Silica And Mesothelioma: Occupational Exposure Concerns – Silicosis is a lung disease caused by inhaling respirable crystalline silica. Silicosis is a type of pulmonary fibrosis of which there are three types:
Chronic silicosis can develop after short-term exposure to very high levels of airborne crystalline silica (silica dust), such as less than a year to several weeks, and causes severe inflammation and protein effusion in the lungs.
Silica And Mesothelioma: Occupational Exposure Concerns
Accelerated silicosis can develop after 3 to 10 years of exposure to moderate to high levels of silica dust and cause inflammation, protein buildup in the lungs, and scarring of the lungs (fibrotic nodules).
Mesothelioma Cancer, Causes, Symptoms, Diagnosis, Prognosis & Treatment
Chronic silicosis can develop after prolonged exposure (more than 10 years) to minor silica dust and cause fibrotic nodules and shortness of breath. This may include progressive massive fibrosis, in which fibrotic nodules coalesce in the lungs.
When materials containing crystalline silica are cut, drilled or ground without proper controls, dust particles are released into the air. Silica particles smaller than 10 microns (respirable crystalline silica) can be inhaled deep into the lungs. These particles can be invisible and are less than 1/5 the diameter of a human hair.
Recent studies estimate that future occupational exposure to respirable crystalline silica (RCS) will result in more than 83,000 cases of silicosis. In addition, more than 10,000 cases of lung cancer are predicted due to occupational exposure to RCS (Curtin University 2022).
Forms & Resources
Between 2010-2011 and 2019-2020, there were 412 workers compensation claims for silicosis in Australian jurisdictions covered by the WHS Model Laws (SWA 2022).
In 2022, all governments responded to the final report of the National Task Force on Dust Diseases, which outlined the commitment of Australian and state and territory governments to reduce the incidence of silicosis and other dust diseases in workers and improve the quality of life of those affected. and their families.
Australia’s Occupational Health and Safety (WHS) Strategy 2023-2033 sets a target of zero new accelerated cases of silicosis by 2033.

In 2022, the ACT commissioned the Silica Dust Exposure Research Perspectives Project, which explored attitudes, views and practices in the ACT. The study included one-hour interviews with more than 30 different stakeholders, including employees, safety officials, customers, business owners and more. We found the industry’s silica safety challenges, attitudes and practices. Key findings identified:
Between 2019-20 and 2021-22, there were a number of silicosis-related compensation claims for public sector workers (as of 28 February 2023).
By 2022, the ACT has banned the dry cutting of all silica-containing materials and technical stones, and has introduced controls to be used when altering these materials with power tools.
How To Stop Silica Becoming The New Asbestos
In the past 30 months (January 2021 – June 2023), ACT has carried out 48 proactive and reactive inspections involving silica/rock cutting.
During the same period, the team issued 53 enhancements and 57 prohibition notices. ACT also issued eight (8) infringement notices totaling $30,720.
Curtin University 2022, The future burden of lung cancer and silicosis from occupational exposure to silica in Australia: a preliminary analysis Asbestosis is a chronic lung disease caused by repeated long-term exposure to toxic asbestos dust, while silicosis is a respiratory disease caused by inhalation. silica dust. Both diseases cannot be cured.
Measuring Crystalline Silica In Stone: Determine Your Stone’s Risk
Asbestosis and silicosis have emerged in recent decades as cancers that can seriously harm the health of workers exposed to hazardous materials. Both asbestos and respirable crystalline silica are listed on the Occupational Safety and Health Administration (OSHA) list of toxic and hazardous substances and their use is regulated by US law. to help reduce the risk of occupational exposure. The construction industry is a common area where asbestosis and silicosis are involved, although it affects many other environments. In this article, we will explore the similarities and differences between asbestosis and silicosis.
We can help you protect your workers from toxic asbestos or silica dust with our asbestos testing and silica exposure monitoring services. We serve clients in Massachusetts, New Hampshire, Maine and other parts of New England. Contact us now!
Below is a chart comparing asbestos and silicosis in terms of disease causes, symptoms, people at risk, method of exposure, regulations, and more.
Protecting Construction Workers From Silica Dust: The
In both cases, prevention is the best cure for asbestosis and silicosis. Employers and building managers must take care to ensure that people are not exposed to toxic dust caused by nuisance materials containing asbestos or crystalline silica. To avoid this, you need to make a plan and follow it. The levels and exposure over time of these two airborne particles should be assessed periodically and especially when activities are taking place that may cause them to be released into the air.
No. Although silica and asbestos have many similarities, they are different. Both are silicate minerals that cause lung disease, but one of the biggest differences is how people are exposed. Unlike silica found in solid materials, asbestos is easily dispersed into the air.
No, silicosis is caused by inhaling silica dust. Asbestos is known to cause asbestosis and mesothelioma. However, both asbestos and silicon dioxide are dangerous to health.
Occupational Exposure To Respirable Crystalline Silica In Municipal Household Waste Collection And Road Cleaning Workers
Both diseases are incurable and irreversible, but are caused by different silicate minerals. Silicosis is caused by exposure to crystalline silica, while mesothelioma is a rare and aggressive type of lung cancer linked to exposure to asbestos.
Asbestosis is a fibrotic lung disease and exposure to airborne asbestos fibers causes it along with other types of cancer such as ovarian and laryngeal cancer.
It is important to have a properly qualified, experienced and independent company to assist in exposure planning, assessment and monitoring.

Pdf] Case Studies Silica Exposure During Granite Countertop Fabrication
Exposure to asbestos causes malignancies such as lung cancer and malignant mesothelioma. However, the effects of asbestos fibers on immunocompetent cells have not been well studied. Asbestos is physically composed of a fibrous substance distinct from silica particles, which is a particulate matter, although chemically it is a silicate mineral. Since silicosis patients with prior exposure to silica particles often suffer from pulmonary and autoimmune diseases, it is clear that exposure to silica impairs immune tolerance. Similarly, asbestos can alter the immune system of people exposed to asbestos. Since malignancy can occur after exposure to asbestos, attenuation of antitumor immunity in asbestos exposure is an important area of research. We looked at the effects of asbestos fibers on T lymphocytes, such as CD8+ cytotoxic T lymphocytes (CTL), CD4+ helper T (Th) and regulatory T (Treg) cells, and showed that
