-year-old worker has been diagnosed with chronic simple silicosis and chronic bronchitis
with chronic obstructive pulmonary disease (COPD). The worker has worked in the coal
industry in New South Wales since 2016. The worker is employed by a contracting company
that conducts maintenance work at coal handling and preparation plants in the Hunter Valley.
The worker has previously worked at non-mining and mining workplaces in New South Wales
and other states of Australia. He was exposed to airborne dust environments at the non-mining
workplaces. The NSW Resources Regulator has completed an investigation into how the
worker may have contracted the disease. The investigation found that: ▪ the worker had worked
in the tunnel construction industry for twelve years with high-risk exposure to airborne dusts
containing silica from 2004 to 2012 ▪ there is a very high likelihood that the worker was first
exposed to dusts containing respirable crystalline silica (RCS) during this work period,
particularly when working in the tunnel projects in Sydney and further exposure in Brisbane
tunnel construction. The medical evidence and the worker’s employment history reasonably
establish that the worker’s condition is connected to his work in tunnel construction. Further,
there was no evidence to support a finding that the worker was exposed to hazardous levels of
atmospheric contaminant at any of his coal mining workplaces. The respiratory specialist
treating the worker reported that the worker’s condition is not attributable to his work in the
New South Wales coal industry. The worker’s condition is expected to remain stable if he
remains out of dusty environments. The worker is encouraged to maintain his scheduled
screening and lung function tests with Coal Service’s - CS Health. The worker’s continued
health is under the management of his general practitioner (GP) and specialist treating doctor.
April
Push to ban artificial stone benchtops amid rise of silicosis in tradespeople. Artificial or
engineered stone benchtops have seen rise in popularity in Australian homes as cheap and
attractive alternative to marble or granite. The National Dust Diseases Taskforce reported that
home renovation trends coincided with rising rates of silicosis among construction workers
who cut, polish and grind artificial stone. At this point in time, members of the National Dust
Diseases Taskforce agreed that a product ban on engineered stone should remain an option for
consideration, if strengthened regulations and enforcement activities fail to prevent new cases
of silicosis in the industry, or attempts at licensing fail.

Hudson Institute of Medical Research and Monash University's School of Public Health and
Preventive Medicine (SPHPM) have received more than $1.6 million in funding – part of $6
million nationally – from the Federal Government’s Medical Research Future Fund (MRFF)
towards research investigating ways to prevent and treat silicosis. Hudson Institute
inflammation researchers, Associate Professor Michelle Tate and Associate Professor Ashley
Mansell, were awarded $645,764 from the MRFF towards silicosis research. They will
collaborate with Monash Health and Monash University to collect and screen samples from
patients with mild and severe silicosis, and those without the disease. The samples will be
analysed for inflammatory markers and potential biomarkers to predict disease severity and
progression to developing silicosis. The research will also look at repurposing existing drugs,
and developing new therapies that dampen – but do not completely halt – this inflammatory
response to treat the disease and improve patients’ quality of life.

of silicosis.
June
Silica dust victims visit Australian Parliament House. Joanna contracted silicosis from working
in an administration role for seven year in a quarry. Kevin, worked for his company for almost
28 years and he was exposed to silica dust in the air, and frequently he could see the dust in the
air. He confirmed having inappropriate PPE, safety rules and regulations. Craig worked at a
Victorian quarry for 36 years until he was diagnosed with silicosis in 2019.
The National Dust Disease Taskforce delivered their final report following a two-year
investigation into the increased prevalence of silicosis in Australia. The report includes seven
major recommendations presented to the Minister for Health and Aged Care. The next step for
the Taskforce is to continue the implementation of final recommendations to support the
control and management of dust diseases in Australia. Although this report strongly focused
on the linkages between engineered stone material and silicosis, its additional aim is to start a
6. national conversation around the need for a comprehensive program of work designed to
fundamentally address the risks facing workers in industries that generate hazardous dust such
as silica.
Final Report to Minister for Health and Aged Care by the National Dust Disease Taskforce
Perth Radiological Clinic now performs very low dose CT scans which can detect the subtle
changes of early silicosis at a fraction of the radiation dose of conventional CT scans (less than
half of that normally received each year from naturally occurring background radiation from
living in Perth). Worksafe WA introduced new legislation in 2021 which requires workers at
risk of silicosis to be checked with CT scans, instead of x-rays. Perth Radiological Clinic’s
work means that Western Australian workers can now be reliably tested for silicosis.
July
Karl Hanson, a 42-year old Victorian stonemason was diagnosed with the incurable lung
disease silicosis, after having worked with engineered stone for 13 years and he often worked
in dangerously dusty conditions. At the time of the 7.30 news article, analysis of state figures
revealed about 470 stonemasons accepted compensation claims across Australia, nearly double
the number from less than two years ago. Mr Hanson is one of the hundreds of engineered
stoneworkers from around Australia who have been diagnosed with silicosis.

Gold Coast apprentices say they’ve been exposed to potentially deadly silica dust while dry
cutting during training in Victoria. Apprentices in Victorian TAFE courses are being taught
how to dry cut sandstone that contains high levels of potential deadly silica dust. Some are not
allegedly wearing masks.
September
The Lung Foundation Australia has called for increased Federal investment to tackle the
alarming rise of occupational lung diseases, particularly in the engineered stone benchtop
industry. The foundation says funds are urgently needed for the prevention, early detection,
treatment and support of Australians affected by silicosis. Lung Foundation Australia, in
response to the Taskforce, calls for funding to allow:
An expansion of our annual National Safe Work Month campaign from 2022
The development of a Dust Disease Management Plan
Expansion of Lung Foundation Australia’s support services
More research into dust diseases.
The foundation also wants to see tests for dust diseases included in the National Lung
Cancer Screening program.

October
RANZCR releases position statement on imaging of occupational lung disease. In Australia a
significant incidence of silicosis in workers exposed to the dust from high silica content
engineered stone has been identified. Imaging has a central role in the diagnosis and monitoring
of occupational lung diseases including disease resulting from exposure to engineered stone.
A common context in which this exposure occurs is in working with kitchen benchtops.
The spectrum of diseases associated with respirable crystalline silica includes:
Silicosis
Lung cancer
Chronic obstructive pulmonary disease (COPD)
Tuberculosis
Scleroderma
Rheumatoid arthritis
Chronic kidney disease
In Australian workers the spectrum of lung disease being identified includes accelerated
silicosis without calcified hilar or mediastinal lymphadenopathy, chronic silicosis complicated
by progressive massive fibrosis, and lymph node enlargement. Whilst there have been no
reported cases in New Zealand, similar patterns of disease are anticipated due to similar
products being used across both countries. Engineered stone workers may present for chest
imaging as part of screening programs or undergo imaging for unrelated reasons.
Craig Robertson and Kevin Weekes workers from Sibelco are in the news because of silicosis
diagnosis. It was not long before the pair had to leave Sibelco’s Lang Lang sand operation
south-east of Melbourne, which the company has since sold, because it was too dusty. Mr
Weekes is already unwell, suffering shortness of breath, joint pain and declining circulation
that leaves his hands and feet ice-cold. Mr Robertson, who is due for a check-up soon, says he
is fatigued. He said Sibelco did not offer appropriate alternative work, leaving him on Work
Cover with no employment prospects.
November
A Hobart stonemasonry business in Tasmania pleaded guilty to health and safety breaches that
exposed workers to the risk of developing the incurable lung disease silicosis. In court
documents, WorkSafe Tasmania alleges the company exposed six workers at its Cambridge
workshop and other work sites to the risk of inhaling respirable crystalline silica that would
result in exposing them to death or serious injury from developing silicosis. The workers
include two stonemasons, a stonemason apprentice, a labourer, an installer and a water jet
operator. Their work included wet and dry grinding and cutting of stone products, including
engineered stone, fabricated for kitchen benchtops.
Victorian government introduces Australia’s first licensing regime for workers fabricating
engineered stone benchtops. This regime require those working with engineered stone to
9. demonstrate compliance with safety measures and obtain a license by November 2022, failing
which, manufacturers will be unable to supply them with stone products. The National Dust
Disease Taskforce recommended adopting this measure. The changes are part of the new
Occupational Health and Safety Amendment (Crystalline Silica) Regulations 2021, which also
makes the state-wide ban on uncontrolled processing of engineered stone permanent.

Trials of a new piece of technology which detects dangers levels of respirable crystalline silica
in the air have commenced in Sydney. This game-changing technology can detect dangerous
levels of respirable crystalline silica (RCS) IN REAL TIME. The Trolex Air XS Silica Monitor
has been partly funded through SafeWork NSW’s Australian government, which is drawing a
lot of interest on Australian TV. The detector is part of the New South Wales Dust Strategy
2020-22, which aims to protect workers from dust diseases such as silicosis and asbestosis
which is caused by breathing in RCS particles, and asbestosis. The detector measures levels of
silica dust in the air in "real time", providing an alert to workers if they are being exposed to
potentially dangers levels of silica dust. It is hoped that the trials will be successful and the
detectors will be available commercially by the end of the year.
Trolex AirXS world’s first real-time silica dust monitoring device in action in NSW.
10. December
The release of the Workplace Safety Legislation and Other Matters Amendment Bill 2021
which was introduced in Parliament today. The proposed legislation will allow workers with
eligible diseases to access lump sum payments without the need for stabilisation. It will also
allow injured workers who have already received compensation for silica-related diseases to
make a subsequent application for damages if they develop a further related disease or injury
down the track. Further reforms in the Bill will improve access and deliver better support to
families of deceased workers, with weekly pension payments for children with disability to be
extended from the age of 16 to the age of 25. The Victorian State Government recognises the
progressive and ongoing nature of occupational diseases such as silicosis and the need for
reform. The changes will have a big impact on affected workers and their families. To date in
Victoria, tragically, four workers have died from silica related illness and WorkSafe has
accepted 59 claims for silica related diseases since the start of this year.
In recent years silicosis has been synonymous with engineered stone in kitchens. But in other
industries like tunnelling, thousands more workers are in danger of developing this deadly dust
disease. Chanel 10’s The Project ran this story this evening on Shane and his catastrophic
diagnosis of silicosis and rheumatoid arthritis as a result of his job as a road tunneller. It’s not
just stonemasons who face the silicosis risk, the problem is far broader and deeper than anyone
has imagined to date.
