Silica dust exposure at work: NSW workers compensation guide

Material and process, including wet or dry method and tools used. Frequency, duration, distance, enclosure, extraction and respiratory protection. The task history should quantify force, weight, repetition, duration, posture or exposure rather than rely on a label such as “overuse”.

Concrete, masonry, tunnelling and demolition workers. Stone processing, benchtop and construction workers. Rosters and role records can identify who performed or observed the same work cycle.

Silicosis or dust disease. Occupational lung disease. A symptom label does not replace a diagnosis or a reasoned opinion linking that diagnosis to the measured work history.

Silica risk control plan, SDS and approved training records. Air monitoring, health monitoring and silica worker register material. Early records should show when symptoms began, changed and were reported, even where there was no single accident date.

• Tool extraction, water suppression, vacuum and respirator fit records.

Silica risk control plan, SDS and approved training records. Air monitoring, health monitoring and silica worker register material. The strongest task history connects objective work records with the symptom and treatment chronology.

• Tool extraction, water suppression, vacuum and respirator fit records.
• Employment, site, material and task chronology across all exposure periods.

Occupational and respiratory physician history with exposure intensity and duration. Lung function, imaging and other tests interpreted for the suspected disease. Medical causation evidence should address the diagnosis, measured work exposure, pre-existing conditions and relevant non-work factors.

• Smoking, other dusts, previous employment and non-work respiratory disease addressed.

Material or process did not create significant RCS exposure. Controls and monitoring show exposure was low. The insurer’s written reasons should be answered with evidence directed to the actual causation or eligibility issue.

Monitoring, respiratory review and treatment depend on the diagnosis and clinical advice. A normal earlier screening result does not answer every later question, but further testing still requires medical justification. Treatment and restrictions should be tied to the accepted diagnosis and the work factor that needs to be reduced or avoided.

Restrictions may remove further silica or dust exposure and limit exertion where medically supported. Suitable duties must identify actual airborne-contaminant risk, not only a different job title. Sustainable capacity depends on the complete shift and repeated exposure, not whether one movement can be demonstrated once.

A Dust Diseases Care claim is not assessed as an ordinary section 66 WPI claim merely because imaging or lung function is abnormal. The dust-disease scheme considers the diagnosis, qualifying NSW work exposure and disability under its own legislation. A separate ordinary-scheme respiratory impairment would require its own legal basis and the applicable NSW assessment method. Dust Diseases Care applies its own statutory diagnosis, exposure and disability criteria; this page is not an ordinary section 66 WPI estimate. WPI is assessed after stabilisation using the NSW method for the accepted diagnosis; exposure duration or pain alone does not set a percentage.

A prescribed work-related dust disease generally requires investigation through icare Dust Diseases Care. Coal-mine workers use a separate coal-industry scheme. Exposure concern, register status or screening alone does not establish entitlement under either pathway. Workplace-safety, public-health or medical-screening activity may run alongside the dust-disease process, but it does not determine compensation, disability or payment entitlement. Any other compensation or insurance pathway remains separate and has its own eligibility rules.

Build a dated work history using measurable facts such as material and process, including wet or dry method and tools used; frequency, duration, distance, enclosure, extraction and respiratory protection. Match the diagnosed condition and symptom chronology to workplace records, prior history and relevant non-work factors. The purpose is to match the disputed decision to reliable work and medical evidence, not to promise an outcome.
