Leading medical staff in the UK, writing for medical journal ‘Thorax’, are calling for industries and governing bodies to follow Australia’s new legislation and ban the use of engineered stone, commonly used for kitchen worktops.
It comes after cases of silicosis linked to engineered stone exposure recently came to light globally. Workers who have been exposed to engineered stone quartz and dust are now being affected by and diagnosed with severe lung problems, linked to inhaling such dust. Earlier in the year, it had prompted the Australian government to act and ban the use, manufacturing, and production of engineered stone across the entire country.
Now the UK is being urged to do the same, with the first cases of silicosis related to engineered stone production have now been reported in the country. Various medical staff who have treated workers diagnosed with these cases of silicosis are calling for similar action to be taken in the UK as in Australia.
According to British newspaper i the first 8 cases of silicosis linked to engineered stone use have been confirmed, all of which are men. The average age of all 8 men is 34, with the youngest to be diagnosed just 27 years old. Of the 8 cases, 1 man has died, and 2 others have been referred for lung transplant assessments.
The article from i features an interview with one of the diagnosed workers, Malik al-Khalil, a stonemason who is just 31. After working with engineered stone for 5 years, Malik was diagnosis with silicosis, contracted after cutting engineered stone slabs in a small London workshop. Malik said, “I want to let all the people working in this work know what’s happening from this material” and believes the only solution to this growing problem is a nationwide ban of the product; “Of course [it should be banned] because the silicosis is coming from this material.”
It’s not just Malik and fellow diagnoses patients who are calling for engineered stone to be banned in the UK. Dr Johanna Feary, a respiratory consultant from the Royal Brompton Hospital where Malik al-Khalil is being treated, and lead author for ‘Thorax’, has also highlighted her concerns over exposed to the product. Dr Feary told i “We’ve been anticipating that we would start seeing cases in the UK at some point. That moment has arrived now.”
The team of doctors writing in ‘Thorax’, who highlighted the first 8 cases, have also called for a legal requirement to report cases of silicosis, as well as calling for the implementation of health and safety regulation for both small companies and national guidelines to treat and monitor for silicosis.

With an estimated 1 million people dying globally from the inhalation of dust in occupational environments every year, now is the time to protect your workers. Real-time dust and silica monitoring provides instant alarms and alerts for all workers at risk of dangerous dusk regardless of their application, processes or industry.
We’re continuously innovating real-time dust monitoring technology to give you access to the information to effect change and keep your workers safe from hazardous respirable dusts. With a range of dust and silica monitoring options, we’re here to help you protect your workers.
Whether that’s heavy-duty area monitoring for high dust loading environments, personal dust monitoring for individual monitoring needs, or silica monitoring for working environments with high respirable crystalline silica (RCS) content, such as stonemasonry, tunnelling or quarrying.
The AIR XS Silica Monitor leverages cutting-edge Optical Refraction Technology (ORT) to enhance workplace safety by providing real-time monitoring of respirable crystalline silica (RCS). Unlike traditional particle monitors, AIR XS distinguishes and measures RCS content, enabling immediate detection and response to harmful silica dust levels. This technology is crucial in combating occupational lung diseases such as silicosis, which affects millions of workers globally.
Current monitoring methods, like gravimetric sampling, are time-consuming and often deliver results too late to prevent exposure. In contrast, real-time silica monitoring offers immediate data, significantly reducing the risk of occupational silicosis by enabling prompt action to mitigate hazardous conditions. The importance of such real-time data is highlighted by cases like Joanna McNeill’s, who developed silicosis at the age of just 36. Her story, like many others underscores the necessity for continuous monitoring to protect workers from the threat of silicosis, regardless of their occupational environment.
Our real-time RCS monitor, AIR XS provides a real-time solution to this threat. Workers are not only alarmed and alerted when silica levels exceed legislative limits but can work to best practices by implementing AIR XS with the Hierarchy of Controls, supporting proactive measures to eliminate or minimise exposure to RCS. This move to real-time monitoring as a solution to the threat of silicosis has also been noticed by governing bodies, like the All-Party Parliamentary Group on Respiratory Health.
New test findings released, confirm the efficacy of a world-first real-time monitor for silica dust, which represents a revolution in the protection for workers exposed to respirable crystalline silica (RCS) dust.
As a leading workplace safety technology company, we have developed the AIR XS Silica Monitor, designed to protect workers against lung diseases such as silicosis by providing real-time readings of levels of crystalline silica in the air.
We have recently commissioned a leading occupational hygiene and laboratory testing organisation to conduct independent testing of the AIR XS. The results show the AIR XS repeatedly provided consistent, accurate, real-time data throughout an eight-hour testing period.
The testing demonstrates that AIR XS can improve worker safety by providing instant information to businesses and workers exposed to RCS, instead of having to wait up to four weeks to know their level of exposure to this killer dust, which is the current industry standard.
While the Australian Government recently implemented a ban on engineered stone, commencing 1 July 2024, the process most synonymous with creating silica dust, Group CEO Glyn Pierce-Jones said this ban alone would not solve the current health crisis caused by RCS.
“Silica dust is found in most building materials, so while banning engineered stone is a positive step, it’s not a holistic solution. The real issue facing the industry is the current archaic methods of testing for silica dust and the delay it causes in creating the safest possible workplace.”
The AIR XS is already being used in Australia to monitor RCS levels in many industrial locations.
Silica occurs naturally in soil, sand and granite; however, it is almost harmless in that state. Once those materials have been disturbed through construction or mining, silica dust is generated and can be inhaled into the lungs. This dust can cause silicosis, and other types of lung diseases and cancer, which are often irreversible and progressive.
Recent research from The Lung Foundation showed an estimated 600,000 Australian workers and between 40-50 million workers worldwide are exposed to silica dust across a wide range of industries including quarrying, construction, tunnelling, mining and many manufacturing processes.
The current approach to test for RCS is gravimetric sampling, the process requires collection, processing, and laboratory analysis of the sample, which is both time-consuming and costly for businesses. Direct-reading instruments offer businesses the ability to monitor employee safety on sites in real-time, eliminating the delays of weeks typically associated with potential RCS exposure.
Mr Pierce-Jones emphasised the urgent need for enhanced safety measures for anyone who may be in contact with silica.
“The current testing methodology for RCS only allows users to take an average reading over an eight-hour period and typically takes up to four weeks to produce a result,” Mr Pierce-Jones said.
“Our AIR XS Silica Monitor was designed to provide an accurate reading with immediate results, letting workers know when their health is in danger and allowing employers to respond in the most efficient manner.”
“These latest test results are another indicator of what we already knew at Trolex – that the AIR XS could be part of a desperately needed solution to an urgent health crisis.”
It’s estimated that over 40 million people worldwide are exposed to silica dust in the workplace. Respirable crystalline silica (RCS) contributes to one of the leading causes of death in the workplace, alongside other lung related illnesses. Due to this some of the industry’s most influential countries worldwide are making significant changes to regulations regarding silica exposure in the workplace.
In December 2023, Australia became the first country in the world to ban engineered stone due to rising cases of silicosis. From 1st July 2024, all use of engineered stone in Australia will be prohibited to protect workers from exposure to RCS in the workplace. Engineered stone is a manufactured material made from combining quartz or granite aggregates with resins and pigment and is a common material used in stone bench tops, often found in kitchens and bathrooms. It’s production often results in airborne RCS, leading to significant health risks to those working with it.
With reports that over half a million Australians are exposed to fine silica dust through stonemasonry and construction, figures suggest 103,000 of these workers are likely to be diagnosed with silicosis. The production and manufacturing of stone bench tops is a significant contributor to these statistics. The ban on engineered stone across the entirety of Australia is a step in the right direction to reduce the number of workers exposed to RCS and silicosis diagnosis in the future.
This ruling in Australia looks to have a set a precedent in influencing other countries to do the same. In May 2024, the first cases of silicosis linked to artificial stone countertops in the UK were reported, leading to calls for the material to be banned.
An estimated 600,000 workers are exposed to silica in the UK each year, and in Europe as a whole, 81% of those exposed are employed in construction or in manufacturing products used in the industry. After Australia became the first country worldwide to ban engineered stone in December 2023, UK kitchen company Herringbone announced they would also ban the sale of high-silica quartz worktop due to the risks posed to stonemasons.
Since speaking with their stonemasons about the risk of high quartz in engineered stone, Herringbone made the decision to become the first company in the UK to phase out the sale and production of engineered stone, as well as creating a petition to have the product completely banned in the UK, like in Australia.
In the US, the Biden administration has agreed to limit workers exposure to silica dust in mining, particularly when drilling for coal, ore and completing other mining operations. In April 2024, a ruling was announced to reduce the allowable silica dust levels in mining operations to 50 micrograms per cubic meter, with an action level at 25 micrograms, for an eight-hour workday.
The ruling will also update any respiratory protection standards for mining workers and in addition to silica dust, will also apply to diesel particulate matter and asbestos. The hope is that this will begin to reduce an estimated 1,067 deaths and 3,746 silica related illnesses in mining industries in the US and begin to make mining safer from the risk of RCS for the 55,000 American coal miners across the nation. The rule will come into action one year after its publication in April 2024.
With significant action being taken across major industries worldwide as of mid-2024 and onwards, protection for workers against respirable crystalline silica is becoming more of a high priority in workplaces. With banning of products known to produce dangerous levels of RCS, and with rule changes to limit exposure, workers short- and long-term lung health is becoming better protected than ever.
A manufacturer of prestigious natural stone, Burlington Stone have quarried for over 200 years across the English Lake District, extracting and crafting a diverse range of signature British natural slate and stone products.
Individuals across their workforce are often exposed to hazardous substances, most notably airborne dust, including silica dust. Burlington Stone trialed two XD1+ devices on their site for a month to see how real-time, personal dust monitoring would improve their safety processes.
After the trial, we spoke to Health and Safety Manager, Peter Walker, about the success of the trial and some of the major benefits which Burlington Stone’s workforce found deploying XD1+ Personal Dust Monitor units in their day-to-day processes.
Our AIR XS Silica Monitor, an innovative real-time respirable silica (RCS) monitoring device, has been deployed at a major railway operations project to monitor the levels of RCS which workers may be exposed to.
The Central Rail Systems Alliance (CRSA), an alliance between Network Rail, Balfour Beatty, AtkinsRéalis and TSO have been using an AIR XS unit to monitor the levels of RCS released when damaged rail tracks are replaced; when rail track is damaged or needs replacing, the ballast surrounding the track is disturbed and can release RCS. The AIR XS unit was supplied by our UK partners Sunbelt UK & Ireland.
The challenge faced by CRSA was to measure the level of RCS and accompanying dust being released into the atmosphere during the unearthing process of 425m rail and ascertain the level of risk associated for those working in the immediate and surrounding environments. The AIR XS unit was manoeuvred around the site in-line with project progress, so that working scenarios can be accurately represented in the data set.
Upon conclusion of the project, Madeline Dunn, the Health and Safety Advisor for CRSA praised the monitoring and recording capabilities of the AIR XS, saying “We have completed trials prior, however this is the only unit where it is measuring silica and not just general dust levels. We gained the knowledge that the exposure levels were actually higher than we anticipated with even low-level ballast disturbance.”

In this exclusive interview with Trolex, Gordon Sommerville shares his first-hand experience of the dangers of silica exposure and what you can do to protect yourself and others from the dangers of silica dust.
“The only cure for dusty diseases at the moment is not to let dust get inside the body, which means in order for silica induced diseases to be classed as 100% preventable, awareness of the hazard throughout the exposed population is required.”
Gordon, now a retired stonemason, was diagnosed with silicosis in 2015. He started his career working in the construction industry after leaving school in 1976 and soon became a stonemason and builder to trade. In such an environment, working on projects both large and small throughout his career, dust was everywhere.
“No matter what type of work I was carrying out or who I was working for, daily dust was involved — and lots of it. I did not realise dust was making me ill but during my career there were little clues which should have raised a red flag.”
Gordon’s aim in sharing his story is to inform, educate and highlight the dangers of exposure to silica dust and to give advice to individuals who work in similar industries on how to avoid the issues that he now faces as a result of silicosis.

Pennine Aggregates are one of the largest specialist aggregate and mineral processors in the UK. Based in Buxton, Pennine Aggregates are a global supplier to a wide range of companies, including ABC Industries as well as Sherwin-Williams, Cemex and Hansons in the UK.
Silicosis now causes a huge number of deaths across an increasing number of industries, from clothing manufacturing to construction; but the aggregates industry have one of the highest risk profiles for this fatal occupational lung disease. This meant that Pennine Aggregates grabbed the opportunity with both hands to trial the world’s first real-time respirable crystalline silica (RCS) monitor, the AIR XS Silica Monitor, to see how they could integrate it into their existing dust suppression processes.
Mark Dickinson, a director at Pennine Aggregates said: “It’s really important to us as a business that we are using every tool that’s available to keep our workers safe and we were really excited to have the chance to see what impact using the first real-time RCS monitor would have on our processes and on workforce morale.”
In April 2022, we supplied them with an AIR XS unit to test their processes across two main site locations over a six-week period. For Pennine Aggregates, it wasn’t that they didn’t have dust suppression in place, but more that they didn’t know exactly how much dangerous silica dust each of their processes were producing.
Mike Thompson, QHSE Manager said: “We were asking ourselves right across the business – is our dust suppression actually getting the right amount dust out of the environment, as quite frankly, before we installed the AIR XS on our site we just didn’t know.”
Pennine Aggregates ran the AIR XS Silica Monitor on their site over a six-week period on each of the processes where they had put in place new dust suppression systems.
The effects of silicosis in the stone industry is not an unknown issue.
But to what extent are stone workers aware of this issue? Are the specific causes of silicosis in the stone industry common knowledge?
A scientific report from nature.com highlights the difference between engineered stone and natural stone, in relation to their silica content, shedding some light on where the cause of silicosis could lie in the stone industry.
Silicosis is one of the most dangerous respirable lung diseases in the workplace, especially when exposure to harmful silica dust is a common occurrence, such as in the stone industry.
It is estimated that globally, 40 to 50 million workers are exposed to silica dust in the workplace.
The Natural Stone Institute guide to awareness and prevention of silicosis determines that exposure to respirable crystalline silica (RCS), specifically in the stone industry comes from cutting or grinding materials, most commonly which contain quartz, is composed of silica dust.
The purpose of the study from nature.com was to see, in relation to RCS, what the most threatening scenario was for worker’s health, in real time, when working with different compositions of stone.
In the study, 12 engineered stones were assessed against three natural stones – white marble, white granites and black granites. By dry-cutting all stones, silica dust was captured in a closed environment and subjected to various assays to determine both chemical and physical properties.
The 12 engineered stones’ silica content varied from one another, and the total RCS content made up of quartz and cristobalite ranged from 70.4% to 90.9%. By comparison, the natural stone’s silica content ranged from 3.5% to 30.1%, marking a clear difference.
As well as this, the dry-cutting of engineered stone generated finer RCS particles with one engineered stone having an average size of as little as 190 nanometres, meaning it could reach deeper in the lungs, in turn causing more damage. Contrastingly, the smallest average particle size of the natural stone was black granite, with an average size of 503 nanometres.
The results of this study concluded that silica dust emissions from engineered stones had a much higher concentration of quartz and cristobalite, therefore having a higher silica content and subsequently more damaging impact on respiratory health.
Ultimately, the report concluded that the higher the silica content of the stone, as well as the smaller size of RCS particles, the more dangerous it is to respirable health.
The Natural Stone Institute conclude in their guide to occupational silicosis that there is no cure for silicosis; however, “with the proper equipment, training, vigilance and continual monitoring, you and your shop floor can be free of the dangers”.
Being aware that harmful silica dust is higher within engineered stone, compared to natural stone, and by monitoring for this, as well as using correct respirable protective equipment (RPE) when working with engineered stone, it allows for correct precautions to be taken to avoid silicosis.
We’ve developed the world’s first real-time silica monitor, the AIR XS Silica Monitor, and, along with other health and safety controls, this is one of the tools that will help to prevent occupational silicosis for those exposed to harmful silica dust in the workplace.
