Silica dust monitoring

Using real-time silica monitoring technology to combat occupational silicosis

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 testing proves efficacy of real-time silica monitor that could save thousands of lives

    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.”

    AIR XS Silica Monitor deployed to monitor RCS levels during replacement of rail track

    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.”
