Dust Diseases or
Dust Diseases Compensation in NSW

Silicosis is caused by inhalation of respirable crystalline silica dust. It is most commonly associated with:

• Engineered stone fabrication
• Stonemasonry
• Construction and demolition
• Tunnelling
• Mining

When silica dust is inhaled, microscopic particles lodge in the lungs and trigger progressive inflammation and scarring (fibrosis). Over time, this can lead to:

• Persistent shortness of breath
• Chronic cough
• Reduced lung capacity
• Respiratory failure
• Increased risk of lung cancer

There are different forms of silicosis:

• Chronic silicosis (developing over many years)
• Accelerated silicosis (developing within 5–10 years of high exposure)
• Acute silicosis (rapid onset after intense exposure)

In recent years, accelerated silicosis has been diagnosed in younger workers in the engineered stone industry across NSW.

Silica-Induced Lung Cancer

Prolonged silica exposure significantly increases the risk of lung cancer. Where medical evidence links lung cancer to occupational silica exposure, compensation may be available under NSW dust disease legislation.

Medical research increasingly recognises that silica dust exposure can also trigger autoimmune disease, not just lung scarring.

Silica can:

• Disrupt immune system regulation
• Cause chronic inflammatory responses
• Trigger abnormal immune activation in susceptible individuals

Recognised autoimmune conditions associated with silica exposure include:

Rheumatoid Arthritis

Workers exposed to silica — particularly in mining, foundry work, stonemasonry and construction — have a higher incidence of rheumatoid arthritis (RA).

Some individuals develop:

• Rheumatoid arthritis alongside silicosis
• Lung involvement associated with RA

Where occupational silica exposure materially contributed to the development or worsening of rheumatoid arthritis, compensation may be available.

Systemic lupus erythematosus (SLE) has been linked in medical literature to prolonged silica exposure.

Lupus can affect multiple organ systems including:

• Joints
• Skin
• Kidneys
• Lungs

These cases require careful specialist evidence to establish causation, but they may fall within the scope of occupational dust disease claims.

Systemic sclerosis — recognised under NSW dust disease legislation — is a serious autoimmune disease involving:

• Skin thickening
• Vascular changes
• Pulmonary fibrosis
• Internal organ involvement

There is an established association between silica exposure and systemic sclerosis, sometimes referred to in medical literature as “Erasmus syndrome” when occurring alongside silicosis.

Autoimmune-related claims are medically complex and require strategic preparation, but they may be compensable where linked to occupational exposure.

Asbestosis is a chronic lung condition caused by inhalation of asbestos fibres, leading to permanent scarring of lung tissue.

Common industries associated with asbestos exposure include:

• Construction
• Shipbuilding
• Power generation
• Manufacturing
• Insulation installation
• Demolition work

Exposure may also have occurred:

• During home renovations
• Through handling asbestos materials
• From secondary exposure (for example, washing a spouse’s contaminated clothing)

Symptoms typically develop decades after exposure and may include:

• Progressive breathlessness
• Chronic cough
• Reduced exercise tolerance

Compensation may still be available even where exposure occurred many decades ago.

Mesothelioma is an aggressive asbestos-related cancer affecting the lining of the lungs or abdomen.

Unlike asbestosis, mesothelioma can develop after very limited exposure.

Because of its seriousness, claims are managed urgently by the Dust Diseases Tribunal of New South Wales.

Compensation may include:

• Pain and suffering
• Past and future economic loss
• Medical expenses
• Care and assistance
• Family dependency claims
• Estate claims

Early legal advice is critical.

Coal dust pneumoconiosis — commonly known as black lung — is caused by prolonged inhalation of coal dust.

It primarily affects coal miners and workers involved in coal processing.

The disease causes progressive lung scarring and may result in:

• Chronic respiratory impairment
• Progressive massive fibrosis
• Permanent disability

Mixed dust pneumoconiosis (coal and silica exposure) may also occur.

Compensation may include workers compensation benefits and, where negligence is established, common law damages.

Not all dust-related claims involve classic pneumoconiosis or fibrosis.

Prolonged exposure to industrial dust, silica, coal dust, asbestos fibres, welding fumes and other airborne contaminants can also contribute to the development or acceleration of:

• Chronic Obstructive Pulmonary Disease (COPD)
• Emphysema
• Occupational asthma

These conditions may qualify for compensation where workplace or environmental exposure materially contributed to the illness.

COPD is a chronic lung condition characterised by persistent airflow limitation. While smoking is a well-known risk factor, occupational dust exposure is also a recognised cause.

Industries associated with occupational COPD include:

• Mining
• Construction
• Quarrying
• Foundries
• Metal processing
• Manufacturing

Long-term inhalation of dust and fumes can cause:

• Progressive shortness of breath
• Chronic cough
• Wheezing
• Reduced lung function

In some cases, workplace exposure significantly contributes to the severity or early onset of COPD, even where other risk factors are present.

Where occupational exposure materially contributed to the development or worsening of COPD, compensation may be available under NSW workers compensation law and, in appropriate cases, through the Dust Diseases Tribunal of New South Wales

Emphysema is a form of COPD involving damage to the air sacs (alveoli) in the lungs.

Occupational exposure to:

• Silica dust
• Coal dust
• Industrial fumes
• Chemical vapours

may contribute to or accelerate emphysema.

Workers with a history of heavy dust exposure who later develop emphysema may have a compensable claim where medical evidence supports a causal link.

These cases often require detailed respiratory specialist evidence to assess the extent to which occupational exposure contributed to lung impairment.

Occupational asthma occurs when exposure to workplace irritants or sensitising agents triggers asthma or significantly worsens pre-existing asthma.

Common workplace triggers include:

• Silica dust
• Grain dust
• Textile fibres
• Chemical fumes
• Isocyanates
• Industrial vapours

Symptoms may include:

• Wheezing
• Chest tightness
• Breathlessness
• Recurrent coughing

Occupational asthma may develop:

• Shortly after exposure
• Gradually over time
• After years of repeated inhalation of irritants

In NSW, if workplace exposure caused or materially aggravated asthma, workers may be entitled to:

• Medical expenses
• Weekly payments
• Lump sum compensation

In some cases, where employer negligence can be established, a common law claim may also be available.
