Summary
Since 2015 there has been an alarming re-emergence of silicosis in Australia, primarily affecting workers who fabricate and install kitchen benchtops from high silica content artificial stone materials. Cutting, grinding and polishing artificial stone can result in generation of high levels of very fine silica dust particles. When inhaled by workers these particles can cause lung scarring (silicosis), which may require lung transplantation or lead to premature death. Silica dust exposure also increases the risk of autoimmune diseases such as scleroderma, as well as lung cancer.
WorkSafe Victoria has commissioned MonCOEH to fill gaps in evidence related to this re-emergence of silicosis around prevalence, burden of illness and risk factors. This evidence will assist WorkSafe Victoria to address the occupational health issues in this industry and to inform the advice provided to employers about their occupational health and safety obligations.
WorkSafe Victoria launched a free health assessment program in 2019, with the aim of screening all Victorian stone benchtop industry workers for silica-related diseases. MonCOEH’s work comprises two project domains, both of which leverage data from this screening program.
1. Screening Registry: records relevant occupational and health information from workers participating in the WorkSafe Victoria free health assessment program.
2. Silica-associated Disease Registry: captures medical information on workers with possible or diagnosed silicosis and other silica-associated conditions from all industries.

6. Other Information |
Please describe plans that are funded or most likely to be funded
|
|
Victoria has an estimated 1,400 workers in the stone benchtop industry who may be exposed to silica dust through work-related activities. These projects will help WorkSafe Victoria deliver evidence-based advice to employers to support their health through better prevention strategies, improved health screening and early diagnosis. The data captured by the registries may also inform further epidemiological studies into the emerging condition.
